And the correct feeding of clematis is the three components of the success of growing these plants. Each of them is very important in itself, but feeding should be discussed separately.
When to start feeding?
If the land was well filled with fertilizers before planting, then additional feeding begins only after two, or even three years. But when the soil is poor, it is necessary to sprinkle humus or well-rotted compost mixed with wood ash on the bases of the bushes in the first spring or autumn - 1 - 2 handfuls per bucket. This is especially true of young specimens, whose root system is not yet sufficiently developed.
What and how to feed?
To feed clematis, experts recommend alternating mineral fertilizers with organic matter diluted to a liquid state. The only thing to remember is timely and sufficient watering. Clematis are very fond of water and do not tolerate high concentrations of nutrients in the soil. Therefore, fertilizers are applied in small portions, and the plants should be watered abundantly before applying them.
All dressings must be consistent with the periods of clematis development. In the spring, at the end of May, when there is intensive growth and development of young shoots, they need to be given more nitrogen. Diluted mullein or poultry droppings at a concentration of 1:10 or 1:15, respectively. In the absence of organic matter, urea can be used - about 20 grams per square meter of planting area. Fertilizers must first be dissolved in water.
After the shoots have grown, foliar nutrition should also be given to clematis - spraying with a weak solution of urea in a concentration of no more than 3 grams per liter of water.
During budding, nitrogen is also required by clematis, but phosphorus and potassium come to the fore. A complex mineral fertilizer such as "Kemira Lux", "Riga Mix" or "Nitroammofosk" is suitable here, which should be supplemented with a solution of fermented mullein or an infusion of weed out weeds. The use of traditional flower mixtures is not excluded. But, choosing them, you need to pay attention to the fact that there are no components containing chlorine, which is completely contraindicated for clematis.
The next stage of feeding begins when the plants have already faded. Unless, of course, for some reason it is not required to shorten the flowering period. In August, phosphorus-potassium mixtures are used, for example, "Kemira Autumn". The supply of nitrogen to the roots of clematis at this time should already be limited so as not to cause an excessive increase in green mass, which is undesirable on the threshold of autumn.
In addition, it is very useful to spray all types of clematis with weak solutions of potassium permanganate and boric acid - 2 grams per bucket. This should be done throughout the summer, once a month.
By September, feeding stops altogether. It remains only to fill the soil with wood ash, which is covered up under bushes in the middle of the month. For each plant, about 2 glasses of well-sifted are consumed.
In total, at least 4 dressings must be done during the season, not counting intermediate spraying. And clematis will delight you with lush flowering, healthy appearance and good growth.
Clematis are plants that need care in both summer and winter. In order for the liana to bloom profusely, you should carefully consider this procedure. If the plant is properly prepared for frost, then it will delight its owners with large and bright buds.
Preparing for winter
Caring for clematis before the onset of cold weather plays an important role in their further development. Despite the fact that the plant has adapted enough in our area, its southern roots still make themselves felt. Gardeners who have been growing these plants of unusual beauty on their territory for more than one year know that their flowering depends on the correct pruning, watering and fertilization.
If summer and spring dressings are enough for some lianas, then for clematis they are mandatory in the later period of the year. It is especially necessary to fertilize if the flower grows in poor lands.
If clematis is not cut and wrapped for the winter, they can completely die or freeze in places. Therefore, in order to avoid negative consequences, it is necessary to wrap the plant well before the onset of cold weather, and also remove unnecessary shoots. You will learn how to do this in the article.
Work execution time
In order for the vine to bloom profusely, it is necessary to trim its shoots throughout the year. There are several categories of this plant care, which are slightly different.
The main groups of clematis:
- First group... These are wild varieties, Texas and Oriental vines. They need to remove dry and damaged twigs after foliage falls. Cut off shoots on such bushes should be in the spring. If this is not done, then the plant will lose its shape. Over time, such vines become bare, and the buds appear only in the upper part.
The flowers of this group are cut only in the spring for the first two years. Then the procedure must be carried out in the summer.
Bushes that are two years old should remove all branches, leaving one bud at a time. This should be done from January to February.
- Second group... These are vines that bloom twice a year: from May to June and from August to September. Such flowers are cut in the last month of autumn and summer. This is because the buds are formed on last year's branches. The summer procedure should be carried out in June, when the flowering ends.
- Third group... These are the most popular species to be found in any garden. These include hybrids and herbaceous varieties. You can observe their flowering in early July. Such vines are cut only in autumn. It is best to do this in October or early November.
Important! Plants of the second group should be strongly trimmed every 5 years. This is necessary so that the bush is lush, and the flowers bloom at eye level.
Fertilizers and feeding
If the plant was well fertilized during planting, then the next procedure should be carried out in the third year of the vine's life. But in the case when the soil is scarce, it is recommended to apply fertilizers in the first autumn.
Before feeding, you should water the flower abundantly for several days before the procedure.
Advice! The plant does not tolerate an overabundance of drugs, so they should be applied in a diluted form.
As a top dressing, you can use humus, compost, as well as potassium-phosphorus fertilizers. If humus is used for fertilization, then its amount per one trunk circle should be 10 kg. It is not recommended to use preparations containing nitrogen. This component contributes to the active growth of green mass, which is not at all necessary for clematis in the fall.
Also, before the shelter, the base of the bush should be strewn with wood ash and tamped well. It should be well crushed. It is better to sift it before using it. The optimal amount is 0.5 kg of substance per bush.
In addition to organic products, clematis can be fertilized with mineral preparations. They must be used very carefully. It is worth adding such compositions according to the indicated proportion on the package. If you observe the correct amount of dressings throughout the year, then in the fall they can not be used at all.
Advice! The last feeding should be done in the month of September.
Caring for clematis in the fall also includes spraying the root part. This is done immediately after pruning the shoots.
To do this, you can use:
- two percent ferrous sulfate;
- one percent solution of Bordeaux liquid.
This procedure should be used for all types of vines. It is necessary in order to protect plants from the development of dangerous fungal diseases.
Pruning clematis
This is an important part of grooming and should be treated with special care. A lot depends on the correct pruning. First of all, this is the full development of the root system.
Types of plant pruning:
- sanitary (removal of dry shoots and leaves);
- formative (necessary for better growth of vines);
- winter (protects the flower from freezing).
Clematis is a plant whose leaves do not fall off on their own in the fall. Therefore, in order for the flower to have an attractive appearance in spring, dry leafy plates should be removed on your own.
Advice! It is also necessary to cut off damaged leaves from wintering branches.
The pruning method depends on the type of plant and how old it is. Some species do not need this procedure at all. As for young flowers, they should be cut off completely, leaving no more than 30 centimeters of shoots above the ground.
The most effective is three-tiered pruning. It can be applied to a variety of plant varieties. If you use this method, then the plant will certainly please with its appearance in the spring.
First tier... No more than four shoots are cut off. They are each pruned one meter above the ground.
Second tier... Each of the four branches is trimmed 0.5 meters above the ground.
Third tier... At this stage, 4 shoots are also used. It is important to ensure that two to three buds remain above the soil during the pruning process.
The remaining branches will need to be removed at the root, and those that have been cut should be neatly folded on the surface of the ground.
Shelter for the winter
This procedure should be carried out at the end of autumn. This is best done in the second half of October or early November. Liana easily tolerates small frosts, but experimenting is not worth it. In a winter with little snow, the shoots of clematis are very quickly damaged, which will negatively affect its flowering.
The plant should be covered after the pruning and processing of the vines is done. For the procedure, you can use dry tree branches, weathered peat, wood shavings, dry leaves and other materials.
In order for the vine to feel good in frosts, it is worth pouring a layer of dry earth on top of the material. It is also recommended to additionally protect it with a thick layer of snow. Varieties that need insulation must be shortened to 150 centimeters.
The principle of the procedure depends on the variety and type of flowering:
- Clematis, in which buds appear on the twigs of last year, are the most frost-resistant. These include large-petal, alpine, spreading and mountain varieties. In regions with relatively warm climates, the plant can winter right on the supports. Cutting off the shoots is not necessarily sufficient to protect the root system from severe frost. The wrapping should be carried out at a height of 40 centimeters from the ground. It is enough to use a good layer of dry soil and leaves.
- A plant that forms buds on both last year's and young branches needs pruning. After removing unnecessary shoots, the vine must be removed from the support and leveled. Carefully roll the unraveled lashes into a ring and put on the ground. Sprinkle dry leaves on top and cover with non-woven material. They can be either agrofibre or lutrasil.
- Lianas, the flowers of which appear on young shoots, are the most common in our country. They are unpretentious to care for and tolerate frost well. Such clematis, after pruning, only need hilling. These include hybrid varieties. It is not necessary to cover such flowers additionally.
Conclusion
In order to understand how to properly cover a plant, it is enough to know its variety and how high it weaves up. If you follow all the rules of autumn care, then the plant will certainly delight you with abundant flowering.
Clematis, they are also clematis, vines and "grandfather's curls" - perennial vines, ideal for decorating facades, hedges, gazebos and arches. In order for their flowering to be abundant and pleasing to the eye, you need to know how to feed clematis in different periods of the growing season. In this article, we will consider the rules for spring feeding of these plants.
During the period of active growth - in spring and June - you need to feed clematis with nitrogen. With a lack of this element, the flowers slow down growth, the foliage turns yellow, the shoots become weak, the inflorescences do not bloom.
In July, when the budding begins, it is recommended to fertilize the plantings with compounds containing phosphorus and potassium (their shortage can be detected by darkening of the leaves).
If you overfeed the plants with nitrogen, they will give abundant growth of greenery and will not begin to lay flower buds, therefore this element is contraindicated during the flowering period.
In autumn, plantings are re-fed with phosphorus and potassium.
How to fertilize clematis?
All the elements necessary for the plants in question are contained not only in mineral complexes, but also in organic substances, to which the flower reacts perfectly. The most rational is the method of alternating different types of fertilizers.
Mineral dressing
To stimulate the growth of green mass, the best means are urea and ammonium nitrate. Their solutions are prepared at the rate of 1 tbsp. spoon for 10 liters of water. Consumption for young seedlings - 5-6 liters, for adult plants - 10 liters.
Superphosphate (20 g per bucket of water) and potassium sulfate (10 g for the same volume of liquid) are used as a phosphorus-potassium dressing for planting buds.
After transplantation, the Zircon remedy can help to adapt to the new conditions, which should be used according to the instructions on the package.
Organic fertilizers
Natural remedies, in addition to nitrogen, phosphorus and potassium, contain valuable trace elements. They are rich in vermicompost, which creates a beneficial microflora and enriches the soil with carbon dioxide. From natural products, it is advisable to use slurry from mullein (1: 8), horse manure (1:10) or bird droppings (1:16). Solution consumption per 1 bush - 10 liters.
In order for the flowering to be active, it is not necessary to fertilize clematis at this time.
Folk remedies
With high soil acidity, nutrients are poorly absorbed. Prescription milk of lime can lower the pH level: 0.15 kg of chalk or slaked lime and 0.1 g of wood ash are diluted in a bucket of water. The mixture is poured over the soil under the clematis in spring and early summer.
An excellent nitrogen fertilization for clematis is ammonia dissolved in water in a ratio of 1 tbsp. spoon for 10 liters.
The indicated dosage should be strictly observed: a violation leads to an excess of greenery to the detriment of the formation of flowers, as well as poor resistance to fungal diseases.
In hot dry weather, it is useful to fertilize clematis with boric acid, which has the following advantages:
- stimulates growth;
- increases the content of chlorophyll;
- reduces the negative effects of hot weather;
- increases the number of colors.
The lack of boron is indicated by the falling of the buds. It is necessary to introduce the substance under the root only if there is confidence in its deficiency. Foliar spraying with a 0.1% solution is safe.
Many gardeners use bone meal as a phosphorus fertilizer. In addition to phosphorus, it contains potassium and other beneficial substances.
Formulations for foliar dressing
This procedure ensures that the nutrients reach the foliage quickly. For applications, use ready-made products: Master, Flower solution, Aquarin.
It is necessary to spray the preparations in the evening so that the drops of the solution do not provoke a sunburn. The solution should fall not only on the outside, but also on the inside of the sheet. The procedure should not be carried out more often than after 10-15 days, otherwise there is a risk of overfeeding the plants.
Foliar treatments can be carried out no more than 4 times during the whole season.
Top dressing scheme
If clematis were planted in fertilized soil, then they do not need to be fertilized in the first 2-3 years. But when planting in depleted soil, you need to start adding food immediately.
How to feed clematis in spring before flowering? When planting seedlings in early spring or autumn, humus or compost is added to the holes; on acidic soils, additional chalk or lime is added. It is useful to add ash to any soil, as well as superphosphate. The organo-mineral agent "Universal OMU" has proven itself excellently, which is recommended to be applied when planting clematis. It not only contains nutrients, but also retains moisture.
After planting according to the above rules, for the first three years, the plant is fertilized with only a small amount of organic matter in the form of dry compost or humus, distributed over the soil surface.
In subsequent years, fertilizer for clematis is applied in the spring, alternating nitrogen mineral compositions and infusions of organic substances, as well as milk of lime in the sequence:
- After winter, the first spring feeding of clematis is done with infusion of bird droppings or mullein. An alternative option is a solution of urea or ammonium nitrate.
- In April, plantings are sprayed over the leaf with a weak solution of urea (25 g per 10 l of water).
- May is the time of the deoxidization procedure (on acidic soils). It is carried out with milk of lime or dolomite flour.
- With the beginning of the formation of buds, fertilizing with phosphorus-potassium compounds is carried out.
In total, there should be more than four main fertilizers in a season. Additionally, in the summer, you can feed clematis by spraying with a solution of boric acid with the addition of potassium permanganate or other formulations for foliar dressing.
Common mistakes gardeners make when fertilizing clematis
In order for flowering clematis to please the eye for a long time, you need to remember some of the features of growing:
- Fertilization should not be continued after the flowers have bloomed.
- Do not use substances containing chlorine.
- Fresh manure is not recommended.
- Clematis do not like waterlogging of the soil, so it should be watered in spring once a week, but abundantly. With frequent rains, ash is scattered around the stems to reduce the negative consequences.
- Dry fertilizing is applied to wet soil, and to dry feeding it is combined with irrigation.
- All weeds must be removed before fertilizing.
- In plants that have reached the age of seven, the roots go to a depth of more than 1 m. In order for water and nutrient solutions to reach the roots, irrigation pipes are dug in.
These simple tips will help you achieve lush blooms for years to come.
Lozinka, clematis, grandfather's curls - all these are popular names for decorative clematis. The climbing plant is very popular with gardeners and is used for landscaping verandas, arches and gazebos.
By the middle of summer, green lianas are covered with large and showy flowers, and the period of decorativeness in most varieties lasts until the first frost. All these characteristics attracted me when I was looking for the right plant to decorate my porch.
Like any ornamental plant, the splendor of flowering in clematis depends on a comfortable degree of illumination, sufficient watering and timely fertilization.
In order for the planted vines to grow better and delight my eyes with large and abundant inflorescences, even before planting, I was concerned about what kind of feeding they would like.
Clematis vines can stretch up to 4 meters in one season. To provide the plant with sufficient strength for such active growth and the accompanying abundant flowering, it is necessary, even during planting, to ensure that there is a sufficient amount of organic and mineral fertilizers in the planting pit.
Of course, clematis will not bloom in the first year - all the forces of the plant will be directed to rooting and growth. But already now the vine needs sufficient nutrition, the deficiency of important microelements will lead to a delay in the development of sprouts. To avoid this, it is necessary to replenish the soil before planting clematis in the planting pit.
For this, the planting pit is filled with humus or compost mixed with wood ash. This nutrition will be enough for the sprout for the whole year. This composition will contain enough organic and mineral elements for the rooting of the vine, its adaptation, growth and proper preparation for wintering.
Fertilizers for adult clematis
The introduction of both organic and mineral fertilizers for clematis should be strictly verified and follow a clear schedule. They alternate, observing certain proportions, correlating feeding with the periods of growth of the vine.
Top dressing in spring
In the second year after planting, starting in spring, you can start applying organic fertilizers for clematis. During the awakening of the plant, young shoots are actively formed, and flower stalks are also laid. The more organic fertilizers there are in the spring, the more actively the liana will grow and the more luxuriant the inflorescences will be.
For the first feeding, which is done before the start of sap flow, one of the following compositions is used:
- manure solution (1:10 with water);
- solution of poultry droppings (1:10 with water);
- urea solution (at the rate of 20 g / m 2).
With these solutions, the area where clematis is planted is spilled, at the rate of 10 liters per 1 m 2. 2 weeks after organic top dressing, the soil must be fertilized with wood ash, sprinkling it on moist soil (0.5 cups per 1 shoot).
This affordable fertilizer, which is available on every site after spring harvesting and pruning, contains a whole range of useful mineral elements that are important for the development of clematis and its abundant flowering.
This is not the end of the spring feeding of clematis: in mid-late April, when the plant awakens, it is necessary to re-apply nitrogen-containing fertilizers. After that, it will be useful to spray the stems in the evening with a urea solution: nitrogen penetrates not only through the root system, but also through the pores on the shoots.
Additional enrichment of clematis with nitrogen at this stage will allow it to grow actively, performing its decorative function.
The alternation of organic and mineral dressings ends in May. Now it is necessary to slightly reduce the acidity of the soil, which manifests itself after repeated use of nitrogen-containing fertilizers.
For this, lime milk is used (150 grams of slaked lime is dissolved in 10 liters of water). This volume is quite enough to slightly balance the PH to values that are comfortable for the plant.
Summer feeding
The formation of buds in early summer signals that it is time to change tactics. Now clematis needs additional fertilizing, rich in phosphorus and potassium.
In order for the plant to be fully provided with important elements, it is best to use mineral complexes without chlorine, created specifically for ornamental flowers and shrubs.
If you are not an adherent of "chemicals", in June you can help clematis to fill the deficiency of elements, using a tincture of cow dung. The overripe mass is diluted in water in a ratio of 1:10 and infused for a day in a container under a lid.
Then the soil is poured abundantly around the stems with a solution, while it is important not to direct the stream or the watering can divider directly under the root, so as not to burn it.
In the summer, in June-July, clematis will really like the healing and nourishing spraying with solutions of boric acid and potassium permanganate.
A weak solution of potassium permanganate will help eliminate pathogenic microflora and fungi that can harm the plant, and boron, penetrating through the pores in the stems, will strengthen local immunity.
From the beginning of August, nitrogen must be completely removed from the dressings. Now it is necessary to stop the growth of the plant and help it prepare for wintering. For this, mineral complexes containing potassium and phosphorus are used, for example, potassium sulfate. 30 grams of powder is diluted in 10 liters. water and spill the soil around clematis with a ready-made solution.
In summer, at the end of August, clematis need potassium and phosphorus. It is best to use potassium sulfate, which is diluted in water and fed to the vine. For ten liters of water, thirty grams of the substance are needed.
Learn more about the fertilizing that clematis needs in spring and summer for normal growth and abundant flowering, you will learn from the video:
When organizing feedings for clematis, consider the following important recommendations:
- Before making any top dressing, the soil around the clematis must be shed abundantly, so that the fertilizer will quickly get to the roots and will not spread along the ground.
- When making foliar dressing and preventive spraying, treat the plant and leaves on both sides.
- Spray the plants in the evening - this will keep moisture on the foliage and stems longer and bring more benefits to clematis.
- In order for clematis to bloom more abundantly and longer, after the appearance of the first inflorescences, feeding stops.
- Clematis roots love moisture and do not tolerate overheating. To create a comfortable environment for the plant, plant undersized flowers or a lawn near the stems that protect the soil from the sun's rays, and ensure timely watering.
- Despite being hygrophilous, clematis will feel bad in prolonged rains. To prevent root decay, generously sprinkle the soil around the vines with ash during heavy rainfall.
Provide clematis with enough nutrition and it will reward you by creating a striking green hedge adorned with lush flowers with its vines.
When applying top dressing, remember to be in moderation, since a surplus of certain elements can harm the plant.
Before fertilizing clematis in the spring to activate growth after a long winter, be sure to check for pests and signs of fungal infection on the plant. Feeding clematis in early spring with milk of lime is an effective means of protecting against diseases and pests. We recommend using it first.
Luxurious clematis is a flower desired by many gardeners. There are about 300 varieties of garden creeping vines known in the world. They are used to decorate gardens and buildings. Under the wrong conditions, the perennial withers and may stop blooming. Often this is due to the fact that the grower does not know how to properly fertilize clematis for lush flowering at different times of the year. This is what we will talk about in today's article and we will understand this issue in as much detail as possible.
Look at the photo of plants that are properly cared for in spring, summer and autumn - they delight the eye with lush and long flowering:
The first thing to fertilize clematis in the spring is nitrogen, this element will give an instant increase in green mass
The second top dressing of clematis in early spring is potassium and phosphorus, they give a lush and long flowering
If you organize optimal conditions for clematis and feed him, according to all the recommendations, then he can safely live in one place for about 25-30 years. The plant is not demanding for transplants, if it is satisfied with the composition of the soil. After planting, they begin to feed the perennial after about two years. But, this is only on condition that the planting pit has been properly prepared and filled with nutrients. Make sure that clematis cannot be deeply buried in the ground, this can cause the perennial to stop blooming. But, most often it happens that inept florists, when planting a plant, leave the root collar above the ground. Often this happens by itself, for example, during watering. Keep track of this and, if possible and necessary, huddle the plants. 
Most varieties of clematis prefer slightly acidic soil. Therefore, it is important to use fertilizers that reduce the alkaline reaction. Soil deoxidation is carried out in the spring. This is done more often using lime. Before planting clematis and other plants, the site is dug up with the addition of limestone. A more expensive option is to use dolomite flour. But it is known to have established itself as a more effective remedy for spring deoxidation. If you do not know how to feed clematis in early spring for growth after winter, then add dolomite flour in the amount of 100 - 150 gr. for 1 sq. m area for loosening. This will be the best agricultural technique, guaranteeing rapid growth of green mass and a set of buds for the whole summer. 
To "kill two birds with one stone" - to deoxidize the soil and make it looser when digging a site, add ash. It makes the soil lighter and more breathable. Florists use this method in spring and in small areas. If the area is large, then there may not be enough ash. Therefore, a more rational solution for large gardens is lime. 
Do you know what kind of top dressing clematis like at the beginning of the growing season? This is the following diagram:
- after the snow melts, the introduction of wood ash or dolomite flour directly into the soil;
- after 3 days, abundant spraying of all shoots with a solution of succinic acid (5 tablets per 2 liters of water);
- after 5 days - application of root liquid top dressing containing nitrogen, potassium and phosphorus;
- after another week, the introduction of liquid root dressing based on humic acids. Then fertilizers are applied once a week with alternating organic matter and mineral complexes.
Spring feeding of clematis for abundant flowering
How abundant and lush the clematis blooms in summer depends on spring feeding. At this time of the year, the plant requires increased attention. We recommend carrying out fertilization and care procedures for perennials at least once a week. The most important step in the spring is pruning. It is carried out after the snow melts. The weakest and driest vines are selected and removed with garden shears. In adult plants that grow on the site for more than 10 years, the rhizome zone is examined. Please note that clematis do not grow in breadth, but they may have a bare root collar. 
In spring, clematis needs a lot of nitrogen. Therefore, they try to feed the plant with nitrogen compounds. The first feeding of clematis in the spring for abundant flowering is mainly carried out with organic complexes. For root fertilization, bird droppings (no more than a liter) or slurry diluted in 10 liters of water are used. Spring organic fertilizers are applied immediately after the snow melts. They need to be stopped at the moment when clematis begins to lay buds. Usually, this happens closer to summer.
You can safely use urea at the rate of 20 grams per 1 sq. meter. It is also diluted in warm water. There should be no more than 5 liters of such a solution per bush. When the abundant development of green mass begins, it is important not to miss the moment when foliar feeding is important. For spring feeding of clematis, urea is used, diluted in an amount of 3 grams per liter of water. Spray vines and leaf plates from the back. This is best done after sunset or in cloudy weather. If the sun's rays hit the leaves and shoots, this will lead to the decomposition of beneficial nutrients and the fertilizer simply will not work. 
May is the time when soil protection from acidification is required. You can use one of the methods described above. But, it is best to take 150 grams of slaked lime for 10 liters of water. The solution is poured under the root. It is best to carry out the procedure several times in May. 
At the end of spring, in the last days of May, fertilizing begins to increase immunity and stimulate the formation of buds. Fertilizers containing potassium and phosphorus will help with this. You can use superphosphate and potassium sulfate in an amount of no more than 20 grams each per 10 liters. clean water.
For a luxurious summer bloom
We have considered how to feed clematis in the spring, now let's move on to the following months. June, July, August and September is the period when the vine is picking up buds and blooming. In summer, clematis bloom profusely and for a long time. In order for a plant to withstand such a marathon, it is necessary to organize periodic feeding for it. Fertilizers should replenish nutrients, but not make the soil heavier, much less make it sour. When choosing a mineral complex, pay attention that the composition does not contain chlorine. It is contraindicated for feeding clematis. Under its influence, the root system is inhibited and the plant's immunity is weakened. You can look above how to feed clematis in the spring for a lush bloom and use this scheme for application in the summer months. 
To maintain abundant flowering, top dressing is applied before the perennial begins to bloom. This is done using organic and mineral compounds. Don't be afraid to use nitrogen-rich fertilizers. During the period when clematis lays the buds, it is also needed. The immunity of the perennial and its root system can be maintained in several ways. First of all, you need to make nutritional formulations with a high potassium content. For example, ammophoska or nitrophoska is suitable. Also, to maintain health, before fertilizing clematis in the spring after winter for lush flowering, you can spray or water them with a solution of potassium permanganate.
Phosphorus during bud swelling is very important. It is this element that is responsible for active flowering. It is best used in combination with other minerals. As for organics, here the most successful compositions are weed tincture or fermented manure. They are often used to dilute nitrophosphate.
When clematis begins to bloom, its feeding is reduced or stopped altogether. Without fertilization, flowering is prolonged and becomes more abundant. The end of budding is in August. It is at this time that the last flowers fall and the plant begins to prepare for a dormant period. At this time, nitrogen fertilizers cannot be used, which will provoke the development of the green part. Shoots and leaves simply do not have time to ripen and the perennial will be more vulnerable to cold weather. Here it is better to focus on fertilizers containing potassium and phosphorus. 
Many flower growers ask whether it is possible to feed clematis with succinic acid and what such an agricultural technique gives. Succinic acid is a vine growth stimulant and an excellent means for maintaining a high level of immunity. Therefore, it is advisable to spray the vegetative mass twice a year: in early spring to accelerate the growth process and in autumn to prepare for a successful wintering. 
Autumn feeding and preparation for wintering
In the fall, feeding is stopped. The most important procedure is mulching with perennial ash, namely the base of its bush. About 0.5 kg of ash is enough for one plant. It is laid under the bush and compacted well. Autumn fertilization ends there. Next, they carry out the procedures necessary to prepare clematis for the wintering period. In the cold regions of our country, all varieties need a warm shelter for this time of year.
In warm regions, the plant also needs shelter. Before proceeding with its construction, the bush is cut off. Put the box on top, bottom up. Such a shelter must be hidden from severe frosts. This is done with dry leaves, spruce branches and other plants. If clematis is designed like a creeping or climbing liana, then it should not be removed from the support. It is best to initially ensure that the support is removable or can be laid on the ground if necessary. This will greatly facilitate not only care, but also the preparation of the plant for winter.
Now you know how to fertilize clematis in spring, summer and autumn in order to get a lush and longer flowering of this luxurious vine on your site.
