When clematis does not bloom, it is a big disappointment for the gardener. After all, adult bushes are able to smell good from spring to fall. There are many reasons why clematis does not bloom. It all depends on the variety, planting site, culture. The absence of flowering is manifested by the influence of one or several factors at once. During the first year of life, the plant does not bloom. With well-organized care, buds appear only for 3-4 years.

When does clematis bloom?

After planting, the first time the seedling builds the root system and strengthens in a new place. After the above period, clematis begins to lay flower buds. Flowering itself is determined by varietal affiliation.

  1. Climbing plants that bloom in May-June: Miss Bateman, Barbara Jackman, Pilou, Grapevine. Usually the process is repeated in September.
  2. Varieties that open in July: Rouge Cardina, Biz Jubilee.
  3. Flowering clematis in September-October: Pilou, Gypsy Queen.
  4. Varieties that bloom all summer: Nikolai Rubtsov, Ville de Lyon, Hot White, Multi Blue.

Clematis of the first pruning group form buds in the summer and autumn of the current year and bloom in April-May of the next. Therefore, their whips are not cut off. In plants of the second group, buds bloom in June-July, shoots of past and current years take part. The third group blooms from mid-summer to fall. Plant buds on young vines.

Reasons for lack of flowering

Before embarking on drastic measures, it is worth understanding the reasons for the lack of flowering. There are a lot of them, but even an inexperienced grower is able to handle and manage them.

Important! Timely care will help the plant to recover and bloom.

Violation of rules of care

The wrong place to plant is a common reason why clematis does not bloom. For full development and active growth, the vine needs morning and evening sun, midday – partial shade. The plant is afraid of drafts and winds. From strong gusts, fragile shoots can break and merge, their petals fly off.

During the site selection process, particular attention should be paid to the soil. It is advisable to plant clematis in well-drained soil with a neutral or slightly alkaline reaction. The soil should be loose, light, nutritious.

Advice! If the soil is acidic, lime or dolomite flour must first be added.

The roots of flowering vines go deep into the ground, so the groundwater level in the area must be low. It is not recommended to plant clematis in pots with a volume of less than 50 liters. The soil should be loosened regularly. The root system needs air to grow.

Also, clematis does not bloom if it is overgrown with weeds. Grass and cultivated perennials growing nearby take up some of the nutrients from the soil. This, therefore, negatively affects flowering. Therefore, there should be a free space of vegetation around the clematis.

Nutrient deficiency

Clematis is a perennial plant that can grow in one area for 10-40 years without a transplant. Over time, the flowers become smaller, the number of buds decreases, and the fragrance period becomes shorter. Detailed symptoms speak of old age. However, very young vines can also stop flowering if soil nutrients are completely lacking.

It is important for a gardener to know that from the second year of life, clematis requires systematic feeding. In early spring, nitrogen-containing components are used to improve growth. This stimulates the appearance of leaves and new shoots. The vegetative part helps the bush to accumulate energy and strength for the subsequent appearance of inflorescences.

During the period of budding and flowering itself, the plant requires full care. For this, phosphate fertilizers are chosen, thanks to which large bright flowers are formed. The petals do not fall off for a long time. When using a foliar dressing, the foliage should be sprayed from both sides.

Closer to autumn, clematis is fed with organic solutions. Thus, it will be able to feed abundantly and withstand the winter more easily.

Important! With timely and regular dressing, pruning can delay the aging process. When all else fails, it’s time to repot the clematis.

pest attack

If clematis does not bloom, this is a clear violation of the normal state of the plant. The bush can be attacked by harmful insects. For example, nematodes appear on the root system, violate its integrity. Bed bugs, aphids, slugs impoverish the bush. Medvedka eats roots, and rodents also eat the green part of the vine.

Pest control should be carried out constantly and not wait for flowering.

  • Aphids, bedbugs, worms are eliminated by means of insecticides or tobacco dust.
  • Nematodes are removed from the bush using nematocides, which are applied to the soil 30 days before planting the seedling.
  • Slugs are easy to pick up by hand or cultivate the ground under a bush with a 1% copper solution.
  • Rodents are captured using bait or traps containing zoocides.

The bush stops flowering when it is fighting an infection. Clematis suffers from such diseases: fusarium, gray rot, rust, leaf spot, yellow mosaic. Systemic fungicides will help cope with ailments, as well as sprinkling the soil with a mixture of wood ash and sand in the proportions of 1:10.

Other reasons

Clematis will not be able to bloom if it has not wintered well. The vines are covered at the end of autumn, when the outside temperature drops to -3°C. Only cold-resistant varieties can do without shelter in central Russia. Even if the vines have been saved, the flower buds may be damaged. If you do not want clematis to bloom with single inflorescences, you need to take care of a high-quality shelter for the winter.

How to make a clematis flower

Before buying and planting a plant, you need to know the exact name of the variety. Because the choice of a place and the implementation of the basic cultural activities depend on the variety of the vines in flower. When choosing a species, special attention should be paid to the size group of clematis. This is an important point on which the flowering of clematis depends.

Vinaigrette

Long and abundant flowering leads to the absorption of a large amount of nutrients from the soil. Clematis requires an alternation of mineral and organic elements. For even consumption of fertilizer, it is recommended to feed the bush 4 times per season.

  1. Weak mullein solution: 1 cl for 10 liters of water. A bucket of this liquid is poured under each plant. The period of the procedure is from April to May, when the first shoots sprout.
  2. After 2 weeks, the second stage takes place. Ammonium nitrate is added to the organic suspension at the rate of 1 tbsp. to a bucket of water.
  3. As soon as the clematis bloom, they switch to potassium-phosphorus top dressing. For 10 liters of water you need 25 g of potassium nitrate, and in mid-August – 25 g of potassium sulfate.
  4. The source of phosphorus is bone meal. It is introduced into the soil with the onset of autumn 200 g per 1 m². Mr.

Important! Without top dressing, you cannot get clematis, which blooms attractively.

Stimulants

Curly flower responds well to synthetic components. Stimulants are used to achieve a more saturated color of the petals, larger buds and lush flowering. Experienced gardeners advise the use of humates, preparations “Buton”, “Epin”, “Zircon”. Processing is carried out if necessary at the time of the opening of the inflorescences.

cut

The procedure is of great importance: if it is carried out incorrectly, the clematis will not bloom at all or will, but rather weakly. To prune correctly, you need to know which group the flower belongs to. There are only three:

  • first – varieties that flower only on the vines of the previous year;
  • second – plants that bloom on the shoots of this season and last;
  • third – the clematis that bloom on the branches of the current year.

According to the group, the branch deletion procedure is carried out. It is the last type that is completely cut. Leave a height of only 10-15 cm from the ground or 2-3 buds. In late autumn, the bush is covered with sawdust, peat, dry leaves for better wintering. It is best to make a 30-40 cm layer of mulch and cover it with roofing material or agrofiber from above.

Similarly, a vine from the first group will not flower if the vines are not pruned properly. Before the onset of frost, they try to remove underdeveloped shoots, shorten young branches, leaving no more than 1.5 m in length. Active growth of this species involves regular adjustment of the shape of the bush. Lianas flower in July.

The second group is cut twice a season. For the first time after the end of flowering, the flowering part is removed from the old vines. In mid-autumn, dry shoots and weak shoots are pruned, reducing the thickening of the bush. The remaining branches are cut from 1 to 1.5 m. You can lengthen one part of the vines and shorten the other. This will form a lush bush.

watering

Engorgement with these colors is contraindicated. It is necessary to moisturize once a week, in case of dryness – once every 5 days. This volume will be optimal during the first 2-3 years. An adult bush should be watered once every 10 days, with a water volume of 30-40 liters. The soil should be wetted to a depth of 50-70 cm. To prevent the root system from rotting due to frequent rains, it is necessary to sprinkle wood ash around the plant.

Advice! It is recommended to pour water not in the center of the bush, but in a furrow dug at a distance of 30 cm from it.

Conclusion

Clematis does not bloom for various reasons, but there is no need to rush to get rid of the plant. The first step is to identify the negative factors that affect the condition of the bush. Secondly, it is important to know the age, perhaps it is too early to bloom or, on the contrary, clematis needs rejuvenation. Third, you need to set the grade and crop group.
