Colquitia


The flowering plant Kolkwitzia belongs to the monotypic genus of the subfamily Linnaeus of the honeysuckle family. This genus is represented by only one species - pleasant or lovely (Kolkwitzia amabilis), which is a shrub. In nature, such a plant can be found in the mountainous regions of Central China, as well as in other regions with a temperate climate. This shrub was named after the German botanist R. Kolkwitz. It was brought to European countries in 1901, while the first flowering of such a plant in unusual conditions for it was noted only in 1910.

Features of kolkvitsiya

Kolkvitsiya is a deciduous shrub that reaches a height of 2-3.5 meters. On the surface of young stems there is pubescence, consisting of short hairs, while the old shoots are covered with a brown-red bark, it exfoliates with plates, which is typical for all representatives of the honeysuckle family. If conditions are favorable for kolkvitsiya, then it develops a dense root growth. Opposite paired leaf plates of oval shape and deep green color in length can reach 3.5-8 centimeters. In autumn, the foliage turns yellow. Five-lobed graceful bell-shaped flowers have a light yellow color on the inner surface and pink on the outside. The unusually lush bloom lasts about half a month in spring and summer. There are so many flowers that it is impossible to see the foliage because of them. Bristly fruits are dry.

Planting kolkvitsii in open ground

What time to plant

For planting kolkvitsiya, you should choose spring time, while the soil should warm up well. The planting site should be sunny and protected from strong gusts of wind, if you wish, you can grow colquia in a little shade. Remember that areas that are covered with melt water for a long time in spring are not suitable for planting this shrub. The substrate should be nutritious, light, neutral and well-drained.

Landing features

The landing pit should be prepared half a month before the scheduled landing day. In depth, it should be about 0.4 m, while its length and width can vary from 0.5 to 0.6 m.Then the pit should be covered with soil mixture, which should include sand, turf and humus (1: 2 : 2). For half a month, such a mixture will thoroughly condense and settle.

It is best to choose seedlings for planting that are 1 or 2 years old. Immediately before planting the plant in open soil, it will be necessary to shorten the overly long roots. Then the seedling is placed in a prepared pit, which is filled with the same earth mixture, but one more bucket of wood ash or from 80 to 130 grams of complex mineral fertilizer must be poured into it. Remember to compact the soil well. The planted plant needs abundant watering. After the liquid is completely absorbed into the ground, the surface of the trunk circle must be covered with a layer of mulch.

Caring for colquia in the garden

When growing kolkvitsiya, it is important to take into account that the soil in the near-trunk circle should not dry out in any case. For irrigation, use settled water, which should not be cold.

In order for the shrub to develop and grow normally, it must be fed in a timely manner. In spring, for this purpose, an infusion of mullein is used (1:10), while in the first summer weeks a solution of double superphosphate is added (for 10 liters of water from 30 to 50 grams of substance). Take 10 liters of nutrient mixture for 1 bush.

After the end of flowering, it is no longer possible to feed the plant, but formative pruning will need to be done. At the very end of the season, it is necessary to remove all young shoots that did not have time to ripen by the beginning of the winter period. In the spring, you need to make sanitary pruning, for this you should cut out all injured, dried out branches and stems damaged by frost, pests or disease, as well as those that thicken the bush. Throughout the summer period, it will be necessary to timely remove the root growth, which grows extremely intensively in favorable conditions for colquation.

Transfer

Such a shrub tolerates transplantation very well. To do this, the bush must be carefully dug out, trying not to injure its root system, and then it is carefully transferred to the prepared planting hole, which should be covered with a soil mixture saturated with nutrients. The transplanted bush needs abundant watering. After the liquid is completely absorbed into the soil, the surface of the trunk circle will need to be covered with a layer of mulch.

Reproduction of colquitsia

Such a plant can be propagated by seed (generative) method, as well as vegetative - by layering, cuttings and dividing the bush.

Seed method

Cultivation of colquitia from seeds takes quite a long time and does not always end successfully. For stratification, the seeds are placed in a refrigerator on a vegetable shelf for 3 months. They are sown in April, using a long container filled with soil mixture, which includes peat, garden soil and sand. The container must be covered with foil and transferred to a warm place. The seedlings will have to be grown indoors until the next spring.

Dividing the bush

You can propagate the shrub by dividing the bush during transplantation. A thorough examination of the roots of a dug plant should be carried out, while dried and rotten roots should be removed. Then the bush is cut into several parts, while it should be borne in mind that each delenka must have powerful stems and developed roots. Places of cuts must be sprinkled with crushed coal. It is necessary to plant such delenki in prepared pits. This procedure is carried out in the same order as the initial landing.

Layers

Rooting cuttings is the most effective propagation method. The selected coppice shoot must be bent to the soil surface and placed in the prepared groove. In the place where the shoot comes into contact with the soil, an incision must be made and treated with a growth stimulating agent. The shoot is fixed in this position and covered with soil, while its upper part should remain free. During the summer period, do not forget to water the cuttings in a timely manner so that the soil around it is always slightly damp. After a short time, roots will grow from the buds that are underground. It will be possible to separate such a layer and plant it in a new place only next spring.

Reproduction of colquitia by cuttings

Reproduction by cuttings is carried out in spring and autumn. So, in May, you should cut off semi-lignified cuttings, which are planted in a tub filled with soil mixture for seedlings. For the winter, this container, if desired, is removed to the basement. Cuttings harvested in the fall take root better. To do this, cuttings cut in autumn must be wrapped in polyethylene and removed to the basement, in spring they are treated with Kornevin and planted in a greenhouse, where they will stay until the next spring period. For planting in open soil, such a seedling must be taken together with an earthen clod. After 1 or 2 years after planting in a permanent place, these shrubs will begin to bloom.

Diseases and pests

Such a plant is resistant to diseases and pests, but if the weather is hot, then spider mites, aphids or thrips can settle on the bush. In order to get rid of these pests that suck the juice from the plant, use a solution of acaricide (Aktara or Aktellik), 2 or 3 treatments will be needed, while the duration of the break between them is 7 days. Caterpillars eating its leaves can also settle on the kolkvitsiya. With a small number of them, manual collection should be made. If there are a lot of caterpillars, then spray the bush with an insecticide.

After flowering

If, according to forecasters, the next winter will be with little snow and very cold, it is imperative to cover the colquation. After the air temperature is set at a minus mark, it will be necessary to cover the near-trunk circle the size of the crown projection with a layer of peat, wood chips or bark, the thickness of which should be from 10 to 12 centimeters. If the shrub is not yet 5 years old, then it is bent to the soil, covered with spruce branches, and in winter time a layer of snow is thrown over it. If desired, the crown of the plant is wrapped in spunbond or lutrasil, it is removed only in the second half of April, after the air temperature is above zero degrees. If the winter turns out to be extremely frosty, then the colquitation may freeze, but in spring it recovers extremely quickly. At the same time, experienced gardeners note that the older the plant, the higher its frost resistance.

Growing in the suburbs

If kolkvitsiya is grown in regions with a cold climate, then its young shoots do not always have time to ripen before winter, and therefore, in the springtime, dry tips can often be seen on the bush. They should be cut before the plant blooms. In order for the shoots to ripen faster, when the bush fades, it is necessary to reduce watering, stop applying fertilizing, and also cover the near-trunk circle with a layer of mulch (peat or compost combined with sawdust or foliage), the thickness of which should be from 5 to 10 centimeters. This will not only protect the roots of the plant from winter frosts, but also force it to accumulate nutrients. In late autumn, you need to cut off almost all young growths. In this case, lignified stems with a small number of young growths should remain on the bush.

Types and varieties with photos

There are only 2 varieties of lovely colquia, namely:

  1. Rosea... The color of the flowers is bright pink.
  2. Pink Cloud... The color of the flowers is deep pink.

Recommendations for planting and caring for colquia in the open field

  1. Landing place flowering shrub must be selected in accordance with the natural preferences of the plant. So the location should be open and well-lit by the sun's rays, but partial shade may come up, but then the abundance of flowering will suffer a little. Such a place for a charming colquition can be a neighborhood with large trees, under their openwork crown. It is also worth making sure that the growing area is protected from strong gusts of wind during the winter. Although kolkvitsiya pleasant differs in rather high rates of winter hardiness, but when the column of the thermometer drops to -30 frost, its young branches can freeze slightly. You should not plant in a place where groundwater is close or moisture tends to accumulate from precipitation or melting snow.
  2. Soil for kolkvitsiya charming should be light, fertile and well-drained with moderate moisture. It is recommended that the acidity values ​​are neutral (pH 6.5-7), but the plant can accept an alkaline substrate (pH 7-8).
  3. Planting kolkvitsiya pleasant is carried out in the spring, when the soil will already be fully warmed up - in about April. The depth of the hole for planting seedlings is dug up to about 0.5 m, with the same diameter. A composition of humus and river sand fits into it, or it can be replaced with a soil mixture from a sod substrate, river sand and humus, in a ratio of 2: 1: 2, respectively. After that, you need to leave the hole for 14 days so that the soil in it settles and compresses a little. The intensification of the growth of the planted saplings of the charming colquia will begin in the summer, and the subsequent flowering can be expected only next year. For planting, it is best to pick up 1-2 year old plants. Before planting them, it is recommended to remove too long root processes from them. Then the seedlings of kolkvitsiya are installed in the planting hole and the voids are filled with the above-mentioned soil mixture, but with the addition of a bucket of wood ash or complex mineral fertilizers (80-130 grams) to it. After planting the colquicia plant, the lovely soil around it is gently squeezed and abundant moisture is carried out. When the moisture is completely absorbed into the soil, then the trunk circle should be mulched using peat or sawdust. Such a layer will not only help the substrate to remain moist for a longer time, but also prevent weeds from growing rapidly. For group planting, the distance between seedlings should not be less than 1.5–2 m.
  4. Pruning when caring for a colquation, a pleasant one is an obligatory procedure. So with the arrival of spring, while the buds have not yet begun to bloom, sanitary cleaning of the bush crown should be carried out, cutting out all frozen shoots. At the same time, you need to remove all old and diseased shoots. After the flowering is completed, you can perform the formation of the crown - cut off the branches that are too thickening and growing inward or too extended beyond the intended outlines of the bush. Root shoots of colquation must be removed as they grow in any growing season. After flowering is completed, the faded branches should be shortened, and at the end of the growing season it is recommended to cut off all young branches that have not yet matured.
  5. Watering. When caring for kolquicia, it is recommended that the soil under the bush always remains slightly moistened, but it is important not to bring it to acidification, so as not to provoke the occurrence of fungal diseases. It is better to use settled and cold water. The soil should be moistened in the evening.
  6. Fertilizers when growing a flowering shrub, it is required to be carried out regularly throughout the growing season. In the spring months, it is necessary to use organic matter (for example, mullein diluted in water in a ratio of 1:10). In June, top dressing is applied with double superphosphate, dissolving 35–45 grams of the drug in 10 liters. There should be one bucket for each bush of colquitia of such a lovely solution. After flowering is complete, the plant should not be fertilized so as not to provoke its growth by the winter months.
  7. Colquitia transplant carried out in the case when it is necessary to change the place of cultivation. The plant copes with this procedure with ease. It is important to carefully dig up the bush. It is bayonetted around the perimeter with a pointed shovel and removed from the soil with a garden pitchfork. At the same time, they try not to damage the root system of the plant. The transplant is carried out immediately into a pit prepared in advance according to the previously described requirements, in which a nutritious soil mixture is laid. Then it is necessary to carry out abundant watering and, after absorbing moisture, the near-stem soil is mulched.
  8. General advice on care. When growing a pleasant colquitia, it is recommended at the end of May to mulch the circle corresponding to the projection of the crown of the bush and exceed it by 15 cm. The thickness of the mulch layer is approximately 10 cm. Wood chips, crushed bark or peat chips are used as mulch. When autumn comes and the temperature is already steadily in the negative range of the thermometer, mulching is carried out again. As the flowers wither, you need to deal with their removal.
  9. Colquitia is pleasant after flowering. To help the early ripening of the shoots, when the flowering process is completed, the soil moisture is greatly reduced, and the plant is no longer fed. The soil is mulched.However, if by winter the shoots at the ends of the branches still have not reached maturity, they are cut off. The plant is winter-hardy, which in itself serves as protection from frost, but it is recommended to help the shrub a little to survive the cold season. So the near-trunk circle should be mulched with peat or wood chips in such a way that the mulch layer reaches 10-12 cm. The mulching diameter should correspond to the projection of the kolkvitia crown. If the plant has not grown to the age of five, then its branches can be bent neatly to the surface of the soil and covered with spruce branches, and with the arrival of winter, a snow layer can be put on top. But in snowless winters, you should use a non-woven material, covering the crown with spunbond or other agrofibre. Only with the arrival of mid-April can such a shelter be removed from the pleasant colquation - only if the average daily temperature exceeds zero. If the winter period turned out to be very frosty, then the young shoots of the shrub may be exposed to freezing, however, there is no need to worry, since with the arrival of spring they will quickly recover. It is noted that as they grow older, the winter hardiness of the colquitia bush will only increase.
  10. Application of kolkvitsiya in landscape design. This shrub will be a real decoration in cool and temperate climates. However, due to the fact that after flowering, which occurs in the first half of summer, and then decorativeness decreases, the plant should be planted nearby with representatives of the garden flora, looking spectacular throughout the season. But if a pleasant colquation is planted as a tapeworm, then it is recommended to place it against the background of a carefully groomed lawn area. Such a shrub will be a wonderful decoration against the background of a terrace or structures of a reddish-brown color. The best neighbors for a lovely colquition will be plantings of irises or peonies. When planting other perennial plants with the same growth form, for example, deytion or weigela, next to this flowering shrub, it will be possible to form a hedge. A good combination next to it will be a bluish background, which gives blue Himalayan blue geranium or Narbon linen. At the foot of the Kolkwitzia bush, ground cover crops can be planted, such as chickweed with a silvery-white leaf color, dwarf barberries, which give a brick-red hue of the cover. If we talk about such a colorful combination as purple and pinkish shades, then Robinia looks great next to the colquation. From low shrub crops, Japanese spirea or holly manogia is planted nearby.


Application in the garden

Weigela can reach a height of 2-3 meters. Some varieties are smaller. They are planted in the garden as follows:

  1. Alone on the lawn or in the garden. Looks beautiful on a bright green lawn, against a light wall or wooden fence.
  2. For hedges. The shrubs do not have a very compact crown and are often used for hedges that serve as a decorative border between plots rather than an actual separation. Weigels are good in the role of a hedge, long, jagged leaves, intensely colored in green with an attractive shine, give them decorativeness. They also hang slightly on thin branches.
  3. Low varieties can be planted in pots, containers.
  4. Dwarf varieties can be used to create green strokes.

If the weigela is not planted as a hedge or a potted plant, forsythia, jasmine, and colquitia will be a good company for her.

Tall perennials, such as astilbe, are also suitable. It is only important to maintain sufficient spacing between growing bushes and perennials.

Weigela looks beautiful in autumn.

Weigela is a wonderful shrub that does not need special care. Its cultivation is within the power of even novice gardeners. A little attention and a little care will allow the plant to delight with beautiful flowers year after year.
