Easter rose planting and care. Kerria Japanese will decorate any garden. Varieties of varieties of Japanese kerria

An elegant and unique shrub, with bright yellow flowers resembling medium-sized roses or pretty pompoms - Japanese kerria will be a great addition to the flower garden country house or cottages. Its place of origin is considered to be the forests and mountainous areas of Japan, as well as the southwestern part of China.

Description

Japanese Kerria is a deciduous shrub, vertically growing, reaching a height and width of up to 1.5 - 2 m. It belongs to the Rosaceae family. It blooms with yellow single flowers, 3.5 to 6 cm in diameter, located in the axils of the leaves. Flowers are formed both on old branches and on young shoots. The flowering time of the shrub is April-May, and a period of repeated, but not so abundant flowering at the end of summer is also possible. The gentle sweetish aroma of flowers is similar to the smell of flowering dandelions.

The leaves of Kerria are green, ovoid, serrated at the edges, up to 10 cm in length. Actively growing, the shrub sprouts rod-shaped shoots, forming dense thickets, they look spectacular in the winter garden, especially against the snow-white background of the fallen snow. The root system of the shrub, actively growing, forms a dense shoot.

Varieties of varieties of Japanese kerria

The shrub genus contains only one species - Japanese kerria, which has several varieties. The most common garden varieties are presented below, in the photo of which characteristic features are visible:

The Kerriya Japanese Pleniflora variety is the most widespread, for the special sophistication and velvety of the terry flower petals, as well as the beauty of the carved leaves.

Features of planting and caring for Japanese kerria

The condition for the successful cultivation of kerria is proper fit, as well as compliance with the rules of care.

Landing

Kerria is planted in a hole 60 * 60 cm wide and 45 - 50 cm deep. Favorable for the survival of the bush and its further growth is the ratio of the components of the mixture for planting 3:3:2, which includes humus, soddy soil and fertile garden soil. About 80 g of mineral fertilizers are also added to the resulting mixture. It is best to transplant it in spring or autumn, when there are no leaves.

A place for landing is chosen calm, sufficiently illuminated by the sun. Kerria grows well in partial shade, but then its flowering is less intense. The shrub prefers sufficient watering, so it requires weekly abundant moisture, and after transplanting it is watered even more often, and requires impregnation of the root zone with water and mulching.

Important! Bushes grow quickly and strongly in breadth, so they can take up a lot of space, which should be taken into account when planting.

Care

The shrub, although quite moisture-loving, nevertheless, does not tolerate excessive moisture. It must be watered regularly during the flowering period and during extreme heat, while avoiding stagnation of moisture in the soil. Once a week, it is necessary to include mineral supplements in the water for irrigation in the form of special preparations for ornamental and flowering crops.

Important! Top dressing is carried out only in kerria older than two years, since the roots of a young shrub are too tender and can get burned from fertilizers

One of the important components of care is regular pruning. It is held in the spring, after the end of frost. Frozen, broken and dry branches are cut off, and for greater stimulation for branching, good shoots are shortened by a third. After the flowering period, pruning is also carried out - the shoots on which there was no flowering are removed, and those on which there were no flowers are left, it is on them that they will appear in the fall. In the same period, it is worth pruning all branches older than 4-5 years. Too overgrown kerria is periodically thinned out.

Since the shrub may suffer from frost, it is recommended to cover it for the winter, with the onset of cold weather (from mid-October). The procedure for preparing for winter is carried out in dry weather: the bushes, bent to the ground, are laid on a dry substrate made of foam or other material and fixed with a frame made of stakes. This provides reliable protection branches from damage. Then dry leaves or shavings are poured, and two layers of lutrasil are laid on top. The resulting protective structure should be well ventilated and dry, without letting the plant rot. In the spring, the shelter opens in stages after the frost has stopped, best in cloudy weather so that the young roots do not get a sunburn.

Attention! Kerria, which suffered from frost in the winter, quickly recovers in the spring, but does not bloom so abundantly this year.

The plant is propagated by cuttings, root suckers or taps, which take root quickly. It is recommended to transplant offspring in early autumn, and cuttings and layering - in April.

Kerria Japanese in landscape design

Thanks to similar care rules, kerria goes well in the garden with magonia, weigels, forsythia and deuces, which bloom in the spring. Due to the fear of winds and drafts, it is better to plant a shrub to protect against them, along with other flowering bushes, such as meadowsweet or vesicle. Kerria looks beautiful and elegant surrounded by late-blooming irises and tulips, as well as next to the autumn buzulnik.

Bushes planted along the fences and facades of buildings, along the paths and on the alpine hills attract admiring glances. Kerries go well with coniferous plants in various compositions of landscape design. It can be performed both in the form of a single landing, and in the form of a group.

Kerria Japanese is the one and only of its kind, it is easy to care for and not susceptible to disease, not afraid of pests. Planted on the site, it will organically complement any design and bring its own zest to it.

Kerria Japanese Pleniflora comes from Japan, mainly from those regions where mountainous terrain prevails. There are several varieties of this plant in China. It is beautiful and unique in its kind. Most often used by gardeners for decorative purposes to decorate landscape design personal plot. In this article, we will tell you how to grow kerria Pleniflora on your site.

Kerria Japanese Pleniflora: botanical description of the plant

Kerria japanese Pleniflora is a deciduous shrub. It reaches a height of 2 m. It begins to bloom in May even before foliage appears on it. Flowering lasts a fairly long period of time - 25 days. A unique feature of this plant is the fact that it blooms again in autumn.

The shrub has an elegant shape, it has beautiful rich green foliage, so even in a non-flowering state it is very beautiful both in summer and in autumn, when the leaves turn bright yellow or red. The only drawback of Japanese Pleniflora kerria is its low winter hardiness. In order for her to survive the cold season, she must be covered. Otherwise, in spring, the shrub will not bloom well, and the shoots will practically not recover. Kerria shoots have green color, outwardly they look like cereal straws. The shrub has an abundant root system, which looks like a sparse turf.

Kerriya has 2 forms:

The main one, on which the corolla of the flower is simple. It consists of 5 petals, the diameter of which is 5 cm.
Terry, on which the flowers look like small roses. They begin to grow at the top of old branches and in the axils of the leaves.

Kerria Pleniflora looks better if it is planted in a mixed flower garden where low coniferous spruces, arborvitae, junipers, roses, hostas, and spireas grow.

Kerria Japanese Pleniflora: features of plant propagation

Kerria Japanese Pleniflora propagates by cuttings of lignified and green shoots, although some also practice the method of dividing the bush. How cuttings work:

Cut lignified cuttings in April. If you are going to use green cuttings, then do the procedure in June.
If the cutting has one internode, then it must be planted in a cold greenhouse, where there is light partial shade.
The cutting will take root very well in any circumstances, but this process will take a long time.
The stalk should overwinter in the place of its main growth. After a year, it needs to be transplanted for growing.
Developed cuttings can be immediately distributed over plastic containers so that they turn into small bushes that can already be planted in a permanent place.

Kerria Japanese Pleniflora: planting and care

Planting Kerria Pleniflora

According to the reviews of Kerria, the Japanese Pleniflora is easy to land, but still, a few landing rules must be followed:

The place where kerria should grow should be well lit, but it is important that it is closed from the wind. Penumbra is also allowed, but keep in mind that with it, the flowering of kerria will not be so plentiful. Here, too, there is one caveat - if the flowers of kerria are constantly under the sun, then they can burn out, become pale.
The soil for kerria requires fertile, loamy. It should also be well hydrated.
It is necessary to plant a shrub in the spring (preferably before the buds appear on the plant). In autumn, you can also plant, but 1.5 months before the moment when persistent frosts begin.
A pit 60x60 cm is dug. It is fertilized with compost, which must first be mixed with garden soil, ash and any mineral fertilizer.
The root neck of the kerrea should not go deep.
After the plant is planted, it must be well watered and mulched.

As soon as the plant takes root and begins to bloom, it needs to be provided with proper and high-quality care.

Watering Kerria Pleniflora

Kerria loves moisture very much, so it should be watered regularly, but not flooded, because excess moisture will lead to disease. Kerria should be watered abundantly only during the summer heat. At the same time, make sure that there is no stagnation of water in the soil.

Feeding Kerria Pleniflora

After the kerria has faded, it must be fertilized with mullein. 14 days after applying the first portion of fertilizer, you need to repeat the procedure. If there is no mullein, use compost mixed with ash.

Pruning Kerria Pleniflora

To keep Kerriya beautiful decorative form, it needs to be cut:

In the spring, cut off all the branches that are somehow damaged - broken, frozen.
Healthy branches need to be shortened by 1/3 so that branching is stimulated in this way.
Those shoots that have faded must be cut out so that new buds appear on others.
Old branches, which are already more than 5 years old, are also cut without fail in order to rejuvenate the shrub.
If the shrub is too thick with branches, it needs to be thinned out.

Preparing kerria Pleniflora for winter

Kerria must be properly prepared for the winter cold:

This process is carried out mainly in October in dry weather.
For this, the bush needs to be bent a little, to lay a completely dry cloth under it, which will serve as a bedding (foam plastic is also suitable for this purpose).
Fix it all with a frame made of stakes. He will hold the branches of the kerria so that they do not break under the load of snow.
From above, cover the bush with dry foliage (shavings or a double layer of lutrasil can also be used).
Make sure the shelter is dry and well ventilated. If this is ignored, then the bushes will begin to rot, and, therefore, hurt.
In the spring, the shelter from the cold must be removed. Wait until the cold is completely over, and the weather outside the window will remain cloudy for some period of time.
Gradually remove all parts of the shelter.

How to deal with pests of Japanese kerria Pleniflora?

In its native territory, the shrub reaches a height of up to 3 meters. In our climate, Japanese keriya has compact dimensions - 1.5-2 m in height and width.

Bright yellow double balls of flowers appear in the spring, exuding a barely audible aroma reminiscent of the smell of dandelions. You can admire the abundant flowering of keria for a month. In autumn, the shrub blooms again, although not so magnificently. There are also non-double forms of flowers resembling yellow butterflies sitting in the axils of bright green leaves. Keria japonica was called the "Easter rose" for its early flowering, many florists call the shrub "Japanese rose".

The twig-like shoots of keria are also decorative, they are yellow-green in color and seem grassy. The winter-hardy plant is unpretentious and does not require special growing conditions. More recently, Japanese keria was difficult to see in horticultural plots. Currently, this ornamental flowering shrub has appealed to many summer residents and has taken its rightful place in the garden.

For successful cultivation Japanese keria is required to choose the right place for planting and carry out simple rules of agricultural technology that every gardener can do.
Applying annual pruning of the shrub, watering and feeding the plant, you can achieve lush flowering of keria for many years.

Where to plant

Keriya Japanese is demanding on the planting meta. The plant does not tolerate drafts and cold winds. The favorite habitat of the shrub is quiet, semi-shady spaces with loose, moisture-absorbing soil. Full shade is also suitable for growing a plant, but the flowering of Japanese keria will be scarce, small flowers will not show beauty in full force.

Keriya japonica can also grow in open sunny places. But it should be remembered that the shrub loves moisture and in a dry, dry summer, keria must be watered and the soil must be kept moist. In the bright sun yellow flowers Japanese keria partially burn out and lose their decorative effect.

Keriya japonica looks great as a tapeworm when planted on the lawn. The bright green grass contrasts beautifully with the yellow flowers of the shrub. Successful planting neighbors will be forsythia, weigela, mahonia and action shrubs - plants that bloom in spring and have similar growing conditions. Keriya Japanese can also be used as a beautifully flowering hedge. If garden plot blown by cold winds, the plant is planted in a quiet place in the garden near trees and bushes.

In the garden, Japanese keria looks good in mixborders with primroses: bergenia, tulips, daffodils, primroses, hazel grouses.

Growing features

1. Keriya japonica is a fast growing shrub. Annual pruning - required condition for abundant flowering plants. If you let the development of keria take its course, then the bush will quickly lose its decorative effect and the number of flowers will noticeably decrease.

Every year after flowering, a plant should be formed: cut out old shoots, shorten branches by one third, cut off excess stems. This stimulates the lateral growth of new branches, on which new flowers will be laid, and young shoots will get stronger over the summer and will delight you with a lush color in the spring. Root shoots can be lightly pinched to encourage branching.

In late autumn, when the foliage falls and the skeleton of the shrub is well exposed, it is convenient to examine the keria bush from all sides, trim the crown, remove excess branches and complete the formation of the bush.

2. The roots of Japanese keria are located close to the surface of the earth, so the shrub forms a lot of shoots with a diameter of 1.5 m from the mother plant. Loosening the shrub is not recommended to avoid damage to the roots.

3. After flowering, the plant should be fed with organic or complete mineral fertilizer. Feeding can be repeated after two weeks. At this time, laid flower buds for next year.

4. You can increase the amount ornamental shrub Location on. practiced different ways growing a plant. Keria successfully reproduces by layering, green cuttings and shoots that grow rapidly near the mother plant. Gardeners prefer to propagate keria overgrowth. It is easy and the plants take root easily.

In autumn, a young shoot is dug up and transplanted to the place of future permanent growth. Suitable for planting light loamy moisture-intensive soils. Dense soil is not suitable for growing a plant. Planting pit filled organic fertilizers and compost. After planting, the young bush is watered, and covered with spruce branches for the winter.

5. Keriya Japanese is resistant to various diseases and pests. The shrub does not require chemical treatment.

6. Keriya Japanese quite calmly endures cold winters. Only young plants planted in autumn need shelter. In severe frosts, the ends of the shoots can freeze slightly and the bushes sometimes freeze to the surface of the snow. In spring, the shoots grow back and flowers appear in the axils of the leaves. If the plant grows in a climatic zone with severe winter frosts, it is recommended to pin the shoots to the soil and cover with spruce branches or thick lutrasil.

Planting an elegant Japanese kerria in open ground is a sign of excellent taste and an application for an exclusive. The main varieties of the shrub produce bright yellow flowers that at the same time look like small roses, mini-suns and fluffy pompoms. The contemplation of the flowering kerria gives pleasure to the owners of the backyard or suburban area and their guests. At the same time, growing a crop and caring for it does not cause difficulties, which is especially important for inexperienced gardeners.

Description: varieties and varieties of shrubs

The mountains and forests of Japan and China are considered the homeland of kerria. The shrub belongs to the Rosaceae family and is the only representative of its kind. But it has many forms and varieties with yellow flowers. The most popular among them are:

Pleniflora;
golden guinea;
Simplex;
Variegata and others.

Very rarely there are kerries with white flowers - for example, Albiflora.

kerria bush

The bush is deciduous, grows up to 2 m. The leaves are green, after summer they turn yellow. Kerria grows quickly, and blooms twice: in spring and autumn. But in the interval between these periods, individual flowers also appear on it.

Planting a plant on the site

The optimal site for planting kerria in open ground- a well-lit place without direct sunlight. Penumbra is also acceptable, but it affects the quality of flowering. The soil should be fertile, moist, preferably loamy. Hole parameters - 60 × 60 cm, depth - up to 45 cm.

A glass of ash, a bucket of compost mixed with garden soil, and 60-80 g of complex mineral dressing are poured into each hole. The root neck of the seedling is not buried, the hole is sprinkled with soil. After that, the young plant needs abundant watering and mulching. In the first 2 weeks, hydration should be plentiful, then the amount of water is reduced.

Attention! Usually the seedling is rooted in the spring, before the buds appear. But you can do this in the fall, for 1-1.5 months. before the cold.

culture care

In order for the shrub to look as great on the site as in the photo, it needs to be properly cared for:

kerria flowers

Abundant watering. Kerriya loves to drink, especially when it's hot. Just make sure that you do not inadvertently overmoisten the soil, because the plant does not tolerate stagnant water well.
Pruning. Considered the most main part Japanese rose care The shrub grows quickly, so the procedure is carried out often. After winter, frozen, broken shoots are removed. The rest are shortened by a third to stimulate branching. In summer, faded branches are cut to 1/4. Also, the bush is regularly thinned out.
Rejuvenation. All plants older than 5 years need it. It is necessary to cut 5-7 old shoots to make room for young shoots.
Shelter for the winter. If winters in your area are full of snow, it is enough to bend the shoots of kerria to the ground and cover them with coniferous branches. This should be done in October or November, in dry weather. For more serious preparation, lay the bushes on foam or other dry bedding, fix with a frame of pegs, sprinkle with shavings or dried leaves and cover with a double layer of non-woven material. The structure must be breathable. In the spring, the shelter is removed gradually so as not to provoke sunburn on the plant. This is best done on cloudy days when the threat of a frost has passed.

Attention! The most demanding on the conditions of cultivation and maintenance of kerria varieties Picta and Albomarginata.

Fertilizer and top dressing of the Japanese rose

You need to start top dressing after spring pruning. You can take humus and ash, scattering it around the shrub (100-200 g per 1 sq. M). In summer, after flowering, cow dung infusion is used. After 2 weeks, you can apply this fertilizer again or replace it with compost with ashes. Some gardeners advise from April to October to feed all varieties of Japanese roses with mineral complexes with nitrogen, phosphorus and calcium. Frequency - 1-2 times a month.

Advice. It is necessary to apply fertilizers only from the second year of the life of the shrub, so as not to burn the roots of a young plant with dressings.

Plant propagation: methods

One of the easiest methods to propagate a Japanese rose is by dividing the mother bush. It is not necessary to extract mature plant and split it into several elements. You can do it easier:

dig up side shoots (shoots);
root them in partial shade, making holes measuring 0.5 m x0.5 m;

Mature bushes require anti-aging pruning

before planting, pour fertilizer into the holes - compost;
cover a young bush with soil;
the final stage is watering and mulching.

Attention! This method of reproduction is relevant during the transplantation of kerria in the spring or in the autumn.

The shrub is effectively propagated by cuttings. The process looks like this:

At the beginning of summer, cut from annual green shoots that are already lignified, 6 cm long branches with two buds. Make the cut oblique.
Dig the cuttings in a greenhouse, in a cool, shady place.
Organize a good watering.
In autumn, transplant young shoots into open ground. Next spring they will be ready to plant in their permanent location.

Another method of propagation is with the help of horizontal layering. In the spring, before the buds open, you need to make grooves 7 cm deep next to the bush. Growing shoots should be carefully laid there and pinned with wire. After 1.5–2 weeks, young shoots will appear from the kidneys. When they reach a height of 10-15 cm, the grooves are sprinkled with soil, leaving only the tops of the shoots on the surface. It will be necessary to plant them in a permanent place next spring.

Diseases and pests of shrubs

It seems incredible, but ailments and pests bypass the kerria. Gardeners are not aware of the occurrence and reproduction of bacteria, viruses, fungi or insects on the shrub. Valuable quality greatly facilitates the process of growing and caring for the crop. At proper care Japanese rose even disease prevention is not required.

Kerria is not attacked by pests

combination with other plants. Use in landscape design

In open ground, kerria is afraid of drafts and can even break. Therefore, practice planting it in the company of other shrubs. The optimal combination with Kuril tea, spirea, meadowsweet or vesicle. An amazingly beautiful landscape, worthy of an artist's brush or a photo in a colorful magazine, will be created by an ensemble of kerria with different varieties of conifers, Japanese maples or rhododendrons.

In spring, the shrub will become a wonderful backdrop for aquilegia, terry tulips, purple dwarf irises, phlox, muscari. In summer, he will make a wonderful duet with a sparrow, in autumn - with a flowering buzulnik. Kerria also goes well with action, weigela, mahonia, forsythia. Plant it next to periwinkle, forget-me-not, bergenia, primrose, hazel grouse, lungwort, geyhera, witch hazel, camellia - there are a lot of options!
