Japanese Kerria is a beautifully flowering deciduous shrub belonging to
the Rosaceae family. She came to us from China. This overseas guest received her name in honor of Kerr, a London plant collector, gardener who works in a botanical nursery and is fond of varieties of flowers brought from Asia. A plant is an infrequent guest in Russian gardens, apparently due to its southern origin.
In its appearance, Japanese keriya is very similar to a grassy bush: its shoots are completely green and only slightly brown at the very base. Its height barely reaches a meter, but its transverse size sometimes reaches two meters (thanks to the root shoot). The leaves of the plant are ten centimeters, green, with denticles along the edges.
Japanese Kerria, whose photo is especially bright during its flowering period, has several varieties, such as Picta, Pleniflora, etc. It blooms with bright yellow fragrant flowers, very similar to small roses.
In gardens, Japanese terry kerri is most often found, which under favorable conditions can please the eye with golden flowers twice a year. Of non-terry varieties, one can distinguish the Albiflora variety with five-petalled white flowers.
One of the main factors for growing this plant is the right place. Kerry bush loves well-lit sunny areas protected from the cold wind. Landing pit should have a depth of forty centimeters. The earthen mixture is composed of turf and garden fertile soil with humus. Complex fertilizer is added to it .
Japanese Kerria is a fairly
hygrophilous plant, so you need to water it weekly throughout the growing process. In winter, a lot of snow should be poured around its base. The bush tolerates transplants painlessly, the main thing is that this happens in autumn or spring, when there is no leaf cover on it.
In July, after flowering, the plant must be cut off. The branches are shortened to the same height, and the young shoot is slightly nipped. At the same time, root dressing needs to be done. Mullein infusion is best suited for this. The combination of pruning with fertilizer will contribute to good branching and growth.
With careful care, Japanese Kerry will delight not only with its beautiful forms, but also with long flowering throughout the summer.
If the bush grows in the right place, then he does not need winter shelter: enough snow has fallen. Otherwise, the plant must be covered with spruce branches, bending the branches to the ground.
Kerria is most easily propagated by division. Moreover, you do not need to dig out the old bush, you can only, having separated the shoots from it, transplant in the desired place. In addition, the plant also propagates by cuttings, cut with a pair of leaves and planted in light partial shade in a greenhouse, where they must be wintered. And only in the spring the material landed already in the final place - away from the drafts, in a well-lit area of the garden.
In landscape design, this bush is often found in large mixed flower beds in company with Japanese maple and rhododendron. He gets along well with conifers - thuja, juniper and spruce, and fits into the composition with hosts, roses and spirea.
