A variety of horticultural crops requires adherence to special rules of their agrotechnics. There are secrets of an experienced grower who help turn any piece of land into a blossoming paradise. Care of astilba in the fall according to the rule of agrotechnology will help preserve the plant in any climatic zones. Before covering the plant for the winter, you should know how and when to properly transplant the shrub. Astilba is a very beautiful plant and deserves timely and regular personal care. But not always care is in compliance with temperature standards, irrigation, etc. of things. Also a very important process is transplanting. It depends on the activity of fruiting, as well as the type and health of the future bush. Today we will tell you how and when to correctly astilba transplant, so as not to harm the flower and get them the maximum benefit.
Astilbe transplant - how, when and why?
Actually astilba grows in one place before 10 years and without any transplantation, but if you still want to admire its lush bushes and healthy appearance - then we advise you to carry out this procedure every 3-4 of the year. This is the optimal time, since it is during this period that the process of aging of the roots begins and the astilbe blooms are no longer so active, and the bush itself slowly fades and the buds begin to die. Astilbe transplantation may be required only with a strong depletion of the soil. How, when and why to do it, you can read further in the material.
You also need to know another specificity of astilbe - over time, its roots, together with the kidneys, begin to grow upward and eventually break out. As a result, they can be badly affected by extreme heat and winter frosts. Flowering in this case may completely stop. When transplanting, the rhizome of astilbe is cut with a very sharp knife (so as not to harm the plant) for the necessary number of parts. Each separated shrub must have at least three buds at the base of the root system. Immediately after dividing the bush, place the roots of future plants in a container with water - this will contribute to the independent growth and development of the plant.
When you have started the process of planting, do not forget to keep the distance between the bushes - not less than 40 centimeters, so that not only flowers, but also the leaves of astilba can grow into their full strength. Depth of planting is determined by the kidneys - they must be immersed in the ground at 3-4 centimeters. Then sprinkle mulch (peat or humus will do) with a layer of two centimeters. This way you can avoid weeds near the bush and retain moisture in the soil.
When can I replace astilba
Since our bush constantly manages in moisture, especially in summer, the best option is to perform a transplant in spring or autumn, when there is still (or already) not such a scorching sun. When it is possible to transplant an astilba with the minimum losses for a plant - each gardener solves independently. The preferred option - the end of August - early September. The flower will take the procedure much easier, and therefore the result will be better. Some gardeners argue that transplantation can be done even when the first buds and flowers have already appeared on the bush - it is important to do everything very carefully: you need to replant it together with a clod of earth and water it regularly. That is, even the growing season will not have a particular impact on the effectiveness of the transplant. They believe that the only thing that can prevent a high-quality and efficient transplant is the lack of sun and the absence of moisture.
When to plant astilba?
To get a beautiful and healthy plant you need to know not only how to plant a bush, but also when. Astilbe recommended to land in spring or autumn. In the spring - after the threat of frost finally passed and sprouts can be planted immediately on open ground. After a month and a half, it will bloom (at the turn of June and July). When planting astilba - depends largely on the climatic conditions of a particular region.
If you want to get flowers for the next year, then you can plant seedlings only in the fall, when the summer heat subsides. Planting conditions are the same, it will just bloom not so soon.
The pit where you plan to plant astilba should be two times wider than the root system so that you can prevent its accidental damage and have a depth of at least 15 centimeters. Loose earth, which is formed near the bush, will contribute to more comfortable conditions for the growth of astilbe.
After planting, the pit is covered with clay soil (the same texture as the soil next to the bush). Also check how the soil is tamped next to the new plant to make sure that all air spaces are removed.
How to shelter astilba for the winter?
In the first year, in order for the plant to survive the winter well - do not let it bloom. It is necessary to immediately trim all flower stalks so that all the forces of the flower go to the formation of buds in the rhizome. Also, the first time you need to regularly weed the bush, and after it grows out - then the need for this procedure will disappear by itself. How to shelter astilba for the winter and at what time it is better to do it?
The same layer of mulch will help you to prepare and transfer the wintering, as well as performing several other functions, which we have already mentioned a little higher.
If you live in the middle lane, then you will not need shelters for astilba for the winter - this is one of the most cold-resistant flowers among perennials that tolerate shade conditions. There is a danger of late spring frosts, but if before that you met all the conditions, then your flower will certainly retain its decorative chic and beauty.
Older shrubs (4-5 years) are more sensitive to winter frosts, and all because their roots gradually become bare and not protected. Place a frame of wood or metal near the bush, and fill the space around it with foliage and stretch the spunbond from above. In order to protect our structure from moisture, we advise you to cover it with plastic wrap, which is pressed against bricks for reliability.
