For what year does astilba bloom after planting?

There are 3 ways to carry out this procedure:

  • reproduction by kidneys;
  • dividing the bush;
  • seeds.

You can use a part of a bush with a root of 4 cm and 2-3 buds. Placed on the site in the fall, it will bloom the next season. Saplings rooted in holes for the winter with insulation or planted in early spring, sprout and soon (by August) form panicles.

Immediately after collecting the seeds, sowing can be carried out into the ground, providing shelter for the winter, as well as in containers, be sure to stratify and carefully care for, regular soil moisture. In the first case, a certain percentage of seedlings will appear in the spring. In the second, the seedlings are transferred to the ground by the beginning of June. Seedlings from harvested seeds usually do not retain the characteristics of the original plant. When buying seed in the store, you can wait for the buds a little later, but the growing process itself is very interesting.

Attention! With any method of planting, reproduction in the first year, it is recommended to cut off the buds so that they do not weaken the plant.

Astilba thrives in semi-shaded areas with constantly moist soil. She is intolerant to drought.

Favorable areas for better development - the banks of reservoirs, the shade of trees or the north side of the building. If astilba bushes grow in the garden, which has run out of flowering time, you should not stop watering it. Its roots sometimes grow vertically, spread over the surface and are in great need of moisture. In autumn there are also dry periods, then this is very important.

Astilba care after flowering

Astilba faded, what to do next, in stages and variants:

  • Flower panicles should not be cut off immediately after wilting as they can yield seeds. Half-dry inflorescences also look beautiful in the flower garden, until the end of the season.
  • Before the onset of cold weather, you need to cut the stems of the plant to the level of the soil and mulch it in this place. This is especially necessary if astilba was planted by dividing the roots in the coming spring or early autumn.
  • Trimmed panicles without seeds are to be burned. Although some use them for compositions. Ash is useful as fertilizer. It needs to be scattered over the soil.
  • Astilba after flowering, what else to do? With the onset of autumn, the bush is divided, which makes it rejuvenated. During the winter season, the roots of the plant will harden to a woody state. Therefore, it is more difficult to do this in the spring.
  • Perennial needs feeding.

Now in more detail about the procedure for reproduction of astilba by dividing the roots. When autumn comes, a bud of growth is left on each piece of the underground part. The planted plant will develop in spring and bloom with a significant number of panicles. You just need to mulch this area, and also cover it with spruce branches or straw for insulation from frost.

Astilba mulching

Although this crop is resistant to cold, at a young age it is at risk of disease. Some of the roots grow upward, as a result of which they can become exposed and freeze, especially if there is no snow, and the temperature is significantly lowered. It is possible not to prune and transplant the plant with the onset of the autumn season, transferring the procedure to spring. Care will then be limited to top dressing made under the bush.

When considering how to care for astilba after its flowering, some are interested in why permanent rejuvenation should be carried out. The culture does not grow in one place for over 5 years. You can try to leave it for a longer period. Then you will have to watch the plant wither. The flower will lose its brightness, abundance and splendor of panicles, the decorative period itself will be reduced.

Note! The longer the wilting lasts, the more difficult it will be to rejuvenate the individual. Although for the procedure it is enough to divide the root without transplanting, and then add top dressing.

So, what does autumn astilba need: pruning after flowering, dividing the bush and feeding. Moreover, in the late period, the second fertilization is carried out into the soil surrounding the plant. By this time, the panicles will not only have completely finished blooming, but the seeds in them will also ripen. Potash and phosphorus fertilizers are used in liquid form. In the spring, you can burn the stems this way.

Top dressing in liquid form

After the feeding procedure, the soil is loosened and mulched. The soil between the bushes is covered with sawdust or peat. Needles are also suitable, which protects from frost. Pruning the stems takes place after feeding, when the first snow falls and the cold begins. Sometimes leaves appear on the cuts, dying by spring, yielding to the growth of shoots.So, the astilbe has faded, what to do now is clear.

Council. By propagating the plant with seeds, you can store them directly in the cut panicles.

Florist tips and tricks

When to dig and plant daffodils after flowering

Astilbe can be grown in rows, in groups, including a variety of flower colors: purple, white, almost burgundy, pink and lilac. It is also advisable to combine it with other plants, especially those that quickly fade. Low-growing varieties up to 25 cm are appropriate to plant on an alpine slide or curb.

Question: is it necessary to trim? There are gardeners who believe that dried stems trap snow, which creates a warm pillow, and the cover is also a source of moisture. The opinion that this should help the plant makes sense. But most flower growers consider pruning to be more useful, since in the absence of snow in winter, the roots can freeze slightly, and it will no longer be possible to cover them.
