Planting and growing
You can grow these flowers in one place for five years. After this, the plant is transplanted. In general, growing asters is not particularly difficult. It is preferable to acquire and plant seedlings in springtime. Then, by the onset of autumn, your garden will be decorated with these magnificent flowers. For planting, it is best to choose a warm and sunny place that has fertile, not heavy, loose and permeable soil. Adding organic and mineral fertilizers to the soil is mandatory.
Perennial aster can be grown from seeds. However, it must be borne in mind that they bloom only after three years. Late-flowering plant varieties are planted in spring, and early-flowering varieties are planted in the fall season.
It is worth noting that these flowers have almost no pests. Powdery mildew is the most common disease. This disease affects those plants that are grown in the shade. For prevention, you can use "Gumi" and "Fitosporin" (simultaneously).
Asters look good in any landing. However, when growing these flowers, you need to be prepared for blackening and drying of the leaves on the bottom of the stem. Due to this nuisance, planting can be sloppy. Therefore, it is better to plant plants in front of the asters that could hide their lower part.
Perennial asters are transplanted and propagated in springtime. This plant propagates using green cuttings. In spring or summer, young shoots appear on the stems of these flowers, which are used for reproduction. These shoots easily give roots, grow quite quickly. In this case, strong bushes grow.
Please note that asters reproduce not only with the help of green cuttings, but also with the help of division of the rhizome.
In addition, this plant can be propagated by seeds, but the result will not always be good. Seedlings often grow weak.
Perennial astra is a rather unpretentious winter-hardy plant. It is not allowed to fertilize flowers with fresh manure. In addition, you can not thicken the landing. Otherwise, it can lead to illness. Periodically loosen the soil around the stems (this should be done quite often). Weed regularly.
Flowers need to be infrequently, but watered abundantly in dry periods.
It is recommended to add a small amount of potassium permanganate to the water for irrigation. Regularly remove fading flowers and be sure to tie tall varieties. If you fulfill all these simple requirements, then the plants will grow well and bloom profusely.
A week after the seedlings sprout, it is necessary to begin feeding them. For these purposes, use mineral fertilizers, which can be purchased at a specialized store.
In addition, it is recommended to fertilize the soil before you are going to plant seedlings or seeds. Please note that the use of organic fertilizers is unacceptable. To do this, it is better to use compost, humus or wood ash. On well-cultivated soil, you can do without fertilizing.
Perennial asters are an amazing starfall in your flower garden, these are peculiar bright strokes in a beautiful palette of an autumn garden.
