Chinese aster (Callistephus chinensis), as the name suggests, comes from China and is one of the most popular summer and autumn flowers. The stem is upright, unbranched, leaves twisted broad-oval or triangular, jajowate, coarsely serrated, narrowed in a petiole, large flower baskets, seated singly on long stalks, marginal flowers in a basket – lingual, multi-colored; internal tubular – yellow. A lot of varieties are grown, both differ in height, the color and structure of the basket, and the time of flowering.
The varieties are divided according to the flowering time into: early -flowering from mid-July, medium – from mid-August and late-flowering from mid-September. Asters can reach different heights and that is why we divide them into: dwarf 20-30 cm, medium high 40-50 cm and tall, above 50 cm. The flowers can be single or full structure. In single asters, the center of the basket is filled with tubular yellow flowers; it is surrounded by one or two whorls of colorful ligulate flowers. In full-fledged asters, almost the entire basket is filled with colorful ligulate flowers. Among this group of asters we also distinguish such types, how: peony asters, needle and chrysanthemum.
The use of asters is versatile, suitable for flower beds and discounts, and medium high and high – for a cut flower. Plants require a sunny location, fertile soil, moderately moist, in good culture and disease-free, because they are particularly susceptible to disease – gangrene of the root neck and stem – difficult to fight.
The seeds are sown at the end of March for the inspection or in April for the seedbed. Once the seedlings have formed the first pair of leaves, then they are quilted in the inspection in a 4X6 cm spacing. To avoid plant quilting, we advise you to sow them rarely. Asters hate fresh manure, if necessary, we use compost in quantity 3-5 kg in 1 m2. Plants are planted permanently in mid-May, and even later (can tolerate transplanting even with flower buds). Tall varieties are planted with a spacing of 40X30, medium high – 30X20, and dwarf ones – 20X15 cm.
