Annual Astra is one of the most popular plants. Asters reproduce only by seed. High - 50-80 cm, medium - 30-50 cm, low - up to 30 cm.
So that asters bloomed early, they are grown in a greenhouse or in a box. In mid-March, seeds are sown. For sowing use only fresh land (unused). Take 3 parts of turf land, 1 part of sand and 1 part of well-weathered peat. After the soil has been well watered, river sand or well-washed coarse-grained sand is poured on top with a layer of 1.5-2 cm.

Seeds germinate at a temperature of 20-22 °. Shoots appear after about a week. On 1 m2 of box you need 5-6 g of seeds. After sowing, the boxes are sprinkled with sand with a layer of 0.5 cm and watered from a watering can with a small strainer. Boxes need to be covered with a film to keep uniform humidity. When shoots appear, the temperature should be 15-16 ° C, at night it is better to lower the temperature to 4 ° C. Seedlings need to be watered well, but rarely, the soil should not be waterlogged. If a disease appears - a black leg, then the plants are watered with water, in which potassium permanganate is added until a saturated pink color.
When the seedlings get stronger, they feed her. Seedlings dive when she has 1-2 real leaves. Approximately 7-10 days after rooting, seedlings are fed infusion of mullein: 0.5 l per bucket of water. Seedlings are usually fed twice.
You can’t grow aster in one place for several years in a row, as it will be very affected by Fusarium. In the middle lane of our country
seedlings are usually planted in mid-May. Low varieties are planted with a distance of 20X 20 cm, medium - 25 X 25 cm, high - 30X 30 cm.
After planting, the seedlings are watered (about 0.5 l of water per plant), then the soil is loosened and dry soil or weathered peat is added to the roots so that the crust does not form.
Asters can be fed with organic fertilizers on soils where there is insufficient humus content. On fertile soils, bird infusion is fed.
You can sow asters in the ground and seeds. Such plants will be more resistant to bad weather..
Once the soil is ripe, you can sow asters. Seeds are sown on the ridge in the grooves of 1.5-2 cm, after sowing the ridge watered from a watering can with a small strainer. Then the crops are mulched with humus or fertile soil, the grooves are not closed up. Ridges are watered only in windy, arid weather 1-2 times in 10-12 days.
You can sow asters in the winter. Seeds are sown in prepared ridges with grooves 2 cm deep (in the second half of November). Sowing is mulched with humus layer of 2-2.5 cm, weathered peat, which are stored in a frost-free room. The width of the layer is 5 cm. In spring, without waiting for seedlings, focusing on the mulching layer, it is possible to loosen the row-spacings.
Shoots are thinned out when the first true leaf appears. On poor light soils, asters feed with mullein. Before feeding, the area is watered. The site should be evenly moistened. Weeds need to be removed on time. Asters near the plants are only 2-3 cm wide; their root system is located close to the soil. In the aisles, the depth is 5-7 cm.
In autumn, asters can be transplanted into flower pots, and for a long time they will delight with their flowering.
