Aster for many is a favorite autumn flower. But some gardeners complain: it is necessary to sow it for seedlings from mid-March, and then there are many problems with growing. In fact, this culture is not so difficult, you just need to know its whims. Asters are light-loving plants; they bloom profusely only in the sun. They develop better on sufficiently moist soils, but they equally poorly tolerate both drought and waterlogging. They can grow on any soil, but light loams and sandy loams are most favorable for them.

The aster has a powerful root system, the bulk of the roots is located in the soil at a depth of 15-20 cm. The roots damaged during planting or loosening are easily restored, so asters can be planted at any age and successfully transplanted even with buds and flowers. In late summer and autumn, asters are replaced by other fading letniki when decorating flower beds, balconies, they are transplanted into pots to decorate the premises.

Since autumn, the area for asters is filled with organic (humus, peat-composts - 4-6 kg / m 2, non-acidic peat -10 kg / m 2) and mineral (phosphate rock, superphosphate - 80-100 g / m 2) fertilizers. If the soil is acidic, add ground limestone, chalk or fluff lime (80-100 g / m 2). Nitrogen and potash fertilizers are applied in the spring after the snow melts.

Usually asters are grown through seedlings. The optimal sowing time in central Russia is from March 15 to April 15. The soil for sowing is calcined in the oven or a few days before it is spilled with a solution of foundationol (1 g per 1 liter of water). This will help protect yourself from the black leg. If there are many varieties, then it is better to sow in the grooves and put labels with names. Then the seeds are covered with light sifted earth or sand with a layer of 0.5-1 cm, moistened from a watering can with a fine strainer or from a spray bottle. After that, the boxes or bowls are covered with paper. At a temperature of 18-20 ° C, seedlings appear in three to seven days, then the shelter is removed.

The seedlings are placed as close to the light as possible. If the seedlings stretch out and lie down, you can add some calcined sand.

Plants are fed 7-10 days after picking (urea, crystallin - 1-1.5 g per 1 liter of water). Two to three weeks before planting in the ground, the seedlings begin to harden, gradually accustoming them to fresh air. Hardened seedlings can withstand short-term frosts down to minus 5 ° C.

Seedlings are planted in flower beds in the second half of May. After planting, the plants are abundantly watered and mulched with peat. This mulch retains moisture well in the soil, regulates its temperature and inhibits the growth of weeds.

Planting is desirable after three weeks to feed with a complex mineral fertilizer (40-50 g / m 2). And after another two weeks, feeding is repeated. During the budding period and the beginning of flowering, only potash and phosphorus fertilizers (25-30 g / m 2) are applied, and nitrogen is excluded. Top dressing is usually combined with watering.

The soil around is loosened often, but shallowly, weeds are regularly removed. Asters are watered only in drought.

The biggest problem for asters is fusarium wilting, or fusarium. The disease manifests itself primarily on the lower leaves and the lower part of the stem, gradually spreading to the entire plant. Affected leaves first turn yellow and then turn brown, curl and hang. Longitudinal dark stripes appear at the root collar and above. Severely affected plants bend and then wither. The affected plants are dug up and destroyed, and ash or fluff lime is poured into the holes, mixed with the ground and leveled.

Young plants are very rarely affected by Fusarium, usually the disease manifests itself during the budding or flowering of asters. Unfortunately, the means of combating this disease are unknown and there are no varieties that are completely resistant to it. However, hobby growers should be aware of some preventive measures that will help mitigate the epidemic.

First of all, asters are returned to their original place only after four to five years, since the fungus-causative agent of the disease persists in the soil for quite a long time. If the plot is small and it is not possible to observe crop rotation, then in the place where the aster planting is planned for the next year, in the current year they sow calendula, nasturtium or plant seedlings of petunias or marigolds, which heal the soil with phytoncides.

Before planting asters, add humus or compost to the soil, but not fresh manure, which will only provoke disease.

Soaking the seeds before sowing in a 0.03% solution of microelements for 14-18 hours and foliar feeding with them during the budding period will also help protect plants from fusarium. In addition, the flowers become brighter from trace elements.

Plants grown by sowing seeds in the ground (early May) immediately to a permanent place are more resistant to disease. In this case, only early flowering varieties are used.

There is a little trick to admire the blooming asters from October to December. The seeds are sown in mid-June and the plants are grown as usual until mid-September. Then the asters are carefully transplanted into pots with a diameter of 10-15 cm and placed on the lightest window in the room. Low-growing varieties are best suited for this.
