How to grow aster with green leaves and abundant flowers

temperature

Aster likes to grow in cool and dry places. The suitable temperature for growth is between 12℃-15℃. Within this range, the lower the temperature, the more beneficial it is to the growth of the plant, but the flowering time will be slightly extended. It is not frost-tolerant and cannot grow at temperatures below 8°C. Low temperature and short daylight will affect the normal growth of plants. In summer, shading, cooling and ventilation are required.

illumination

Aster is a long-day plant and prefers a sunny growing environment. Long days are beneficial to promote flowering, improve its quality and enhance branching. For cut flower varieties, during the seedling stage, more than 4 weeks of light exposure is required, with daily light exposure of about 14-16 hours. Supplementary lighting is required under natural conditions of short daylight. The lighting needs to be interrupted at night for about 4 hours. After the flower buds appear, the lighting time can be shortened, which is beneficial to promote flowering and can also shorten the cultivation time. If the aster plant is grown only under short-day conditions, the leaves will appear clustered, which will affect its normal flowering.

Open field maintenance

In the case of open field cultivation, apply decomposed organic fertilizer as base fertilizer when preparing the land. After the seedlings are planted and the plants have grown, apply thin cake fertilizer water every 15-20 days. Water the soil in time to keep it moist. After each watering, the soil should be tilled and soil moisture should be retained in time, otherwise the soil will be too wet and it will easily cause diseases. After buds appear, be sure to reduce watering to prevent buds from falling.

Potted plant care

Dwarf varieties are suitable for potted plants, and they should be cultivated in loose, fertile, and breathable sandy loam. The aster potted plants should be placed in a well-ventilated, sunny place for maintenance. Keep the soil in the pot moist during the growing season and apply thin liquid fertilizer every 15 days to make the plant grow vigorously and bloom more.
