How to grow aster on the balcony

1. Planting time

The cultivation of aster is mainly carried out by sowing seeds. The flowering period of aster lasts for a long time, from early summer to late autumn. Its planting time should be chosen during its non-flowering period, which can be between November of each year and April of the following year. However, if it is in the drier areas in the north, early spring in March and April is more appropriate.

2. Planting method

sowing

Prepare the container and nutrient soil for sowing seeds in advance. A large plastic sowing pot can be used as the container. You can add garden soil, silt and fermented bean dregs to the nutrient soil. First, pour nutrient soil into the pot, making sure it is two or three-quarters full from the top of the pot; then take about thirty to fifty seeds and sow them into the pot, and then cover the seeds with a thin layer of nutrient soil until the seeds are no longer visible.

germination

Next, use a small mist watering can to spray water into the pot again. Make sure the soil is thoroughly sprinkled so that the seeds and nutrient soil are fully in contact to prepare for subsequent germination.

Light and water control

Finally, place the flower pot in a ventilated and bright place indoors, but it must be shaded and not exposed to direct sunlight. Before the seeds begin to root and sprout, pay close attention to the soil condition in the pot. When you find that the nutrient soil is dry and cracked, immediately use a fine mist watering can to spray water into the pot five or six times.

Transplanting

After the seedlings sprout, they can be transplanted after thirty days, moving the seedlings from large plastic pots to small pots, with four to five plants in each pot. The current seedlings can be called aster seedlings. Pay attention to watering and fertilizing, and the aster seedlings will slowly grow strong.

temperature

Aster is widely distributed in the coastal cities of Northeast China in my country, and rarely distributed in Yunnan and Sichuan in the south. It likes mild sunshine and moist soil but cannot tolerate floods and severe cold. It is best to sow it in spring and autumn when the temperature is around 14℃ to 16℃. When the temperature is controlled at 18-21℃, sow the seeds, and they will germinate in about one to three weeks. When the temperature is below 5℃, warming measures should be taken for the seedlings. As the temperature gradually rises, the seedlings grow bigger and stronger.
