The summer asters, which originally come from China and are related to the well-known asters, are not perennial, but only annual and therefore have to be replanted or sown every year. But what should you take into account and what is important?
How do you properly care for summer asters?
Summer asters prefer a sunny to partially shaded location with well-drained, fresh, nutrient-rich and slightly moist soil. Sowing takes place between March and May, ideally at a germination temperature of 11-15 °C. The flowering period lasts from July to October if wilted flowers are removed regularly.
Does the summer aster like to grow in full sun?
The summer aster definitely likes a location in full sun. She likes it bright and warm. But a location in partial shade can still be an option for them. It is also important to offer her an airy rather than a sheltered place.
What properties should the soil have?
The soil at the location also plays a significant role. It is not important whether you plant the summer aster in the bed or in a pot or in the balcony box. It is important that the soil is permeable. Furthermore, it should be as follows:
- fresh
- nutrient-rich
- slightly moist
- humic to sandy-loamy
When do you sow summer asters?
Between March and May is the optimal period for sowing summer asters. If you decide to start growing at home, you should do it between March and April.
Direct sowing outdoors is possible from mid-May (summer asters do not tolerate frost). If you don't have space at home for the pre-culture, you can also prefer the plant in the cold frame (€79.00 on Amazon) or greenhouse.
How exactly do you approach sowing?
In order to obtain robust plants, germination temperatures between 11 and 15 °C are perfect! The seeds are placed two or three into a pot. The sowing depth should not exceed 1 cm. Keep the substrate moist! On average, it takes 2 to 4 weeks for the seeds to germinate.
When and how does this plant bloom?
Summer asters usually bloom in midsummer, i.e. from July. The flowers are colored pink, red, white, yellow or purple. The flowering period can last until October if wilted flowers are removed regularly. After the flowering period, the annual plant does not need any care but can be disposed of.
Tip
When sowing, don't forget to separate the plants later to 15 to 25 cm!
