An annual crop
The summer aster from China consumes all of its strength within a year. It grows in spring to bloom in summer and well into autumn. She does not build up energy reserves. It only trains its seeds. These can be used for propagation in the next year.
For this reason, the summer asters are not perennial plants like the autumn asters. They are annual plants. They need to be replanted or sown every year.
The plant dies after flowering
Regardless of how much you have cherished and cared for your summer aster, in autumn the plant will perish irrevocably. This means:
- it no longer needs fertilizer
- there is no need to cut back
- it doesn't need winter protection
- it is torn from the ground and disposed of
Re-sow after winter
In principle, sowing summer asters is uncomplicated. The germination time is short, as is the effort and the germination rate of the seeds is high. Therefore: If you want to see summer asters in your garden again next year, you should sow them again in spring.

- like to prefer home from March
- Cover seeds lightly with soil and press down
- Keep the substrate moderately moist
- Germination temperature 10 to 20 ° C

Summer asters should not be planted in the same place every year. Since these plants tend to get sick from the aster wilt, it is advisable to change location every year.
