Higher summer asters are ideal as cut flowers. Smaller summer asters look pretty in stone beds and in herbaceous borders. No matter what variety it is - every summer aster needs a little care.

Summer asters like to have wet feet

What role does casting play?

Summer asters need moist soil to grow and bloom profusely during the summer months. If these perennials are outdoors, they should be watered during the growth phase and during dry periods. With a pot or balcony box culture, watering is necessary regularly. In the summer it becomes an everyday procedure.

Are summer asters dependent on fertilizer?

A nutrient-rich soil is a prerequisite for summer asters to grow well. Therefore, it is best to enrich the soil outdoors with compost before planting. Even after you have disposed of the plant in autumn, it is advisable to mix the old planting site with compost.

Here are some more hints:

  • use liquid fertilizer for potted plants
  • artificial fertilizers are not recommended
  • do not choose fertilizers that are too high in nitrogen
  • rather value a lot of phosphorus
  • too much nitrogen makes summer asters susceptible to powdery mildew
  • you are also welcome to use liquid manure or herbal decoctions

Which disease is more common in summer asters?

It is the so-called aster wilt that does not stop at many summer asters. It means the imminent end of this plant. This is a fungal disease. The fungi cause both the stem base and the root collar to turn brown.

The fungal pathogens block the pathways in the stems. As a result, you can water as much as you want. The leaves and flowers become wilted and look dried up. The entire plant later dies.

In the case of an aster wilt infestation:

  • uproot the plant
  • dispose of immediately in the household waste
  • Do not plant summer asters in this spot for the next few years
  • select a new location each year

How do you deal with the summer asters in autumn?

Since the summer asters are not perennial, you can uproot and compost the plants in the fall. Even if you covered it with brushwood and co in the fall, the plant would not survive the winter.
