What diseases can attack asters and how to get rid of them: a short guide
The annual aster has won the hearts of flower growers because it is able to maintain its decorative appearance until deep frosts.
If you are thinking about decorating your plot with asters or have already planted seedlings here, it would not hurt to learn about what diseases these flowers are susceptible to. Anastasia Kovrizhnykh, an expert of the online publication BelNovosti, agronomist and landscape designer, told us about them.
The main enemies of Chinese asters are fungal diseases such as fusarium or black leg.
Therefore, before planting plants in the soil, it is recommended to steam them or water them with a weak solution of potassium permanganate - for prevention.
In addition, try to avoid using fresh, unrotted manure as fertilizer.
Another effective measure would be not to use for asters a place where tulips, gladioli or clarkias used to grow.
At any signs of fusarium, you should act according to the same scheme - use watering with a warm solution of potassium permanganate.
If the damage can be described as severe, when the stem and leaves are damaged, due to which the aster cannot open, the plants should be dug up and destroyed by fire - there is, alas, no other way out.
