Chrysanthemum is considered resistant to diseases and damage by pests. However, the aphid is such a pest that it does not bypass this flower. Small insects can completely destroy the bush if they are not dealt with.
Details
If there are no drugs against aphids at hand, and you see that the bush needs to be saved, then you can use folk recipes. Take ammonia, dilute it 1:10 and sprinkle the chrysanthemum bush. Repeat the treatment after 2-3 days.
You can also make an infusion from bulbs. To do this, you need two handfuls of onion peels, pour 1 liter of boiling water and boil for 5 minutes. Leave for 1 day to infuse and then sprinkle the plant.
Citrus peels will also help with aphids. Pour a handful of dried, crushed peels with 1 liter of boiling water, put in a dark place for a day, then strain the infusion and treat the flower.
You can make a soapy solution. Take 2 tablespoons of grated soap, dissolve in hot water, cool the solution and treat the chrysanthemum. This is the fastest and most effective way.
