Aphids make life very difficult for us gardeners. Because they nest on our plants and suck them dry. The lice do not suck liquid from the plant, but sugar.
You must do something about it
The plant can compensate for a slight infestation itself, but if there are too many aphids, something must be done as soon as possible. If there are not that many, you can spray the aphids with a jet of water, otherwise you can also use various beneficial insects. These include ladybugs, parasitic wasps, hoverflies and lacewings. There is no need for pesticides!
Sooty mold grows on the honeydew
If you don't do anything about the aphids, you risk the plant dying. This does not always have to have something to do with the suction. The excrements, the so-called honeydew of the lice, are also dangerous. Sooty mold fungi like to settle on it, which also weakens the plant.
Prevent aphid infestation
You can do something against aphids even before planting, namely by planting robust and less susceptible plants. Incidentally, when it comes to fertilizing, less is more, because lice like fertilizer. Organic fertilizers are best.
