Black aphids are a real nuisance for most amateur gardeners. If you want to get rid of the annoying little animals, you should not use environmentally harmful poison right away.
Instead, it is worth resorting to natural remedies to get aphid infestation under control. The use of so-called plant manure, which can be easily produced at home, has always proven to be particularly promising. A decoction of tobacco or vegetable oil diluted with water can be used to kill black aphids.
