Most aphid repellent plants like to be watered regularly, but it's important not to overwater them. Too much water can lead to root rot, which can kill the plant.

To prevent aphids from becoming too comfortable in your garden, rotate your crops regularly. This will help disrupt their breeding cycle and keep their population under control.
