There are many plant companion settings. Plants that help one another out by promoting healthier growth, warding off certain pests, and helping keep the soil's pH at a healthy level for the plants around them. Today we are going to talk a little about using geraniums as companion plants:
Geraniums help brassicas, tomatoes, grapes, aubergines, roses and peppers by attracting pests such as leaf hoppers and Japanese beetles away from other plants. The Geranium is considered a trap crop when used in this manner.
Keep in mind, when you have your watering can out, that Geraniums do not need much water. In fact if over watered damage that can be hard to reverse will be caused to the plant.
