Companion plants can usually be planted alongside or under citrus trees. The two main factors are how much sun or shade the companion plants need and the size of the citrus tree.

In general, younger citrus trees can compete with other plants in establishing their root base. When the citrus trees reach 3 feet or more in height, you can start planting companion plants underneath. just make sureKeep companion plants at least a foot away from the tree trunk.

What not to plant near citrus

If you plant near citrus trees,Avoid plants with deep rootsas they compete with and can even damage the shallow roots of citrus trees. These plants include tubers and root vegetables such aspotatoes, sweet potatoes and carrots,along with other fruit trees.
