Companion planting can help with saving space in the garden and can help with insects that can harm or benefit your crops. In this article, we go over what are good companion plants for blueberries and what not to plant with blueberries.

Blueberries grow as a shrub, so companion planting is not quite the same with blueberries as it is with other vegetable crops. How big the shrub grows will depend on the variety. They also can live up to 30 years and sometimes even more, so with most companion plants for blueberries you will want other perennials.

When planting your blueberry shrubs it is best to plant them with other plants that like acidic soil as they prefer low pH levels. Sometimes this will involve you having to make a special soil.
