Rhubarb Companion Plants: A Very Detailed Guide

Pinterest Hidden Image

Growing a garden can be intimidating, especially if you’re new to gardening. But one of the easiest plants for beginners is rhubarb! Rhubarb grows well in many different soils and climates, but it does require some extra consideration when choosing companion plants because it takes up quite a bit more space than usual crops do.

Companion planting with rhubarb should always include three main considerations:

  • How tall they grow or shade will block out sunlight from reaching other plants.
  • Whether certain plant varieties might crowd each other out. Taller growing companions need to stay away from shorter ones as opposed to near them,
  • What benefits that particular crop provides by being planted nearby.

Companion Planting – Fact or Fiction?

It might sound too good to be true but it really isn’t! Companion plants improve your chances of success when gardening by providing support through mutually beneficial relationships.

It is possible that companion plants can make you more successful with less work because they do some of the jobs for you! For example, mint will deter pests from eating vegetables, asparagus will help loosen soil, and garlic will repel aphids.

Companion plants can also help fight off diseases and improve your soil quality while improving the overall health of those plants in proximity to each other.

Because companion planting is not a one-size-fits-all concept, you may need to do more research on the specific plants that work best for your specific goals and environments.
