You want to grow sunflowers but are not sure what plants to grow with sunflowers? Good news!

I show you the best and worst sunflower companion plants in this article so that you get a better idea of what to grow with sunflowers and what plants you should avoid.

Why do I need Companion Plants for growing Sunflowers?

The truth is that you don’t necessarily have to grow sunflowers with other plants.

Yet, if you grow sunflowers alone, you will still miss out on many benefits good companion plants can provide for your sunflowers.

For instance, good companion plants can loosen the soil, keep it moist, deter pests, attract pollinators and can therefore improve the overall growth behavior of your sunflowers.

While good companion plants have those beneficial characteristics, bad companion plants will often do more harm than good.

Hence, make sure to have a look at the following tables to figure out what plants to grow with sunflowers and why.
