There’s nothing better come Halloween than carving your very own homegrown pumpkin from your garden. And like other crops you grow, you can use companion planting for pumpkins too. In this article, we go over what are good companion plants for pumpkins and what not to plant with pumpkins in your garden.
Pumpkins can be susceptible to infestation from pests such as aphids, cucumber beetles, squash bugs, and vine borers. By using companion planting with pumpkins you can use other plants to help keep bugs away from them.
Good Companion Plants for Pumpkins
- Agastache Rugosa
Agastache Rugosa also known as Korean Licorice Mint will help attract beneficial insects like hoverflies. It will also bring in pollinators.
Beans, such as green beans, are another good companion crop for pumpkins. Beans help add nitrogen back into the soil which benefits growing pumpkin vines.
Corn is a very popular companion crop for pumpkins. The vines from the pumpkin plant can help serve as a ground cover for the corn, helping keep weeds out of the area it’s growing in. This will also help keep moisture in the ground, preventing the corn’s roots from getting too hot. This is also a space-saving companion combo, as the pumpkins can grow between the corn stalks.
Lavender will help attract bees and other pollinators.
