Growing pumpkins can be a rewarding experience. However, you will need to carefully plan to get the most out of your garden space and produce the best possible harvest. One key factor is companion plants. Companion plants are plant species that grow well near each other because they have similar light and water requirements, inhibit pests or diseases through chemical secretions or attract beneficial insects which prey on garden pests. We have a complete list of companion plants for pumpkins you can add to your patch that will ensure a healthy, bountiful harvest.

The Biggest Tip About Companion Plants

There are many different types of pumpkins grown for food or decoration around the world! Each plant is unique unto itself with special requirements for development. For example, some are bushier with shorter vines while others trail and long vine distances.

Some pumpkin plants need excess sunlight to produce fruit, while others can thrive in partial shade. Some are cold-hardy than others (like my favorite variety Cinderella), and some are hot. When choosing companion plants for pumpkins, it’s essential to consider all these factors and which ones work together best.

Make sure your companion plants enjoy the same environment as your chosen pumpkin variety.
