Companion Plants That Will Be A Pumpkin's Best Friend

Pumpkins (Cucurbita pepo) are an iconic fall vegetable that many love to include in their home gardens. Often, this type of gourd proves to be fairly simple to grow and very rewarding when it's time to harvest your pumpkins. With just a bit of regular maintenance, pumpkin plants bloom in the summer as they are provided with direct sunlight, moist but well-draining soil, and lots of space to grow. However, they have the ability to grow even larger and produce more when planted with the right companions.

Companion planting methods have been used for ages to make the most out of vegetable, flower, and herb gardens. Pumpkins can be an important part of this, but it all depends on the types of crops you're growing. In general, pumpkins won't grow well with broccoli, cauliflower, kohlrabi, other members of the cabbage family, and potatoes. Yet, there are dozens of other vegetables and herbs that can benefit your pumpkins simply by growing nearby. Keep reading to learn about some of our favorite options.

Tansy (Tanacetum vulgare) is a weedy perennial in the daisy family. Though it can be a difficult herb to control, it isn't all bad. The leaves and flowers' pungent fragrance helps scare away a few common garden pests. Specifically, tansy repels Japanese beetles, which are known to eat their leaves and fruits. As a bonus, the herb is also reported to increase the potassium present in the soil.

You might consider planting radishes (Raphanus sativus) next to your pumpkins if you aren't a huge fan of the red vegetable's taste. The root vegetables are known to be very attractive to flea beetles, which also pester potatoes, sunflowers, squash, and more. By growing radishes near pumpkins and other crops that flea beetles often snack on, you can trick the pests into eating the radishes instead of your more valuable veggies.

You might already know that pole beans (Phaseolus coccineus) can either be the best or worst thing for your garden depending on what you're growing. When planting pumpkins and corn for your fall harvest, consider adding pole beans to complete the "Three Sisters" method. The beans fix the nitrogen in the soil while corn plants provide a natural trellis. On the ground, the pumpkins offer a living mulch-like effect in return.

The borage plant (Borago officinalis) is an herb that is grown for its edible leaves and flowers, as well as its ornamental blue star-shaped blooms.

Their leaves can be harvested to make a soothing tea, dried out and given to cats, or grown in the garden to deter pests from eating your vegetables.

Similarly to pole beans, white clover (Trifoleum repens) planted near pumpkins can fix the nitrogen in the soil they're growing in. Balanced nitrogen helps pumpkins and other vegetable plants produce even more crops as they grow larger and healthier. Another thing that aids in a healthy harvest is pollinators, which white clover can also help with. During its bloom time, clover attracts butterflies and honey bees.
