The Best Melon Companion Plants


Companion plants for melons can provide several benefits, from deterring pests to attracting pollinators. Marigolds are an excellent choice for a companion plant, as they produce chemicals that repel whiteflies, Mexican bean beetles, root-knot nematodes, and root lesion nematodes.

The strong fragrance of alliums repels cantaloupe’s natural predators, such as aphids and cucumber beetles, making them excellent companion plants for melons. Additionally, allium vines can help repel larger pests like rodents and deer from snacking on them.

Allium plants have a compact growth pattern so they won’t shade cantaloupe plants. However, you should avoid alliums if you plant legumes in the same area, as they can stunt their growth.

Bee Balm

A beautiful flower, bee balm can also attract butterflies and bees to your garden. These beneficial insects can help with pollination and act as natural pest predators. In addition to looking great, bee balm planted near cantaloupe will also help protect it from pests.

The fruit cantaloupe is a delicious one that many people enjoy, and it is a great combination to enjoy both plants together. If you’re looking for a way to enhance the beauty of your garden, consider planting bee balm with other melons, such as watermelons and honeydews.

Bush Beans

Since bush beans fix nitrogen in the soil, they are a good companion for melons. By doing so, melons can take up more nutrients from the soil, which benefits them.

Pole beans aren’t a good choice since they are taller and block sunlight from melons. Beans should not be planted near allium plants because they aren’t good garden friends. Alliums include onions, garlic, shallots, and leeks.


Basil, oregano, mint, and tansy are perfect companion plants for cantaloupe. Aside from repelling pests, herbs are also fragrant, keeping unwanted insects away. Because they grow compactly, herbs do not shade cantaloupe vines.

It is essential to plant some herbs in containers if you don’t want them to become invasive. Catnip and mint, for example, are invasive herbs.

Lettuce and spinach

Companion planting lettuce and spinach with melons is a great idea. They’re fast-maturing cool-season crops that will be harvested when the vining cantaloupe takes over.

These salad greens are a great addition to any meal and are even better when paired with a juicy chunk of cantaloupe. These salad greens will help keep the area around the melons weed-free and provide some shade in the hotter parts of the day.


If you’re looking for an easy way to keep aphids away from your melons, consider planting nasturtiums nearby. Nasturtiums are a great trap crop for aphids, as their peppery-scented leaves attract aphids away from your fruit crop.

So if you’re looking for a way to keep aphids under control while adding color and biodiversity to your garden, consider planting nasturtiums near your melons.


Radishes are a great companion plant for melons because they help to suppress weeds and offer some protection from pests. Melon plants can benefit from the fast-growing, fast-maturing nature of radishes, which allows them to take over quickly and provide ground cover.

Radishes can also be harvested before the melon plants need that space, providing an additional food source.

Radish leaves attract aphids, an easy meal for predatory insects like ladybugs and lacewings. 

Wild Flowers

When it comes to companion planting for melons, wildflowers are a great choice! They bring pollinators that will help your melons pollinate, set fruit, and look beautiful in the garden.

If you’re growing your melons in containers, you can plant the wildflowers in the same container or separate containers nearby. Just be sure to place them near your melon patch so the pollinators can easily find them.

Wildflowers make great companion plants for melons because they’re easy to grow and don’t require much care. They also come in various colors, so you can choose one that will complement your other plants.

If you’re looking for a way to improve your yield and harvest, consider adding some wildflowers to your garden!
