Companion Plants for Delicata Squash

1. Beans

Beans are an excellent companion plant for delicata squash. They help fix nitrogen in the soil, which can improve the growth and yield of your squash plants. Additionally, beans have shallow root systems that won't compete with the deep roots of your squash plants. You can plant bush beans or pole beans alongside your delicata squash.

2. Corn

Corn is another good companion plant for delicata squash. Like beans, corn can help fix nitrogen in the soil. Additionally, the tall stalks of corn can provide shade for your squash plants during hot summer days. Just be sure to give your squash plants enough space so they don't get crowded out by the corn.

3. Radishes

Radishes are a great companion plant for delicata squash because they can help repel pests like squash bugs and cucumber beetles. Radishes also have shallow root systems that won't interfere with your squash plants. You can plant radishes directly in the soil around your squash plants.

4. Nasturtiums

Nasturtiums are a beautiful and beneficial companion plant for delicata squash. They can help repel pests like aphids, whiteflies, and squash bugs. Additionally, nasturtiums have edible leaves and flowers that you can use in salads or as a garnish.

5. Marigolds

Marigolds are another flower that can help repel pests from your delicata squash plants. They are particularly effective at keeping away nematodes, which can damage the roots of your squash plants. Plus, marigolds add a splash of color to your garden!

6. Herbs

Many herbs make excellent companion plants for delicata squash. For example, basil can help repel pests like thrips and whiteflies. Mint can help repel ants and flea beetles. And dill can attract beneficial insects like ladybugs and lacewings. You can plant herbs directly in the soil around your squash plants or in containers nearby.

Tips for Planting Companion Plants with Delicata Squash

While companion planting can help repel some pests, it's still important to use organic pest control methods to protect your delicata squash plants. This might include using insecticidal soap, neem oil, or other natural products.

To prevent soil-borne diseases and pests from building up in your garden over time, it's important to rotate your crops. This means planting different crops in different areas of your garden each year.
