🌼 Companion Plants That Repel Cucumber Pests

Primary keywords: pest-repelling plants for cucumbers, natural cucumber pest control
Long-tail keywords: what to plant with cucumbers to keep bugs away

Cucumber plants are vulnerable to a range of pests—aphids, cucumber beetles, spider mites, and squash bugs, to name a few. Luckily, several aromatic and flowering plants act as natural repellents, keeping these troublemakers at bay.

1. 🌿 Nasturtiums

Nasturtiums are more than just pretty flowers. Their peppery scent repels aphids, whiteflies, and cucumber beetles, making them a top choice for natural pest control.

Bonus: They’re edible and attract pollinators—making them doubly useful.

2. 🌼 Marigolds

Marigolds release compounds in their roots and foliage that deter nematodes and insects like aphids and beetles. Their bright blooms also attract predatory insects such as ladybugs and lacewings.

Pro Tip: Plant marigolds around the perimeter of your cucumber bed for a fragrant pest-repelling border.

3. 🧄 Garlic

Garlic’s strong aroma confuses and deters many insect pests. It’s particularly effective against aphids and spider mites, two common cucumber nuisances.

Tip for small gardens: Interplant garlic cloves between cucumber vines for space-saving protection.

🌱 Companion Plants That Improve Cucumber Yields

Long-tail keywords: how to grow more cucumbers naturally, plants that help cucumbers grow

Beyond pest control, some plants actively support cucumber growth by improving pollination, enhancing soil health, or offering shade and structure. These allies help your cucumbers grow bigger, healthier, and more flavorful.

4. 🌿 Basil

Basil is a multi-tasking herb that not only deters insects like thrips and flies, but also improves the growth and flavor of cucumbers. Its fragrant oils are known to benefit nearby plants and attract pollinators.

Plus: Fresh basil and cucumber are delicious together—straight from the garden to the kitchen.

5. 🌽 Corn

Corn and cucumbers make great companions thanks to their complementary growing habits. Corn grows tall, providing dappled shade and natural support for cucumber vines that tend to sprawl.

Garden layout tip: Train cucumber vines to climb corn stalks to maximize vertical space.

6. 🌸 Borage

Borage is a lesser-known gem in the garden. It improves cucumber health by attracting bees and other beneficial pollinators while deterring harmful pests like tomato hornworms and cabbage worms.

Borage bonus: It adds trace minerals to the soil and is edible too!
