Gardeners, did you know your vegetable patch could be a thriving ecosystem of natural pest control? By planting certain companion plants, you can keep pests away from your vegetables. These plants work together to create a bug-free garden. Let's explore the secrets to a pest-free vegetable garden.
The Benefits of Companion Planting
Companion planting brings many benefits to the vegetable garden. It's better than using trap crops for most gardeners. Desirable repellent plants, often herbs, help reduce pests without taking up too much space.
These plants keep insects away, draw in helpful bugs, improve soil, and make vegetables grow better. For instance, rue near roses attracts ladybugs that eat aphids. Sage near broccoli and kale keeps white cabbage moths away.
Planting bright yellow flowers away from veggies can lure squash bugs away. Beneficial nematodes kill young bugs like flea beetles and squash bugs. You can buy praying mantis or ladybugs to protect your plants.

In summary, companion planting fights pests, attracts good bugs, and makes soil better. It makes gardens more resilient and productive.
