Companion planting is a way of planting in which you inter-plant different varieties of plants to enhance growth or aid in pest control. Companion planting is based on years of experience passed down through the generations and some scientific studies
Over all, companion planting is simply about plants helping each other- to grow better, to fend off pest and to taste better. Some plants do better when planted with a certain type of neighbor, and some should not be placed in close proximity to each other. How can companion planting help you fight your garden pests? Here’s a list of 16 ways to get the most out of your companion planting pest control.
16 Ways to Use Companion Planting to Control Pests
1. If your beans are struggling with Mexican Bean Larvae, try mixing in some marigold plants in your rows. Marigolds can help with a number of pests including cabbage worms and aphids. Sprinkle them throughout your garden!
2. Interplant celery with your cauliflower to help repel the white cabbage butterfly.
3. Planting cucumber with your corn is mutually beneficial. The cucumber plants will help keep the racoons off of your corn, while the corn will help reduce wilt in your cucumbers.
4. Plant radishes in your cucumber hills- just a couple- and leave them there all season. This will help protect your cucumbers against cucumber beetles. This also works with squash and melons that are attacked by the striped cucumber beetle.
5. Growing beans among your eggplant will help repel the Colorado potato beetle.
6. Mix parsley into your carrot rows to help repel the carrot fly.
7. Grow nasturtiums with your squash to help keep that dreaded squash bug away.
