Universal: companion planting pest management
Quick answer
companion planting pest management for Universal: Companion planting leverages natural chemical interactions between plants — some plants produce volatile compounds that repel insect pests, while others attract beneficial predatory insects. Catnip and tansy repel green peach aphids and squash bugs; marigolds repel a wide range of soil nematodes and some flying insects; radishes planted among cucumbers repel cucumber beetles. However, companion planting effects are often modest and should be considered one layer of an integrated pest management approach rather than a standalone solution.
Start here:
- 1. Catnip and tansy reportedly repel green peach aphids and squash bugs — plant near susceptible crops like tomatoes, squash, and cucumbers
- 2. Marigolds (Tagetes spp.) repel soil nematodes and some flying insects — interplant throughout vegetable gardens as a general pest deterrent

How to handle companion planting pest management on Universal
- 1
Catnip and tansy reportedly repel green peach aphids and squash bugs — plant near susceptible crops like tomatoes, squash, and cucumbers
- 2
Marigolds (Tagetes spp.) repel soil nematodes and some flying insects — interplant throughout vegetable gardens as a general pest deterrent
- 3
Radishes planted amid cucumbers and squash repel cucumber beetles, which also reduces spread of bacterial wilt disease these beetles transmit
- 4
Plant dill, fennel, yarrow, and buckwheat to attract beneficial insects (lacewings, hover flies, parasitic wasps, lady beetles) that prey on aphids and other pests
- 5
Garlic and chives repel aphids — interplant among susceptible vegetables
- 6
Plant tomatoes near brassicas (cabbage, broccoli) — tomatoes reputedly repel cabbage worms
- 7
Avoid planting brassicas near legumes — both attract similar pests; rotate crop families annually to prevent pest buildup
- 8
Plant nasturtiums as trap crops — they attract aphids away from main crops, drawing pests to a sacrifice planting at the garden edge
Keeping Universal on track
Research companion plant combinations before designing garden layout; plant in dense, diverse polycultures rather than monoculture rows; combine with other IPM methods (biological control, resistant varieties, cultural practices) for reliable pest management.
