Marigolds can benefit tomato plants by repelling pests, attracting beneficial insects like ladybugs and parasitic wasps, and even helping to control root-knot nematodes.
Here’s a more detailed look at the benefits:
Pest Repellent:
Marigolds have a strong scent that many tomato pests find unappealing, including aphids, whiteflies, thrips, and even some rabbits.
Attract Beneficial Insects:
Marigolds attract ladybugs, parasitic wasps, and lacewings, which help control tomato pests like aphids and tomato hornworms.
Trap Cropping:
Marigolds can act as a trap crop, attracting nematodes to their roots instead of the tomato plants.
Improve Soil Health:
Marigolds help improve soil health by adding organic matter and nutrients as they decompose.
