Why Companion Planting Matters in September
Companion planting involves growing certain plants together to benefit each other. In September, as temperatures begin to cool and daylight decreases, selecting the right companions can protect your crops from pests, improve soil health, and support plant vigor. Proper companion planting can also extend the harvest season and reduce the need for chemical interventions.
Key Companion Plants for September Gardens
Marigolds
Marigolds are renowned for their pest-repelling properties. Plant them near tomatoes, peppers, and eggplants to deter nematodes and aphids. Their vibrant flowers also add visual appeal to your garden.
Basil
Basil is a natural companion for tomatoes, improving flavor and growth while repelling pests like thrips and mosquitoes. Plant basil alongside your tomato plants for a productive partnership.
Radishes
Radishes grow quickly and can be planted between slower-growing crops like carrots or parsnips. They help loosen the soil and can deter pests such as flea beetles.
