Companion Planting: Cabbage.

Plants that assist each other to grow well, repel insects or even other plants when grown next to each other is called companion planting and can be a sustainable and eco-friendly way to improve and protect your garden against unwanted pests and disease.


All members of the cabbage family do well planted with aromatic herbs such as celery, dill, camomile, sage, mints and rosemary. Hyssop, thyme, wormwood and southernwood help to repel the white cabbage butterfly which lays eggs that turn into cabbage worms.

Do not plant members of the cabbage family with tomatoes, pole beans or strawberries. But they will do well with potatoes, beets and onions.

If cabbage or broccoli does not form good heads, it is a sign that lime, phosphorus or potash are needed in the soil.

Natural Insect and Disease Control: BT.

Bacillus Thuringiensis. Commonly referred to as BT.

BT is a selective bacterial disease effective against may insects such as the fruit leaf roller and various caterpillars, specifically tent caterpillars and other moths, the tobacco budworm, bollworm and cabbage loopers. The disease attacks the caterpillar in the larvae stage after they come out of their tent.

BT produces crystals during spore production that act as a stomach poison on insects eating the treated plants, but it is not toxic to plants, people or animals, and can be applied up to the day of harvest.

Plants that Benefit: Use on all members of the cabbage family that cabbage loopers just love to eat up. Fruit trees to stop tent and army caterpillars which in large infestation cycles can destroy whole orchards. Also good to use on lettuces and celery.
