Using Trap Crops or Companion Planting
Using trap crops or companion planting is an organic way to draw beneficial insects and to keep the harmful bugs away from the plants you want to keep bug-free. We grow marigolds, garlic chives, and dill for this purpose. The Old Farmer’s Almanac has a terrific article on using trap crops. To read the article, click here.
Marigolds are not only a beautiful, colorful addition to your garden, but marigolds are also helpful in repelling certain pests while still attracting beneficial insects. We grow marigolds around our tomatoes, lettuces, and eggplants to protect against whiteflies, aphids, slugs, and snails.
To draw the slugs and snails away from your garden, we suggest planting marigolds and use some bait as a first line of defense. In our garden, we place pots of marigolds around our vegetables and herbs, then sprinkle a little slug and snail bait on the dirt. If you have a very bad slug and snail problem, you may see them on your marigolds. We suggest using a pair of chopsticks to pick off, then drop into a jar with salty water to destroy.
We have crackerjack marigold seedlings available for purchase. These grow 2-3 feet tall. The flowers are large with gracefully overlapping petals.
