Great news: Spring vegetable gardens are just around the corner. If you found yourself battling harmful insects last time you got your green thumb on, don’t reach for chemical insecticides just yet. Instead, plant smarter by choosing the right types of vegetables to group together. Did you know tomatoes repel caterpillars that chew on cabbage leaves? Or onions, with their pungent taste and smell, repel most pests? And radishes attract leaf miner insects to the leafy greens on top, but the insects have no effect on the actual radish itself underground? By adding onions, radishes and tomatoes, you can create a natural insect barrier to help your garden thrive.
