Companion Vegetable Planting

Companion Vegetable Planting

Long-time gardeners use Companion Vegetable Planting to ensure a healthy garden. Did you know tomatoes and basil do great together in your garden and the cooking pot? Many herbs are natural insect repellents that help keep your garden bug-free and reduce or eliminate the need for potentially harmful pesticides. By using a companion planting technique, many gardeners discover they can discourage garden pests without harming helpful insects such as ladybugs and bees. Some herbs, through their odors or root secretions, will deter pests naturally. A bonus is fragrant herbs that will season the fruits of your labors. Please note that herbs can grow huge! They will take over your garden if not trimmed from time to time.
