Companion Gardening: Strategically Planning your Garden for Greatest Effect
Age old garden wisdom, over the expanse of time, has shown us that crops and other vegetation thrive when paired with particular plants but struggle greatly when paired with others. Black walnut trees are a great example of this. If you plant tomato plants near your black walnut tree, you will see your plants first begin to yellow, then wilt, and finally die before producing a single fruit. This is due to the substance called juglone that is released by the roots of the black walnut tree that damages the tomato plant.
While some plants are harmful to their neighbors, others when planted together actually help each other. Blueberries and thimbleberries, for example, love to be near pine trees because of the acidic soil pines create. Garlic not only has the neat quality of helping herbs produce their essential oils, it also deters garden pests much like the Japanese beetle. Insect repellent is the other benefit to companion gardening. Many plants such as garlic, mint, basil, and onion repel insects naturally. Marigolds are the queen of insect repellant and so planting it liberally throughout your garden would be highly beneficial. With a little strategic planning, you can decrease damage from insects while simultaneously creating a synergistic cooperative growth within your bountiful vegetable garden.
Use this chart to help you in planning your garden this spring and to choose how to group your plants for best results.
