As I write this, it is August – the weather is hot, and most of the country is officially in a state of drought – but this won’t last forever. Take heart, and start planning your next garden, whether it is a fall garden, or next spring’s garden – the time to begin thinking about it is now. A little pre-planning for companion planting can mean the difference between a so-so harvest and lush, vibrant plantings that benefit each other.
Paired Planting to Prevent Pests
By placing some plants near each other they can actually help with pests – the dill plant repels the tomato moth, for example, and if your plants are being harassed by cabbage moths, plant them with rosemary, dill, mint, sage, oregano, or nasturtiums to repel these pesky pests. Check out this list for lots of plants you can pair together to get rid of the nasty bugs that hurt your precious veggies, while encouraging the good insects that pollinate and help them grow.

The Internet and your friendly agricultural extension agent can help you in identifying the pests. Once identified, you can attack the pest naturally and safely with companion plantings – and forget about dangerous chemical concoctions sprayed on your family’s food supply!
Companion planting is easy and very effective, so plan away for that next garden whether it is this fall or next spring.
