Companion planting is a very natural concept. If you look out in the wild, you never see one form of plant by its lonesome. Daisies, black-eyed Susans, clover, and buttercups amongst others interweave into these communities of flowers. Maples, ash, willow, and pine mingle through the woods, rarely sanding aloof from one another. The plants that you do see by themselves look alone, deprived, and normally have a harder go at it than those mixed into a society of flora and fauna. Companion planting takes this idea that plants should not be segregated from one another and works towards growing plants with one another in a helpful, semi-self-sustainable type of gardening.
We’ve used companion planting – to a different degree each year – in all of our gardens. Sometimes companion planting works out well, other times, not so much. For example, it’s been a few years, but we did try a three Sister’s Garden of pumpkins, corn, and beans together. We didn’t have much luck that time, but I’m wondering if it was mostly “user error” as I didn’t look into the length of the growing season that the variety of corn I picked needed. (In Maine we have a very short growing season, so this is something to take into consideration.) I’m debating about trying the Three Sister’s Garden again this year now that I’ve had more time to reflect on what went wrong with that previous attempt.
Many people who now have gardens from our generation don’t know about the idea of companion planting simply because they grew up off from their parents and grandparents victory-style gardens that were popular starting in WWII. These gardens were functional and yet very carefully sculpted to fit the post-card time era that they were in. Companion planting went by the wayside at this time, but is now beginning to make a resurgence, specifically for those of us that have limited land space and prefer to do things without chemical fertilizers and pesticides.
Below is a chart that I made for a post a few years ago talking about companion planting. It’s very basic and only includes the basic gardening selections, but it gives a great starting point for those new to the practice!
|What we’re planting…||What they can be companions with…|
