Companion planting is a small-scale method of intercropping, which refers to the practice of planting one kind of plant next to another or others that help it thrive. It is often associated with small-scale organic gardening (the type of gardening I have exclusively done for the past 18 years) or other biodynamic planting methods, and it is a favorite technique of farmers seeking to produce more yield in less space.
Although popular literature touts the benefits of intercropping over monocropping, there is a lot of debate, and consequently, confusion over which plants go well together, and whether some of the reported benefits of companion planting are consistent or coincidental. This is partly a debate between using scientific methods (usually in controlled, laboratory stings) and using personal experience to determine how to companion plant. There are benefits to both methods, though admittedly, I prefer to rely mostly on experience (my own and that of successful gardeners I know) with a smattering of science to help me understand why certain combinations have seemed to work well in my own garden, while others don’t seem to have much effect one way or another.Read More
