Squash has many good neighbors in the vegetable garden, receiving help from a wide range of other vegetable plants as well as herbs and flowers. There are only a few plants that should not be grown alongside it.
Potato is not a friend of squash, and squash is positively a sworn enemy of potato! Planted together, they stunt one another’s growth. And because squash attracts insects that can infest the potato plant, blight is a real possibility when these two get together.
Cucumbers and Melons of Yore
If you had a vegetable garden last year, try not to plant your squash in the same place occupied last year by the cukes and melons. These three types of veggies all attract the same predatory insects, and you may be harboring some pests in the soil and surrounding area left over from last season. They will fall upon the squash with delight! If possible, site your squash elsewhere.
Although it is the Fourth Sister
in the Native American Three Sisters planting, sunflower is really a frenemy to squash. Not everyone agrees about this, but many gardeners believe that sunflower is a ruthless competitor for soil nutrients, and that it can reduce the yields of the squash patch simply by being planted in or near it. When squash and sunflowers compete, sunflowers win. So if you want a big squash yield, think about distancing the Fourth Sister!
These are the only real foes to squash, so you should plant a large crop of your favorite crooknecks, zucchinis, pattypans, and all the winter varieties. Squash is a great presence in the sunny garden, and a friend to nearly all!
