Prof. Samuel Fitzgerald, Ph.D.Grasping companion planting helps you to get the maximum out of your pumpkins by competing with them or perhaps introducing disease into the mix. Then some plants benefit them, saving hours on maintenance or increasing yields. I redesigned my garden after those beanstalk potato plants left my pumpkins in video game style, going nowhere! Your clever combinations help my harvests and cut down on hours of work.
Harmful Neighbors
- Potatoes compete for nutrients aggressively
- Fennel releases growth-inhibiting chemicals
- Other cucurbits increase disease vulnerability
Beneficial Allies
- Corn provides natural vertical support
- Beans enrich soil with nitrogen fixation
- Radishes deter destructive cucumber beetles
Pest Control
- Marigolds repel root-knot nematodes
- Nasturtiums attract aphids away from vines
- Borage deters tomato hornworms
You can create border defenses using patches of pumpkins, marigolds, and nasturtiums. Flowers like these are repellents to nematodes and beetles. I plant them in close-set rings two feet from the vines, and their presence makes much less use of the chemical available, for my enemies are kept away. Companions always change places yearly.
Maximize mutual benefits when growing pumpkins by planting them amidst corn and beans. Corn stalks will twine up the vines while the beans contribute nitrogen to nourish your pumpkins. I interplant in hills 4 feet apart. Your plants are forming beneficial societies, improving one another while enriching the soil.
Avoid cucurbit grouping with zucchini or squash in the vicinity. All these cousins are susceptible to diseases, including powdery mildew. I try to maintain a 20-foot buffer between the cucurbit families. Your disease prevention touches us all. It's essential to record the location of each crop you plant each year, so you can refer to it when making planting decisions for the next year.
