Companion Plants for Spaghetti Squash

Squash is a family that includes different varieties of this vegetable. Regardless of the type you plant in your garden, you’ll notice they require much space and plenty of nutrients to grow.

Spaghetti squash is no exception. To increase your chances of success with companion planting, you must always pair species with opposite traits. Because spaghetti squash is a heavy feeder, you should plant it next to a species that can thrive with little nutrients without depriving your colorful vegetables of what they need.

Because of its growth patterns, squash will contribute to keeping weeds at bay. Plus, it will protect other plants from strong sunlight and maintain moisture in the soil.

Companion Plants for Spaghetti Squash

The ultimate companion plants to spaghetti squash are beans and corn. Indeed, these plants have been planted together for centuries and with excellent results. The indigenous people referred to this trio as “the three sisters.”

Beans are nitrogen-fixing plants that add more of this nutrient to the soil for the benefit of your spaghetti squash, which needs plenty of nutrition to grow. Corn can shade your squashes from the harsh sunlight of the summer months and protect them from strong winds.

Plus, they provide your vining plants with an attractive structure to grow on. Your spaghetti squash prevents the formation of weeds and deters pests (like rodents) from snacking on your corn.

Because beans, corns, and squash have similar moisture requirements, you won’t have to struggle when taking care of them.

Nasturtiums and Marigolds

If you prefer adding flowers next to your vegetables, consider adding nasturtiums or marigolds.

Herbs make for excellent companion plants to your spaghetti squash. They release strong scents that keep most insects away from them (and their neighbors). Plus, during the blooming season, they attract plenty of beneficial pollinators, which will increase the yields of your harvest. Consider adding plants such as peppermint, dill, oregano, parsley, and lemon balm.

But don’t forget to make sure you choose a species that grows well in your hardiness zone. Also, keep in mind that herbs with strong scents might alter the taste of your spaghetti squash. Luckily, most of the time, the change is slight.

Cool Season Crops

Squash needs plenty of space to grow. You can plant it next to cool-season crops such as beets and radishes to use such spread to your advantage. The lush foliage of your spaghetti squash might create enough shade to grow plants that don’t like exposure to the direct sun successfully.

Companion Plants for Spaghetti Squash: Conclusion

While most plants grow well next to spaghetti squash, avoid adding potatoes, tomatoes, or cucumber next to these vegetables: they will compete for nutrients and halt your squash’s growth.
