Summer squash comes in a variety of colors, like these yellow straight-neck squash and green zucchini.
Looking for something new and delicious to grow in your kitchen garden this year? Give summer squash (Cucurbita pepo) a whirl. This delicate and tasty treat is easy to grow in a well-prepared garden. And because it comes in a variety of colors and shapes, this veggie packs some visual interest to your garden, too!

Never tried summer squash? You actually probably have and didn’t even realize it. Zucchini is just one type of summer squash. This long, green beauty is popular because its plant produces a lot of vegetables, making any beginning gardener feel successful. Yellow squash is another type, but it’s got a bit more of a delicate taste. This veggie can be long and straight like a zucchini or have a curved, swanlike neck. Another variety that’s gained popularity is the patty pan squash. Shaped like a 1950s flying saucer, this veggie has a subtle taste and is often both yellow and green.

One of the best things about summer squash is that it grows very quickly – no matter what type you pick. Seeds can be sown directly into the ground, or you can start them early in pots. Just know that they’re very sensitive to frost, so be sure that the last freeze has passed before moving or planting them outside. If the forecast calls for an unexpected late frost, cover your plants with clay pots or frost-protection fabric to keep them safe and healthy.

Plant your squash seeds about 1 inch deep and water them well. Be sure to cover the area with a floating fabric to protect sprouting plants from various insects. When the plants start blooming (in about a month), uncover them to allow pollinators to fertilize the flowers. Harvest your squash while they’re still small to get the best-tasting, most-tender vegetables. (These plants quickly produce a lot, so you won’t run out anytime soon!)

To keep your summer squash plants producing all season long, protect them from predatory insects – especially the red, wasplike squash borer. This pest lays its eggs at the base of the squash plant. Once they hatch, young squash borers move into the plant and destroy it from the inside.

Tips
  • It’s a good idea to amend your garden soil before you plant. Whether you dig down into the soil or build a raised bed, ensure that what you’re planting in is loose and amended at least 12 inches deep with compost and organic fertilizer. Not only will this provide good nutrients, it’ll make it easy for roots to grow quickly.
  • When selecting a squash variety, consider how much space you have, as well as what fruit you want to eat. Some squash plants, like zucchini, are bush plants that need an area about 3 feet wide for each plant. Other varieties are vines and are planted in groups or hills. These can be grown vertically on structures (like you’d grow peas or beans) to maximize garden space.
Faqs
  • Q: Can you save the seeds from squash plants to grow next year?
    A: If you decide to save squash seeds for next year, be aware that many squash varieties are hybrids, and their seeds may not produce plants with the same tasty fruit. Because squash easily cross-pollinates with gourds, it’s important to hand-pollinate the squash flowers (and protect them from other pollen) if you want to produce seeds more likely to yield the same fruit.
