There are several well known varieties within C. pepo, including Zucchini, Acorn Squash, Delicata Squash, Spaghetti Squash, as well as many others.

C. pepo are summer squashes, and the main difference between summer and winter squashes are their uses. Summer squashes are generally harvested earlier in the season, and are eaten right off the vine. Their skin is often soft and edible, and in general (with the exception of some like the Delicata Squash) cannot be kept for winter storage and fresh eating.

Summer Squash belongs to the Cucurbita genus.

How to grow and keep Summer Squash happy

As with any squash variety, prevention of disease is the key to getting a good harvest. Squash are particularly susceptible to powdery mildew, a fungus which manifests itself as a white powdery-looking substance on the leaves. Left untreated, this can kill the entire plant.

Good methods for preventing powdery mildew are proper air circulation around the plant and providing cover via row covers during periods of excess rain. Keep the plants well spaced, and as an extra method of prevention, spray the leaves with a milk/water or baking soda/water/dish soap mixture. Baking soda and milk both have anti-fungal properties. Any leaves that are affected, trim off and burn.
