Summer squash is a generic term that refers to several varieties of squash that are typically grown and eaten (as opposed to stored over winter) during the summer months. Some of the most common summer squash include the zucchini, Patty Pan, and crook-neck squashes.
If there was ever a seed you could pop in the ground and watch grow in no time; its the summer squash. Well, you do have to water it but even feeding is optional if you have good soil. If you are a single person or family of less that 4 you can get along with 1 to 2 plants maximum. Zucchini is the most prolific and easy to grow variety.
Buy seed at your local nursery. Once you grow them you can let one squash mature and save the seeds for the next year. Plant the seeds in the garden in early spring when the soil warms during the day. Plant at least 2 -3 eds on a slightly mounded hill. Water to keep moist until it germinates, typically in about 5-10 days. Thin the small plants down to the strongest one once they are about 2" high.
The summer squash plant just needs moderate water and full sun. Of course feeding never hurts. The plant will produce both male and female flowers. Pollination depends on insects visiting both a male and female flower to produce the fruit. Sometimes early on I'll hand pollinate the flower by simply using a Q-TIP to rub the pollen from the male flower then rubbing the female flower with the Q-TIP. Later on as the plant matures it should produce enough flowers and attract enough insects to keep you in more squash than you can handle.
