Squash plants have both male and female flowers on a single plant. You can tell the difference because the female flowers have a small bulb at the base of the bud that will become the fruit. Male flowers usually appear first. Bees are needed to pollinate the female flowers with male pollen for the fruit to form.

As soon as the soil can be worked in the spring mix plenty of organic matter into the soil along with well composted manure to create a loose, nutrient rich medium. Add an organic all-purpose fertilizer at the time of planting.

Transplanting

Most garden centers will have squash seedlings for sale in early May. Take care to not disturb the roots any more than necessary while transplanting. Put a small amount of organic all purpose fertilizer next to the hole and mix with the soil so that the roots don’t touch the fertilizer. Place plants to the basal roots and firm soil around the plant to hold it upright.

Seed

Seeds can be started indoors 4-6 weeks before the expected last frost. Since they grow fast you can also sow the seeds directly into the garden in late May and still have plenty of production. Plant seeds 1 inch deep and lightly firm soil over them. Water thoroughly and keep surface moist until seedlings emerge.

MULCHING

Mulch around the plants once they are well established.

WATERING

Squash tend to wilt slightly in the hot sun but doesn’t necessarily mean they need more water. They appreciate a bit of afternoon shade. Placing the plants on the east side of the garden with taller plants on the west, can sometimes do the trick. Keep the soil moist, but don’t over water.

FERTILIZING

Squash are heavy feeders so add plenty of rich compost to the seed bed and feed with side dressings of an organic all-purpose fertilizer throughout the growing season.

Squash plants tend to have large leaves that shade the ground around them, so weeds may not be a problem. A good mulch will also cut down on weed growth.

The most common diseases on squash are bacterial wilt, downy mildew, powdery mildew, scab, and mosaic.

PRESERVING/STORING

Squash is very versatile in the kitchen. It can be boiled, fried, baked, and stuffed; it is great in soups, stews casseroles, etc. Squash can be canned, dried, or frozen or pickled.
