Summer squash comes in a variety of shapes and colors. Bush varieties take up relatively little space, and if kept picked will keep producing right up to frost.

Growing Guide
GROWING NOTES
Prefers well-drained, fertile, loose soil, high in organic matter with pH between 5.8 and 6.8. Plentiful and consistent moisture is needed from the time plants emerge until fruits begin to fill out.

Tender annual

Most summer squash grow on compact vines, in contrast to the sprawling vines of most winter squash and pumpkins.

Some varieties have interesting "water marks" on their foliage.

Most summer squash varieties form a compact, bushy vine.

MAINTAINING
Squash like warm soil and are very sensitive to frost. So don’t be in a rush to plant early in spring. Wait until danger of frost has passed and soil has warmed to about 70 F, or about 2 weeks after the last frost date.

Direct seed ½ to 1 inch deep into hills (which warm and drain earlier in the season) or rows. Sow 4 to 5 seeds per hill. Space hills 3 to 4 feet apart. When the plants are 2 to 3 inches tall, thin to 2 to 3 plants per hill by snipping off unwanted plants without disturbing the roots of the remaining ones. In rows, sow seeds 4 inches apart in rows 4 to 5 feet apart. Snip off plants to thin to one plant every 12 to 24 inches.

For extra early crops, start inside in 2- to 3-inch pots or cells 3 to 4 weeks before transplanting outside. Sow 3 or 4 seeds per pot and thin to one or two plants by snipping off the weaker plants to avoid damaging the roots of those that remain. Harden off by cutting back on water and reducing temperature before transplanting. Plant transplants out in the garden about 1 to 2 feet apart after all danger of frost has passed.

To hasten first harvest by as much as 2 weeks, use black plastic mulch to warm soil before direct seeding or transplanting. Early fruits are sometimes wrinkled, turn black or rot due to poor pollination.

At the end of the season, remove or till in vines to reduce mildew. Use row covers to protect plants early in the season and to prevent insect problems. Remove cover before flowering to allow pollination by insects or when hot weather arrives.

Mulching plants helps retain moisture and suppress weeds. Mounding soil around the base of the plants can discourage squash borers from laying eggs.
