Squash Planting Instructions
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.
Pests: Squash bug - Hand pick. Bury or compost plant residues after harvest.Squash vine borer - Remove by hand and destroy.
Striped cucumber beetles - Construct tents of fine netting or cheeesecloth or use floating row covers over young plants. Put in place at planting and remove at flowering. Control of beetles may be a factor in preventing bacteria wilt
Diseases: Bacterial wilt (Erwinia tracheiphila ) -
Remove and destroy infested plants. If striped or spotted cucumber beetles appear control as soon as possible.Powdery mildew - Avoid wetting foliage if possible. Water early in the day so that aboveground parts will dry as quickly as possible. Avoid crowding plants and eliminate weeds around plants and garden area to improve air circulation.
Scab - Avoid wetting foliage if possible. Water early in the day so that aboveground parts will dry as quickly as possible. Avoid crowding plants and eliminate weeds around plants and garden area to improve air circulation.
Viral disease - Remove and destroy entire infested plant along with immediately surrounding soil and soil clinging to roots. Eliminate wild cucumber and milkweed nearby. Plant variety Multipik to mask symptons on fruit. Control aphids early in the season by washing off with water as needed early in the day. A hard stream of water can be used to remove many aphids.
