Summer Squash Planting Information:

Summer Squash need warm weather to grow. The plants produce squash in 50 to 65 days, so there is no point in planting them indoors. It is best to plant seeds directly in the garden. Plant your seeds after the soil has warmed up. Thin so there are 4 plants per hill. Summer Squash produces abundantly, so there is no need to plant successive plantings. Eight plants will provide more than enough for a large family. You can trellis squash to save space. Plants grow 2 ft tall, and vines spread up to 10 ft.

Soil Requirements:

Requires fertile, slightly acid soil in a well-drained location in the garden. Apply mulch, grass clippings, or straw around the base of the plant. Add well-composted manure.

Water Requirements:

Keep soil consistently moist, but not waterlogged. Water well during dry and hot spells.

Fertilizer Requirements:

Use Slow Release (6 Month) Fertilizer when transplanting outdoors. Apply Miracle-Gro Liquid Fertilizer every two weeks.

Harvest Tips:

Protect ripening summer squash from damp ground by placing them on boards. Cut summer squash carefully from plants to prevent damaging the vines.
