Cucurbita spp. In the diverse family of squash are true nutritional powerhouses, encompassing a wide array of forms, flavors, colorations, and culinary applications. Squash are rich in the carotenoids necessary for vitamin A production and boast a wide complement of amino acids. While starchy, most of the carbohydrates in the fruit come from special polysaccharides, pectins, which have exhibited strong antioxidant, anti-inflammatory, and anti-diabetic, insulin-regulating properties.
Days to maturity are from date of direct seeding.
Culture
• Fertile, well-drained soil gives best results
• Squash is a warm season crop, avoid planting too early; raised beds and plastic mulch help keep roots warm
• Squash are monoecious (bearing separate male and female flowers on the same plant) and require insect pollination
• Poor fruit set is often the result of inadequate pollination; plant bee attractant flowers
Direct Sowing
• Plant after frost danger when soil warms to 65°F
• Work in shovelful of compost and 1/2 cup TSC's Complete fertilizer into hill
• Keep soil evenly moist but not wet as too much moisture causes seed to rot
• Bush varieties: sow 3-4 feet apart
• Vining varieties: sow 4-6 feet apart
Transplanting
• Start indoors 3-4 weeks prior to anticipated transplant date in 4 inch pots
• Work in shovelful of compost and 1/2 cup TSC's Complete fertilizer into hill
• Transplant carefully as to not disturb roots
Insects & Diseases
• Common insects: Spotted and striped cucumber beetles, vine borers and squash bugs
• Insect control: Row covers and/or apply Pyrethrin
• Moschata species are resistant to vine borer
• Common diseases: See chart below; diseases vary by region
• Disease prevention: 3-4 year crop rotation, and fungicide applications
Harvest & Storage
• Summer squash: Harvest regularly when fruits are young to keep plants productive
• Winter squash: Leave on vine until fully mature, rinds should be firm
• When winter squash is mature cut stem leaving 2-4 inches remaining, gently wash in sanitizing solution; 10 parts water to 1 part bleach
• For best results move winter squash to a warm dry area 80-90°F to cure; see each type (below) for curing requirements
• Store winter squash at 50-60°F with 50-75% relative humidity and good air circulation
