Cucurbita pepo 'Early Prolific Straightneck'
vegetableA compact yellow summer squash producing straight-necked cylindrical fruits identical in flavor to yellow crookneck but without the curved neck, making them easier to slice uniformly.

When to Fertilize
At planting with compost; side-dress balanced fertilizer when plants start vining
Fertilizer
Balanced 10-10-10 or compost; avoid excess nitrogen which favors leaves
Direct sow after last frost when soil is above 65 F, or transplant 3-week-old starts. Plants are large and bushy — space 24 to 36 inches. Pick every 2 to 3 days to keep plants producing. Overripe squash signals the plant to slow fruit production and the flesh becomes fibrous and seedy. Hand-pollinate in the morning if fruit sets poorly. Very productive from midsummer through frost.

Proactive ways to stop trouble before it starts — tap a name with an arrow for its full guide
Plant after mid-June in the North; Bt injection into stem; row cover fabric wrapped at stem base
Handpick adults and bronze egg clusters from leaf undersides; kaolin clay spray
Increase spacing; remove affected lower leaves; neem oil at first sign
Row cover on seedlings; beneficial nematodes; yellow sticky traps
Best at 6 to 7 inches with smooth, glossy yellow skin. Skin should be tender enough to nick with a fingernail. Older fruits over 10 inches have tougher skin and large seeds. Harvest daily in peak summer. Share the abundance with neighbors — production can overwhelm even enthusiastic eaters. Store at room temperature 2 to 3 days or refrigerate up to 5 days.
Low in calories, good source of vitamin C, B6, potassium, and manganese. Yellow skin provides lutein and zeaxanthin carotenoids for eye health. High water content keeps you hydrated in summer heat.
