Spaghetti Squash
Cucurbita pepo 'Spaghetti'
vegetableSpaghetti squash is a winter squash whose cooked flesh pulls apart into tender, pasta-like strands, mild in flavor and low in calories, which makes it a popular noodle substitute. The vigorous vines produce oblong, hard-shelled, golden-yellow fruit that cure and store for months.

🌱 Growing Guide
Direct sow after the last frost once the soil is consistently above 60F, in full sun and rich, well-drained soil. Give the long vines plenty of room, water deeply and evenly, and mulch to hold moisture; winter squash needs a long, warm season to mature fully.

🌾 Harvest & storage
Harvest when the rind turns deep golden-yellow and is hard enough to resist a fingernail and the stem is dry and corky, cutting the fruit with a few inches of stem attached. Cure at 80 to 85F for about 10 days to harden the rind, then store at 50 to 60F, where it keeps for one to three months.
🥗 Nutrition & benefits
