Squash, Winter
Cucurbita spp.
Winter squash matures hard-shelled fruit for storage on long vines through a warm season of about 80–120 days from sowing. Full ripening on the vine plus curing for suitable types improves keeping quality compared with picking immature fruit. Large spacing and full sun with eight hours of direct light support sugar development.
Plant family Cucurbitaceae · Also called butternut squash, acorn squash

Start vines after frost has passed.
Direct sow 2.5 cm deep two to four weeks after the last frost, with optional indoor start 3–4 weeks before frost. Germination is 4–10 days.
Tender plants need frost-free growth. Large vines compete for space; one or two well-pollinated plants can supply a household.

Reserve ground for long runners.
Match pumpkin spacing at 90–150 cm between plants and 180 cm rows. Vining habit and fruit size drive large space need.
Containers list 45 cm depth and 75 litres minimum for trial plantings of compact types.

Allow for the mature form of the selected variety.
Install support early when it is required or useful.
Maintain moisture through fruit swell.
Eight hours of direct sun supports sugar development in fruit. Shade reduces both yield and storage potential.
High water at 35–50 mm weekly during growth with pH 6.0–7.0. Taper stress near harvest only after fruit has sized, unlike watermelon where late drought is sometimes debated.
Sunlight
Full sun preferred (8+ direct-sun hours/day)
Soil pH
A suitable acidity range for general growth.
Weekly water
High water need.
Keep soil consistently moist but not waterlogged, especially during establishment and harvest development.
Cure mature fruit before storage.
The 80–120 day range begins at sowing. Harvest when rind resists fingernail pressure and stems are dry.
The key tip recommends full vine maturity and curing before storage. Immature fruit rots quickly in the pantry.
