Quick Grow Facts
-
Plant Type: Warm-season edible squash
-
Variety: Green Hubbard Chicago Warted
-
Scientific Name: Cucurbita maxima
-
Outcome: Mature Hubbard squash; harvest when fully sized with a hard rind, then cure before short-term storage.
-
General Sowing Time: Use the earliest suitable warm slot because this is the longest, largest crop in the family. In cool districts sow September–November/December so fruit hardens before autumn frost.
-
Position: Full sun
-
Growth Form: Large vigorous trailing vine; grow on the ground with ample room. Do not trellis heavy mature fruit unless the structure and individual fruit slings are engineered for the load.
-
Pretreatment: No pretreatment needed; sow dry
-
Method: Warm direct sow preferred; transplant only a young intact plug before it becomes root-bound
-
Sow Depth: About 5 mm in warm, fine soil; keep this shallow cover evenly moist until emergence.
-
Germination: 7–14 days at a 21–30°C seed-zone target; do not direct sow below 18°C
-
Final Spacing: Allow about 50 cm between plants and 200–270 cm between rows so this long vine can spread.
-
Harvest: Allow roughly 90–120 days in suitable warmth, but harvest by a fully sized fruit and hard rind rather than a fixed date.
Why Grow This Variety
- Large, deeply warted dark-green fruit makes a striking mature storage squash.
- Golden-yellow flesh suits roasting, soups, stews and baking.
- A hard mature rind permits curing and short-term storage.
Garden Uses
Harvest fully mature fruit for roasting, soups, stews, purées and baking.
Growing Notes
- Direct sow is preferred and this long-season variety needs the earliest safe warm slot.
- Leave generous space for the long vine and keep developing fruit off persistently wet soil.
- Keep fruit on dry mulch or boards and protect exposed dark-green fruit from sunburn.
- Cut with a short stem; damaged, frosted or immature fruit will not store well.
Seed safety: Seed sold for sowing is not food. Do not eat it or use it for feed, sprouts or microgreens; choose seed explicitly supplied for edible sprouting if that is your goal.
