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
• Seed Form: Raw, unpelleted seed; sale form does not confirm chemical-treatment status
• Active Pack Sizes: 10 g raw seed, 100 g raw seed, 500 g raw seed
• 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: None; sow dry unless the delivered lot label says otherwise
• Method: Warm direct sow preferred; transplant only a young intact plug before it becomes root-bound
• Sow Depth: 5 mm under the exact current Ubuntuberg label; keep the shallow cover continuously moist. The separate Starke Ayres Chicago Warted guidance uses 20 mm.
• Germination: 7–14 days at a 21–30°C seed-zone target; do not direct sow below 18°C
• Final Spacing: The current label says 50 × 150 cm, but KZN guidance gives 50 cm between plants and 200–270 cm between rows for Hubbards; use the wider final spacing for this long vine.
• Harvest: Expect about 100–120 days, with 110 days on the exact Starke Ayres cultivar page. The current stocked label's 90–120 days is retained as the outside planning window.

Why Grow This Variety

• Large deeply warted dark-green fruit is the exact Chicago Warted Hubbard outcome.
• Golden-yellow flesh suits roasting, soups, stews and baking.
• A hard mature rind permits curing and short-term storage.
• The exact module corrects the live page's C. pepo identification to C. maxima.

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.
• Use the KZN Hubbard row spacing rather than treating 150 cm as enough space for the whole vine.
• 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: Raw seed is the unpelleted sale form, not proof of untreated seed. Do not eat seed or use it for feed, sprouts or microgreens; follow the delivered lot label.
