Highlights
Those four-inch handles aren't just a marketing feature; they transform pumpkin harvest from an awkward, back-straining affair into something genuinely manageable. The dark orange skin glows against green vines, and the fruit's medium-long shape packs substantial size without becoming unwieldy. Expect reliable, prolific production even in less-than-ideal seasons, thanks to hybrid vigor that keeps plants pushing forward through variable growing conditions.
Common Uses
Harvest Jack serves beautifully as a dual-purpose pumpkin. Its 22 to 28-pound size and sturdy handles make it excellent for fall decoration and display, while the flesh suits traditional pumpkin cooking: soups, roasted preparations, and baking. The manageable weight and good handle design ease both harvesting and the logistics of getting it from garden to kitchen or front porch.

Care Instructions
Start Indoors
Start seeds indoors 3 to 4 weeks before your last spring frost date. Sow seeds in warm soil (70 to 85 degrees Fahrenheit) and keep consistently moist until germination. Transplant seedlings outdoors only after soil has warmed and frost danger has completely passed.
Transplant Outdoors
Transplant hardened-off seedlings into full sun when soil temperature reaches at least 70 degrees Fahrenheit and nighttime temperatures stay above 50 degrees. Space plants 36 inches apart. Harden off seedlings over 7 to 10 days by gradually exposing them to outdoor conditions before final transplanting.
Direct Sow
Direct sow seeds 1 to 2 inches deep after all frost danger has passed and soil temperatures reach 70 degrees Fahrenheit or higher. Plant seeds in mounds or rows spaced 36 inches apart. Thin seedlings to one plant per location once true leaves appear.
Harvesting
Harvest Harvest Jack pumpkins when the skin has developed a deep, fully dark orange color and feels hard when you press your thumbnail against it; the skin should resist puncturing. Cut the stem with a sharp knife rather than pulling, leaving 3 to 4 inches of stem attached. Plan to harvest before the first hard frost, as the vines will die back. Fruit typically reaches maturity 100 to 109 days after planting.
