Why Grow Montana Jack?

• Early ripening — often orange by mid-August from a June transplanting; the solution for short-season gardens that can’t reliably ripen standard pumpkins
• Plant in June or July — later planting window than most pumpkins; ideal for northern climates and high-altitude gardens
• Prolific — average of four fruits per plant; some fruits reaching 20 lbs
• Dual-purpose — excellent for carving and for pies; delicious sweet flavor
• Bred by John Navazio — one of the most respected plant breeders in the heirloom seed world
• Rare and hard-to-find — not widely available; a genuine specialty variety

Growing Notes

Plant seeds outdoors after frost risk has passed — can be planted as late as June or July in most climates. Plant 3–5 seeds 1 inch deep per mound; thin to 2 strongest seedlings. Water deeply but infrequently. Harvest when skin is fully orange; cut with a 2–3 inch stem attached.
