Cracker Jack is an organic F1 hybrid watermelon that delivers reliable flavor and performance in just 87 days from transplant. This bush-type variety thrives in northern gardens where it benefits from plastic mulch and row covers to build heat and momentum early in the season. The compact growth habit and consistent yields earned it the reputation as a workhorse in organic production, proving that you don't need a sprawling vine to grow outstanding watermelons.

Bred for organic growers who refuse to compromise on taste, Cracker Jack combines the efficiency of an F1 hybrid with the flavor integrity that makes gardeners reach for watermelon in the first place. Its bush growth habit saves space without sacrificing yield, and the 87-day timeline from transplant means northern gardeners can actually finish a crop before frost. The variety responds beautifully to row covers and plastic mulch, techniques that reward attentive growers with earlier harvests and sweeter fruit.
Cracker Jack watermelons are grown for fresh eating and table enjoyment. The variety's reputation for great flavor makes it a choice for anyone seeking a ripe, sweet melon to slice and serve fresh during summer months.

Sow seeds indoors in 50-cell plug trays or 2, 3 inch peat pots in late April, roughly one month before your transplant date outdoors. Plant 2 seeds per cell or pot at a depth of ½, 1 inch. Maintain soil temperature at 80, 90°F (27, 32°C) until germination occurs. Once sprouted, grow seedlings at 75°F (24°C). About a week before transplanting, reduce both water and temperature to harden off the plants and prepare them for outdoor conditions.
Transplant into the garden after frost danger has completely passed, when weather is warm and settled. Space plants 2, 3 feet apart in rows positioned 6, 8 feet apart. Handle young plants carefully to avoid shock; they are fragile at this stage.
Harvest Cracker Jack watermelons at 87 days from transplant when fruit reaches mature size and the field spot (where the melon sat on soil) changes from white or pale to cream or yellow. Look for a dull, waxy finish on the skin rather than a glossy shine, and the melon should feel heavy for its size, indicating good water content and ripeness.
