Jumper Leek is an F1 hybrid vegetable that brings labor-saving efficiency to the leek patch with its naturally upright growth habit. Reaching harvest in 95 days from transplants, this variety combines the heavy-feeding demands typical of leeks with a bush-type growth pattern that keeps plants compact and manageable. With resistance to Puccinia (rust), Root rot, and White tip, it's bred to handle common leek challenges while delivering the mild, onion-like flavor home gardeners expect from this classic cool-season crop.

Jumper Leek's upright growth and F1 vigor mean you'll spend less time staking or managing sprawling plants, a real advantage in crowded vegetable beds. The 95-day timeline from transplant to harvest puts it squarely in the sweet spot for fall and winter harvests in most zones. Its triple disease resistance package addresses three of the leek grower's most persistent headaches, letting you focus on feeding and watering rather than fungicide schedules.
Leeks end up in soups, braises, gratins, and gentle sautés where their mild, slightly sweet flavor softens beautifully with heat. Unlike onions, they won't dominate a dish; instead they add body and a delicate savory note. The white and light green shanks are the prized edible parts, though the darker green leaves work fine in stock.

Sow seeds in flats 10 to 12 weeks before your last spring frost, placing them 1/4 inch apart and 1/4 inch deep. You can also use plug flats, thinning to one plant per cell once seedlings emerge. Keep soil evenly moist but not waterlogged until transplant time.
When seedlings reach about 8 inches tall and pencil thickness, typically in late spring, transplant into prepared garden beds. Use a dibbler to create holes 6 inches deep, spacing plants 6 inches apart with at least 12 inches between rows. Only 2 to 3 inches of leaf should extend above the soil surface; don't firm the soil after planting. Instead, let irrigation or rain naturally fill in the dibble hole, which prevents damage to the tender transplant.
Jumper Leek reaches harvest readiness 95 days after transplanting outdoors. Leeks are typically ready when the white shank reaches usable thickness (usually pencil-width or thicker) and before hard freezes in cold climates. Gently loosen soil around each plant and pull or dig straight up; the entire plant comes free, roots and all. Fall and early winter harvests often taste sweetest after a light frost, when sugars concentrate slightly in the shanks.
