Lehigh is a high-yielding yellow potato bred for long storage, thriving in hardiness zones 3 through 10. This compact plant produces tubers with excellent keeping quality, making it a standout choice for gardeners who want to harvest once and eat well into winter. Plant seed pieces in early to midspring in well-drained soil, and you'll have new potatoes ready in 7 to 8 weeks, with full-sized tubers following several weeks later.

Lehigh's real strength lies in its storage longevity and consistent yields across a wide climate range. The yellow tubers develop thick skins that set well after vine death, storing reliably in cool conditions for months. This variety handles the cool soil of early spring planting with ease, emerging in just 2 to 3 weeks and reaching harvest maturity dependably whether you're gardening in the Upper Midwest or the Deep South.
Lehigh potatoes work well boiled, roasted, or mashed. Their firm texture and long storage life make them excellent for everyday cooking and meal planning through winter months. New potatoes harvested early are tender and buttery; mature tubers store reliably for extended use.
No timeline data available yet for this variety.
Seed pieces can be planted directly outdoors in early to midspring as soon as soil is workable. Lehigh tolerates cool soil and moderate frost, so planting before the last frost date is safe and encouraged. Plants will emerge in 2 to 3 weeks.
Cut tubers into pieces roughly 1.5 to 2 ounces each (1 to 1.25 inches diameter), ensuring at least one 'eye' per piece. Small whole tubers may be planted without cutting. Plant seed pieces 2 to 3 inches deep, 12 inches apart, in rows 30 to 36 inches apart.
New potatoes can be harvested beginning about 7 to 8 weeks after planting by gently digging around plants while they're still growing. For full-sized main crop tubers, wait until foliage has completely died back, then leave tubers in the ground for an additional 2 weeks to allow skins to set and toughen. Dig tubers carefully, brush off soil, and allow skins to dry before storage.
