Planting & Sprout Emergence
2-3 weeksSeed potatoes are planted 4 inches deep in loose, prepared soil. Sprouts emerge 2-3 weeks after planting.
Use certified seed potatoes; cut large potatoes into 1.5-2 oz pieces with at least 2 eyes. Keep soil temperature 45-60°F for optimal emergence.
Vegetative Growth & Earthing Up
3-4 weeksStems grow rapidly with multiple leaves. Plants reach 12-18 inches tall. Begin hilling soil around stems to encourage tuber formation.
Hill soil every 2-3 weeks as plants grow. Remove weeds and maintain consistent moisture. Watch for early blight signs.
Flowering
2-3 weeksPurple-red flowers appear on the stem tips. This indicates tubers are forming actively underground.
Continue hilling and maintain steady watering. Flowers can be pinched off if desired. Monitor for pests and diseases.
Tuber Maturation
2-3 weeksUnderground, tubers are swelling and accumulating starch. Purple color intensifies. Foliage begins to yellow and die back.
Reduce watering slightly as plants mature. Stop hilling. Continue pest monitoring. Do not harvest early for better yields.
Harvest Ready
VariableFoliage completely dies back; skin sets firm and cannot be rubbed off easily. Tubers reach full size with deep purple color.
Cut foliage and let potatoes rest in soil 1-2 weeks after foliage dies for skin hardening. Dig carefully to avoid bruising.
