Crop Details

Transplant Conditions: Wait until soil reaches 65°F and nights stay above 55°F before moving outdoors. Harden off for 10 days first.
Direct sow preferred — this crop has sensitive roots and does not transplant well. If starting indoors, use biodegradable pots and disturb roots as little as possible when moving outdoors.

Expert Note: Plant only after soil is thoroughly warm (and night temps stay above ~55°F); sweet potatoes usually do best when slips are transplanted rather than seed-started.
