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: For best carving quality and fewer vine stress issues, prioritize direct sow or transplant only when soil is reliably warm and nights stay mild, then keep plants evenly watered to avoid rind cracking.
