Crop Details

Transplant Conditions: Wait until soil reaches 70°F and nights stay above 55°F before moving outdoors. Harden off for 12 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 Crimson Sweet flavor, wait to transplant until soil is warm (about 70°F) and keep vines on a consistent watering schedule until the last couple weeks before harvest.
