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.
