Crop Details

Transplant Conditions: Wait until soil reaches 70°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: Start with a warm, well-drained bed and transplant only after nights are reliably warm; bottle gourds hate cold soil and root disturbance.
