Crop Details

Transplant Conditions: Wait until soil reaches 65°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 Cucurbita maxima like Bonbon F1, transplant only after the soil is reliably warm and keep plants well-watered for the first 10–14 days to reduce root shock.
