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 Hearts of Gold, wait for consistently warm soil before transplanting (cold soil quickly stalls cucurbit growth), and protect plants for the first 1–2 weeks with row cover if nights are cool.
