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: Because zucchini is a cucurbit, transplant only when soil is reliably warm and handle roots gently to avoid shock—otherwise direct sow is usually even better.
