Crop Details

Transplant Conditions: Wait until soil reaches 45°F and nights stay above 35°F before moving outdoors. Harden off for 5 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: Soak nasturtium seed 6–12 hours and sow after frost; they establish best with minimal root disturbance and will still bloom well in lean soil.
