Crop Details

Transplant Conditions: Wait until soil reaches 50°F and nights stay above 40°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: For the best creamy blooms and fewer weak stems, sow after the soil warms and avoid excess nitrogen—nasturtiums prefer leaner soil.
