Sowing Tips
Transplant Conditions
Wait until soil reaches 45°F and nights stay above 28°F before moving outdoors. Harden off for 7 days first.
Expert Note
For longest storage, transplant sturdy seedlings into well-drained soil and stop fertilizing nitrogen about a month before harvest so the bulbs cure and dry down properly.
