When to plant Ramps
NC State Extension says ramps are a spring ephemeral best grown in shady, moist, organic-rich soil under deciduous trees; plant the bulbs about 3 inches deep. Seed can take 2 years to germinate, and when harvesting from the wild, leave the bulb and one leaf in the ground for sustainability.
The calendar shows this cited seasonal window as an approximate band. It does not convert the season into frost-adjusted dates.
