Full sun or light shade. Fertile, deeply dug, evenly moist soil. Amend sandy soil with plenty of compost or leaf mold. These fritillarias are heavy feeders that benefit from a mulch of composted manure or leaf mold in the fall or a dusting of bulb fertilizer in early spring.
Spring-flowering bulbs must be planted in the fall. They need cool soil to make roots before the onset of winter. Cool fall weather arrives at different times from north to south and from high elevations to low.
Please note that the temperature of the soil lags behind the air temperature. You can generally plant later than the windows provided in this map. As long as the ground is not frozen, you can still plant.
