Grower Tips

Planting: Plant bulbs in fall, 5 to 6 inches deep and 5 to 6 inches apart. Handle carefully—Fritillaria bulbs are large, irregular, and prone to drying out, so plant promptly after purchase. Position bulbs on their side to prevent water from collecting in the central depression, which can cause rot.
Location: Full sun to light shade is best. Fritillaria meleagris prefers dappled light, while F. imperialis (Crown Imperial) thrives in sunnier spots.
Soil: Well-drained, humus-rich soil with a slightly acidic to neutral pH (6.0–7.0). Add grit or sand to improve drainage, especially for Crown Imperials.
Watering: Water after planting and during dry spells in spring. Once foliage dies back, reduce watering—bulbs prefer dry summer dormancy.
Temperature: Hardy in USDA zones 4–8. Bulbs require 10–14 weeks of cold to bloom properly.
Fertilization: Apply compost or a balanced fertilizer in early spring as shoots emerge. Avoid overfeeding.
Pruning: Remove spent flower stalks after blooming. Allow foliage to die back naturally to feed the bulb.
Propagation: Divide clumps every few years in summer when dormant. Replant offsets promptly.
Pest & Disease: Generally pest-resistant. Crown Imperials emit a musky scent that deters rodents and deer. Ensure good drainage to prevent rot.
