Frequently Asked Questions
Q1 How long do daylily blooms last?
Each individual bloom lasts exactly one day — that's where the name comes from. But each stalk carries 10–20 buds, so a single plant blooms for 3–5 weeks. Reblooming varieties like "Stella de Oro" and "Happy Returns" flower on and off all summer.
Q2 When should I divide daylilies?
Every 4–5 years when flowering starts to decline. Divide in early spring or late summer after blooming. Dig the clump, cut into fist-sized sections with at least 3 fans each, and replant at the original depth.
Q3 Are daylilies deer resistant?
No — deer love daylilies and will eat the flower buds and young leaves. The 'deer-resistant' label is misleading. If you have deer pressure, use repellent sprays weekly or fence the beds during bloom season.
