Frequently asked questions
When do peonies bloom in the Bay Area?
Most peonies bloom in spring, typically from late March through May in many Bay Area microclimates, depending on variety and winter chill.
Do peonies need full sun?
Yes—aim for 6+ hours of sun. In warmer inland areas, light afternoon shade can help blooms last longer.
How often should I water peonies?
Water deeply after planting and during dry spells. Once established, deep watering every 7–14 days is often enough, adjusting for heat and soil type.
Are peonies deer resistant?
They’re often considered deer resistant, but no plant is fully deer-proof—new growth may still be sampled.
Why aren’t my peonies blooming?
Common causes include planting too deep, not enough winter chill, too much shade, or excessive nitrogen fertilizer. Also note: new plants may take 1–3 seasons to flower well.
Can peonies grow in containers?
Yes, but choose a large pot with excellent drainage and plan for consistent watering. Herbaceous peonies generally do better in the ground long-term.
