Care & growing tips
Plant in moist, rich soil with part to full shade. Never let astilbe dry out — leaves will scorch and plants may die. Divide every 3–4 years. Deadheading is optional — spent plumes add winter interest.

Frequently Asked Questions
01 Why are my astilbe leaves brown?
Almost always drought stress. Astilbe needs consistent moisture — water deeply twice a week in summer.
02 Does astilbe come back every year?
Yes — astilbe is a reliable perennial in zones 4–8. Plants emerge later than most perennials in spring. Divide every 3–4 years to maintain vigor and flower production.
03 Can astilbe grow in full sun?
Only in cooler zones (4–5) with consistent moisture — even there it struggles. Astilbe is a shade-to-part-shade plant. In full sun the feathery plumes scorch and leaves crisp by midsummer.
