When to plant astilbe
Astilbe is a rhizomatous shade perennial set out as a plant or division. NC State says it is best divided about every four years, preferably in spring or fall; plant in spring or fall when the soil is workable so the clump establishes before heat or cold.
Astilbe is timed by season rather than your frost dates, so the planting calendar does not generate ZIP-specific dates for it. Check the cited sources below to fine-tune for your area.
