When to Plant Astilbe Roots?

Planting: Plant astilbe in spring or fall. Avoid summer planting due to astilbe's aversion to drying out. Astilbe can be started from seed, but it may be hard to germinate and will take a few years to get a substantial plant. Since astilbe spreads easily, a better way to get new transplants is to divide mature plants.

When can I plant bare root astilbe?

Astilbes come as either bare root crowns or in containers. Plant the crowns in the early spring. Potted plants can be planted any time up through mid-August.

How long does it take for bare root astilbe to grow?

Expect root growth to begin almost immediately after planting. In warm climates, top sprouts will form within a few weeks; in cool climates sprouts will emerge in the spring. Plant your roots in the fall 8 weeks before hard frosts typically occur in areas with winter temperatures that drop below freezing.
