Growing Instructions
Plant Astilbe outdoors in spring after all danger of frost has passed in a partially shaded to full shade location. The ideal soil is rich and porous and drains well, yet still holds enough water for the roots. If your soil is heavy clay and drains slowly, or very sandy and does not hold water, add organic soil amendments like peat moss or ground bark. Spread a 3-4 inch layer of soil amendment if needed and incorporate into the soil to a depth of 10 inches. Plant roots 1-2" deep and 15-18" apart. Cover with soil. Water thoroughly at planting. While actively growing, water frequently and thoroughly so that water will reach roots. Mulch to keep the soil cool and to prevent the soil from drying out. Fertilize regularly. Remove foliage after it has completely yellowed and died back. Divide every two to three years.
Care Tip
Does not tolerate hot summer temperatures and is a good choice for moderate climates. Likes moist conditions.
