Plant anemone bulbs or seedlings in spring when the weather warms for immediate colorful impact. Choose large flower beds for multiple plantings or individual pockets for smaller plantings. Give anemones sites with full to partial or filtered sun, efficient drainage and good air circulation; the plants produce their best blooms with plenty of sunshine.
Mix the soil for plant nutrition and drainage. Turn 3 to 4 inches of organic compost or garden loam into the top 3 to 4 inches of natural soil to raise the soil level, increase nutrition and ensure soil drainage. The plants thrive in moist, crumbly soil with high organic content.
Plant double anemone cultivars to grow double anemone flowers. Look for this classification on each plant's label. Plant bulbs 1 to 2 inches deep at cultivar-specific spacing requirements.
Water anemones with 2 inches of water every week to keep them moist and growing. Mulch the soil with 1 inch of organic mulch to maintain soil moisture, and feed the anemones in mid-season with a bloom booster fertilizer for lusher blooms.
Deadhead the anemones through the season to encourage repeat blooming. Cut flowers when they open for indoor vases, or pull old, wasted flowers from the plants.
