When to plant Japanese Anemone?

Japanese anemones thrive in partial shade or full sun, though in hotter spots a position with afternoon shade helps prevent scorching. They prefer loam or clay soil that holds moisture without becoming waterlogged. Before planting, work in plenty of organic matter—compost or well-rotted manure—to improve structure and moisture retention, especially if your soil is heavy clay that tends to bake hard in summer. Plant bare-root or potted specimens in March, April or May for spring planting, or in September and October for autumn planting. Autumn planting often works well because the soil is still warm and plants establish before winter. Dig a hole roughly twice the width of the root ball and deep enough so the crown sits at the same level it was growing in the pot. Space plants 45 cm apart; Japanese anemones spread steadily by rhizomes and will fill gaps over two or three seasons, so resist the temptation to plant too densely. After planting, water thoroughly to settle the soil around the roots and eliminate air pockets. Apply a 5 cm layer of mulch—leaf mould, garden compost or chipped bark—around the base, keeping it clear of the crown to prevent rot. Water regularly through the first growing season, especially during dry spells, to help the roots establish. In exposed gardens, young plants may benefit from a loose cane and tie until the root system anchors them properly. Japanese anemones can be slow to settle in their first year but are long-lived once established, so patience pays off.
