When to plant Coral bells?

Heuchera micrantha thrives in partial shade or full shade, making it ideal for woodland gardens, shaded borders, or north-facing beds where many other perennials struggle. It tolerates a range of soil types but performs best in well-drained loam or sandy soil that doesn't become waterlogged in winter. Before planting, dig over the soil to a spade's depth and incorporate a generous amount of organic matter such as garden compost or well-rotted manure to improve both drainage and fertility. Plant in March, April or May for spring planting, or in September and October for autumn establishment. Space plants 35 cm apart to allow for their mature spread of 30–40 cm. Dig a hole slightly larger than the root ball and position the crown at soil level—planting too deeply can lead to rot, while planting too high exposes the roots. Firm the soil gently around the roots to eliminate air pockets. Water thoroughly immediately after planting to settle the soil and help roots establish. Apply a 5 cm layer of mulch around the base, keeping it clear of the crown itself, to retain moisture and suppress weeds. In exposed sites, the evergreen foliage can suffer wind scorch, so choose a sheltered spot if possible. Heuchera micrantha is fully hardy to zone 4, so winter cold is rarely an issue in temperate Europe. New plants establish more reliably in spring when soil temperatures are rising, but autumn planting works well if the ground isn't too wet or heavy.
