Growing Coral bells in a pot

Heuchera micrantha has moderate water needs and prefers consistent moisture without waterlogging. Water regularly during the first growing season to help roots establish, particularly in dry spells. Once established, it tolerates short dry periods but performs best when the soil doesn't dry out completely in summer. In shaded positions, natural rainfall is often sufficient except during prolonged drought. Reduce watering in autumn and winter when growth slows, and avoid overhead watering which can mark the evergreen foliage. Feed in March or April as new growth emerges, using a balanced general-purpose fertiliser such as blood, fish and bone or a slow-release granular feed scattered around the base at the manufacturer's recommended rate. A second, lighter feed in April can boost foliage quality, but avoid overfeeding—too much nitrogen produces lush leaves prone to disease and reduces the intensity of any purple or bronze tones in the foliage. Top up mulch annually in spring to suppress weeds and retain moisture. Heuchera micrantha is evergreen and fully hardy, requiring no special winter protection in temperate Europe. The foliage may look tired by late winter, but the plant will refresh itself in spring. Vine weevil is the most common pest; adult beetles notch leaf edges while the larvae feed on roots and can kill plants. Check for signs in late summer and consider using biological controls (nematodes) if you spot damage. Powdery mildew can occasionally affect foliage in dry conditions with poor air circulation—remove affected leaves and improve spacing. Rust and leaf spot are rare but more likely in overcrowded or poorly drained sites.
