Heuchera 'Obsidian'

Spring - late · Outdoors

Apply slow release fertiliser

Apply a slow release fertiliser which is spread around the root area of plants soon after they have come into growth. (Or apply a liquid feed at regular intervals throughout the growing season.)

This is a simple way to provide a nutrient boost as a single annual procedure.

Spring-Autumn · Outdoors

Water to keep the soil moist

For best results, this plant needs soil that is always moist. Water deeply and regularly as soon as soil appears dry. Even for established plants in the ground, a dry week can cause problems with some soils. Check plants in pots more often, especially in hot weather. Or install an automatic irrigation system which will do the hard work for you, even when you are away on holiday.

Without regular watering some plants never fully regain their beauty.

Spring · Planting

Replant every other year

Every other year the woody stem (in fact part of the rhizome) of heuchera can be replanted. When it reaches more than 7cm in length, simply dig the plant out and immediately replant it more deeply.

Summer-Autumn · Planting

Trim dead heuchera flowers

The delicate flowering stems of heuchera can simply be carefully tugged off, they will readily detach when their time comes.

Compost · Planting

Multi-purpose compost

Use a good quality peat-free multi-purpose compost when growing in pots and containers.
