How to grow heucheras

Heucheras are related to tiarellas, also known as foamflower, which have a different shaped leaf and 'foam'-like flowers. Many breeders have crossed heucheras with tiarellas to produce hybrids known as 'heucherellas'. Heucherellas have brightly coloured foliage. Like heucheras, they thrive in shade and work well as ground cover plants. Some have a trailing habit and can be grown in hanging baskets.

How to grow heucheras

Most heucheras do best in dappled shade. Plant them in moist but well-drained soil, or in a loam-base compost if growing in pots. In summer, feed fortnightly with a tomato feed and keep out of direct sun. Tidy the leaves in autumn as they can become tatty. Check pot-grown heuchera plant regularly for vine weevil grubs, as they are particularly susceptible to this pest.

Where to grow heucheras

Most heucheras require dappled shade to grow well, although some do best with a little more sun. Always check the label. Avoid deep shade as this is too much for them. Heucheras thrive in well-drained soil. If you have heavy clay, grow your heucheras in pots.

How to plant heucheras

Plant heucheras from May to September, at the same depth they were growing in their pot, firm well around the rootball and water well. In pots, use a loam-based compost. It's a good idea to add a thick layer of gravel around pot-grown heucheras so the compost is completely covered. This not only conserves moisture but also prevents vine weevils from laying their eggs.

Caring for heucheras

Keep your heucheras out of direct sun. Water pot-grown heucheras regularly but make sure the water can drain from the pot. In summer, feed them fortnightly with tomato food. Tidy around the foliage and remove old leaves in autumn. After around five years, heuchera foliage stars to flatten down. Rejuvenate the plant by lifting and dividing it, using the divisions to propagate new plants.

Preparing heucheras for winter

Heucheras have shallow roots, which means they're prone to 'frost heaving', where the plants are pushed out of the soil by developing ice. This results in the rootball sitting proud of the soil surface, where it can dry out and kill the plant. Add a thick layer of mulch around the base of the plant every autumn, to prevent this.

Growing heucheras: pests and problem solving

Vine weevils are the biggest problem for heucheras. The adults cut notches in the leaf edges, and the grubs eat the plant roots. Check your pot-grown heucheras regularly by gently tugging their stems. If they come away easily, empty the pot and remove any grubs you find (leave them as a treat for the birds). Then wash the roots, ensuring all traces of eggs and grubs are gone, and replant them. Add a thick layer of gravel over the compost, as this can help prevent vine weevils from laying eggs.
