Position
Heucheras thrive in shaded or partially shaded spots, making them an excellent choice for woodland gardens, underplanting, or border areas where the sun's rays are filtered. They also do well in container plantings, where their unique foliage can shine. While they appreciate dappled sunlight, they can tolerate some direct sun, especially in cooler climates. However, too intense sun can scorch their leaves, so a sheltered, partly shaded area is ideal.
Prepare Soil
Garden: Plant Heucheras in well-drained, slightly acidic to neutral soil. The soil should be rich in organic matter, which provides the necessary nutrients and keeps the roots cool. Heucheras do not like heavy, waterlogged soil, so if your soil is clay-based, mix in sand or perlite for better drainage. Compost can also be added to improve soil structure and fertility.
Pots: Heucheras are great in pots, where you can easily control the soil and drainage. Use a light, well-draining potting mix like Oderings Potting & Basket Mix, enriched with organic matter. Ensure the pot has adequate drainage holes to avoid waterlogging.
Feed
Garden: Heucheras are not heavy feeders, but they will benefit from a slow-release fertiliser in spring, especially if the soil lacks nutrients. Apply a balanced general fertiliser and use compost around the base of the plant to improve soil quality over time. Heucheras typically do well with light feeding in spring and again after flowering.
Pots: Heucheras planted in pots need more regular feeding than those planted in the ground. Use a slow-release like Total Replenish twice a year or liquid fertiliser every month during the growing season. Be careful not to over-fertilise, as too much can lead to leggy growth and less vibrant foliage.
Watering & Mulching
Once established, heucheras are fairly drought-tolerant, but they will perform best with consistent moisture. Keep the soil moist but not soggy, especially during hot spells. Water at the base of the plant to avoid wetting the foliage, which can lead to disease.
A light layer of organic mulch around the base of the plant will help retain moisture, suppress weeds, and keep the roots cool. Use materials like bark or shredded leaves to mulch Heucheras, but avoid piling it too high around the crown.
Protection
While Heucheras are hardy, they can still benefit from winter protection in colder climates. In frost-prone areas, you may need to cover the plants with frost cloth or straw during extreme cold spells to protect the delicate leaves. Heucheras are pest-resistant but watch for aphids or snails, which may occasionally target the soft leaves.
Pruning
The flowers of heuchera can be cut for floral arrangements. Their delicate, airy blooms make a lovely addition to indoor bouquets, adding a whimsical touch to any display. As for the foliage, you can cut back any dead leaves in early spring to make room for new growth.
Garden Expert Tip
Heucheras are perfect for adding year-round colour and texture to your garden. Their vibrant foliage can transform a dull corner into a striking feature, even when not in bloom. Be sure to place them in spots where their leaves can truly shine—whether in the shade of tall plants or as an underlayer for taller shrubs and trees.
If you’re looking for a plant that brings contrast, beauty, and season-long appeal, Heucheras are a must-have for your garden. Keep them healthy with regular watering, well-drained soil, and occasional feeding, and enjoy the show.
