Caring for Witch Hazel

Witch hazel has a moderate water need and dislikes both drought and waterlogged conditions. Water regularly during dry spells in spring and summer, particularly in the first two years after planting. Established plants are reasonably drought-tolerant but perform best with consistent moisture, especially on free-draining soils. In winter, natural rainfall is usually sufficient. Mulch annually in early spring with a 5 cm layer of leaf mould, composted bark, or ericaceous compost to retain moisture, suppress weeds, and maintain soil acidity. Feed in March and April with a balanced slow-release fertiliser or a specialist ericaceous feed if your soil is borderline alkaline. A light dressing of blood, fish, and bone or pelleted chicken manure works well. Avoid high-nitrogen feeds, which promote soft leafy growth at the expense of flowers. If leaves turn yellow between the veins (interveinal chlorosis), your soil may be too alkaline; apply chelated iron or sulphur chips and top-dress with ericaceous compost. Witch hazel is fully hardy across zones 5a–8b and needs no winter protection. The flowers are remarkably frost-resistant, though prolonged hard frost may temporarily brown the petals—they usually recover when temperatures rise. Pests and diseases are rare. Aphids occasionally cluster on new growth in spring; a strong jet of water or an insecticidal soap will deal with them. Honey fungus can affect stressed plants, causing dieback; there is no cure, so remove and destroy affected plants. Leaf spot may appear in damp summers but is rarely serious—rake up and bin fallen leaves in autumn to reduce spore carryover. Overall, witch hazel is a robust, low-maintenance shrub once established.
