Caring for Hebe

Hebe pinguifolia has low water needs once established, making it ideal for dry gardens and gravel plantings. Water newly planted shrubs regularly through their first spring and summer, especially during dry spells, to help roots establish. After the first year, watering is rarely necessary except during prolonged drought. Overwatering or poorly drained soil can cause root rot, so err on the side of dryness. Feed once a year in April with a balanced, slow-release fertiliser such as blood, fish and bone or a general-purpose granular feed. Scatter a small handful around the base of the plant and lightly fork it into the soil surface, then water in if the soil is dry. Avoid high-nitrogen feeds, which promote soft, frost-vulnerable growth. Established plants in reasonably fertile soil may not need feeding at all. Mulch in spring with a 3–5 cm layer of gravel, composted bark, or garden compost to suppress weeds and conserve moisture. Keep mulch away from the stems to reduce the risk of fungal problems. Hebe pinguifolia is hardy in zones 7a–9b but can suffer in severe winters, particularly if exposed to cold, drying winds. In colder areas, position plants in a sheltered spot or provide fleece protection during hard frosts. Evergreen foliage may bronze slightly in winter—this is normal and colour returns in spring. Pests are rarely a problem. Occasionally, aphids may cluster on soft new growth in spring; a strong jet of water usually dislodges them. Downy mildew and leaf spot can occur in humid conditions or overcrowded plantings—improve air circulation and remove affected leaves promptly.
