Mountain Laurel in June: monthly care

Mountain laurel has moderate water needs and dislikes both drought and waterlogging. Water regularly during the first two growing seasons to establish a deep root system, particularly in dry spells. Once established, water during prolonged dry periods in spring and summer, especially if planted in free-draining soil. The shallow root system dries out faster than deep-rooted shrubs, so check soil moisture 5 cm down and water thoroughly when dry. Reduce watering in autumn and winter unless conditions are exceptionally dry. Feed in March and April with a slow-release ericaceous fertiliser formulated for acid-loving plants, scattering it evenly around the root zone and watering in well. Avoid general-purpose or high-nitrogen feeds, which can damage the roots and reduce flowering. A second light feed in early June supports flowering, but don't feed after mid-summer—soft new growth won't harden off before winter. Refresh the acidic mulch layer each spring, topping it up to 5–8 cm. This is especially important if your soil is naturally neutral, as mulch breakdown helps maintain acidity. Mountain laurel is fully hardy in zones 4a–9b and needs no winter protection in temperate Europe, though evergreen foliage may bronze slightly in cold winters—this is normal and greens up in spring. Common problems include vine weevil, whose larvae eat roots; check for notched leaf edges and treat with biological controls in late summer. Leaf spot fungi can occur in wet, humid conditions—improve air circulation and remove affected leaves. Chlorosis (yellowing leaves) indicates alkaline soil; apply chelated iron and mulch with ericaceous compost to restore acidity. Mountain laurel is generally low-maintenance once its soil and moisture needs are met.
