English Laurel Hedge Decline in Wet Clay: Root Rot and Replacement Species

English laurels dying limb-by-limb in heavy, wet clay after 10 years: poor drainage finally exhausted stored root starches. Laurels tolerate moisture temporarily but succumb to Phytophthora root rot in chronic wetness. Raising soil level only delays the inevitable—clay underneath still holds water.

Replace with wet-tolerant screening shrubs: Viburnum (V. dentatum, V. nudum), Clethra (summersweet), Kalmia (mountain laurel), Cornus stolonifera (red-twig dogwood), Andromeda polifolia (bog rosemary). All provide year-round presence, tolerate wet clay, and offer seasonal interest.

Plant on berms or raised beds. Space for air circulation. Mulch. These alternatives thrive where laurels failed.
