Dwarf Mountain Laurel Elf problems — and how to fix them
Dwarf Mountain Laurel Elf (Kalmia latifolia f. myrtifolia 'Elf') is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Chlorosis (yellowing leaves)
Caused by alkaline soil or hard tap water raising soil pH above 6, locking out iron and manganese. Apply sequestered iron chelate and acidify with sulphur chips; always use rainwater or acidified water.
Vine weevil (Otiorhynchus sulcatus)
Larvae feed on roots causing sudden collapse; adults notch leaf margins. Apply biological nematode control (Steinernema kraussei) in late summer or early autumn when soil is warm and moist.
