Troubleshooting
Sierra laurel problems — and how to fix them
Sierra laurel (Leucothoe davisiae) is generally forgiving once you match its basics, 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)
Yellow foliage with green veins indicates iron or manganese deficiency due to soil pH being too high. Test soil pH; amend with sulphur chips or acidic mulch (pine bark) and apply chelated iron or an ericaceous liquid feed.
Leaf scorch
Brown leaf tips or margins result from drought, too much direct sun, or wind exposure. Ensure consistent moisture, choose a sheltered partially shaded site, and apply a thick organic mulch to reduce moisture stress.
Root rot in stagnant water
Despite liking wet soils, completely waterlogged anaerobic conditions cause Phytophthora root rot. Incorporate organic matter to improve soil structure and ensure some slow drainage even in bog plantings.
