Troubleshooting
Pink Pewter Dead Nettle problems — and how to fix them
Pink Pewter Dead Nettle (Lamium maculatum 'Pink Pewter') 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.
Leaf scorch in full sun
The silver-grey leaves are particularly prone to sun scorch. Relocate or shade the plant if discolouration and brown patches develop. Morning sun is tolerable; afternoon sun is not.
Powdery mildew in dry spells
White powdery coating on leaves appears when roots dry out while air remains humid. Maintain consistent soil moisture and good spacing. Shear back affected growth.
Slugs and snails
Low, dense foliage shelters slugs. Monitor under the mat of leaves, especially after rain, and apply iron phosphate pellets where infestations occur.
