Troubleshooting
Heucherella Brass Lantern problems — and how to fix them
Heucherella Brass Lantern (Heucherella 'Brass Lantern') 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
Brown, crispy leaf margins from too much direct afternoon sun or drought; move to part shade and keep soil evenly moist.
Crown rot
Mushy, collapsing crown in heavy, waterlogged soil; plant in free-draining ground with the crown at surface level and avoid winter wet feet.
Frost heave
Shallow-rooted crowns can be lifted out of the ground by repeated winter freeze-thaw; mulch and re-firm or replant heaved crowns each spring.
Faded foliage colour
Excessive shade or high-nitrogen feeding turns the amber-red tones green; give brighter light and use balanced, low-nitrogen fertiliser.
