Troubleshooting
Fothergilla gardenii problems — and how to fix them
Fothergilla gardenii (Fothergilla gardenii) 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 chlorosis in alkaline soil
Yellowing leaves with green veins signal iron deficiency from high soil pH. Acidify with elemental sulfur or use ericaceous mulch; correct irrigation water if hard.
Poor fall colour in shade
Plants grown in deep shade flower sparsely and produce muted autumn tones. Move to a sunnier spot for the signature orange-red display.
Drought stress
Leaf scorch and early drop occur in hot, dry spells, especially on young plants. Mulch heavily and water deeply during droughts.
Unwanted suckering
Slowly spreads by root suckers; remove unwanted shoots in late winter to keep the clump tidy.
