Spiraea 'Gold Flame' problems — and how to fix them
Spiraea 'Gold Flame' (Spiraea japonica 'Gold Flame') 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.
Faded foliage colour
Gold and orange tones wash out in shade. Plant in full sun to keep the bright foliage display.
Leggy or untidy habit
Without pruning it grows open and woody. Shear by one-third to one-half in late winter/early spring to keep it dense; deadhead spent flowers for a second flush.
Aphids
New growth can attract aphids in spring. Hose them off or use insecticidal soap; ladybirds usually control light infestations.
Powdery mildew
White coating on leaves in humid, crowded sites. Improve airflow and avoid overhead watering.
