Troubleshooting
Spiraea 'Goldflame' problems — and how to fix them
Spiraea 'Goldflame' (Spiraea japonica 'Goldflame') 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.
Foliage losing gold colour
Excess shade or high nitrogen fertiliser causes the golden tones to revert to green. Ensure full sun and avoid high-N feeds.
Leaf scorch on gold foliage
Golden leaves are more susceptible to scorch in intense sun combined with drought stress. Water consistently and apply mulch to buffer soil moisture.
Powdery mildew
Can affect plants in congested, shaded, or drought-stressed conditions. Improve airflow and maintain consistent soil moisture.
Aphids
Soft bronze spring growth is especially attractive to aphids. Treat at the first sign with insecticidal soap.
Reversion to green shoots
Rarely, vigorous green-leaved shoots appear; prune these back to their origin immediately to prevent them dominating.
