Troubleshooting
Worplesdon Sweetgum problems — and how to fix them
Worplesdon Sweetgum (Liquidambar styraciflua 'Worplesdon') 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.
Autumn colour variability
Colour intensity depends on temperature differential between day and night in autumn. Warm autumns or sheltered urban sites can produce less vivid displays. 'Worplesdon' is more consistent than the straight species but variation still occurs seasonally.
Transplant sensitivity
Liquidambars resent root disturbance after establishment. Plant from a container or rootball in early autumn or spring; stake for two years; water attentively for three summers. Moving a mature specimen is rarely successful.
Chlorosis on alkaline soils
Interveinal yellowing appears rapidly when planted in chalky or high-pH soils as iron becomes unavailable. Test soil before planting; acidify if needed and avoid chalky backfill. Incorporate acidic organic matter at planting time.
