Troubleshooting
Rheingold Arborvitae problems — and how to fix them
Rheingold Arborvitae (Thuja occidentalis 'Rheingold') 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 colour in shade
Insufficient sun turns the amber foliage greenish and dull; site in full sun for best colour.
Interior browning from drought
Dry soil browns inner foliage; keep evenly moist and mulched, especially in the first two years.
Spider mites
Hot, dry spells invite mites that stipple and brown the soft foliage; hose down and treat with horticultural oil if needed.
Snow splaying
Heavy wet snow can flatten the mound; gently remove accumulation to protect the form.
