Troubleshooting
Waldbrunn Spruce problems — and how to fix them
Waldbrunn Spruce (Picea abies 'Waldbrunn') 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.
Spruce spider mites
Cause stippling and bronzing of needles in hot, dry weather. Scout by tapping branches over white paper and treat promptly with a hose-down and horticultural oil.
Root rot in wet soil
Poor drainage or overwatering leads to root rot and dieback. Plant in free-draining soil, raise on a berm in clay, and avoid keeping established plants wet.
Reversion shoots
Occasional vigorous, long-needled shoots from the dwarf form should be cut out before they distort the compact mound.
Winter wind burn
Cold drying winds can brown exposed foliage. Site out of harsh winter wind and water thoroughly before the ground freezes.
