Troubleshooting
Hazel Smith Sequoia problems — and how to fix them
Hazel Smith Sequoia (Sequoiadendron giganteum 'Hazel Smith') 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.
Chlorosis in alkaline soils
Yellow needles indicate iron deficiency in high-pH soils. Apply chelated iron and acidify the root zone with sulphur.
Root rot in wet soils
Prolonged waterlogging causes rapid root decline. Ensure excellent drainage before and after planting.
Scale insects
Occasionally affected by scale insects. Treat with horticultural oil in early spring.
Snow damage
Heavy snow loading can break branches on young trees. Knock snow off gently after snowfall.
Drought stress
Extended dry periods cause needle browning and dieback in young trees. Deep, regular irrigation is essential during establishment.
