Troubleshooting
Coast Redwood Bonsai problems — and how to fix them
Coast Redwood Bonsai (Sequoia sempervirens) 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.
Drought and low-humidity browning
Letting the soil dry or growing it in dry air scorches the fine foliage. Keep moisture consistent and raise humidity in hot, arid conditions.
Frost damage
Coastal redwoods tolerate little hard frost. Shelter the tree over winter and protect the roots from freezing.
Excess basal sprouting
It readily throws up shoots from the base and trunk that can clutter the design. Rub off unwanted buds early, or use them deliberately for forests and lower branches.
Root rot in stagnant soil
Though it loves moisture, waterlogged, airless soil rots the roots. Use a draining mix and ensure the pot never sits in standing water.
