Troubleshooting
Japanese Cedar 'Globosa Nana' problems — and how to fix them
Japanese Cedar 'Globosa Nana' (Cryptomeria japonica 'Globosa Nana') 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.
Foliage scorch in containers
Potted plants dry out fast and brown at the edges. Use a large container, moisture-retentive compost, and water regularly in heat.
Winter bronzing
Cold turns the dome bronze-purple; this is normal seasonal colour, not disease, and greens up again in spring.
Snow splitting the dome
Heavy snow can splay the rounded form. Brush snow off gently and tie in if needed to preserve the shape.
Inner browning from congestion
Dense interior growth can die back from shading. Light thinning improves airflow and keeps the centre healthy.
