Cunninghamia 'Glauca' problems — and how to fix them
Cunninghamia 'Glauca' (Cunninghamia lanceolata 'Glauca') 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.
Cold and wind scorch
Cold drying winds and hard frosts brown young foliage and shoot tips. Site in a sheltered position and protect young plants through early winters.
Faded blue colour
Shade, drought stress, or heavy feeding dulls the glaucous bloom. Give full sun and steady moisture for the most intense blue.
Drought browning
Prolonged dryness scorches needles and stresses the tree. Water deeply during droughts and mulch the root zone.
Basal suckering
It throws suckers and reshoots when damaged or cut. Remove unwanted suckers to maintain a clean single-stemmed specimen.
