Troubleshooting
Japanese Umbrella Pine problems — and how to fix them
Japanese Umbrella Pine (Sciadopitys verticillata) 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.
Slow growth and impatience
Notoriously slow, often adding only a few centimetres a year when young. This is normal; give it good conditions and time rather than overfeeding to force growth.
Chlorosis in alkaline soil
Needles yellow on chalky or high-pH ground. Plant in acidic to neutral soil and use ericaceous feed or mulch to correct and prevent yellowing.
Needle scorch
Hot sun, drying wind or drought browns the needles, especially on young plants. Provide shelter, consistent moisture and a mulch to protect the root zone.
Winter desiccation
Cold, drying winter winds can brown foliage even though the tree is cold-hardy. Site it with some wind shelter, particularly while young and establishing.
