Troubleshooting
Magnolia 'Jane' problems — and how to fix them
Magnolia 'Jane' (Magnolia 'Jane') 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.
Late frost on early buds
'Jane' blooms later than most magnolias, which usually dodges frost, but an unseasonable freeze can still brown open flowers. Avoid frost-pocket sites and south walls that force early opening.
Leaf chlorosis on alkaline soil
Yellowing between green veins signals iron lock-out on chalky ground. Mulch with acidic compost or pine needles and use a chelated-iron feed; long term, choose an acidic planting spot.
Magnolia scale
Soft brown scale insects on stems excrete sticky honeydew and sooty mould. Scrub off light infestations or apply horticultural oil during the crawler stage in late summer.
Transplant sulk
Fleshy, shallow roots resent disturbance, so newly moved plants may stall for a season. Plant in spring, water consistently, and avoid digging around the root zone.
