Troubleshooting
Elizabeth Magnolia problems — and how to fix them
Elizabeth Magnolia (Magnolia 'Elizabeth') 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 damage to flowers
Flowers emerge early in spring and are vulnerable to late frosts, which brown the petals quickly. Plant in a sheltered spot away from frost pockets, or near a south or west-facing wall in cool climates. The tree itself is unharmed.
Coral spot (Nectria cinnabarina)
Pink pustules on dead or dying branches. Prune out affected wood to healthy tissue and disinfect tools. Avoid unnecessary wounding; feed well to maintain vigour.
Honey fungus (Armillaria spp.)
Can affect magnolias on poorly drained or previously wooded sites. No cure — remove and destroy infected root material. Choose a well-drained site and do not plant where honey fungus has previously occurred.
