Troubleshooting
Empress Wu Hosta problems — and how to fix them
Empress Wu Hosta (Hosta 'Empress Wu') 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 to mature
Empress Wu takes several years to reach its famous size; gardeners often think it has failed. Be patient, feed and water well, and let the clump establish undisturbed.
Slug and snail damage
Young soft leaves are vulnerable before the foliage thickens. Protect emerging shoots in spring with barriers or ferric-phosphate pellets.
Crown rot
Such a large crown rots quickly in heavy, wet soil. Plant in well-prepared, free-draining ground and avoid waterlogging.
Wind tatter
The huge leaves shred in exposed, windy sites. Plant in a sheltered position to keep the foliage intact.
