Hosta 'Wheel of Fortune' problems — and how to fix them

Despite better resistance than smooth-leaved hostas, slug damage still occurs on thicker-textured varieties. Maintain preventive controls from early spring.

Excess nitrogen produces lush, flat new growth that lacks the characteristic puckering. Use balanced rather than high-nitrogen feeds and apply at recommended rates only.

Ensure free drainage at the planting site. The large, heavy crown of mature plants is particularly at risk from waterlogging in winter.

The pale-centred portions are vulnerable to sun and wind scorch. Site in sheltered partial shade and protect from drying winds.

Root-feeding grubs cause wilting. Apply nematode-based biological control to the root zone in late summer.
