Hosta 'Twilight' problems — and how to fix them

Large, lush leaves with golden margins are highly attractive to slugs. Maintain consistent slug controls throughout spring and summer.

The golden-yellow margins are susceptible to sun and wind scorch. Site in a sheltered position with protection from afternoon sun in summer.

Waterlogged crowns are a risk in heavy or poorly draining soils. Incorporate grit or coarse compost to improve drainage at planting.

Large, accessible foliage is a deer favourite. Protect with physical barriers or apply deer-repellent sprays regularly.

Grubs feed on roots below soil level. Apply nematode-based biocontrol in late summer; adults can be hand-picked from foliage at night in spring.
