Troubleshooting
Hosta 'Royal Standard' problems — and how to fix them
Hosta 'Royal Standard' (Hosta 'Royal Standard') 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.
Slug and snail damage
Even in sunnier positions, slugs are a primary threat. Apply controls from early spring and maintain vigilance throughout the season.
Drought stress in sun
Greater sun tolerance comes with greater water demand. Wilting at midday and brown leaf tips indicate water stress — deep soak and mulch.
Crown rot
Despite its vigour, waterlogged crowns will rot. Ensure good drainage especially in heavier soils.
Leaf spot
Fungal leaf spots can occur in wet seasons; remove affected leaves and water at soil level to reduce incidence.
Vine weevil
Large clumps are attractive to vine weevil. Apply nematode controls in late summer to protect the root system.
