Hosta 'Regal Splendor' problems — and how to fix them
Hosta 'Regal Splendor' (Hosta 'Regal Splendor') 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
Larger leaves offer more surface area for damage. Iron phosphate pellets or biological nematode controls applied in spring are effective.
Scape breakage in wind
The very tall flower scapes are prone to wind damage. Stake in exposed positions or site in a sheltered border backed by shrubs.
Margin scorch
The creamy-yellow margins are susceptible to sun and wind scorch. Ensure consistent shelter from afternoon sun and drying winds.
Crown rot
Upright vase habit means water can pool at the base in wet seasons. Improve drainage at planting and do not mulch directly against the crown.
Deer browsing
Large, accessible leaves are prime targets for deer. Physical barriers or commercial repellent sprays should be used in deer-prone gardens.
