Our Experience
Experience at Great Hill
We feature Crataegus viridis ‘Winter King’ in a grouping around our fountain garden. They provide a beautiful back drop for this garden with aesthetic attributes for each season. We do keep our hawthorns on a fungicidal spray regimen to keep disease in check. We’ve also had to treat for leaf miner.
