My brother-in-law Steve and myself went to a nursery to pick through hundreds of ilex vomitoria “shillings” for an upcoming workshop I’m doing in June.
They get fat trunks and have awesome taper. Like the sumo I am demonstrating on here.
They can get leaf miners, snow scale and aphids (on new growth).
The worst problem is black spot fungus. But that is easily controlled with a fungicide.
