I have a 2 thuja occidentalis smarged, 11 years planted in my back garden they are about 13 feet tall, and planted quite close to each other, they’er in a sheltered spot near a corner wall, there is euphorbia planted in front of them, they have turned brown in alot of places and when I touch it lumps of it fall off, this brown is spreading to the top. about 30 percent of each tree is affected. Local gardener told me to treat them with epsom salts disolved in 2 gallons of water which I did today.
