IN our yard in manitoba, I have a number of dogwoods, all of which have developed a fungal infection, verified by a biologist. i have sparyed with Tilt and Bonomyl, should I replaec them or trim them back and wait. I have a number of cistena cherries as well, they do not seem hardy, having to be cut way back due to dead branches each year. Especially in the west side in the sun they grow poorly. Does any one have experience with the Diablo Ninebark? Dave C Souris Manitoba, Canada
