42+ Murray Cypress Turning Brown. Persistently wet foliage from heavy rainfalls and overhead irrigation. Entire lower canopies may turn brown, leaving only a small section of green needles at treetops.
These three fungi enter into the tree during the summer months when the heat enlarges the tree's stomata (pores on the leaf) and allow entrance of the fungi.
They also can tolerate wet sites a bit better as well as being more resistant to fungus disease. There's healthy growth on the top though but i'm worried the shedding will catch up. Murray cypress' primary function is for privacy purposes. Fast growing, with evergreen, feathery foliage and a pleasing, slender profile, it makes an excellent specimen tree or screening plant.
