Hello, We have 5 or 6 Western Red Cedars in our backyard which are about 25 feet high. They are showing signs of flagging (branches in the trees turning yellow/brown), which I know is normal. In fact, I've noticed many cedars in the Surrey, BC area showing significant flagging this year. My question is how much flagging is "normal" and if too much flagging is a sign of a problem. One of our trees is significantly yellow all in the middle of the tree and seems to keep getting yellow branches each day (it started about a week ago, the same time the other trees started to show some yellow/brown branches). Sorry, no pic right now -- I'll have to try to get one tomorrow. I'm afraid that the entire tree is going to turn yellow!! Also, is there a way to minimize the flagging? Would increasing the watering at this point in the year be any help, or if the tree is going to lose it's branches due to some other stress, am I already too late to help it? I had an arborist look at it last Monday (he was giving a quote for pruning) and he said it was just normal flagging, but in the week since he's been here, the poor tree has started looking quite bad (to my untrained eye). When the yellow branches come out, it's going to be quite sparse, if it survives at all. Any thoughs? Thanks. I'll try to add a picture tomorrow.
