Now that we're all seriously considering how to deal with recurring drought in the Lower Mainland (and installing air conditioning), I may have to rejig my back garden where I have emerald cedars providing a screen against a tall house behind me that's close to the fence. They're showing the stress of several summers of drought. I'm on the Sunshine Coast which is now on level 4 water restriction meaning no potable water to be used on the garden and this seems to be the future. Rain barrels don't last long when you've got quite a few cedars, rhodos etc. and several months of little to no rain, never mind the extreme heat we've recently endured. So, if the cedars do die in the next few years, what could replace them that would tolerate drought, grow quickly to at least 15-20', but not much more than that. I've lost my vanderwolf pine to white pine blister rust, so now leery of pines. The garden where I need screen trees is in a north east orientation which normally has lots of shade and moss in the winter months. Tricky. Any ideas?
