Mine went yellow in the first year, many years ago now. My neighbour suggested Miracle gro. They went green after that but have had yellow times since. They are now huge but some are quite yellow.
I have a short length of hedge, about a dozen plant,s that has always been green. They're in poor soil and frequently disappear under weeping willows but they are the happiest.
