And this is the experience for most people who get to work with this material...Dieback is common and it some instances Thuja are more finicky than Hinoki in regards to shoot selection and the results thereof......I agree that you probably will lose some foliar extensions due to aggressive reduction...You have to try and work these guys back, almost like you would with an Hinoki
Do people grow thuja in New Orleans? Curious as to their southern range...
