I have two giant - 8ft wide x 11ft tall - conifers in my front garden acting as a hedge. They are obviously green on the outer branches, but further into the trees, it’s just brown (dead? ) branches. Does anyone know if I cut them back and square them off, will the trees grow green again or will they stay brown? ♀️ Thank you in advance!
