We have Cedar Trees that are about 30 years old and 25-30 feet high. If we lop them to stop them growing any higher might that damage the trees? Any advice will be appreciated.


Thank you for your inquiry. Regular trimming of your cedar hedge is extremely important in order to grow a dense and healthy looking hedge. Removing dead, diseased, or damaged branches should be done anytime a problem pops up and can be safely corrected. Removing branches that cross and could potentially rub against each other is important because these injuries can be an entry point for disease. When you are trimming a cedar it is important to know that cedars will not generate new growth from bare old wood.The best time of year to cut your cedar hedge is in early spring before the new growth appears.
