Good day. I live in Kelowna and have a couple questions regarding my ceders. The hedge gets regular water, always has. It's about 20 years old. It was always trimmed yearly until about 4 years ago but has been neglected since then due to illness in the family. My questions are why are there so many seeds on the branches. Also the hedge is nice and green on the outside but about 6 to 8 inches in it is all brown. Can I trim 3 to 4 inches off without hurting them? And will the inside green up a bit when it is trimmed. I have attached a few photos. Thanks for any info you can give me.
