Compact Caroina Laurel losing leaves
Hi everyone. I have 3 compact Carolina Laurels planted by a fence facing west. They have been there for about 15 years. During the past 2 years, one of them gradually lost its leaves and they never grew back in spring. The bush is about 10 feet high and it looks bare. It is now spring the there are buds at the tips of the bare branches. The one next to it is now semi-bare and the 3rd one has the most leaves but it still does not look full. I took some branches to a local nursery and they told me it could be because of poor drainage. Has anyone had this problem? I live in northern california. This past winter had been one of the coldest with mutiple days of below freezing temperatures. Thanks.
