Hedges in trouble
Hi, I live near Los Angeles area and my question is about Privet hedges that I have grown for past 20 years near my house. Since last year, some plants stopped branching off. Stems got naked and eventually whole plant died and i ended up replacing several of them. I dug up around the roots and no abnormal signs that I could see. Attached pictures show this condition happening on another side opposite to where I lost several plants. Anything I can do to save them please? Thank you in advance!
