Hello! Im trying to identify these trees. I also thought they were some type of fruitless olive trees, but apparently they're not upon googling them. Also they used to be really nice green, lively, but last few years they look dry and not as many leaves. Is this a soil, drain issue or needs to be fertilized? Thanks so much!
Your photos do not enlarge; could you post close up shots of a branch, some leaves both healthy and unwell, and a more distant shot of the area where they are planted?
So far they look rather dry to me, perhaps because they are growing on a slope?
