We just bought the house and unsure of the history of these trees. There are five established trees planted close together. One guy said they were pine and another said they were juniper. I have no idea. They drop nuts. The one on the far left appears to be dead. There is new growth at the bottom but everything else is brown and appears dead. I took several close-ups. There appears to be fungus on them. The prior owner had pine straw about 6" thick. I don't think I can salvage the one on the end, but the others may have a fighting chance. Do you have any suggestions? Thank you in advance for any advice!
