I live in central Arkansas and I've been having trouble with conifers in general. I have had Japanese black pine, white pine, red pine, Boznian pine, hinoki cypress, oculus draconus, shimpaku junipur, etc. All do well for a number of years, I've actually had a couple for up to 5 years. But, then the needles begin to brown from the branch outward towards the tip and within a week or less the plant is dead. I've lost several really nice trees, but insist on continuing to try. I've taken trees when ailing to a local nurseryman who said that since the needles are browning in this manner that it is indeed a fungus. He did not identify the fungus by name, but recommended I treat with "Rescue" weekly. Well, as already noted the trees are usually dead within a week. I tried Rescue and the trees lived longer, by a couple of days, but ultimately still died. My trees sit under some large hackberry trees that have some kind of leaf bacteria/larva, which I have sent to the county offices for accessment. They reported that there shouldn't be a problem. All my deciduous trees are doing well and sit under these same trees with no signs the problems from the larger trees. It is only my conifers that see to be cursed. Currently, I have 3 white pines that I've had for 5 years that are doing well and some small junipur that I inherited that is also doing well. I would like to have some additional pines and junipur, but fear investing money, time and energy only to watch them perish as before. I'm open to any suggestions.
