Hello.I have large pinon trees in central New Mexico.They ooze large amounts of sap and have been treated systemically and sprayed..They have boeres and will be cut down soon as I have strugled for three years to little or no avail.Local help is limited and expensive.Would prefer to save them.But will take advice on a good replacement evergreen that goes same height.Am at mile high altitude but these trees mustbelong higher yet.Any help would be welcome.THAX Gio
