Is there any way to make sure or prevent this from happening to my remaining three pines or do I replace and go with something else. Besides that what does it cost to replace a tree these days and what factors are there to take into consideration? I have some pictures here to help. I have been told they are dead and need replaced. I have been told that it is Cronartium ribicola, white pine blister rust? Are these white pines? I live in Northern Alabama and I am losing a pine a year. I have four left I would like to save or replace.
