Can somebody help me? I have a tree with red bark,red leaves,and black red berries. Are the berries edible? What is this tree?
Welcome to the forum. Without a photo it's not likely to get an ID and irresponsible to suggest something is edible.
Red leaves and black-red fruits in Colorado might be a purple-leaved chokecherry. As indicated, don't attempt to consume without being certain of identification.
