We will replace any tree that has died due to natural causes within our two year warranty. Generally, it is easiest to tell if a tree is dead in the summer months because it will not have any leaves. Your tree may be removed at any time of year but we will wait to replace it until the spring and fall, which are the best seasons for planting.  If you notice a dead tree, or have questions about the health of a tree planted by the Baltimore Trust, you can let us know by reaching out to us at info@baltimoretreetrust.org.
