I think one of the peach trees I planted about 2 years ago may be dying. Things are starting to bud out here in Louisiana. This one peach tree has a few blossoms from small branches just above the graft line, however there is no sign of life above them, The branch tips seem to be dead and brittle, not flexible like they are on the other 2 or 3 peaches I have planted over the last 2-3 years.

What should I do if the main trunk is dead? Will it grow back from this limited amount of new growth from above the graft line or would I be better off replacing it now?
