Hello The middle tree has gone to its happy hunting ground. if i cut it down near the ground, we could trip over the stump. if we cut it say 3ft off the ground, would it shoot again? dunno why it died, everything else is doing fine. should we let the 'saplings' grow? we will definetely not bother buying another! its two playmates will have to do! Thanks for your advice.
That does not look like the best place for trees to grow--under wires and in front of the shrubbery. Do you want them there? I think the dead tree is small enough that you could probably remove the small stump easily enough. If the tree is really dead, it will not grow back if you cut it.
If that is a cherry, the trunk that remains may not be the same ornamental cultivar. The growth next to the trunk is from the different rootstock. If that's left to grow, it would have a very different shape, would not be particularly attractive, and would grow to hide the other two trees.
