A few signs a tree may be dead is if the leaves are dead and there are no signs of new blooms. You can also perform a scratch test on some of the branches to check the condition of the cambium layer beneath the bark.

If it is green, it is still alive, but if several are dry, brittle, and brown, the tree may be dying or dead. Always consult an arborist before assuming your tree is dead because you may be able to save it.

The safest way to cut down a tree is to make sure you’re completely prepared and have done all the necessary safety checks, including double-checking your equipment is in good working order, you have plenty of clearance to fell the tree, you’re wearing all the safety gear, and you have a partner to help you (who should also be wearing safety gear). 

You should prune ornamental trees once every other year after the fruit has matured and begun to drop. You should also prune out dead branches whenever you see them. Pruning too often can stimulate more growth, especially in faster growing varieties like Bradford pears.

Costs depend on tree height, trunk diameter, removal complexity, and required equipment.
