want to re-seed my lawn but waiting till leaves are off my bradford pears. Will they be pretty much done falling before weather drops below 45 degrees?
It can be hard to tell, exactly, when trees will lose the very last leaves. I would guess that it should lose most of them at that time, but I wouldn't be inclined to say they will all have fallen. It would have to stay cold for a good period of time to coax the tree to shed its leaves.
I have planted a few Bradford pears that are about 5 feet tall. How often should I water them, and is a watering bag an ideal method?
Being a tree, they will need much less attention than a plant. If this is outside, you should only ever have to water if it remains dry for more than two weeks. Rainfall will be more than enough, as overwatering will cause infection.
If this is in container, and indoors, then you will water only once the top 3 or 4 inches of soil are completely dry.

My neighbor said I have bag worms on my Bradford pear trees. I thought they only got on evergreen bushes. Several years ago we had juniper bushes all around the house, and got them pretty bad, we sprayed etc, but eventually we just pulled them all out. TY for your time!
I saw some bagworms on my viburnum shrub last summer so, yes, they can land anywhere. Here are some control options:

short of digging them up anything I can do to stop their growth?
Vinegar, and boiling water are two, very good, options when dealing with sucker trees reappearing.

new neighbors have clear cut their entire yard; this is a 1 acre lot subdivision built in '98; how is this going to affect the trees in adjoining yards?; the backyards were left wooded, front yards are Bradford and Bermuda; Coweta county, SW of Atlanta
People usually are more worried about trees overhanging into their yard from the neighbor's or posing a hazard. If trees are removed, I can't think of a negative for you, except it may change the lighting you were receiving, i.e., you may get more sun if their trees were casting shade. However, in a 1-acre lot, that shouldn't be too worrisome.
If you have Bradford pear trees, you might want to remove yours, too. They can reseed and displace the native vegetation. Some cultivars are touted as sterile, but cross pollination with any other cultivar can produce seed. South Carolina will become the second state to ban its sale by nurseries.
