My neighbor just hacked away at a wild non-fruiting mulberry tree adjacent to my property. She insisted the green bumps were insect eggs. I don't think they are since not all leaves have them and the leaves were mot chewed by anything. Actually is was a really healthy looking tree. She destroyed half of the tree. What are the green bumps that look like small peas on the underside of the leaves. What can I do to undo some of the damage she caused. That is after I clean up the mess of leaves and branches.
She is right. They are insect eggs, and even mature specimens on occasion.
Galls are, usually, harmless in most cases, though.
Mulberry trees will really enjoy a thorough pruning, so she did no harm in doing so.

Last year it had what was called popcorn disease. This is a huge tree and this year it put out the fruit but it is dried up and never turned color.
The popcorn disease fungus carries over from year to year. It interferes with the ripening of the fruit and it stays greenish. Collect all the infected fruit and dispose of in trash. See below:
I know nothing about Mulberry Trees other than picking their fruit. Though I would like to know a way to harvest the berries more efficiently as well.
They benefit from annual pruning to get rid of dead branches and to remove older, less productive branches.
You can take a tip cutting at any time, and root them inside.

I dont know whether it needs water or no water
It's likely suffering from transplant shock. Water the root zone frequently. Keep the soil moist but not saturated till it recovers.

The question didn't seem to have finished, but I think I know what is being asked.
Watering should be done when necessary, and not on schedule. This will need to be watered once the soil dries down to about 5 inches or so, very thoroughly. You can get away with watering a little more often, but they will tolerate drier conditions at the top of the soil level.
Overwatering can cause soil infections, which can cause leaf drop.
I would treat with a fungicide, and make sure to use proper care with the tree. These articles will help:

Runs down the trunks leaving a black trail. Seems to be severing the affected branch from the main trunk.
This condition is not necessarily fatal to your tree, but indicates that there's been an injury, or a branch has grown out in an odd way, creating a naturally occurring "injury." The only remedy I've found in my research is spraying the area with a diluted mixture of bleach and water to kill the bacteria that gravitates toward the "wound."

Our tree is a weeping mulberry. We believe it to be male, it doesn't bear fruit. Thanks for any advice.
You can propagate your tree from cuttings. Here's an article to show you how:
