Q. Flowering plum tree

I have a 13 year old flowering plum tree and we have noticed that some of the leaves and branches are dying, so I cut them off and more come. Please help, I don’t want to lose this tree.

It could have a fungus or pests could be to blame. You can remove any dead growth and it should regrow. Look for pests and treat the tree with Neem oil (both an insecticide and fungicide) and see if this helps at all.

Q. Trees

We have a fruitless Plum tree which flowers in spring and was doing good up until a couple of yrs ago. Colorado experienced an early cold winter. The spring after the tree only grew leaves on about a quarter of the tree the rest of the tree was bare. This spring the tree has only grown flowers on a couple of the branches. Could u help diagnose the issue?
2- yes ago W also planted three Emerald Green Arborvitae Smaragd. Two died and one was dead except on one side. We thought we just purchased bad trees and returned them and got two more trees, and replanted them. Needless to say all three are now dead. Now we r wondering if maybe the Plum tree has something that has spread to the other trees

Thank you in advance.

Your Plum Tree sounds as if it suffered winter damage and if a tree is stressed it is more likely to suffer from pests or disease.
Trees do die from particularly harsh winters and there is really not anything that can be done.
If the branches break and snap they are dead. If you can scratch the bark and still see green, they are still alive.

Harsh winter weather can easily damage Arborvitae and especially new plantings.

Here are some articles that will help you.

Q. Fungi

My ornamental plum tree has a fungus growing on the main trunk and other branches; can I shave it off?

The part of the fungus you see is the fruiting body (mushroom-like spore dispersal organ), the growing body is the mycelium which is deep inside the woody tissues. It doesn't do much good to shave off the fruiting body, it would be mostly for cosmetic reasons.
From the photos this tree appears to be in bad shape, poorly pruned, sunburned and with extensive decay. The fungus present appears to be growing out of dead wood and cavities, and not affecting the living tissue. But its hard to see what's going on without photos of the entire tree.
