As an x nurseryperson of over 40 years, I would like to add from personal experience and from customers, a variation of the causes described is sun burn---a situation often not thought of but happens most frequently.  
Sun burn then provides the entry point for the diseases describe. A lost recommendation is painting the trunk with White latex paint, diluted 50 % latex paint and 50% water to prevent sunburn. You know it was sunburn damage because the damage would be on the south or west side of the tree.

Thanks for your input... we respect your well-earned knowledge and our oversight... we fully agree with your comment and recommendation... and it would be especially important if the tree is replaced... and maybe would be even appropriate if the owner decided to leave the tree for another year ... I would add that the latex paint is usually cited as "interior" latex paint to apparently eliminate the possibilities of toxic preservatives.  
I was especially disheartened to see this apricot tree in its present condition. I remember many joyous summer hours as a child sitting in various neighbors' apricot trees eating their ripe apricots. It seemed as if everybody had one in their backyard on the SF Peninsula where I grew up. But as a CC County home gardener I have yet to have success with apricot trees losing several of them to various diseases where you keep cutting off the infected branch to the point where you only have the "stump"... and losing another to a neighbor's eucalyptus tree falling on it... or finding the squirrels eating all of the dozen or so apricots one year ... I'm even more frustrated these days without any apricot trees in my garden' but I have found several this August that are "pickable" from the sidewalk when walking my pup early am... please don't tell them though as I'm already working on dreams of next year.

My apricot tree, 5-7 years old, would not drop its leaves this past winter. In January fruit began to form. In Feb. and Mar. the rains came and knocked off most of the fruit and leaves. Today the tree is barren with remnants of yellow leaves wilted sparsely on the branches. There is one lower branch that has new growth and has developed fruit. Is this the end for my apricot?

We have your message. I'm not optimistic about the apricot's future, but I need to do some research. I remember joyfully as a kid sitting in my neighbor's apricot tree eating away this time of the year. However, as an adult with my own apricot tree you could count all the apricot fruit it produced on two hands... and I had to fight off the squirrels for those... however, the several rental houses I pass in the morning walkig the dog do great and nobody is really maintaining them... well I do by "thinning" out the crop each morning now that they are ripe... Anyway be back with some hopefully good ideas about next steps... not too optimistic though at this point.

My apricot tree broke during a windy day just above the base  
Please tell me if I can grow roots on the bottom of the tree and  
How please help  
Blog Editor: Depends upon whether the break is above and/or below the graft between the root tree and/or the fruit producing graft. Personally this blog editor would suggest getting a new tree to replant... and that you follow the guidance on pruning apricot trees such as
