The peach tree in my garden gave a lot of fruits last year. Then in winter- around feb - I pruned the tree. After that this summer- I am not getting any leaves in the branches. I am worried if it is dying. I live in Los Angeles- the weather is moderate- between 15 degrees to 22 degrees. Please help me understand how to review my peach tree. Sharing pic of current state of tree for reference. Only 1 branch has leaves.
