It could very well be the late frosts; my red mulberry is just now leafing out, and there is a lot of die-back, which I have never seen on it before. Have you snipped back a branch or two to see if the tree is still alive? It looks like there is bud swell, but they may be the ones that were frozen.

your tree should be fully established.. and be able to rebud ...

a freeze can do this... or a long cold spring delay it ...

poke off a bud.. is it green.. or black ... black might indicate it has been dead a long time ...

regardless ... give it a few more weeks ... think in tree time ... they move a lot slower than out expectations...

let us know

Thanks very much for the responses.

I will snip a branch or two tomorrow. It is 43 degrees here and been raining all day. I hope warmer weather is soon here to stay awhile.

ken_adrian I am glad you said to give it a few more weeks. it gives me some hope. The tree looks kinda odd standing there naked at the front of my house.

it may still come out. the late cold weather here in NC killed the leaf buds on all of the crepe myrtles but they regrew
