Howdie,
It's my first season with a lemon tree. I'm pretty sure it got frost damage over the winter.

We are currently keeping plenty of tree and shrub mulch down around the base. Our plan is come May 1st, we are going to cut it back to the green. Right now the outer branches look dead, there is no growth. However there are signs of life. The larger branches at the base of the tree are nice and green, and we are seeing some sprouts. Is there anything other than trimming off the dead branches and keeping it mulched that we can do to save our little lemon tree?
How often should we be watering? Any clue what sort of lemon it is? We think it's Meyer, but we are not sure.

Thanks in advance.
I am adding several photos.
