lemon trees nipped by frost.

Question

What should you do if the tree is returning some green leaves at the base, but it is dead looking on top? should the brown limbs be trimmed?

Answer 1

Not until warm weather returns. You should cut off the bottom growth, though. These are likely below a graft point, and not the same tree. These will quickly outgrow the main tree.

Just trim the dead growth after you see signs of new growth on the top portion of the plant.
