Lemon Tree is Splitting

[ohanamama]

Thanks All! I love Punaweb!

I dutifully pinched off all the blossoms[V].

I'm pretty sure it's not splitting at a graft but maybe from wind damage?

Questions

If I tape it, does it matter if the split is fresh or not? It seems older, and rather dry especially at the top.

If I cut the weaker branch off, will the tree survive and flourish with only half its main trunk left? Should I tape the missing branch spot to protect it?

I've got alot to learn!
