Change in lime peel

Question

My lime tree is 5 years old and has always been healthy. For the last 2 years, the peel looks corrugated and harder than in previous years, also in producing less fruits. Is there a reason for this?

Answer 1

Your tree may be getting to much nitrogen and not enough phosphorus.
Here is an excellent article.
