I bought my house three years ago and I have a lime tree in my garden, but not much fruit. The first year the fruits fell and the leaves and branches had disease. I cut it and added fertilizer and water. This year it produced about 20 to 25 limes. What should I expect if I cut it again, and about the regrowing of fruits? My neighbor said to not cut, it will die. Please help to have a healthy tree and much more fruits.
