Hi friends, sorry to bother you I´m new in this forum. I'm getting trouble with a lemon tree, i bought it 4 months ago, It came hit fruit and all that, so I plant it. I rinse it every 3 days, weather in my location is from 41 to 89 max. I´m using forest soil and I fertilized it with a compound of Nitrogen, Phosphorus and Potassium. The problem I got is as follows:
1. The fruits that it had when I bought it remains the same, no growth, no yellow color, no change at all, only one of them is dead, but the rest remains the same (Image 1, and 2)
2. It flourished like two months ago, I was thrilled when it gave this very small lemons, but they fell, they didn't stick to the tree, just died

(images 3 to 6)
So I really don´t know what to do to make it growth, it's been my dream to have a real lemon tree, in my country (Mexico) we have a very different lemon, it is a small lime very acid, terrible flavor, the only way I can get real lemons is from Costco...
BTW, I have two different citrus trees in the same backyard growing with no problem, one is this acid lime, and the other is like a sweet lime, they gave many fruits, very nice...
Please Help Me!!!, thanks
