Hi folks, last year when we moved into our first house we bought this lime tree at Lowes. We planted it and dont really know what kind it is. All we know is that it made it thru last winter and is at least twice as tall as it was then (it's 6' tall now). It is huge compared to how it was last year... I mulched it recently, I gave it some shrub fertalizer a few times this last year. Now I am attached to it and I want it to thrive. My main question is should I prune down the leaves so it looks more like a tree than a bush? It hasn't produced anything at all so far. I am planning to cover it wuth a light and a sheet for the frosts this winter because I don't want to lose it. I'll take any advice on this tree you all can give me. I want this baby to give me limes this summer!
