I grew a mango plant from the seed of a grocery store mango fruit about 8 years ago. I've kept it alive through 3 moves, spider mites etc. In all that time it grew about a foot in total with nice long big leaves that keep falling off. As each leaf matures it turns brown from the tips inwards then dies and falls off. Sometimes it turns brown in patches and dies and falls off, but they always die and fall off. Last summer I potted it up into a larger pot with some Sea Soil potting soil and put it outside for the first time over the summer. It got masses of leaves and of course they continued to fall off. When I brought it in last fall, all the leaves fell off over the course of winter until it was a stick, then new leaves started sprouting in Feb. and now it has a lot of new leaves coming in continuously and surprise suprise they are all dying and falling off once they get big. I've tried watering it less, watering it more, feeding it, more light, less light etc etc. Any pointers to try out would be greatly appreciated, it's hung in there like a trooper for so long I want to treat it right and hopefully get it to actually start putting on some height.
