Tangelo losing leaves
I bought my dwarf Tangelo in the summer of 2011. It certainly lost a lot of leaves when I brought it in last winter, but it did manage to produce one fruit. For the first year, I though that was perfectly fine. This winter though, it is much worse. I started out doing what I did last winter, but the leaves kept falling. I moved it into a different room, this one with more light and I watered it about twice a week, sometimes mixing in epsom salt and some generic fertilizer. Unfortunately, the leaves continue to fall and it is looking pretty sparse now. The thing is, it continues to try to produce flowers, they bloom and then usually fall away, although I have a few that have the very beginnings of fruit on them. I put in a miracle grow citrus fertilizer spike today, in the hopes that having more of the proper nutrients, it will do better. Does anyone have any advice? Why was it more or less fine last year, but this year is losing all its leaves? Thanks!
