I started this season with my own potting mix which was equal parts peat moss, top soil, and mushroom compost. Being my first season I quickly learned that this mix was too heavy and compacted and most plants got moved to a different mix earlier with much improved results. I forgot that I had another plant, a fillius blue, out front in the same mix. It has now started to flower and fruit but it is very wimpy. Should I repot into my much improved mix or would I be better off leaving it in this terrible dwarfing mix? I know the mix it is in now is bad and is holding it back, I just don't know if repotting would do more harm than good now that it has started fruiting. Thanks ahead of time for the help.
