You CAN grow a good crop in MG if you're attentive to how you water and fertilize. It's just easier and more fool-proof in a well-aerated mix that drains freely. I'm not familiar with "MG Fruit and Vegetable Soil", but generally peat-based soils collapse too quickly and are too water retentive to be considered good, when compared to the soils you can build based on pine or some other conifer barks instead of peat. Search this forum using ..... never mind - I'll leave a link below that explains a little about container soils, what is and isn't important ...... ;o)

I think katrina08 is referring to the Miracle Gro "Garden Soil" rather than the Miracle Gro "Potting Soil". I believe it is much finer than the potting mix and holds more water because it is for use on the ground rather than a garden bed. I could be wrong though. I would repot with a custom mix or at least the Potting Soil mix Miracle Gro sells. But then again, it's all about results. If your plants are flourishing, leave them be, but I don't think they would be in potted "garden soil".
