bet you would get a very specific answer in the houseplant or fern forum ...

personally .. i would never use any media.. that already has the fert in it ...

how do they know every plant will appreciate what they put in ???

ken

Not all MG has fert in it, but I would agree, also worrying it might not be evenly mixed or too strong for house plants - or I'll forget and fertilize when fert'ing other plants. If all your plants are in that, the last wouldn't be a concern for you. The issues folks can have with peaty potting soil usually take more than a few months to manifest, so, worst-case-scenario, you won't like it and can change it again in the spring. Compared to having its' roots crammed/with no soil, the fern would probably pick the MG even if something else might be preferable. Ferns aren't that picky, IMHO/E. FWIW, I put a few plants in the ground last spring and they stayed evergreen, through a winter-low of 25 here. Same thing at my Mom's house a few miles away. They seem to be much more concerned about not drying out.

ok i did it the miracel grow is oldish so i am using organic fert like worm castings and coffee grounds they are doing awsome
