Why do you need miraclegrow potting soil? Take a little time and patience and grow them with normal (sterile) potting soil... unless of course, the local (one and only) grocery is closing down tomorrow. Just kidding. I'm not sure what's the rush but I personally don't use any fertilizer at all, not even organic on the plants I eat. If they need new nutrients (growth lagging and soil looks dried and cakey or maxed out), I change the soil - without upsetting the roots too much. I'm talking about container veggies/herbs though.
I hear they make organic miracle grow veggie soil now. Best to compost if you can though...possibly set up a mini-worm farm. Nature makes the best dirt, I'd say.
OK Several questions why would it not be safe for vegans? all dirt and soil is safe for vegans now there is a difference in vegan and organic obviously it may not be safe for organic if it has chemicals in it I personally have a mulch pile and thats how I grow my vegetables I have done the worm garden in the past and that is good as well the other question is how is peat moss not nice for the enviroment? peatmoss is a naturally occouring plant.
Different folks have a variety of problems with the use of peat moss. I don't use it because it is soooo acidic. pH of 3.0 to 4.5. Some folks have a problem with the way and how much is "harvested". Peace, poor_old_dad
I was in a hurry to get some Japanese persimmons big enough to bare fruit. So to jump start the trees. I filled a half a 50 gallon drum half way up with leaves and worm casting. The rest with miracle grow potting soil. I grew the trees for one year in the barrels. They grew at an outstanding rate. The next year I planted them in the yard. The stuff is great for a quick start, but it dose have chemical fertilizers in it. That's not good, I don't think it would be good for the long haul, but it is good for jump starting plants you are in a hurry for.
Peat harvesting harms the wetlands that keep our planet clean and healthy. It takes a very long time for sphagnum moss to regrow and then decay into peatmoss after the wetlands have been mined or harvested of peat (unless you read that one study that was paid for by the peat harvesting companies in Canada).
