Yes it is. Even in the gardening pots I have, composting happens. I just take the materials to compost, put them in a pot, add a smidgen of organic fertilizer, water well for a few weeks, Viola, compost! No fuss, no mess, no smell. And I have enough organic fertilizer for my garden pots.
Let me see if I understand this. You put your kitchen scraps, etc, in pots, then plant in those pots after the scraps turn into compost? I’m not able to compost any longer because it was attracting bears, dogs, coyotes, mice and who knows what else? I can’t compost inside the fence because my dogs would eat everything. I have to throw all of my kitchen scraps into the trash, which really bothers me. Those composting bins are so expensive.
