Ever notice how you think something must be good and it turns out bad? Bonnie Plants sells their Tomato plants, peppers etc in peat pots which in itself is a great thing- you plant the plant in its pot in the ground and the pot composts itself, fertilizing the ground around the plant. Just throw away the little plastic collar around the pulp pot. BUT- Bonnie plants are in Alabama. I think unless you live in the south, this would make the carbon footprint of the plant something awful.
Now I am not faulting Bonnie plants at all. They have come up with an ingenious answer to an old problem- the plastic starter packs. And for that they deserve a truckload of credit. But it makes me wonder why other plant nurseries don't do the same thing. I have a hard time believing that the plastic starter pots are that much cheaper. And what about the disposal costs? But I suppose they don't have to throw them away so they don't pay disposal costs.
You can make these at home your self by starting plants using Diy starter pots or toilet paper tubes or even egg shells!
