I have such a long post to make about the quantity of plastic used in farming and home gardening. It's so much, and breaking down in the worst possible places. From poly tunnels, tarping to kill cover crops, and large round bales of hay to little starter pots, baling twine, and electronet it's so hard to avoid.
Our hay guy tried sisal twine for baling last year but it broke too often for him to use long term. We're replacing the reused plastic baling twine that ties our metal chicken stops together with the leftover sisal. We use biodegradable pots for starters until we can get a good soil blocker.
Looking at setting up a greenhouse the costs of using anything but poly sheeting or poly siding are astronomical. We have a lot of random glass around from various renovation projects, but not nearly enough to do a sizable greenhouse. I don't think it's going to far to say that the "start a home garden, it will save money" movement is predicated on using cheap plastics right now.
I'm curious how other folks are thinking / feeling about this and novel solutions to reducing plastics in gardening.
