I can't find green, vented plastic bags to put over tomato plants. They used to be available. Any ideas?

They go over tomato cages and the tomatoes grow twice as fast as they do without the bags. They are green bags with holes for ventilation.

You say they go over the cages, they must be pretty big. I have never seen or heard of them. They do have what they call water towers to put around plants and you fill them with water to keep them from freezing.


I use milk cartins with thebottom cut out to keep from freezing. when the tops start growing through the top I take them off and put on the cages. Good luck
