Mr. mm is planning on using some of our old windows to make a cold frame for the spring. We have some pretty big old ones that would work nicely to get a start on the cold sensitive plants. Since we can’t count on not getting a frost until even early June, we could EASILY gain more than a month of growing season by being able to protect them like that.
We also have lots of old curtains and mattress pads stored in the barn that we could cover the cold frames with to help hold in heat if worse comes to worse.
Sometimes I hate all the clutter from storing stuff, but we have what we need and don’t have to go out and waste money buying it.
Two important things.
Plants like warm feet. If you can get the soil warmed, they will do better.
Empty soda bottles (3 liter) work really well as caps. Just cut out the bottom. You plant the seedling and pop a bottle on top of it. If you feel you need the top, it is too cold to plant.
