I recently planted some beds with a number of cooler weather greens and root crops, and am wondering if draping a clear plastic sheet over to make a sort of temporary cold frame has been done. My assumption is it would retain the little moisture and heat enough to sprout.
I put some plastic over the frozen mulch pile and within days of doing so I can feel heat coming off it in the morning despite it being 25F at night, so the plastic is helping for sure.
Does anyone do this over carrot or lettuce beds?
I know using actual mulch would probably be best, but I just moved here, and the organic material is completely filled with cold hardy weed seed so I'm gonna let it cook for a while before applying.
Live free or die trying.
