Disclaimer: I’m sure there are just as many ways of doing this as there are gardeners, but this is how I do it. I am by no means an expert, just someone who likes to garden. This is the process that works for me. For more information, I highly recommend you visit WinterSown. You can learn all about winter sowing as well as get free seeds to use in your own winter sowing efforts.
- milk jugs (or cartons, or tall foam cups, or any other container you can re-use that will hold at least 3″ of soil, plus plants)
- good quality potting soil (go ahead and buy the good stuff, you’ll save enough everywhere else)
- heavy duty kitchen shears or a utility knife
- duct tape
- plant markers (optional) and a marker
First I gather a lot of milk jugs and other containers. I don’t like having these sit around all year, so I just ask friends and family to save them for me for about the month before I plant. I always end up with enough. Make sure these are SUPER CLEAN. I wash them out beforehand and then after cutting them to make sure they’re really clean.
