Seed tapes can be made year round. All it takes is some tape, flour glue and seeds. And it's great for very little seeds that like some spacing, like carrots, beets, lettuce, spinach, radishes..
What you need:
Flour and water for glue. The consistency depends on the seed. Bigger seeds like beets, some spinach or radishes need a thicker glue. Smaller seed like carrots or lettuce can use a thinner glue.
Cheap paper, like cheap toilet paper, paper towels, or crepe paper streamers left over from whatever.
Seeds! That whole bucket is seeds I want to keep making seed tapes with.
A little dish to pour your seeds into. Makes picking them up much easier.
A marker- to write the seed name on the paper with.
Something to work on. I'm using a brown paper bag here. markers can write through the paper super easy, and the flour glue can seep in pretty quick too.
And lastly, something to lay the tapes on while drying. I'm using a stack of cooling racks, but you can use paper bags or news papers. Keep in mind those tapes have to lay till dry, which can take several hours.
When time comes to plant the seed, just lay it down, cover it with a thin layer of dirt to keep the paper in place and give the seeds their proper planting depth. Water in well and treat it like any other direct seeding.
Some notes on flour. You can use any kind of flour. I've used wheat and found it made a thicker glue, good for beet seeds. If you want to, you can add food coloring to your flour when you make your tapes to help you ID them :) Or just make making seed tapes more fun for kids.
You can do this any time of year. It's kind of nice to do them in the winter when there's no hope of any gardening, but you can still feel like you are planting seeds.. sort of...
