Simple DIY. I actually saw seed tape for sale at a big box store a few weeks ago. I sort of laughed at the price...
Its easy to make if you don't mind being a little nit-picky.
I don't like to thin, so i rarely sow direct because when i do i tend to oversow and annoy myself.
So here's how i do it.
Paper towel.... 2 ply is great, the cheapest is actually better than what i have because it is thin.
Don't separate the ply right yet, it will save work later if you don't. If you want narrow rows use a mid grade TP.
Get a ruler, glue, pencil and a felt marker and seeds.
check the spacing of the seeds and get ready to mark your grid.
I'm spacing mine closer since i plan to harvest them small... my garden soil is not very deep so i can't expect long roots at all.
This is why i leave the ply intact until marking is finished and use a felt pen. Saved half the effort.
I have even gotten this marker to mark through 4 layers of ply, but 6 seems too much...or i would need a juicier marker.
So now i separate the ply.
Running out of room at the edge is ok because you can overlap them in the garden to keep relatively even rows
Tiny carrot seeds, these are Cosmic Purple. (funny, they don't look purple- lol)
.Tedious, but i'd rather do this comfortably seated at the kitchen table than bent over a row with the wind blowing everything to kingdom come.
The lick-a-toothpick method works great for this.
Label it so it won't get mixed up.
Lay them aside separately to dry or they will stick together if the glue spots touch. I think that would make a huge mess of the situation!
I'll put these in the garden once i get them all finished. I want at least6 squares of paper towel in size for each variety.
But it does take time to make them...
Its good to let them dry completely, just so they don't stick to each other. Try to do this on a still day... In the last few years i have found my home to be on one of the breeziest areas i have ever known. Its almost constant and just strong enough to be irritating.
But anyway, spray down the dirt. It gives the paper something to adhere to immediately so you have an extra split second to grab a few clods of handful of dirt before the breeze picks it up.
This is actually the last sheet of seeds, the rest you can see are covered in dry dirt. The wind was being too pesky for me to take the time to grab the camera.
So, i covered the covered and well watered seed tapes with plywood boards and i hope those don't blow away!
