It’s difficult to space tiny seeds, such as carrots, in the garden. The best way to solve this problem is to make homemade seed tape. Here’s how to do it:
1. Unroll a strip of toilet paper on a table (double ply works best), mist it with a sprayer, and place the seeds along the center of the strip. Be sure to space the seeds based on the seed packet’s recommendation. Tip: Alternate carrot seeds with radish seeds because when the radishes sprout, they help to mark the row and break the ground.
2. Starting along the strip’s long edge, fold a third of the paper over the seeds, then fold the other third over to cover the seeds completely. Lightly tamp the paper, misting it again to secure the seeds. Make as many of these strips as you need. Then carefully carry them to the garden.
3. Make shallow furrows in the prepared soil, lay the strips down, and cover them. In a jiffy, your small seeds will be planted and perfectly spaced.
