Seed tape is a paper-thin strip with seeds embedded (and mostly evenly spaced) into the nearly translucent strip of paper. The concept behind seed tape is to facilitate easier planting and spacing of tricky small seeds, and to prevent the need to thin later in the season. Seed is distributed evenly throughout the length of the seed tape. While very convenient and productive it is a luxury that a homeowner should be willing to pay for, and to accept that seed tape will not come in the diversity of varieties available in seed form. Seeds available in seed tape can include lettuce, chard, carrots, onions, radishes, beets and more. Seed tape or cloth is also available for flowers.
To plant, simply follow the instructions on the package and sow the strips in the ground or in containers. If using a container cut the strips to size. After placing, cover the seed strips with 1/8-1/4” of soil or potting media, usually the seed packet will provide more precise planting depth requirements. Water well and wait for a uniform crop free from the need to thin. Once the seeds have germinated treat them like any other plant in your garden or container garden.
