You plant the entire strip in a furrow, cowl it with soil, water it, and the paper dissolves. The seeds germinate proper the place you positioned them, already on the appropriate spacing.
No thinning. No guesswork. No stooping over a row making an attempt to select up one tiny seed at a time.
A Temporary Historical past of Seed Tape
Industrial seed tape has been bought since at the very least the Seventies, when seed firms started on the lookout for methods to make gardening extra accessible to freshmen. Early merchandise had been marketed closely towards suburban and small-space gardeners who had been intimidated by seed sowing. By the Eighties, main seed firms like Burpee and Park Seed supplied pre-made tapes for carrots, radishes, lettuce, and different fine-seeded crops.
The idea itself is older. Japanese market gardeners had been utilizing paper-based seeding techniques within the early twentieth century to enhance effectivity in intensive manufacturing beds. The thought of embedding seeds in a matrix to regulate placement and shield germination was additionally utilized in large-scale agriculture lengthy earlier than it reached the house backyard market.
Right now, seed tape and seed mats are bought by dozens of firms, however they’re costly for what they’re—a skinny strip of paper and some seeds. Making your personal at dwelling is way cheaper, provides you full management over seed selection and spacing, and is a satisfying winter mission whenever you’re itching to do one thing garden-related.
Why You May Need to Make Seed Tape
Seed tape isn’t for each crop or each gardener, however for sure conditions it’s genuinely helpful.
It’s best for tiny, hard-to-handle seeds. Carrots, lettuce, radishes, beets, and onions are infamous for being troublesome to sow thinly. A shaky hand or a gust of wind can scatter them into an unusable clump. Seed tape solves this completely.

Easy methods to Make Seed Tape: What You Want
The supplies are easy and also you probably have most of them already.
- Rest room paper or paper towels. Single-ply bathroom paper is good. It dissolves rapidly in soil and is skinny sufficient to not impede germination. Paper towels work however decompose extra slowly.
- All-purpose flour and water. Blended into a skinny paste, that is your seed adhesive. It’s utterly biodegradable and gained’t hurt seeds or soil. One tablespoon of flour to 2 tablespoons of water is about proper. You need it thick sufficient to carry a seed however skinny sufficient to unfold simply.
- Seeds. Finest candidates: carrots, radishes, lettuce, spinach, beets, onions, parsnips, and some other small-seeded crop. Giant seeds like beans, squash, and corn don’t profit a lot from seed tape.
- A toothpick or skewer. For selecting up and putting particular person seeds.

- A pen or pencil. For labeling your tapes and marking spacing on the paper.
- A flat floor lined with newspaper or parchment. So your tapes can dry with out sticking.
Step-by-Step Directions
Step 1: Test Your Seed Packet for Spacing Necessities
Earlier than you do anything, examine the again of your seed packet for the beneficial in-row spacing. That is the quantity you’ll use to mark your tape. Carrots, for instance, are sometimes spaced 2–3 inches aside. Lettuce can go from 3–8 inches, relying on whether or not you need full heads or cut-and-come-again harvests.
Write the crop title, selection, and spacing instantly on the bathroom paper with a pencil or pen earlier than you begin so that you don’t neglect which selection you taped. The label will dissolve harmlessly within the soil together with all the things else.
Step 2: Combine the Paste
In a small bowl, combine 1 tablespoon of all-purpose flour with 2 tablespoons of water. (You can even use gluten-free flour or cornstarch if it is advisable.) Stir till easy and lump-free. The consistency ought to be just like a thick college glue: It wants to carry a small seed in place whereas it dries, however not so thick that it smothers germination or leaves a heavy residue.
If the paste appears too runny, add a bit extra flour. If it’s too thick and gummy, skinny it with just a few drops of water. You don’t want a lot—a tablespoon of paste will make a number of ft of seed tape.
Step 3: Mark Your Spacing on the Rest room Paper
Tear off a strip of bathroom paper to your required row size—12 to 18 inches is a manageable working size for square-foot gardening beds, however you may make them so long as your rows for row gardening. Lay the strip flat in your work floor.
Lower the bathroom paper lengthwise with scissors into two or three strips of equal size. In case you are utilizing bigger seeds, minimize two 2″ strips. In case you are utilizing tiny seeds, minimize three or 4 narrower strips.
Utilizing a pencil and ruler, make small dots at your spacing intervals alongside the middle of the strip. For carrots at 2-inch spacing on a 12-inch strip, you’d make 6 dots. These dots are simply guides—they don’t should be exact to the millimeter.
Step 4: Apply the Paste and Place the Seeds
Dip a toothpick into the flour paste and dab a small drop onto every pencil mark in your strip. The drop ought to be in regards to the measurement of the seed you’re utilizing—simply sufficient to stick it with out burying it in paste.
Then, utilizing the identical toothpick or a clear one, decide up a seed by moistening the tip barely and urgent it towards the seed. Place it on the paste dot and press gently. The seed will stick. Work your method down the strip one seed at a time.
For previous or specialty seeds that may have a decrease germination charge, you possibly can place 2–3 seeds per dot. You possibly can all the time skinny to the strongest seedling as soon as they sprout, however having a backup ensures you don’t find yourself with naked gaps in your row.
Non-compulsory: Fold and Seal for Heavier Seeds
For small, light-weight seeds like carrots or lettuce, a single layer of bathroom paper is all you want. However in case you’re making tape for barely bigger or heavier seeds—spinach, beets, parsnips, or Swiss chard—a folded tape holds them extra securely and makes dealing with simpler.
To do that, run a skinny line of paste alongside the whole size of the strip on one facet, then fold the strip in half lengthwise so the 2 edges meet, sandwiching the seeds inside. Press the sides collectively gently and easy the tape flat. The seeds are actually enclosed between two layers of paper, which additionally protects them barely throughout storage and makes the tape a bit extra sturdy in case you’re dealing with lengthy strips.
The 2-layer tape takes a bit longer to dissolve in soil, however for single-ply bathroom paper the distinction is negligible. Skip this step for very positive seeds like carrots or lettuce as a result of the fold can shift them out of place earlier than the paste units.

As soon as dry, you possibly can loosely roll every tape and label it with the crop title, selection, spacing, and the date it was made. Retailer in a cool, dry place away from humidity. A repurposed cardboard tube or a paper envelope works properly.
Step 6: Plant Your Seed Tape
If you’re able to plant, put together your mattress as standard. Make a shallow furrow on the depth beneficial in your seed packet—sometimes ¼ to ½ inch for many small-seeded crops.
Lay the seed tape within the furrow seed-side down, cowl with soil, and agency gently. Water properly. The paper will start to dissolve throughout the first watering and can be utterly gone inside just a few days. Your seeds gained’t know the distinction.
In case your tape is longer than your furrow, merely fold it again on itself and proceed — the additional layers of paper are skinny sufficient that germination gained’t be affected.
Suggestions and Troubleshooting
Use single-ply bathroom paper at any time when doable. Two-ply can sluggish germination barely as a result of it takes longer to interrupt down. If all you might have is two-ply, separate the layers earlier than you begin.
Don’t use glue sticks or craft glue. Many adhesives comprise chemical substances that may inhibit germination or persist in soil. Flour paste is the most secure, most dependable possibility.
Outdated seeds work positive on tape. Seed tape is an efficient method to make use of seeds from earlier years which have marginal germination charges. Place 2 seeds per dot as a substitute of 1 to compensate for decrease viability.
Make a batch directly. On a winter afternoon, make all of the tapes you’ll want for the season. Carrots, beets, radishes, lettuce, spinach — knock all of them out directly. They’ll maintain for months in a cool, dry spot.
Seed tape works properly in containers. Lower tapes to suit your pot or raised mattress precisely. No extra guessing whether or not you’ve overseeded a small area.

- Radishes — Quick-growing, simple to oversow. Area 1–2 inches aside.
- Lettuce — Nice for making cut-and-come-again rows. Area 4–6 inches aside for leaf sorts, 8 inches for heads.
- Spinach — Small seeds which can be simple to oversow. Area 3–4 inches aside.
- Beets — Every ‘seed’ is definitely a cluster of two–4 seeds, which is why thinning beets is such a chore. Place 1 cluster per dot at 3–4 inch spacing.
- Onions (from seed) — Extraordinarily positive seed. Area 3–4 inches aside.
- Parsnips — Notoriously poor germination and troublesome to skinny. Place 2–3 seeds per dot at 3-inch spacing.
