Coverage & Planting Details
| Coverage | This packet sows up to 133 feet. |
|---|---|
| Row Spacing | 12" |
| Seed Depth | 1/8"-1/4" |
| Seed Spacing | A group of 3 seeds every 6" |
| Thinning | When 1" tall, thin to 1 every 6" |
| Germination | 5 – 15 days |
| Start Indoors | 6 to 8 weeks before your average last frost date. Sow in biodegradable pots; roots sensitive to disturbance. |
| Direct Sow | RECOMMENDED. 1 to 2 weeks after your average last frost date; however, grows fastest when temperatures are warm. Soil temperature for germination should be at least 55°F, ideally 68°–75°F. |
| Growing & Harvesting | FOLIAGE: Young leaves have a milder flavor than mature leaves. However, leaves are edible before plant blooms, between 7 and 9 weeks. The iron content of the plant doubles between the 7th and 9th week. SEED: Wait until seeds are mature and dry. Pull up plant and hang upside down in a warm, dry place; when completely dry, shake seed heads into paper bag. Seeds should be stored in an airtight container. One square yard of amaranth can produce 2 pounds of seed! |

- Rowan L.NJ, United StatesVerified ReviewerRated 5 out of 5 stars8/18/26Great summer spinach
Planted in July in full sun, they sprouted fast, beat the heat, and provided a harvest in 8 weeks. Can't ask better than that! And no insect damage. I plan to plant these again next year so I would love to get some advice on how early I can sow, that is, what soil temp I should wait for.

We're so stoked to hear that your Edible Red Leaf Amaranth Seeds have been such a fantastic success! It's awesome that they sprouted fast, handled that July heat so well, and gave you a great harvest in just 8 weeks with no insect damage. That's exactly what we love to see!
The soil temperature (not air temp, but soil temp) for germination should be at least 55°F, ideally 68°–75°F, for direct-sown seeds to germinate. We prefer direct-sowing these into the garden.
In addition, the nighttime air temperatures should be steadily above 50°F. As it's a warm-weather crop, it's best to wait until all danger of spring frost has fully passed, because it will struggle at air temperatures lower than 50.
Unfortunately, we don't know the exact timing of when your nighttime temps will stay over 50, but we do know that on average, there's only a 10% chance of a 32°F frost incident remaining by April 27th. It's a 50% chance on April 11th in your zip code, meaning there's still a 50/50 chance of frost at that time. We suggest waiting until the first week of May to be totally safe, and ideally monitor the weather to see if the nighttime temps stay above 50°F before planting -- or provide some sort of row cover to help insulate the plant from any cooler temps.
If you want to get a jump on the timing, this can be started indoors 6-8 weeks before the average last frost date (which we usually define as a 50% chance of a 32°F frost incident, aka April 11th in your zip code). However, we recommend sowing these in biodegradable pots or handling the transplants carefully, as amaranth can be sensitive to transplant shock, and this isn't our preferred method; it generally does best if direct-sown.
We hope this information is helpful. Thanks so much for being part of the growing community! Keep on growing 🌻
- Phoenix O.Verified BuyerRated 4 out of 5 stars8/11/26Great seeds 4 stars
About half of the seeds sprouted after more or less a week. The seedlings are thriving and have a few true leaves. The leaves look just like they do in the illustration. Im looking forward to using the leaves in the kitchen.

- Laura F.CA, United StatesVerified ReviewerRated 1 out of 5 stars7/25/26Unsuccessful crop for me
Very few germinated, and the few that sprouted did not thrive. I planted them next to lettuce and spinach, in a bed that is protected from the critters, and reseeded several times, but no luck! We live in east San Diego County
