How to grow
How To Grow Amaranthus From Seed: In areas with a long growing season, start Amaranthus seeds directly outside in a prepared seedbed after frost season is over. To get a jump start on the growing season, Amaranthus flower seed can be started indoors.
Start seed indoors 6 - 8 weeks before the last frost is expected and then transplanted outdoors. Amaranthus plants grow best in full sun. They prefer moderately fertile, moist soil with lots of organic matter. During dry spells, water freely to prolong the flowering period.
- Sowing Rate: 4 - 5 seeds per plant
- Average Germ Time: 10 - 21 days
- Keep moist until germination
- Attracts bees and butterflies
- Depth: Press into soil, do not cover
