|Planting Amaranthus Seed
|Sow amaranthus seeds when frost season is completely over and night time temps are close to 50F or warmer. Or, sow the amaranthus seeds indoors about 6 weeks before frost season is over with temperatures between 65 - 75F. Press the amaranthus flower seeds in to soil, but do not cover. Keep flower seeds moist until germination which should be between 10 - 21 days.
