Sowing seed outdoors:

  • Direct sow seeds in average soil in full sun after all danger of frost.
  • Prepare the soil by removing weeds and working organic matter into the top 6-8 inches of soil; then level and smooth.
  • Most plants respond well to soils amended with organic matter. Compost is a wonderful form of organic matter with a good balance of nutrients and an ideal pH level, it can be added to your planting area at any time. If compost is not available, top dress the soil after planting with 1-2 inches of organic mulch, which will begin to breakdown into compost. After the growing season, a soil test will indicate what soil amendments are needed for the following season.
  • Sow seeds 18 inches apart and cover with fine soil.
  • Firm soil lightly, water and keep evenly moist.
  • Seedlings emerge in 10-14 days.

Sowing seed indoors:

  • Sow amaranthus seeds indoors 6-8 weeks before the last frost
  • Sow thinly and evenly and cover with fine seed starting formula.
  • Maintain at a temperature around 60 degrees Fahrenheit.
  • Seedlings emerge in 10-14 days.
  • As soon as seedlings emerge, provide plenty of light on a sunny windowsill or grow seedlings 3-4 inches beneath fluorescent plant lights turned on 16 hours per day, off for 8 hours at night. Raise the lights as the plants grow taller. Incandescent bulbs will not work for this process because they will get too hot. Most plants require a dark period to grow, do not leave lights on for 24 hours.
  • Seedlings do not need much fertilizer, feed when they are 3-4 weeks old using a starter solution (half strength of a complete indoor houseplant food) according to manufacturer’s directions.
  • Transplant after all danger of frost has passed.
  • Before planting in the garden, seedling plants need to be “hardened off”. Accustom young plants to outdoor conditions by moving them to a sheltered place outside for a week. Be sure to protect them from wind and hot sun at first. If frost threatens at night, cover or bring containers indoors, then take them out again in the morning. This hardening off process toughens the plant’s cell structure and reduces transplant shock and scalding.

 

Transplanting to the Garden:

  • Select a location in full sun with good rich well drained organic soil.
  • Prepare the bed by turning the soil under to a depth of 8 inches. Level with a rake to remove clumps of grass and stones.
  • Set plants 18 inches apart in the garden.

 

 

  • Keep weeds under control during the growing season. Weeds compete with plants for water, space and nutrients, so control them by either cultivating often or use a mulch to prevent their seeds from germinating.
  • Mulches also help retain soil moisture and maintain even soil temperatures. For annuals an organic mulch of shredded leaves lends a natural look to the bed and will improve the soil as it breaks down in time. Always keep mulches off a plant’s stems to prevent possible rot.
  • Keep soil evenly moist but not wet.
  • No fertilizer is needed unless the soil is poor. Do not over fertilize.
  • Monitor for pests and diseases. Check with your local Cooperative Extension Service for pest controls recommended for your area.
  • Remove plants after they are killed by frost in fall to avoid disease issues the following year.

  • Plant amaranthus along a fence or a wall as a colorful annual hedge.
  • Massed plants can have a great impact.
