Growing in Pots, Balconies & Indoors

Red amaranth (Amaranthus cruentus) is a tall annual, 0.8-2 m, grown for grain and edible leaves. The grower does not treat it as a houseplant, but it grows well in a 5-8 L pot on a sunny balcony or patio.

Quick Details

  • Container Size: 5-8 L (1.5-2 gal) – the grower’s guide
  • Indoor Suitability: Not a houseplant – a tall, sun-loving annual
  • Best Spot: Full sun (part sun only reduces flowering)
  • Soil & Drainage: Well-ventilated, organic-rich mix with good drainage (grower)
  • Watering in Pots: Average needs – keep the soil moist, helped by mulch (grower)

Indoors & On the Windowsill

  • Houseplant: No – the grower marks it as not an indoor plant; it needs full sun and grows tall.
  • Windowsill growing: Only for raising seedlings on a sunny sill before planting out.

On a Balcony or Patio

  • Light & wind: Give it full sun (a little less only trades some flowering); tall types catch the wind, so stake or shelter them. Pots in sun dry fast – the grower’s mulch tip helps hold moisture.
  • Practicalities: A stable pot keeps top-heavy plants upright; easy to move while young.

Choosing the Pot, Soil & Long-Term Care

  • Pot & drainage: A 5-8 L (1.5-2 gal) pot (the grower’s size) with strong drainage holes; Use a pot with strong drainage holes and skip a standing-water saucer to avoid root rot; terracotta breathes and dries out faster, while glazed or plastic pots hold moisture longer.
  • Potting mix: The grower advises a well-ventilated, well-drained mix rich in organic matter – potting mix or peat soil with perlite or vermiculite.
  • Feeding: Potted plants use up their soil quickly because watering leaches nutrients away, so feed a little more often than plants in open ground through the growing season.
  • Season: As an annual it finishes in one season, so start each new crop in fresh mix rather than repotting.

Grower’s Container Tip

  • Mulch to hold moisture: The grower advises mulching the surface of the pot to keep the soil moist and cut water loss, and watching that the mix stays evenly moist.
