Quinoa

Chenopodium quinoa

Quinoa is part of the Chenopodium genus. Its scientific name is Chenopodium quinoa.

Grown for its edible seeds and leaves, Quinoa is a grain that has been to known to be cultivated for at least 5000-6000 years continually.1


Rinse seeds and leaves thoroughly before eating as both contain saponin, a toxin. The toxin however is usually present in such small quantities that it has an extremely little chance of doing any harm. Don’t eat leaves to excess to avoid any ill-effects from the saponin.


To prepare the grains for eating, place in a water bath for 1-2 hours, rinsing and changing the water 1-2 times. Other methods include placing grain in a cheesecloth or fine strainer and placing it under running water to remove the saponin. 1


Quinoa can be prepared like rice, although for a more al dente texture, mix equal parts quinoa and water.

It is a flowering edible herb / vegetable that typically grows as an annual, which is defined as a plant that matures and completes its lifecycle over the course of a single year. Quinoa is known for its forb habit and growing to a height of approximately 1.20 metres (3.90 feet). This plant tends to bloom in mid summer, followed by first harvests in late summer.

Chile is believed to be where Quinoa originates from.

Quinoa is normally fairly low maintenance and is normally quite easy to grow, as long as a level of basic care is provided throughout the year. Being aware of the basic soil, sun and water preferences will result in a happier and healthier plant.

How to grow Quinoa

  • Full Sun

    OR +
  • Partial Sun

    +
  • Low

Once plants mature, they are more tolerant of dry conditions, but younger plants require more regular watering.

Try to plant in a location that enjoys full sun / partial sun and remember to apply water fairly sparingly. Use Zone 3 - Zone 10 as your guideline for the appropriate climate for this plant. Quinoa needs a loamy soil with a ph of 6.0 to 8.5 (weakly acidic soil - weakly alkaline soil). Keep in mind when planting that Quinoa is thought of as tender, so remember to wait until your soil is warm and the night time temperature is well above freezing before moving outside.

Growing Quinoa from seed

Try to aim for a seed spacing of at least 5.85 inches (15.0 cm) and sow at a depth of around 0.23 inches (0.6 cm). Soil temperature should be kept higher than 10°C / 50°F to ensure good germination.

Transplanting Quinoa

Ensure that temperatures are mild and all chance of frost has passed before planting out, as Quinoa is a tender plant.

Harvesting Quinoa

Harvest any time after seeds have changed from green to their calico colors, even after light frost. Rain near harvest time will cause problems since mature seed will start to germinate.1

Seed Saving Quinoa

Store seed dry to prevent germination.1
