Teff
Eragrostis tef
Teff (Eragrostis tef) is a nutritious grain native to Ethiopia, known for its high protein content and gluten-free properties. This fast-growing grass thrives in warm climates and is valued for its health benefits and versatility in cooking.
Everything it needs
9 essentials at a glance
Watering
Teff requires consistent moisture, especially during germination and early growth.
Water the plants deeply once a week, providing about 1 inch of water. In hotter months, increase frequency to twice a week. Signs of over-watering include yellowing leaves and root rot, while under-watering may cause wilting and stunted growth.
Light
Teff thrives in full sun, requiring at least 6-8 hours of direct sunlight daily.
Ideal placement includes open fields or gardens with unobstructed light. It can tolerate partial shade but may result in reduced growth and yield.
Soil
Teff prefers well-draining sandy loam or loamy soil with a pH range of 6.0 to 7.5.
Good drainage is essential to prevent waterlogging. A recommended potting mix includes a blend of peat, perlite, and compost to enhance drainage and nutrient content.
Humidity
Teff prefers moderate humidity levels, ideally between 40-60%.
To increase humidity, mist the plants regularly or place a humidifier nearby. Signs of humidity stress include leaf curling and browning at the tips.
Temperature
Teff grows best in temperatures between 70-90°F (21-32°C) and is hardy in USDA zones 9-11.
It can tolerate brief periods of heat up to 100°F (38°C) but may suffer in prolonged cold below 50°F (10°C).
Fertilizing
Use a balanced fertilizer with an NPK ratio of 10-10-10 or similar.
Apply every 4-6 weeks during the growing season, starting when seedlings are 4 inches tall. Signs of nutrient deficiency include yellowing leaves and poor growth.
Pruning
Pruning is not generally required for Teff, but removing any dead or damaged leaves can promote better airflow and health.
Use clean, sharp scissors or pruning shears for any necessary cuts.
Repotting
Teff is usually grown directly in the ground, but if grown in pots, repot every 1-2 years or when the roots become root-bound.
Signs it needs repotting include roots growing out of the drainage holes. When repotting, choose a pot 1-2 inches larger in diameter and refresh the potting mix.
Propagation
Teff is typically propagated by seeds.
Sow seeds directly into the soil in spring after the last frost. Plant seeds 1/4 inch deep and space them 1 inch apart. Thin seedlings to 12 inches apart once they are a few inches tall for optimal growth.
When it's unhappy
Yellowing leaves
Why it happens
Often caused by nutrient deficiency or over-watering.
How to fix it
Check soil moisture levels and adjust watering accordingly. Fertilize with a balanced fertilizer if nutrient deficiency is suspected.
Wilting
Why it happens
Typically due to under-watering or extreme heat.
How to fix it
Increase watering frequency and ensure the plants are not exposed to excessive heat without adequate moisture.
Root rot
Why it happens
Caused by over-watering and poor drainage.
How to fix it
Ensure proper drainage and reduce watering frequency. If root rot is suspected, remove affected plants and amend the soil.
Pest infestations (e.g., aphids)
Why it happens
Common in stressed plants or those with poor air circulation.
How to fix it
Inspect plants regularly and treat infestations with insecticidal soap or neem oil.
Poor seed germination
Why it happens
Can be due to old seeds, improper planting depth, or inadequate moisture.
How to fix it
Use fresh seeds, plant them at the correct depth, and maintain consistent moisture until germination.
Care through the year
Spring
In spring, sow Teff seeds directly into the soil after the last frost. Ensure soil is well-prepared and moist for optimal germination.
Summer
During summer, maintain consistent watering, especially in hot weather. Monitor for pests and ensure plants receive full sunlight.
Fall
In fall, harvest Teff when the seed heads turn brown and dry. Cut the plants at the base and allow them to dry further before threshing.
Winter
In winter, if grown in pots, move them indoors to protect from frost. If grown in the ground, cover with mulch to protect the roots from freezing temperatures.
Toxicity & Safety
Teff is non-toxic to pets and children. It is safe for consumption and does not pose any health risks.
