In recent years, teff has gained recognition outside of East Africa, especially due to the growing popularity of gluten-free foods. With its high nutritional content and versatile uses, teff is now grown in countries around the world, including the United States, Canada, and parts of Europe. As more people seek healthy alternatives to traditional grains, teff’s profile continues to rise.

Botanical Description

Teff is a warm-season grass that grows to a height of 3 to 5 feet (about 1 to 1.5 meters). It has thin, narrow leaves and delicate flowering heads that contain a large number of tiny seeds, each roughly the size of a pinhead. Despite the small size of the grain, teff is packed with nutrients such as protein, fiber, calcium, iron, and other essential minerals.

Teff plants thrive in dry, semi-arid climates and are well-suited for cultivation in Ethiopia's highland regions, where they have been grown for centuries. The seeds are typically light brown, red, or white, and the grain is harvested when the plant is fully mature and the seeds are dry.

Teff is valued not just for its edible grain but also for its straw, which can be used as animal fodder. The plant is well-adapted to harsh growing conditions and can tolerate drought, poor soil, and high altitudes. It is a relatively low-maintenance crop that requires minimal water once established, making it an ideal plant for sustainable agriculture in areas with limited resources.

Growing Instructions

Teff is a relatively easy plant to grow, although it does require specific conditions for optimal growth. Here are some important growing instructions to keep in mind when cultivating teff:

Sunlight: Teff requires full sun to grow properly. It should receive at least 6–8 hours of direct sunlight per day. A sunny location is essential for the plant to thrive and produce high-quality grain.

Soil: Teff grows best in well-draining soil that is rich in organic matter. The plant is quite adaptable to different soil types, but it prefers slightly acidic to neutral soil with a pH range of 5.5 to 7.5. To improve soil quality, you can incorporate compost or organic fertilizers before planting. Although teff can tolerate a variety of soil types, it does best in soils that are light and loamy, providing adequate drainage while holding moisture. Heavy clay soils should be avoided, as they can lead to poor root growth and waterlogged conditions.

Temperature: Teff is a warm-season plant that thrives in temperatures between 75°F and 90°F (24°C to 32°C). It is highly sensitive to frost and cannot tolerate cold temperatures. The plant requires a long, warm growing season to reach maturity, typically between 90 to 120 days.

In regions with cooler climates, teff may need to be grown as a warm-season crop, planted after the last frost date. It is possible to grow teff in containers indoors in cooler climates, as long as it receives plenty of sunlight and warm temperatures.

Watering: Teff plants are drought-tolerant once established but do require regular watering during the early stages of growth. Consistent moisture is important for proper germination and to support the growth of the young plants. Once the plants are established, they can tolerate periods of dry weather, making them ideal for areas with limited water availability.

However, like most grains, teff does not thrive in waterlogged conditions. It is important to ensure good drainage and avoid overwatering, especially in areas with heavy rainfall or poorly draining soils.

Spacing: Teff plants should be spaced about 6–8 inches (15–20 cm) apart when planting. This allows enough room for the plants to spread out and ensures proper air circulation, reducing the risk of diseases and pests. If growing teff in rows, space the rows 12–18 inches (30–45 cm) apart to provide ample space for growth.

Pruning: Teff does not require heavy pruning. However, if growing the plant for its straw (used for animal fodder), you can trim back any excess growth after the seeds have been harvested. The plant can be cut down once the grain has been fully harvested and the seeds have dried.

Support: Teff is a tall, slender grass-type plant that does not require support.

Life Cycle: Teff has a relatively short life cycle compared to many other grains, which makes it an excellent choice for regions with short growing seasons. Here's an overview of the different stages of teff's life cycle:

• Germination: Teff seeds are small but highly resilient. They typically germinate within 5–10 days of planting when the soil is kept consistently moist and the temperature is warm. Teff is typically direct-seeded, meaning the seeds are planted directly into the soil rather than being started indoors.

• Vegetative Growth: Once the seeds have germinated, the teff plants enter the vegetative growth phase. During this time, the plants grow rapidly, developing long, slender stems and narrow leaves. This stage usually lasts for about 3–4 weeks, depending on growing conditions.

• Flowering: Teff flowers are small and typically green or purple in color. The flowering stage begins about 40–50 days after planting and lasts for 2–3 weeks. The flowers eventually turn into seed heads that will produce the edible grains.

• Fruit Set: After the flowers bloom, the plant produces seeds that mature within 40–50 days. The grains are very small, resembling a fine sand-like texture. These seeds are ready for harvest once they have fully matured and dried.

• End of Season: Teff is an annual plant, meaning it completes its life cycle in one growing season. After the grain has been harvested, the plant will naturally die off. However, the seeds can be saved and replanted for the next season.

Harvesting and Foraging

Harvesting: Teff is harvested when the seed heads turn golden brown and the seeds are dry. At this stage, the plants are typically cut at the base, and the seed heads are collected. Because teff grains are very small, harvesting requires some care. The plants may be harvested by hand or using specialized harvesting equipment. Once harvested, the seeds must be separated from the chaff, which can be done by threshing. The seeds should then be cleaned and dried further before storage. Harvesting teff in dry weather is ideal, as it helps to prevent mold or mildew from affecting the grain.

Foraging: Teff is not commonly foraged in the wild, as it is primarily grown as a cultivated crop. However, wild relatives of teff may be found in certain parts of Africa, where they have similar nutritional properties. If you are foraging for wild grasses or seeds, it's important to correctly identify the plants and ensure they are safe to eat.

Plant Companions

Teff benefits from companion planting with other crops that improve soil fertility or provide some shade. Good plant companions for teff include:

• Legumes (e.g., beans or peas): These plants are nitrogen-fixers and can help improve the soil quality around teff, leading to better growth.

• Corn: Corn plants can help provide some shade for teff, protecting it from excessive heat, especially during the hottest months.

• Lettuce or other leafy greens: These plants can help shade the soil and reduce weed competition around teff.

Common Pests and Diseases

Pests: Teff is relatively resistant to pests but can occasionally suffer from damage caused by aphids, grasshoppers, or weevils. Organic insecticides or natural predators like ladybugs can help control pest populations. Additionally, removing any affected plants or plant debris can help reduce pest infestations.

Diseases: Teff can sometimes be susceptible to fungal diseases like smut or rust, which can affect the plant’s leaves and seeds. To reduce the risk of disease, make sure that teff is grown in well-drained soil and that the plants have good air circulation. Avoid overwatering and ensure that the plants are spaced adequately.

Shopping Tips

When purchasing teff, look for organic varieties to ensure the grain is free from harmful pesticides. Teff seeds can be found in most health food stores or specialty markets, particularly those that cater to gluten-free products.
