Niger (Guizotia abyssinica)
Also known as: Niger seed, Inga seed, Noog
Niger (Guizotia abyssinica) is an annual shrub grown for its edible oil and seeds which resemble small black sunflower seeds. Attracts birds and the seeds are used worldwide in commercial bird seed. The oil extracted from the seeds has a light nutty flavor. Yellow flowers bloom from summer to fall. Prefers sun to partial shade.

How to Water Niger?
For Guizotia abyssinica, watering should be done until the soil is evenly moist but not waterlogged. The water should be able to penetrate deep into the soil, ensuring that the roots have access to moisture. This generally means around 250 ml per watering session, depending on pot size.

What Is the Ideal Temperature Range for Niger?
Guizotia abyssinica thrives best within an ideal temperature range of 68 to 77 degrees Fahrenheit. Maintaining this temperature ensures optimal growth and blooming. At these temperatures, the plant can efficiently perform photosynthesis and nutrient uptake, leading to robust health and productivity.
What Soil is Best for Niger?
Guizotia abyssinica thrives best in well-draining soils that prevent waterlogging, which can lead to root rot. Ensuring good drainage supports healthy root development and maximizes plant growth and yield. Rich in organic matter, this plant needs soil that can provide necessary nutrients for vigorous growth. The presence of essential nutrients like nitrogen and phosphorus enhances flowering and seed production. While Guizotia abyssinica benefits from well-drained soils, a certain level of moisture retention is critical to sustain the plant during dry spells. This balance supports consistent growth without the risk of drought stress.
How to Fertilize Niger?
For Guizotia abyssinica, it's crucial to provide a balanced amount of nutrients. Use approximately 1 teaspoon of liquid fertilizer per gallon of water. For slow-release fertilizers, scatter about 4-6 tablespoons per plant annually, ensuring it meets the nutritional demands without overloading the soil.
How to Prune Niger?
To prune Guizotia abyssinica, start by identifying and removing dead or damaged stems, preferably with sharp pruning shears to ensure a clean cut. Focus on cutting back overly long branches to maintain a neat, compact shape. Be gentle and considerate to ensure that the plant retains its natural habit while promoting robust growth.

How to Propagate Niger plant?
1
Begin by collecting mature seeds from the Guizotia abyssinica plant. Clean them thoroughly to remove any debris or plant material that could harbor disease.
2
Fill seed trays with a moistened potting mix and evenly sprinkle seeds over the surface. Cover them lightly with a thin layer of soil to protect them from direct sunlight.
3
Place the trays in a warm, bright location to encourage germination, which typically occurs within 1-2 weeks. Once seedlings are large enough to handle, transplant them to individual pots.
How to Repot Niger plant?
1
The best time to repot Guizotia abyssinica is when you notice roots circling the pot or emerging from the drainage holes. Another sign is slowed growth despite adequate light and water. Typically, repotting is optimal just as new growth begins in spring or summer, ensuring the plant quickly establishes in its new home.
2
Opt for a pot that's one size larger than the current one, with adequate drainage holes to prevent waterlogging. The right pot provides room for root growth and ensures healthier development, leading to robust flowering and overall plant vitality.
3
Select a well-draining, nutrient-rich soil mix. This type of soil promotes healthy root development and prevents root rot by allowing excess water to escape efficiently. It supports optimal plant health, encouraging lush growth and vibrant blooms.
