Cultivation Methods
Blepharis integrifolia (L.f.) E.Mey. ex Schinz var. setosa (Nees) Oberm., commonly known as African forest sugarbush, is a plant that thrives in warm temperatures. It is adaptable to a wide range of soil types, including sandy soils, loamy soils, and rocky soils. It also tolerates a wide range of soil pH levels. Planting in full sunlight is recommended, but it can also grow in partial shade. To facilitate proper growth, the plant requires well-draining soil that is rich in organic matter.
Watering Needs
The African forest sugarbush requires moderate watering throughout its growing season, which is usually spring and summer. The plant should be watered once a week, and the soil should be allowed to dry between watering. During the winter season, watering should be reduced to once every two weeks. Overwatering should be avoided as it can cause root rot and other fungal diseases.

Fertilizers should be applied during the growing season, and it should be applied every four to six weeks. Alternatively, the plant can also be fed with organic fertilizers such as compost tea, fish emulsion, or bone meal, which provide a slow-release of nutrients that are essential for plant growth.
Pruning
Pruning is one of the essential maintenance tasks to ensure the African forest sugarbush remains in proper shape. Blepharis integrifolia can be pruned to stimulate new growth, remove dead or diseased foliage, or control its height. Ideally, pruning should be done in late winter or early spring before the new growth begins. To prune the plant, use a clean, sharp pair of pruning shears and make sure to cut at an angle to prevent water from settling on the cut area.
Propagation of Blepharis integrifolia var. setosa
Blepharis integrifolia var. setosa can be propagated through various methods. The commonly used methods are:
Seed Propagation

The seeds can be directly sown in the soil, or they can be raised in a nursery and transplanted later. The seedlings should be watered regularly and kept in a shaded area till they are ready for transplanting.
Cutting Propagation
Blepharis integrifolia var. setosa can also be propagated through cuttings. The stem cuttings are taken from a mature plant and should be around 10-15 cm long. The cuttings should be dipped in rooting hormone and planted in a potting mix. The potting mix should be kept moist, and the cuttings should be kept in a shaded area. The cuttings will take around 4-6 weeks to root. Once the roots have formed, the plant can be transplanted to a bigger pot or in the ground.
Division
Division is another great method for propagating Blepharis integrifolia var. setosa. The plant should be carefully lifted from the soil and the root ball should be divided into two or more sections. Each section should have a healthy root system and a few stems. The sections can then be planted in individual pots or directly in the soil. The plants should be watered regularly and kept in a shaded area till they establish themselves.
