African Bulbine
African Bulbine (Bulbine frutescens) is a clumping and evergreen perennial succulent. Its preferred zone is between USDA 9a to 11b. Growing in a variety of habitats, this plant can be found growing near drainage lines, in rocky outcrops, and in renosterveld. It has soft, broad, grey-green foliage which has a fleshy texture to it. It bears orange or yellow flowers throughout the year and its flowers have unusual, almost bird-like style structures with 6-pointed centers. African Bulbine is easy to care for and can be a great addition to any home.
The best way to water African Bulbine is to wait until the soil around the plant has dried out to the touch. The plant tolerates occasional drought but regular watering is necessary for maximum growth and health. Make sure to use well draining soil and to water the plant deeply but not too frequently.
African Bulbine prefers full sun to part shade. The plant requires plenty of light but should be protected from intense afternoon sunlight. Prolonged or direct exposure to intense sunlight may cause the leaves to develop sunburns and scorch marks.
African Bulbine can handle variety of temperatures from 50 F to 90 F (10 to 32 C). It will best grow in temperatures between 65 and 75 F (18 to 24 C). In cooler temperatures, the plant will need a bit more water.
African Bulbine can tolerate a wide range of humidity levels, from very low to very high. It is best to maintain medium to high levels of humidity around the plant. It can tolerate occasional drops in humidity but dry air may cause browning of the leaves.
African Bulbine requires well-draining, sandy soil that is high in organic matter. The soil should be mixed with sand and/or perlite to ensure good drainage. The pH of the soil should be between 6.5 and 7.5.
African Bulbine can be fertilized with a well-balanced fertilizer every two months during the growing season. Use a water-soluble fertilizer with an NPK ratio of 10-10-10, or if strength is not available, dilute the fertilizer to half the strength. Fertilize in late fell or in spring, before it begins to flower, and then again once it has finished flowering. Stop fertilizing in summer and in late fall as the plant goes in a state of dormancy.
African Bulbine is generally not prone to pests or diseases, but there may be some infestations that cause potential problems if left unchecked. Mealybugs, scale insects, spider mites, and aphids may be a nuisance, and may be spotted under the leaves. In the case of an infestation, be sure to remove any infected stems or leaves and dispose of them carefully. You can wipe the leaves off with alcohol-dampened cotton balls or spray the leaves with a mixture of 2 tablespoons of mild detergent dissolved in one quart of water. Neem oil and other insecticides may also be used.
African Bulbine does not need to be repotted frequently, as it prefers to stay in tight spaces. You should repot the plant when the roots have begun to outgrow its pot. Make sure to use a well-draining soil and only move into a slightly larger pot.
African Bulbine does not require much pruning, aside from the occasional deadheading of spent flowers. If necessary, trim off any dead or diseased stems, which will help the plant to remain healthy. Make sure to use sharp, sterile pruners when doing any major pruning.
African Bulbine benefits from additional mulch such as pine needles or wood chips. This will help to protect the root system and will also help to retain moisture in the soil while providing additional nutrients.
African Bulbine can be propagated using seed, division, or stem cuttings. Stem cuttings can be taken in the spring or summer and can be planted directly into moist, well-draining soil. Seeds should be started in a warm location, with plenty of sunlight and a moist soil. Division should be done in the fall or spring, and the clump should be divided by cutting into several sections and then replanting.
African Bulbine does not need much support, however if the stems are long or if the plant becomes very large, it can be helpful to provide some support such as a stake or trellis.
African Bulbine does not require a rest period but may do well with one, depending on the climate. If temperatures dip below 45 F (7 C), the plant should be moved indoors and be given a period of rest. Give the plant plenty of sunlight, water when necessary, and provide a slightly cooler temperature.
African Bulbine is not known to be toxic to pets.
