If planting multiple plants, space them apart at least 18–24 inches to give them room to grow and prevent overcrowding.
Watering Needs of Bulliarda brevifolia Eckl. & Zeyh.
Bulliarda brevifolia Eckl. & Zeyh. requires moderate watering. Water the plant deeply and less frequently to prevent overwatering. Regular watering is necessary during the first few weeks after planting to encourage root growth. After that, reduce the frequency of watering but increase the amount of water per watering session.
It is essential to monitor the soil moisture level to prevent the plant from drying out or being saturated with water. The best time to water is early morning or late afternoon when temperatures are cooler and the water has time to penetrate the soil before evaporating.
Fertilization of Bulliarda brevifolia Eckl. & Zeyh.
Bulliarda brevifolia Eckl. & Zeyh. requires minimal fertilizer. In fact, over-fertilizing can damage the plant. Fertilize the soil with a balanced, slow-release fertilizer at the beginning of the growing season. Avoid applying fertilizer to dry soil, as this can burn the plant's roots.
Depending on the soil quality, you can add bone meal or compost instead of chemical fertilizers. Bone meal is rich in phosphorus, which promotes flowering and strong root development.
Pruning of Bulliarda brevifolia Eckl. & Zeyh.
Pruning Bulliarda brevifolia Eckl. & Zeyh. is not necessary, as this plant does not require regular pruning. However, if the plant becomes too bushy or if dead or diseased foliage is present, prune in early spring before new growth appears.
Prune only the affected areas and avoid pruning more than one-third of the plant at once. Use clean, sharp pruning shears to prevent damage to the plant and ensure quick healing of the cuts.
Propagation of Bulliarda brevifolia Eckl. & Zeyh.
Bulliarda brevifolia Eckl. & Zeyh., also known as "short-leaved bulliarda," can be propagated using various methods such as seeds and cuttings.
Propagation by Seeds
The following steps can be followed to propagate Bulliarda brevifolia using its seeds:
- Collect ripened seeds from the plant during the flowering season. The seeds can be stored in dry and cool conditions until the next season.
- Prepare a seed bed with light sandy soil, tilling the soil to remove any weeds and debris.
- Sow the seeds in rows on top of the soil, spacing them at least one meter apart.
- Water the soil regularly, keeping it moist but not waterlogged. Germination should occur within two to three weeks.
- Thinning should be done when the plants reach at least 5 cm in height, maintaining a distance of about 1 meter between plants.
- Transplanting should be done after about six months when the plants reach a height of about 10 cm; the transplanted plant should be propagated in a loamy soil and kept moist.
Propagation by Cuttings
The following steps can be followed to propagate Bulliarda brevifolia using its cuttings:
- Select a healthy plant and cut a stem with a sharp and sterilized tool, ensuring that it is about 15 cm in length, with at least 4 nodes.
- Dip the cutting in a rooting hormone and plant it in a pot with well-draining soil, ensuring that it is kept moist but not waterlogged.
- Place the pot in a sheltered and shady position. The plant should be kept moist and not exposed to direct sunlight until the roots develop.
- After about six months, the cutting will have developed a strong root system and can be transplanted to its final position.
- Continue to care for the propagated plant as necessary.
Disease and Pest Management for Bulliarda brevifolia Eckl. & Zeyh.
Bulliarda brevifolia Eckl. & Zeyh., commonly known as the silver bulliarda or dwarf bulliarda, is a shrub native to southern Africa. It is known for its small silver-gray leaves, yellow flowers, and ability to grow in a variety of soil types.

It can be managed by removing and disposing of infected plant material and spraying the remaining plant with a fungicide. Another fungal disease that affects the silver bulliarda is black spot. This disease causes dark spots to appear on the leaves, eventually causing them to drop. Managing black spot involves removing infected plant material and spraying with a fungicide.
Common Pests
The silver bulliarda is also susceptible to certain pests, including spider mites and aphids. Spider mites are tiny pests that feed on the sap of the plant, causing leaves to yellow and drop. They can be managed by spraying the plant with an insecticidal soap or oil. Aphids are small insects that also feed on the sap of the plant. They can be managed by spraying the plant with a strong stream of water or by introducing natural predators, such as ladybugs.
