Light Requirements
Diosma haelkraalensis requires a substantial amount of light to survive and thrive. These plants have been observed growing in partial shade, but it is recommended to keep them in a location that receives full sunlight exposure for at least six hours a day. Insufficient light can cause elongation of stems and a decrease in the production of flowers.

Diosma haelkraalensis grows well in moderate temperatures that range between 10°C to 25°C. The optimum temperature for the growth of this plant is 18°C to 24°C. Additionally, they are tolerant to temperature fluctuations but cannot sustain extreme heat or frosty conditions. Therefore, it is crucial to keep the plant in a warm location and away from frosty areas to prevent damaging the foliage and flower production.
Soil Requirements
The soil condition plays a significant role in determining the growth and development of Diosma haelkraalensis. The plant prefers well-draining and acidic soil with a pH ranging between 5.5 to 6.5. The soil should be rich in humus and organic matter and have excellent drainage to prevent waterlogging, which harms the plant's roots. If the soil is clayey or heavy, improve it by adding sand, perlite, or vermiculite to enhance aeration and drainage.
Cultivation
Diosma haelkraalensis I.Williams, commonly known as Haelkraal Buchu, is a small, evergreen shrub that grows well in warm, arid, and Mediterranean climates. It requires full sun exposure and well-draining soil for proper growth and development. The plant is susceptible to frost damages; hence, it's advisable to grow it indoors in regions with freezing winters.
Watering Needs
As with most shrubs, Diosma haelkraalensis I.Williams grows well in well-drained soils and requires watering only once a week or when the soil surface is dry to the touch. It's crucial to avoid overwatering as it can cause root rot and, in severe cases, death of the plant. During hot seasons or periods of drought, the plant may require more frequent watering to keep the soil moist.
Fertilization
Fertilization is an essential aspect of Diosma haelkraalensis I.Williams cultivation and care. The plant requires fertilization once every two weeks during the growing season, which usually occurs in late spring and early summer. Apply a balanced fertilizer, such as a 10-10-10 blend, at half the recommended dose. Overfertilization can lead to burnt or damaged foliage.
Pruning
Regular pruning of Diosma haelkraalensis I.Williams is essential for maintaining a compact shape and encouraging healthy growth. Pruning should be done in late winter or early spring after the last frost. Cut back any dead or damaged branches and trim the remaining foliage to maintain a desirable shape. Avoid pruning more than a third of the plant's total size during any given pruning session.
Propagation of Diosma haelkraalensis I.Williams
Diosma haelkraalensis I.Williams, commonly called Haelkraal Buchu, is a type of shrub native to the Western Cape of South Africa. Propagation of Diosma haelkraalensis is possible through several methods.

Diosma haelkraalensis can also be propagated through softwood cuttings. Choose healthy softwood cuttings with no flowers or buds and around six inches long. Dip the end of the cutting in rooting hormone and plant it in a pot with well-draining, moist soil. Cover the pot with a plastic bag to create a humid environment. Place the pot in a well-lit area but not in direct sunlight. In a few weeks, the roots will develop, and the plant can be transplanted to a larger pot or permanent location.
Layering propagation
Layering propagation is another technique to propagate Diosma haelkraalensis. Choose a healthy branch and bend it towards the soil. Make sure the branch makes contact with the soil. Cover the branch with soil and secure it in place with a wire or stone. Keep the soil moist and wait for a few months for the roots to develop. After that, cut the branch off the main plant and transplant it to a permanent location.
Conclusion
Overall, Diosma haelkraalensis is an easy-to-propagate plant. The best time to propagate it is in spring or summer when the plant is actively growing. Choose the propagation method that suits your needs and experience level the best, and you will soon have more Haelkraal Buchus to enjoy.
