Agathosma microcalyx Dummer is a plant species that is native to South Africa's Western Cape Province. The plant is commonly known by the names Buchu, Boegoe, and Round-leaf Buchu. Buchu is derived from the Khoikhoi language, which is an indigenous South African language. The plant has been used for medicinal purposes for centuries by the Khoisan communities in the region.
Appearance
Agathosma microcalyx Dummer is an evergreen shrub that typically grows up to two meters in height. The plant has rounded and fleshy leaves that are dark green in color. The leaves are glandular and exude an aromatic oil when crushed. The plant produces tiny white or pink flowers that bloom in late spring and early summer, and then bear small berries.
Uses
Buchu, the common name for Agathosma microcalyx Dummer, has been used for medicinal purposes for centuries by the Khoisan communities in South Africa. The leaves of the plant are rich in oil and have antiseptic, diuretic, and anti-inflammatory properties. Buchu is particularly effective in treating urinary tract infections, kidney infections, and bladder infections. It is also used to treat digestive issues such as flatulence, indigestion, and colic. Buchu oil is commonly used in perfumes and aromatherapy products due to its pleasant scent.
Aside from its medicinal uses, Agathosma microcalyx Dummer is also used in the manufacture of cosmetics and fragrances. It is particularly popular in the production of natural skin care products due to its cleansing and purifying properties.
Light Requirements:
Agathosma microcalyx prefers to grow in full sun or partial shade. It can tolerate direct sunlight for several hours a day, but it's best to protect it from the intense afternoon sun during hot summers.
Temperature Requirements:
This plant needs a warm and temperate climate to thrive. The ideal temperature range for Agathosma microcalyx is 55-77°F (13-25°C). It is sensitive to frost and is not suitable for growing in areas with extreme temperatures.
Soil Requirements:
Agathosma microcalyx prefers a well-draining, slightly acidic, and sandy soil. It can tolerate soil with a pH range of 5.5 to 7.5. The soil should be nutrient-rich and well-aerated to allow the plant's roots to develop and prevent the accumulation of water that can lead to root rot.
Water Requirements:
Agathosma microcalyx requires moderate watering during its growing season, which is from spring to autumn. The soil should be kept slightly moist but not waterlogged to avoid root rot. In winter, reduce watering to prevent the soil from becoming too wet, which can cause the plant to die.
Fertilizer Requirements:
Agathosma microcalyx does not require frequent fertilization. However, feeding it with a slow-release fertilizer once a year during spring can enhance growth and promote flowering. Avoid applying too much fertilizer as it can damage the plant.
Cultivation
Agathosma microcalyx Dummer, commonly known as buchu, is a shrub that is native to South Africa. It is a hardy plant that can grow up to 2 meters in height, and it prefers well-draining sandy soil. Buchu should be grown in full sunlight for optimal growth, and it is best suited for USDA hardiness zones 8 through 10.
Buchu can be propagated from seeds or cuttings. If growing from seeds, sow them in late autumn or early winter. The seeds should be placed in well-draining soil and kept moist until they germinate. Cuttings can be taken in the spring and rooted in a potting mix. Once the roots have established, the plant can be transplanted into the garden.
Watering
Buchu requires regular watering, especially during the growing season. The soil should be kept consistently moist but not waterlogged. Avoid overwatering, as this can lead to root rot. Watering can be reduced in the winter months when the plant is dormant.
Fertilization
Buchu does not require a lot of fertilizer, but a balanced, slow-release fertilizer can be applied in the spring to promote healthy growth. Avoid fertilizing in the winter months, as this can lead to new growth that is vulnerable to frost damage.
Pruning
Buchu benefits from regular pruning to maintain its shape and promote healthy growth. Pruning can be done in the spring before new growth appears. Remove any dead or damaged branches, as well as any crossing branches or branches that are growing inward. Avoid pruning in the winter months, as this can lead to frost damage.
Propagation of Agathosma microcalyx Dummer
Agathosma microcalyx Dummer, commonly known as Buchu, is a shrub-like plant that is native to South Africa. It grows up to 1-2 meters in height and produces small white or pink flowers in summer. Propagation of this plant can either be done through seeds or cuttings.
Propagation through seeds
The propagation of Agathosma microcalyx Dummer through seeds is relatively easy. The seeds need to be collected from the plant after the flowering season when they have fully matured. They can then be stored in a dry place until they are ready to be planted. Before planting, the seeds need to be scarified, which is the process of breaking the outer coating to enable water absorption. This can be done by soaking the seeds in warm water for a few hours. The seeds can then be planted in a well-draining soil mixture and kept moist. Germination can take up to two weeks.
Propagation through cuttings
Propagation of Agathosma microcalyx Dummer through cuttings is also a viable option. The best time to take cuttings is during the spring or summer months. Cuttings should be taken from healthy, mature plants and should be approximately 10-15 cm long. The bottom leaves should be removed, and the remaining leaves should be cut in half to reduce water loss. The cuttings can then be planted in a well-draining soil mixture and kept moist. Rooting hormone can be used to encourage root growth. The cuttings should be kept in a shaded area until they have developed roots, which can take up to six weeks.
Propagation of Agathosma microcalyx Dummer through seeds or cuttings is relatively easy, and with proper care and attention, the plant can thrive in various environments.
Disease and Pest Management for Agathosma microcalyx Dummer

Pests
Some pests that commonly attack Agathosma microcalyx Dummer include:
Spider Mites
Spider mites can suck the sap from the leaves of the Agathosma microcalyx Dummer, causing it to weaken and deform. To manage spider mites, keep the plant humidity high, prune affected leaves, and spray with insecticides that target spider mites.
Caterpillars
Caterpillars are another pest that can affect the Agathosma microcalyx Dummer, chewing the leaves and destroying the plant's aesthetic value. To manage caterpillars, handpick and destroy them or use insecticides that target caterpillars.
Mealybugs
Mealybugs are another pest that can infest the Agathosma microcalyx Dummer, feeding on the sap and reducing the plant's vigor. To manage mealybugs, prune affected leaves, use insecticides that target mealybugs, or use natural predators like ladybugs.
Diseases
Some diseases that commonly affect Agathosma microcalyx Dummer include:
Stem Rot
Stem rot is a fungal disease that can affect the Agathosma microcalyx Dummer, causing the stems to rot and making the plant susceptible to other infections. To manage stem rot, improve drainage, do not overwater, avoid overcrowding the plant, and prune affected parts.
Leaf Spot
Leaf spot is a fungal disease that can cause spots to form on the leaves, reducing the plant's aesthetic value. To manage leaf spot, prune affected leaves, avoid overcrowding, and use fungicides that target leaf spot.
Root Rot
Root rot is a fungal disease that can attack the root system, causing the plant to wilt and die. To manage root rot, improve drainage, avoid overwatering, use sterile soil, and apply fungicides that target root rot.
