Light Requirements
Agathosma capitata Sond. prefers full sunlight. It cannot tolerate shady areas or partial shade. It is best grown in areas where it receives sunlight for most hours of the day. It requires a minimum of six hours of direct sunlight per day, which promotes optimal growth and flowering.
Temperature Requirements
The plant prefers warm temperatures ranging between 60 to 85 °F. It cannot tolerate frost or extremely hot temperatures. However, mature plants are tolerant of some light frost, but it will cause damage if the frost is severe. The plant grows best in a warm and sunny climate, and it will not survive in areas with long periods of cold weather.
Soil Requirements
The plant thrives in well-draining soils and sandy soils. The soil should have a pH level between 5.5 to 7.5. It grows best in soils that are deep, light, and slightly acidic. Agathosma capitata Sond. requires a soil that is enriched with organic matter and has good drainage. It does not perform well in compacted soils or soils that retain too much moisture. A suitable soil mix can be created by mixing sand or grit to the native soil to improve drainage and aeration.
Cultivation Methods
Agathosma capitata Sond., also known as Buchu, is a shrub native to South Africa. It prefers a well-drained soil that is slightly acidic and can withstand periods of drought. When it comes to propagation, this plant can be grown from both seeds and cuttings. For seeds, sow them in a well-draining soil mix and keep moist until germination. For cuttings, take semi-hardwood cuttings in late winter and root them in a mix of coarse sand and perlite.
Watering Needs
Agathosma capitata Sond. prefers a slightly dry soil and can tolerate short periods of drought. It is essential not to overwater this plant as it can lead to root rot. Water it once a week during the growing season but cut back on watering in the winter months. It is always best to check the soil moisture by sticking your finger into the soil before watering.
Fertilization
Buchu is not a heavy feeder and does not require a lot of fertilization. Use a balanced fertilizer during the growing season in the spring and summer to promote growth, and reduce to half strength in the fall. Avoid fertilizing in winter as the plant goes dormant.
Pruning
Buchu responds well to pruning and can be trimmed throughout the growing season. Prune lightly after flowering to encourage bushier growth and remove any dead or damaged branches. It is best to avoid heavy pruning as it can damage the plant and affect its growth in the following year.
Propagation of Agathosma capitata Sond.
There are different methods of propagating Agathosma capitata Sond., commonly known as the sand olive or kapokbossie. Below are some of the options:
Seeds propagation
One of the most common ways of propagating the sand olive plant is through seeds. This process involves harvesting the seeds directly from the plant when they are ripe. After collecting the seeds, they should be sown into a potting mix composed of sand and compost. The tray should be kept lightly moist, and seedlings should start to emerge between two and six weeks after sowing.
Cuttings propagation
Another method of propagation is through cuttings. This approach involves taking a section of the plant's stem or branch to grow a new plant. Choose a healthy stem and cut it at an angle, below a node. Remove any excess leaves from the cutting, leaving only two or three pairs at the top. Dip the cut end of the stem in rooting hormone, then insert the cutting into a well-draining potting mix. Keep the mix consistently moist but not oversaturated, and the cutting should start to root in a few weeks.
Division propagation
The plant also propagates through division, which involves separating an existing plant into two or more sections and planting them as new plants. This method works best at the beginning of the growing season when the plant is emerging from dormancy. Each division should have a portion of the root system and should be potted in a well-draining potting mix.
Whichever method of propagation is chosen, ensure that the resulting seedlings are transplanted into larger pots or outdoors once they have grown big enough to handle the transplanting process.
