Cultivation Methods
Agathosma phillipsii Dummer is a shrub that is native to South Africa and requires a Mediterranean-like climate to thrive. It is a hardy plant that grows in well-drained soils and full sun. When planting, ensure there is enough space for the shrub to grow to its full size, with a minimum of 3 feet between each plant. The ideal time to plant is in the springtime. It is essential to plant this shrub in a location that is protected from strong winds.
Watering Needs
Agathosma phillipsii Dummer requires moderate watering. Water the plant regularly, ensuring that the soil is moist but not wet. Overwatering can lead to root rot and ultimately kill the shrub. Reduce the watering frequency when the plant is dormant in the winter months.
Fertilization
Agathosma phillipsii Dummer benefits from a regular dose of fertilizer. Apply a balanced, slow-release fertilizer during the growing season. Ensure that the fertilizer is evenly distributed around the shrub, keeping it away from the roots. Avoid fertilizing during the winter season when the plant is dormant.
Pruning
Pruning Agathosma phillipsii Dummer is critical in ensuring that it maintains its shape and size. Prune the shrub once every year during its dormant season, which is in the winter months. Remove the dead, diseased, or damaged wood, and cut back older stems to just above the point where new growth begins. Additionally, prune all the stems that are not growing in the right direction to encourage inward growth and denser foliage.
Propagation of Agathosma phillipsii Dummer
Agathosma phillipsii Dummer can be propagated through seeds and cuttings. Both methods have their advantages and disadvantages.
Propagation through Seeds
Seeds are usually sown in autumn or spring. Harvested seeds need to be cleaned and stored in a cool, dry place until sowing time. Seeds can be sown in trays or directly in pots. It is recommended to use a mix of sand, perlite, and peat moss as the growing medium. The seeds need to be placed on the surface of the growing medium and not buried. Water the soil moderately, and use plastic or glass to cover the pot or tray to maintain humidity. Germination usually takes two to three weeks, and the seedlings need to be transplanted once they have true leaves.
Propagation through Cuttings
Cuttings are usually taken in late spring or early summer. The cuttings are taken from semi-hardwood stems, which are neither too soft nor too woody. The cuttings should be around 5 to 7cm in length. Remove the leaves from the bottom part of the cutting and dip it in rooting hormone. The cutting should then be placed in a mix of sand and peat moss and kept in a humid environment until roots appear, which usually takes around four to six weeks. Once the roots have formed, the cutting can be transplanted into individual pots.
