Pruning Aspalathus arida E.Mey. subsp. arida
Aspalathus arida E. Mey. subsp. arida requires minimal pruning. However, to maintain the plant's shape and encourage bushier growth, you can prune the tips of the branches after flowering. Dead, damaged or diseased branches should be removed promptly to prevent the spread of disease. Avoid pruning during the winter months as the plant's growth is slow at this time.
Propagation of Aspalathus arida E.Mey. subsp. arida
Aspalathus arida E.Mey. subsp. arida, commonly known as Cape Mountain Tea, is propagated through both seeds and vegetative means. The method of propagation depends on the purpose, efficiency, and the availability of resources.
Propagation through Seeds
Propagation through seeds is the most common method for Aspalathus arida E.Mey. subsp. arida. The seeds are usually collected in late summer or early autumn when they are mature and dry. These seeds must be scarified or soaked in hot water for 24 hours to soften the hard seed coat and promote germination. The pretreated seeds must then be sown in well-draining, sandy soil, and covered with organic material to maintain moisture.
Seed propagation is beneficial for producing large quantities of plants at a lower cost than vegetative propagation. However, seedlings may have variable characteristics, making them a less reliable means of guaranteeing traits such as a specific flavor profile or growth habit.
Propagation through Vegetative Means
Aspalathus arida E.Mey. subsp. arida can also be propagated through vegetative means, including cuttings, layering, and grafting. Vegetative propagation is advantageous as it helps maintain desirable traits that can be lost through sexual reproduction.
Cuttings are taken from mature stems during the growing season, and ideally, cuttings should be 5-7 cm long. They can be dipped in rooting hormone and placed in perlite or a well-draining soil mixture. After rooting, these cuttings can be transplanted to their final location.
Layering involves burying a portion of the stem underground, where new roots can develop. The rooted layer can then be detached from the parent plant and transplanted separately.
Grafting involves attaching a stem cutting from the desired plant onto a rootstock of a different Aspalathus species. Grafting is generally not recommended for Aspalathus arida E.Mey. subsp. arida as it does not thrive well when grafted onto other rootstocks.
Overall, both seed and vegetative propagation methods can be used to propagate Aspalathus arida E.Mey. subsp. arida and can provide the grower with an abundance of plants to contribute towards the tea industry.
