Cultivation methods:
Jacobaeastrum asparagoides (Licht. ex Less.) Kuntze, commonly known as Cape ivy, is a vine species that is native to South Africa. It is a prolific grower and can quickly cover large areas. When cultivating Cape ivy, it's essential to ensure that it doesn't invade nearby vegetation, so you want to grow it in a container or a designated bed. It prefers full sun to partial shade and fertile, well-draining soil. The plant also grows best in warmer temperatures and can tolerate some drought conditions.
Watering needs:
Cape ivy requires regular watering to thrive. Water the plant deeply at least once a week during the growing season and more frequently during hot and dry weather conditions. Ensure that the soil is well-draining to prevent standing water around the plant's roots, which can cause root rot.
Fertilization:
When growing Cape ivy, adding a balanced, slow-release fertilizer once a year in the spring can help the plant grow faster and healthier. Ensure that the fertilizer doesn't touch the plant's leaves or stems as it can cause discolouration or burn them.
Pruning:
To promote healthy growth, Cape ivy requires regular pruning. Train the vines to the desired shape while it's young and remove excess growth as needed during the growing season. Cut back the plant's growth in late winter or early spring before new growth emerges, allowing the plant to maintain its shape and avoid becoming too leggy.
