Cultivation Methods
Senecio scaposus DC. var. addoensis (Compton) G.D.Rowley is a succulent plant, native to South Africa. It needs to be grown in well-draining soil that allows good ventilation. The plant can be propagated through stem cuttings or by seeds.
To propagate through cuttings, allow fresh cuttings - about 10cm long - to form a callus for a few days before planting them in well-draining soil. It is good to keep the soil slightly moist until roots form, which usually takes about two or three weeks.
Regarding seeds, it is recommended to sow them in spring or early summer in a well-draining soil mix. Keep in a warm, bright area, with good moisture and ventilation. Germination usually occurs within two to three weeks.
Watering Needs
Senecio scaposus DC. var. addoensis is a drought-resistant plant and can withstand periods of water scarcity. However, do not neglect watering entirely. During summer, water the plants thoroughly every two weeks. During winter, reduce watering to once a month. Ensure that the soil has drained appropriately before applying further watering.
Fertilization
Fertilizing succulents should be done infrequently. Use a balanced, water-soluble fertilizer at half the recommended strength during the active growing months, usually between spring and summer. Fertilizers containing a higher percentage of potassium and phosphorus are recommended. However, be sure to avoid over-fertilization since it can harm Senecio scaposus DC. var. addoensis, leading to weak growth and susceptibility to pests and diseases.
Pruning
Senecio scaposus DC. var. addoensis is a slow-growing plant that typically does not require frequent pruning. However, if the plant becomes leggy or stretched because of low light conditions, pruning can be done to promote a more compact and bushy growth habit.
