Light Requirements
Struthiola dodecandra requires full sun in order to grow successfully. It is a plant that is well-adapted to hot and dry climates, and therefore needs plenty of direct sunlight to thrive.
Temperature Requirements
This plant can tolerate a wide range of temperatures, ranging from 5°C to 40°C. However, it is best suited to warm/hot climates, with temperatures between 25°C and 35°C being ideal. It is important that temperatures do not drop below 0°C, as this may damage the plant.
Soil Requirements
Struthiola dodecandra prefers well-drained soils that are sandy or gritty. It can tolerate slightly acidic to alkaline soils, with a pH range of 6 to 8.5. It is important that the soil does not become waterlogged, as this can lead to root rot and other issues.
Cultivation Methods
Struthiola dodecandra, also known as Cape Gold or Golden Pagoda, is a plant endemic to South Africa. It is a small, evergreen shrub that can grow up to 60 cm in height and spread up to 70 cm wide. It is tolerant of poor soil, drought, and salt spray, making it a great choice for coastal gardens.
The plant can be propagated from seeds or cuttings. When propagating from seeds, scarify them lightly and soak them in water for a few hours before sowing them in well-draining soil. The seeds should germinate in two to four weeks. When propagating from cuttings, use a sharp, clean blade and take cuttings that are 5-10 cm long, removing any leaves from the bottom. Dip the cuttings in rooting hormone and plant them in soil mixed with sand or perlite. Keep the soil moist until the cuttings root, which could take several weeks.
Watering Needs
Struthiola dodecandra is drought-tolerant and does not need to be watered frequently. However, it is essential to keep the soil moist when the plant is young until it establishes its roots and also during the hot and dry summer months. Water the plant deeply at the base, avoiding wetting the foliage, which can lead to fungal diseases and pests.
Fertilization
Struthiola dodecandra does not require heavy feeding and can survive without fertilization. However, applying a balanced slow-release fertilizer once a year at the beginning of the growing season can improve the plant's growth and flowering. Avoid applying excess nitrogen-rich fertilizers as it can lead to excessive foliage growth at the expense of flowering.
Pruning
Pruning Struthiola dodecandra is not necessary, but it can improve the plant's shape and flowering. Prune any dead or damaged branches, and cut back any excessively long branches to encourage bushiness. It is best to prune the plant in late winter or early spring before new growth appears.
Propagation of Struthiola dodecandra
Struthiola dodecandra (L.) Druce, commonly known as the African twelve apostles, is commonly propagated through seed germination. Planting seeds is the most common method of propagating this plant. The seedlings typically appear within two weeks of planting and should be transplanted to their permanent location after six months.
When collecting seeds, it is necessary to collect them from healthy plants. Collecting in the morning, when the seeds are dry and have not yet been scattered, is the best time. Collect the seedpods once they have turned brown and have started to crack open. Remove the seeds from the pod and store them in a cool and dry place.
Before planting, soak the seeds overnight in water to soften the seed coat. Plant the seeds in well-draining soil mix, one inch deep into the soil. Keep the soil moist, but not overly wet, and ensure that the planting area is in a sunny location.
Propagation of Struthiola dodecandra is relatively easy and is not commonly done through vegetative propagation. Seed germination is a simple way to increase or maintain the population of this plant.
Disease Management
Struthiola dodecandra may be susceptible to various diseases that may affect its growth and productivity. Common diseases that affect this plant include root rot, leaf spot, and powdery mildew.
Root rot is usually caused by overwatering and poor soil drainage. To manage this disease, ensure that the soil is well-draining and avoid overwatering the plant. Additionally, you can treat the plant with a fungicide such as neem oil or copper sulfate.
Leaf spot is characterized by yellow or brown spots on the leaves of the plant. To manage this disease, remove the affected leaves and treat the plant with a fungicide such as neem oil or copper sulfate.
Powdery mildew appears as a white powdery coating on the leaves of the plant. To manage this disease, remove the infected leaves and treat the plant with a fungicide such as sulfur or neem oil.
Pest Management
Struthiola dodecandra may also be vulnerable to various pests that may affect its growth and productivity. Common pests that affect this plant include spider mites, thrips, and aphids.
Spider mites are tiny pests that are difficult to see without magnification. To manage these pests, spray the plant with a mixture of water and soap, or use an insecticidal soap or neem oil.
Thrips are tiny insects that pierce and suck the sap from leaves, causing discoloration and deformation. To manage them, remove infested leaves and spray the plant with neem oil or insecticidal soap.
Aphids are tiny insects that suck the sap from the plant's leaves, causing them to curl and yellow. To manage these pests, treat the plant with a mixture of water, soap, and neem oil or use an insecticidal soap.
