As with any plant, it is important to ensure that Notonia coccinea Oliv. & Hiern. is not invasive in your area and that any environmental regulations are being followed if you plan to grow it.
Light Conditions
Notonia coccinea Oliv. & Hiern requires bright and indirect sunlight, making it a perfect plant that can be placed in a spot with a lot of natural light. It can also thrive in filtered or partial sunlight. Direct sunlight can scorch the leaves and cause discoloration, so it is vital to avoid placing it in direct sunlight.
Temperature Conditions
The ideal temperature range for the growth of Notonia coccinea Oliv. & Hiern is between 18°C to 27°C. The plant can still survive in temperatures ranging from 12°C to 32°C if it is not prolonged. It can also tolerate a range of humidity, making it an adaptable addition to the home or office environment.
Soil Conditions
Notonia coccinea Oliv. & Hiern prefers well-draining soil. The soil must not be compacted and must contain organic matter. A good mix of potting soil and peat moss or vermiculite can provide the best growth conditions for the plant. The soil pH must be neutral or slightly acidic, ranging between 6.0–7.0. Overwatering can cause root rot, so the soil's drainage must be checked now and then.
Cultivation
Notonia coccinea, also known as the scarlet cushion, is a South African succulent that thrives in warm, arid climates. When planting this species, choose a well-draining soil mix that is low in organic matter and high in sand. Ensure the pot has adequate drainage holes and is placed in an area that receives plenty of bright, indirect sunlight for optimal growth.
Plant Notonia coccinea by gently placing the plant into the soil and adding extra soil mix around it. Keep the plant at a shallow depth, and avoid burying its stem. If planting outdoors, it is best to do so in the early spring or summer months when the soil is warm and the temperature is ideal for the plant to establish its roots.
Watering
Notonia coccinea requires infrequent watering, as it is adapted to drought conditions. Overwatering can cause root rot and other fungal diseases, so it is important only to water the plant once the soil has become completely dry. During the warmer months, watering once every two to three weeks is sufficient. In the winter, reduce watering to once every four to six weeks.
When watering, it is recommended to use room temperature water and to ensure that the entire soil surface is moistened. This can be achieved by pouring the water into the soil until it starts to drain from the pot's drainage holes.
Fertilization
Notonia coccinea does not require much fertilization, but a slow-release cactus fertilizer can be applied once a year during the growing season. To avoid over-fertilization, it is essential to follow the manufacturer's instructions carefully. It is also possible to supply the plant with the necessary nutrients by adding compost to the soil mix before planting.
Pruning
Notonia coccinea does not require pruning in the traditional sense, as it grows into a naturally rounded shape. However, it is essential to remove any dead or damaged leaves or stems to maintain the plant's appearance and health. Additionally, it is important to remove the plant's flowers once they have wilted to prevent the development of seeds and to extend the plant's blooming period.
Propagation of Notonia coccinea Oliv. & Hiern
Notonia coccinea Oliv. & Hiern, also known as the African Foxglove, is a popular ornamental plant due to its unique and attractive red flowers. The plant can be propagated through various methods, including seed propagation, stem cutting, and division.
Seed Propagation
Seed propagation is a common method used to propagate Notonia coccinea. The seeds should be sown in a well-draining potting mix. The seeds usually take 2-4 weeks to germinate, and the ideal temperature for germination is around 20-25°C. Once germinated, the seedlings can be transplanted into individual pots.
Stem Cutting Propagation
Notonia coccinea can also be propagated through stem cutting. Take a cutting of around 10cm in length from a healthy stem of the plant. Remove the bottom leaves and dip the cutting in rooting hormone powder. Plant the cutting in a well-draining potting mix and water it regularly. The cutting should start to form roots within 2-4 weeks.
Division Propagation
Notonia coccinea can be propagated through division during the early spring months. Carefully remove the plant from its pot and gently separate the clumps into smaller sections, making sure each section has some roots attached. Re-pot each section in a well-draining potting mix and water it regularly. The new plants should start to grow within a few weeks.
By using one of these methods, you can easily propagate Notonia coccinea and continue to enjoy this lovely ornamental plant in your garden or indoor space.

Common Diseases
Powdery Mildew: This is a common fungal disease that affects the leaves, stems and flowers of the plant. It appears as a white or grey powdery substance on the surface of the infected plant parts. To manage this disease, remove any infected parts of the plant and apply a fungicide according to the manufacturer's instructions. Avoid overhead watering and ensure proper air circulation around the plant.
Root Rot: This disease is caused by a fungal infection that affects the roots of the plant, making it wilt and turn yellow. To manage this disease, remove infected plants and ensure good drainage in the soil. Avoid over-watering and fertilizing. It is also advisable to use a fungicide to prevent the disease from spreading to other plants.
Common Pests
Aphids: These tiny insects feed on the sap of the plant, causing the leaves to curl and turn yellow. To manage this pest, use natural predators like ladybugs or lacewings, or spray the plant with insecticidal soap or neem oil.
Thrips: These are common pests that can cause the leaves of Notonia coccinea to become discolored and distorted. They can also transmit viruses to the plant. To manage this pest, remove and destroy any infected parts of the plant. You can also use sticky traps or insecticidal soap to control their population.
Spider Mites: These pests are tiny and difficult to see. They feed on the plant's sap, causing the leaves to become stippled and eventually dry out and die. To manage this pest, use natural predators like predatory mites or ladybugs, or spray the plant with insecticidal soap or neem oil.
In conclusion, managing diseases and pests in Notonia coccinea requires a keen eye for detail, frequent checking and ensuring proper plant care practices. Regular monitoring can help identify problems early and manage them before they get out of hand.
