Arctotis revoluta DC. thrives in full sunlight. Thus, it is best to provide the plant with at least six to eight hours of direct sunlight per day. A location that receives plenty of morning sunlight is ideal. However, they can also grow in partial shade, but they may produce fewer flowers.
Temperature Requirements
The plant can tolerate a wide range of temperatures. However, they prefer mild temperatures that range from 60 to 75 degrees Fahrenheit. It is crucial to keep the plant indoors during winter to avoid exposing them to freezing temperatures. Additionally, temperatures above 85 degrees Fahrenheit can lead to heat stress and restrict growth in the plant.
Soil Requirements
The Arctotis revoluta DC. plant prefers well-draining soil that is porous to support optimal health. A pH level of 6.0-7.0 will enhance nutrient availability. Therefore, you can use loamy soils that offer a good balance of sand, silt, and clay. You can add organic matter like peat moss, manure, or compost to your soil to increase the nutrient content. Avoid planting this plant in heavy, waterlogged soils that retain water and make it difficult for the plants to grow.
Cultivation Methods
Arctotis revoluta DC. is a beautiful perennial plant that grows up to 30 centimeters in height. It is native to South Africa and is well adapted to growing in Mediterranean-like climates. The plant requires a well-draining soil with a pH of around 6.0-7.0 and a sunny spot that receives at least 6 hours of direct sunlight every day. It is essential to plant them in a location protected from strong winds to ensure they do not break from bending.
Watering Needs
Arctotis revoluta DC. does not like to be overwatered. Frequent watering can lead to root rot. It is best to water the plant moderately but regularly. During the hot summer months, the plant will need more water, and so it is advisable to increase watering frequency to once every two days. During winter, the soil can be allowed to dry out a bit more before watering.
Fertilization
Use a slow-release fertilizer with a balanced N-P-K ratio of 10-10-10 for best results. Apply the fertilizer once every three months during the growing season, which is spring and summer. Do not fertilize during the winter months as the plant is dormant.
Pruning
Arctotis revoluta DC. does not require frequent pruning. However, it is advisable to deadhead the flowers regularly to encourage further blooming. Pinch off spent flowers just above the first set of leaves using a pair of garden scissors. If the plant has become too leggy or overgrown, it can be pruned back by up to one-third of its height just after blooming has ended in summer.
Propagation of Arctotis revoluta DC.
Arctotis revoluta DC. can be propagated through a variety of methods, including seed propagation, stem cuttings, and division.
Seed propagation
The easiest and most commonly used method for propagating Arctotis revoluta DC. is through seed propagation. The seeds can be sown directly or started indoors and then transplanted. The ideal time for sowing seeds is during the spring or summer months. The seeds should be sown in a well-draining soil mix, kept moist, and provided with bright, indirect light. The seeds will typically germinate within 2-4 weeks.
Stem cuttings
Stem cuttings are another effective method of propagating Arctotis revoluta DC. Cuttings should be taken from new growth at the beginning of the growing season. The cuttings need to be about 6 inches long with at least two sets of leaves. Remove the lower leaves from the stem leaving only the top two sets. The cuttings should be dipped in rooting hormone and then planted in a well-draining soil mix. Keep the soil moist but not waterlogged and provide bright, indirect light. The cuttings should begin to root within 2-3 weeks.
Division
Arctotis revoluta DC. can also be propagated through division. This method involves separating the plant into smaller sections and replanting them individually. The best time to divide the plant is at the beginning of the growing season. Dig up the plant and carefully separate the root ball into smaller sections, making sure each section has a sufficient amount of roots attached. Replant the sections in a well-draining soil mix and keep the soil moist. Provide bright, indirect light and avoid direct sunlight until the plants are established.
Regardless of the chosen propagation method, Arctotis revoluta DC. prefers a well-draining soil mix, bright, indirect light, and consistent moisture. After successful propagation, the new plants can be transplanted into their permanent location while taking care not to damage the roots.
Disease and Pest Management for Arctotis revoluta DC.

To manage powdery mildew, spray the affected parts of the plant with a fungicide containing sulfur or neem oil. Ensure that the plant is well-ventilated and receives adequate sunlight.
Botrytis Blight
Botrytis blight is a fungal disease that causes brown spots on the leaves and flowers. It can cause the plant to wilt and die if left untreated. To manage botrytis blight, remove all affected plant parts and discard them. Ensure that the plant is well-ventilated and receives adequate sunlight. Apply a fungicide containing sulfur or copper oxychloride to prevent further infections.
Pests
Arctotis revoluta DC. is prone to several pests, including:
Aphids
Aphids are small, soft-bodied insects that suck the sap from the plant, causing stunted growth and curling of leaves. To manage aphids, wash the plant with a strong spray of water to dislodge the insects. Alternatively, apply insecticidal soap or neem oil to the plant to kill the aphids.
Spider Mites
Spider mites are tiny, sap-sucking pests that can cause yellowing and mottling of leaves. They can also produce fine webbing around the plant. To manage spider mites, spray the plant with water to dislodge the pests. Alternatively, apply insecticidal soap or neem oil to the plant to kill the mites.
Thrips
Thrips are small, winged insects that suck the sap from the plant, causing leaves to curl and turn brown. To manage thrips, apply insecticidal soap or neem oil to the plant to kill the pests. Ensure that the plant is moisture-free, well-ventilated, and receives adequate sunlight.
By being vigilant and regularly inspecting the plant for signs of disease and pests, you can prevent significant damage and keep your Arctotis revoluta DC. healthy and beautiful.
