Origin and Distribution
Pavonia rotundifolia is native to Africa and can be found in the countries of Sudan, South Sudan, Ethiopia, Tanzania, and Kenya. It thrives in areas with high humidity and requires well-drained soil to flourish. The Round-leaved Pavonia can grow in open grasslands, disturbed areas, and forest edges.
Common Uses
Pavonia rotundifolia has a few practical uses. The root of this plant is used in traditional medicine to treat various ailments such as fever, colds, and respiratory infections. The leaves are also used to make tea, which is believed to have healing properties. Additionally, the Round-leaved Pavonia is an ornamental plant and is sometimes grown as an indoor plant due to its small size and attractive appearance.
Light Requirements
Pavonia rotundifolia typically grows in areas with partial shade. It prefers to receive around 4-6 hours of sunlight, but too much direct sunlight can harm the plant. Exposure to too much sunlight can lead to wilting or yellowing of the leaves.
Temperature Requirements
Pavonia rotundifolia requires warm temperatures to grow. It thrives in an environment where the temperature ranges from 60-80°F (15.5-26.6°C). It cannot tolerate frost and needs to be protected in colder temperatures.
Soil Requirements
The soil for Pavonia rotundifolia needs to be well-draining and fertile. It grows best in soil that is rich in organic matter and has a pH level between 6 to 7.5. The soil should not be too dry or too moist. One way to ensure a well-balanced soil is to mix in sand or peat moss to promote good drainage.
Cultivation
Pavonia rotundifolia is a great houseplant for beginners. Being a semi-succulent, it is more forgiving than traditional plants. It is a low-maintenance plant that thrives in bright, indirect light. However, direct sunlight should be avoided as it can scorch the leaves.
The plant prefers to grow in well-draining soil with a neutral pH. With a pH of 6.0 to 7.5, it can grow in soil that is slightly acidic to slightly alkaline. It can also tolerate brief periods of drought as it stores water in its leaves. However, it is best to keep the soil moist to promote growth.
Watering Needs
Watering pavonia rotundifolia is relatively easy. In the growing season, the plant needs to be watered thoroughly at least once a week. The soil should be allowed to dry slightly between the waterings.
During winter, watering should be reduced to once every two or three weeks. This ensures that the plant doesn't become waterlogged, which can lead to root rot.
Fertilization
Pavonia rotundifolia is not a heavy feeder, and therefore, does not require frequent fertilization. Fertilizing once every three months during the growing season using a balanced liquid fertilizer will suffice. However, it should not be fertilized during winter as the plant enters a dormant stage.
Pruning
The plant does not require extensive pruning. However, it is advisable to trim back any yellow or dead leaves to prevent the spread of disease. Trimming also encourages new growth. The best time to prune pavonia rotundifolia is during the growing season. Overgrown or leggy plants can also be trimmed back to promote compact growth.
Propagation of Pavonia rotundifolia Thulin & Vollesen
Pavonia rotundifolia Thulin & Vollesen is a perennial with excellent growth potential. It can be propagated in various ways to increase the plant population. Here are the different methods of propagation that can be employed:
Seeds
The propagation of Pavonia rotundifolia can be through seeds. To obtain the seeds, the flower of the plant is allowed to mature, and the seed pods are harvested. Once the pods are harvested, they should be dried, and the seeds removed for sowing. The seeds should be sown in a well-draining soil mix, covered lightly with soil and watered sparingly to keep the soil moist. Germination typically begins within two weeks, and the plants can be transplanted to individual containers once they have developed two to four leaves.
Stem cuttings
Pavonia rotundifolia can also be propagated through stem cuttings. The parent plant should be pruned, and the cuttings should be taken from the tips of the stems, ensuring that each cutting has at least two to four leaves. The cutting should then be dipped into rooting hormone and planted into a well-draining soil mix. The stem cuttings should be watered lightly to prevent the soil from drying out and kept in a warm, humid environment. Once the roots have developed and new growth appears, the newly propagated plant should be set in an individual pot.
Division
Another way to propagate Pavonia rotundifolia is through plant division. The parent plant should be lifted out of the soil and divided into several clumps. Each clump should have several stems and roots attached to it. The divided plants should then be planted in an individual container with fresh soil and kept moist. Within a few weeks, new growth should start to appear, and the plant will have successfully propagated.
Disease and Pest Management for Pavonia rotundifolia Thulin & Vollesen
Pavonia rotundifolia Thulin & Vollesen, commonly known as buttonbush mallow or roundleaf pavonia, is a beautiful flowering plant that belongs to the Malvaceae family.

To keep your Pavonia rotundifolia healthy and thriving, you must take appropriate measures to manage the diseases and pests that may infect it. Here are some common diseases and pests that affect Pavonia rotundifolia and ways to manage them:
Diseases
1. Powdery Mildew: Powdery mildew is a fungal disease that causes a white powdery coating on the leaves, stems, and flowers of the plant. It can weaken the plant and affect its overall health. To manage powdery mildew in Pavonia rotundifolia, you must spray a fungicide containing potassium bicarbonate or neem oil. Ensure that you water the plant from below and avoid getting water on the leaves, as this can promote the growth of the fungus.
2. Leaf Spot: Leaf spot is a fungal disease that causes brown or black spots on the leaves of the plant. It can be caused by overwatering, poor air circulation, or high humidity. To manage leaf spot in Pavonia rotundifolia, you must prune the infected leaves and spray a fungicide containing copper sulfate or chlorothalonil.
Pests
1. Aphids: Aphids are small insects that suck the sap from the plant, causing stunted growth and curling of the leaves. To manage aphids in Pavonia rotundifolia, you can wash them off with a strong jet of water or spray insecticidal soap. You can also introduce natural predators, like ladybugs or lacewings, to control the aphid population.
2. Spider Mites: Spider mites are tiny pests that feed on the plant, causing yellowing and wilting of the leaves. To manage spider mites in Pavonia rotundifolia, you must regularly spray the plant with water to increase moisture levels and encourage natural predators, like predatory mites or thrips. You can also spray the plant with insecticidal soap or neem oil.
By taking appropriate measures to manage diseases and pests that affect Pavonia rotundifolia, you can ensure that your plant remains healthy and thrives.
