During the winter months, it is best to keep the plant indoors in a warm location with sufficient sunlight. Cold temperatures can cause irreparable damage to the plant.
Soil Requirements
Pavonia insignis Fenzl ex Webb requires well-draining soil with a pH ranging from 6.5 to 7.5. The soil must be rich in organic matter, and should ideally contain a mix of peat moss, perlite, and sand. The plant is sensitive to soggy soil, which can cause root rot and lead to the death of the plant. The addition of sand or perlite to the soil mix will help to improve drainage and prevent waterlogging.
Cultivation
Pavonia insignis Fenzl ex Webb, or Velvetleaf Pavonia, is a plant that can be grown outdoors in USDA plant hardiness zones 9b through 11. It thrives in full sun or partial shade and prefers well-draining, sandy loam soil that is rich in organic matter. This plant can be propagated through seed or cuttings, and it typically blooms in the summer and fall.
Watering needs
Velvetleaf Pavonia is a plant that has moderate water needs. It should be watered deeply but infrequently, allowing the top layer of soil to dry out before watering again. Overwatering can lead to root rot, so be sure to check the soil's moisture level before watering. In general, this plant needs more water during the hot summer months and less water in the winter.
Fertilization
Velvetleaf Pavonia is a plant that benefits from regular fertilization. It requires a balanced, slow-release fertilizer that contains equal parts of nitrogen, phosphorous, and potassium. Fertilize the plant every four to six weeks during the growing season, following the manufacturer's instructions for application rates and timing.
Pruning
Pruning Velvetleaf Pavonia can help keep the plant tidy and promote healthy growth. It should be pruned in the late winter or early spring before the plant begins to produce new growth. Prune any dead or diseased branches and remove any crossed branches to promote better air circulation. You can also pinch back the tips of the stems to promote bushier growth.
Propagation of Pavonia Insignis Fenzl ex Webb

Propagation Methods
The propagation of Pavonia insignis can be done either through seeds or cuttings.
Seed Propagation
The seeds of Pavonia insignis usually germinate within 2-4 weeks. The seeds should be sown in a soil mixture of 1:1 sand and peat moss. Keep the soil moist and at a constant temperature of around 70°F to encourage germination. Once the seedlings have grown enough, transplant them into individual pots. It takes about 4-6 months for the seedlings to establish themselves and start flowering.
Cutting Propagation
Cuttings can be taken in the spring or early summer when the plant is actively growing. Take cuttings of about 4-6 inches in length, ensuring that they have at least 2-3 leaf nodes. Dip the cuttings in rooting hormone powder and plant them in a pot containing a moist, loamy soil mix. Keep the cuttings in a warm, humid environment, and mist them regularly. New shoots should start appearing within a few weeks. Once the cuttings have rooted, transplant them into individual pots and continue to care for them until they are ready to be planted in your garden or landscape.
