Light Requirements
Abutilon auritum thrives in full sun to partial shade conditions. The plant can tolerate low light, but it blooms best in bright sunlight. Insufficient light can lead to slower growth and poor blooming patterns.
Temperature Requirements
The optimal temperature range for Abutilon auritum growth is between 18-27 degrees Celsius. The plant can tolerate temperatures as low as 5 degrees Celsius but may suffer leaf damage when exposed to freezing temperatures. High-temperature fluctuations can also stress the plant and negatively impact its growth.
Soil Requirements
Abutilon auritum prefers well-draining soil with a slightly acidic to neutral pH range of 5.5-7.5. The soil should be rich in organic matter and have good water-holding capacity. The plant can tolerate dry soil conditions but does best when soil moisture is consistent. Heavy clay soils can impede root growth and make the plant more susceptible to root rot.
It is recommended to amend the soil with compost or well-rotted manure before planting to improve soil structure and fertility. Adding a layer of mulch around the plant can help maintain soil moisture levels and prevent weed growth.
Cultivation methods
Abutilon auritum, also known as golden flowered mallow, is a shrub native to the Himalayan region of Asia. It is well-suited for grow well in subtropical climates, with temperatures ranging between 50-85°F. The plant thrives in well-draining soil that is rich in organic matter. It requires full sun to partial shade and protection from strong winds.
Watering needs
The golden flowered mallow requires regular watering, especially during the growing season. The soil should be kept moist, but not waterlogged, which can lead to root rot. Reduce watering during the dormant phase to prevent overwatering and encourage flower growth.
Fertilization
Abutilon auritum requires regular fertilization to promote growth and flowering. Fertilize the plant with a balanced fertilizer every four weeks during the growing season, as per the instructions on the fertilizer package. Avoid over-fertilization, which can lead to salt build-up and damage the plant’s roots.
Pruning
Pruning the golden flowered mallow is essential to encourage bushy growth, promote flowering, and keep the plant healthy. Prune the plant in the late winter or early spring before new growth appears. Remove all dead, damaged, or diseased stems. Cut back the remaining stems by one-third to encourage branching and promote a bushy growth habit. Remove any crossing or rubbing branches to shape the plant.
Propagation of Abutilon auritum (Wall. ex Link) Sweet
Abutilon auritum (Wall. ex Link) Sweet, commonly known as Indian mallow or velvetleaf, is a fast-growing, evergreen shrub that originates from Southeast Asia. It can reach a height of 3-4 meters and spreads up to 2 meters in width. It is a popular ornamental plant due to its attractive large, heart-shaped leaves and bright yellow flowers.
Propagation Methods
Abutilon auritum can be propagated from seeds, cuttings, and layering.
Seeds
Seeds are the most common method of propagation for Abutilon auritum. Collect mature seeds from the mother plant. Sow the seeds in a well-draining potting mix in a seedling tray. Water the seeds lightly and maintain them in a warm, but not too hot, place. Germination can take up to 3-4 weeks, but can be hastened by soaking the seeds in warm water overnight before planting. Once the seedlings emerge, transplant them into pots and grow them to the desired size.
Cuttings
Abutilon auritum can be propagated with semi-hardwood cuttings taken from the mother plant. The best time to take cuttings is in late spring or early summer. Cut a 6-8" piece of semi-hardwood from the mother plant, remove the lower leaves, and dip the cut end into rooting hormone powder. Plant the cutting in a pot filled with well-draining potting mix and water thoroughly. Place the pot in a warm, bright but indirect light area, and cover it with plastic to create a greenhouse-like environment for three weeks. Check for new roots after 4-6 weeks before transplanting the cutting into bigger pots.
Layering
Layering is a way to grow new plants from the existing ones while they are still attached to the parent plant. Choose a long, flexible stem and make a small incision or wound just below a leaf node. Dust the wound with rooting hormone and cover the wound with soil. The incised area where skin has been scraped or peeled from the stem start to form roots. Once the roots are formed, the stem may be separated from the parent plant and placed in a pot filled with well-draining potting mix and water thoroughly.
Propagation of Abutilon auritum requires some patience and care, but it is relatively straightforward. With the right environment and care, propagation can yield beautiful and healthy plants to enjoy for years to come.

Diseases
Leaf-curling: Leaf-curling is a common disease that is characterized by curling and distortion of leaves. This disease is caused by the Abutilon mosaic virus, which is transmitted by aphids. To manage leaf-curling, remove any infected plants and control aphid populations through regular spraying with insecticide.
Leaf spot: Leaf spot is a fungal disease that appears as circular, black or brown spots on leaves. This disease is caused by excess moisture and poor air circulation. To manage leaf spot, remove any infected leaves and keep the soil as dry as possible, while providing adequate air circulation.
Pests
Spider mites: Spider mites are tiny pests that feed on the plant's sap, causing yellowing and wilting of leaves. To manage spider mites, regularly spray the plant with an insecticide and keep the plant well-watered to prevent water stress.
Whiteflies: Whiteflies are another common pest that affects Abutilon auritum. They suck on the plant's sap, causing stunting and yellowing of leaves. To manage whiteflies, regularly spray the plant with an insecticide and introduce natural predators such as ladybugs to control their population.
By paying attention to these common diseases and pests, you can help safeguard your Abutilon auritum plants and keep them healthy and looking their best.
