Ochna integerrima prefers full sunlight to grow well and produce beautiful flowers. It can tolerate some shade, but too much shade can result in poor growth and fewer flowers.

If grown indoors, place it near a bright window where it can receive at least 6-8 hours of sunlight per day. If grown outdoors, place it in a location that receives full sun to partial shade, and protect it from strong, direct sunlight during the hottest part of the day. 


Ochna integerrima can grow well in a variety of soils, as long as it is well-draining and rich in organic matter. In India, a soil mixture of red soil and compost in equal parts is recommended. The soil pH should be slightly acidic, ranging from 5.5 to 6.5. 


In terms of water requirements, Ochna integerrima prefers to be kept moderately moist but not waterlogged. Water the plant thoroughly when the top inch of soil feels dry to the touch.

During the hot and dry summer months in India, the plant may require more frequent watering. 


Ochna integerrima prefers warm temperatures and can tolerate some cold temperatures, but not freezing temperatures. In India, it can be grown outdoors year-round in most regions, as long as it is protected from extreme heat and cold.

Prune Ochna integerrima after flowering to maintain its shape and size. Remove any dead, damaged, or diseased branches, as well as any branches that are crossing or rubbing against each other.

To promote bushier growth, pinch back the tips of new growth. 

Pest and Diseases 

Ochna integerrima is generally a low-maintenance plant, but it can be susceptible to some pests and diseases. Common pests include aphids, mealybugs, scale insects. 

These can be controlled with insecticidal soap or neem oil.

Diseases such as powdery mildew and root rot can be prevented by providing good air circulation and avoiding overwatering. If these issues arise, treat them with appropriate fungicides or by adjusting watering practices.
