It can tolerate a wide range of soil types, including sandy, loamy, and clay soils. The plant requires full sun exposure to grow and bloom well. It is recommended to plant the saplings during the rainy season in order to allow them to establish strong roots before the dry season.
Watering Needs
Grewia floribunda Mast. var. latifolia De Wild. requires moderate watering. The plant should be watered deeply every 7-10 days during the growing season. Watering should be reduced during the dry season, but the plant should not be allowed to completely dry out.

Disease and Pest Management for Grewia floribunda Mast. var. latifolia De Wild.
Grewia floribunda Mast. var. latifolia De Wild. is a shrub or small tree that belongs to the family Tiliaceae. Although this plant is generally healthy, it can get affected by some pests and diseases that may cause damage to the foliage, flowers, and fruits. Here are some of the common diseases and pests that might affect Grewia floribunda and ways to manage them:
Diseases
Powdery Mildew: Powdery mildew is a common fungal disease that affects the leaves, stems, and flowers of Grewia floribunda. It can cause the leaves to curl and turn yellow, and powdery white patches may develop on the surface of the foliage. To manage powdery mildew, you should prune the infected parts of the plant to improve air circulation, avoid overhead watering, and apply a fungicide containing sulfur or copper.
Leaf Spot Diseases: Leaf spot diseases are caused by different fungi that affect the leaves of the plant, causing small yellow spots that may later turn brown or black. In severe cases, the infected leaves may fall off, leading to defoliation. To manage leaf spot diseases, you should prune the affected parts, apply a fungicide, and improve the air circulation by thinning the canopy.
Root Rot: Root rot is a fungal disease that affects the roots of the plant, causing them to decay and blacken. This can lead to wilting, yellowing of leaves, and stunted growth. To manage root rot, you should avoid overwatering, improve the drainage, and prune the infected roots to prevent the spread of the disease. You can also apply a fungicide to the soil to prevent the growth of the fungus.
Pests
Scale Insects: Scale insects are tiny, oval-shaped insects that attach themselves to the stems and leaves of the plant, sucking the sap and causing yellowing, wilting, and stunted growth. To manage scale insects, you can prune the affected parts, wash them with a strong jet of water, or apply an insecticidal soap or oil spray to suffocate the insects.
Spider Mites: Spider mites are tiny sap-sucking pests that can cause yellowing, bronzing, and drying of the leaves of Grewia floribunda. They may spin webs on the underside of the leaves, making the plant look unsightly. To manage spider mites, you can spray the plant with water to improve humidity, prune the infested leaves, or apply an insecticide containing neem oil or pyrethrin.
Mealybugs: Mealybugs are soft-bodied, white insects that feed on the sap of the plant, causing wilting, yellowing, and distortion of leaves. They secrete a waxy substance that may attract black sooty mold. To manage mealybugs, you can prune the affected parts, wash them with rubbing alcohol, or apply an insecticide containing neem oil or pyrethrin.
By managing the diseases and pests that affect Grewia floribunda, you can ensure that your plant grows healthy, produces beautiful flowers, and bears fruits. Always use the recommended doses of pesticides and follow the safety precautions to protect yourself and the environment.
