Fertilization:
Fertilize your Rhinacanthus every 2-3 weeks during the growing season using a balanced fertilizer. Be careful not to over-fertilize, which can lead to excessive foliage growth at the expense of flower production.
Soil:
Rhinacanthus prefers well-draining soil that is rich in organic matter. A soil mix consisting of equal parts peat moss, perlite, and vermiculite should work well.
Sunlight:
Rhinacanthus prefers bright, indirect light. Avoid placing it in direct sunlight, which can scorch the leaves and flowers.

This fungal disease can cause brown spots to appear on Rhinacanthus leaves. To prevent leaf spot, avoid getting water on the leaves and ensure adequate air circulation around the plant. If leaf spot does occur, remove affected leaves and treat the plant with a fungicide.
