How to keep Cassia Didymobotrya.
Light
The african senna does best when exposed to ample light for most of the day. Its natural habitat is in places with high light intensity. Both excessive and insufficient light can hinder its healthy growth, affecting leaf color and the timing of flowering. Likewise, at every stage of growth, light is an essential requirement for its development and vitality.
Temperature
African senna originates from Africa and grows best in temperatures of 68 to 100 °F (20 to 38 ℃). It adapts to varying seasonal temperature changes. In colder conditions, make sure the plant is not subjected to frost.
Fertilizer
The best time to fertilize an African senna is in early spring, when it is coming out of dormancy. This encourages overall growth and flower development. Fertilizing improves the foliage, stems, and branches, and promotes large, vibrant, long-lasting flowers. It also helps move nutrients from the roots to the flowers and enhances the plant’s health and resistance to disease.
