🌱 Fertilizer

The best time to fertilize a Kedah gardenia is in early spring, when it is coming out of dormancy. This supports overall growth and the development of flowers. Feeding the plant improves the foliage, stems, and branches while encouraging large, vibrant, and long-lasting blooms. It also helps move nutrients from the roots to the flowers and enhances the plant’s health and resistance to disease.
