Keep gardenia radicans healthy and beautiful by fertilizing regularly. Follow these simple steps, and gather together fertilizer, water-soluble fertilizer, a garden rake and a trowel.Continue Reading
Purchase a 5-15-10 fertilizer for your gardenia radicans. Apply it during the early spring when the plant starts to grow. Using a rake, carefully mix the fertilizer into the top 6 inches of soil.
The plant needs to be fertilized at least three times a year. After the spring fertilization, repeat the process at midsummer and late summer. Never add fertilizer in the fall. New growth is easily damaged during temperature drops.
If the plant does not grow or produces yellowed leaves, test the soil. The pH needs to be between 5.0 and 5.5 for a healthy gardenia radicans plant. A lack of water also causes the plant to wilt and look unhealthy. The soil needs to be moist and well drained. Water the plant thoroughly once or twice a week.
Add water-soluble fertilizer or fish emulsion to the soil to increase the acidity and improve the growth of the plant. Apply this fertilizer during the plant's growing season and in conjunction with the primary fertilizer.
