Hibiscus Care Instructions
- 1). Select a location that receives sunlight. The hibiscus needs a temperature range above 50 degrees Fahrenheit to survive. They grow best where they receive at least six to eight hours of sunlight.
- 2). Find the soil pH with a testing kit. Add sulfates, phosphates or lime to adjust the pH levels appropriately. Hibiscus plants grow best in soils with a pH between 6.5 and 5.5. Follow the directions on these products to add them properly to the soil.
- 3). Add a fertilizer to the hibiscus once a month during the growing season between the last and first threat of frost. Use a 12-4-18 fertilizer for best results; apply it according to the fertilizer instruction label.
- 4). Water the hibiscus plant when the soil feels dry. The soil needs to remain moist for the plant to grow.
- 5). Apply a layer of mulch around the hibiscus to prevent weeds from growing and to maintain moisture.
- 6). Add an insecticidal soap to the hibiscus plant if you notice insects. Insects such as scale, mealy bug, white fly and aphid thrive on these types of plants.
- 7). Prune the hibiscus in the early spring with pruning shears. Remove dead and diseased wood, branches that rub against each other and droopy foliage.
