Hibiscus plants are hardy and can grow in a variety of environments. The plants grow bright flowers with dark green leaves. The flowers will add color to your yard, as they bloom in many different colors–such as pink, red, yellow and purple. If you care for the plant properly, it will continue to bloom and produce beautiful flowers.
Things You'll Need
- pH testing kit
- Sulfates, phosphates or lime
- Insecticidal soap
- Pruning shears
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.
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.
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.
Water the hibiscus plant when the soil feels dry. The soil needs to remain moist for the plant to grow.
Apply a layer of mulch around the hibiscus to prevent weeds from growing and to maintain moisture.
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.
Prune the hibiscus in the early spring with pruning shears. Remove dead and diseased wood, branches that rub against each other and droopy foliage.
