Tropical Hibiscus are a stunning display of colour on any patio. Their bright beautiful flowers definitely make you feel like you've gone to the tropics! With these few easy care tips you can have beautiful flowers all summer long.
Container - You can keep your hibiscus in the growing container you purchased it in. However it will thrive if it is potted into a larger container. Use a well-draining soil mix, and make sure the container has drainage holes.
Sunlight - Tropical hibiscus require at least 6-8 hours of direct sunlight each day.
Temperature - Tropical hibiscus prefer warm temperatures between 60-85°F (15-29°C). Be careful not to leave your hibiscus outdoors on the cool nights of spring as this can delay the flower buds from forming.
Water - Water your tropical hibiscus when the top inch of soil feels dry to the touch. Avoid overwatering, as this can lead to root rot. Allow excess water to drain from the bottom of the container.
Fertilizer - Use a balanced fertilizer, such as a 10-10-10 formula, and apply it every two weeks during the growing season. Follow the manufacturer's instructions for dosage or even slightly diluted as over fertilizing hibiscus plants will result in fewer or no blooms or even yellow, dropping leaves.
Tropical hibiscus are often grown in southwestern Ontario as an annual and are discarded at the end of summer. If attempting to overwinter a hibiscus move it indoors before the first frost. Place it in a cool, bright location with reduced watering (and no fertilizing) until growth resumes in the spring. It will most likely drop most of it's leaves when brought indoors as the drastic reduction in sunlight will cause it to have a shock. With a bit of care and luck it will most likely return to its healthy condition in the spring when the sunlight is better.
