The Hibiscus

The hibiscus is the unofficial national flower of Vanuatu.   This five petaled beauty can grow to a height of 8 feet, and is often used for property boundaries.

Now is a great time for buying a potted hibiscus from Canadian garden centres to have on hand for 2021 World Day of Prayers services and events. In the meantime, it can add a tropical flair to Canadian gardens.

Growing Hibiscus in Containers

Many people who are growing a hibiscus plant choose to do so in a container. This allows them to move the hibiscus plant to ideal locations, depending on the time of year. Provide the plants with at least six hours of sunlight, especially if you want to see those lovely blooms. Although warm, humid conditions are ideal for tropical hibiscus, you may want to provide a little afternoon shade when it’s overly hot.

Again, containers make this easy to do. Hibiscus plants prefer a cozy fit when growing in a container. This means that they should be slightly root bound in the pot and when you do decide to repot, give the hibiscus only a little bit more room. Always make sure that your growing hibiscus plant has excellent drainage.

Temperatures for Growing Hibiscus

When you care for a hibiscus, you should remember that hibiscus flower best in temperatures between 16-32 C. (60-90 F.) and cannot tolerate temps below O C. (32 F.). In the summer, your hibiscus plant can go outside, but once the weather starts to get near freezing, it’s time for you to bring your hibiscus indoors.

Watering Hibiscus

When hibiscus plants are in their blooming stage, they require large amounts of water. Your hibiscus will need daily watering in warm weather. But once the weather cools, your hibiscus needs far less water, and too much water can kill it. In the winter, water your hibiscus only when the soil is dry to the touch.

Fertilizing Hibiscus

A growing hibiscus plant needs lots of nutrients in order to bloom well. In the summer, use a high potassium fertilizer. You can either use a diluted liquid fertilizer once a week, a slow-release fertilizer once a month or you can add a high potassium compost to the soil. In the winter, you don’t need to fertilize at all.
