A Guide to Nurturing Your Beautiful Hibiscus Plants

The hibiscus flower is a classic tropical bloom that evokes images of sunsets, beaches, and fruity drinks. Luckily, Powell River’s warm climate allows for the growth of hibiscus plants even though it is not a typical tropical rainforest environment. Although most hibiscus plants are annuals and cannot survive sub-zero winter temperatures, there are some cold-hardy varieties available that can be planted as perennials. The “Holy Grail” is one such plant that can withstand the coldest temperatures that Powell River’s climate can subject it to. With 9-inch bright red blooms and deep green foliage with an almost black tint, the plant can grow up to five feet in height and spread. Although it only blooms in early August, it is well worth the wait.

While hibiscus plants require a bit more attention than other flowers, mastering the basics of hibiscus care isn’t too difficult, and their vibrant blooms make them worthwhile. The flowers bloom repeatedly from spring until fall, making them a great addition to any garden. We have compiled a hibiscus care guide so that you can grow your own hibiscus confidently at home.

Hibiscus can be grown in containers or outdoor garden beds, but most people find it easier to care for them in containers. Container gardening provides the flexibility to move the plants around to ensure that their needs are met. Additionally, during the colder months, you can bring the plants indoors to overwinter them and enjoy them for a second summer. When selecting a container, choose one that is not too large, as hibiscus plants prefer a snug fit around their roots. A smaller pot with drainage holes works best. If keeping the plant indoors, place it on a sunny windowsill, but be careful not to let it touch the glass, as the sun can heat the windowpane and scorch the plant.

If you have hibiscus plants in containers, it’s important to fertilize them more often than those planted in garden beds. During the blooming period, they should be fertilized once a week, while garden hibiscus can be fertilized every two weeks. Avoid using too much phosphorus as it can harm your hibiscus. Opt for slow-release 14-14-14 fertilizer or one that’s specially formulated for hibiscus plants. Fertilizers with some magnesium and iron can help your hibiscus bloom better.

When planting hibiscus in your garden, make sure to leave 2-3 feet of space between each plant. Hibiscus plants grow quickly during summer, so they will fill up space nicely. Test your soil’s pH level to ensure it’s slightly acidic. If it’s alkaline, mix in some loam to create ideal conditions for your hibiscus.

Warm water is best for watering your hibiscus plants. Cold water from the hose can shock them, so use warm tap water instead. Your hibiscus will need frequent watering during summer, but be sure not to water them excessively as their roots may become waterlogged. Container hibiscus should be watered daily, while garden hibiscus needs watering every other day. Overwintering hibiscus indoors requires you to wait until the soil dries out before watering again.

Hibiscus plants need plenty of direct sunlight to bloom well. Ensure they get at least 8 hours of direct sun every day. Although they can tolerate some partial shade, their blossoms won’t be as impressive as those in direct sunlight. If you plant hibiscus in your garden, ensure it’s in a spot where it won’t be shaded by tall trees or fences. Container hibiscus can be moved around to ensure it’s getting enough sun, so keep an eye on it.

Additional Tips for Taking Care of Your Hibiscus Plant
Apart from the basic hibiscus care you need to know in Powell River, there are a few extra tips that can help you maintain the health and happiness of your plant. One of the most important things to watch out for are pests such as aphids, spider mites, and whiteflies that may feed on hibiscus plants. In case of an infestation, you can use a simple insecticidal soap solution made of castile soap and water to get rid of them.

For perennial hibiscus plants, pruning once in spring can promote future blooms. Start by removing about one-third of the branches, beginning with those that look weak or awkwardly jut outward, and leave behind three or four sturdier main branches. If you notice the leaves turning yellow, you may need to cut back on watering, particularly during the winter months for indoor plants.

It’s best to avoid clay pots as they can make the soil more alkaline over time. Instead, go for plastic or stone pots when planting hibiscus. Although hibiscus care may require some effort, the stunning blooms that appear for months on end make it all worthwhile. By watching your plant’s growth and colouring and seeking advice from experts when needed, you can ensure that your hibiscus thrives.
