If you own a hibiscus plant, you are most likely expecting it to bloom into a bright-colored flower at some point. Unfortunately, while they are easy plants to care for, it may take some extra work to get the unique flower to bloom.
The hibiscus plant is a perennial, allowing it to bloom only yearly. This is usually during the peak of the growing season in August.
However, if you own a tropical hibiscus plant, it will bloom all year round, with blooms normally lasting for a few days.
When Will My Hibiscus Bloom?
Depending on the type of hibiscus you own, it will be different when it blooms. For example, if your hibiscus is a perennial plant, it will only bloom once a year in the growing season.
A tropical hibiscus, however, will bloom all year-round consistently. Each bloom for these plants will only last one day.
Most hibiscus plants found in stores or grown by seeds usually are perennial.
How Long Do Hibiscus Blooms Last?
A hibiscus flower will appear bright and large, normally only lasting for one to three days. They will open in the morning and wilt when the sun has set.
How Do I Get My Hibiscus to Bloom?
If your hibiscus is not blooming, it may be lacking something. If it is not getting enough light or water, or even if there are pests, your plant will not bloom.
Sunlight And Lighting
If your hibiscus is not in direct sunlight, it will cause it to not bloom. The plant needs direct sunlight since it is a tropical plant. Therefore, the more sunlight it gets throughout the day, the more likely it will bloom. More on Hibiscus plant light requirements.
If you fertilize the hibiscus flower too much, this will lead to an adverse effect on the plant. This is because the phosphorous in the fertilizer normally help the blooming process. However, it does the opposite for hibiscus.
If there is too much phosphorus, the plant will not be able to absorb any nutrients and will not even absorb the phosphorus. This stunt in nutrients will cause your hibiscus to not bloom. Instead, you may notice droopiness along with yellowing in the leaves.
It is important to flush your plant’s soil completely and not fertilize it until the next growing season. Even though it has issues with phosphorous, you must fertilize your hibiscus plant, as they need many nutrients to thrive and bloom.
Be sure to use a general fertilizer like 10-10-10. It is important to fertilize the hibiscus during the growing season rather than the winter. Details on choosing hibiscus plant food.
It is important to prune dead or dying parts of your perennial hibiscus plants to promote growth and blooming. Cut back any brown or yellow parts to allow for new growth.
If you have a tropical hibiscus, it is best to prune in the spring. Learn more about when to prune hibiscus plants.
Hibiscus plants normally need a lot of water throughout the week. Since they are tropical plants, they constantly need water to grow properly and bloom.
However, if you water your plant frequently, it is important not to over-water it. If your plant is in a pot, be sure it is not in any standing water. It should be in a well-draining pot.
If you have planted your hibiscus in the ground, you should ensure the soil is well-draining and will not allow water to build up underneath the plant.
If you find pests on your hibiscus, this will stop any growth and blooming. Therefore, it is important to inspect your plants for any pests.
If you notice pests on your plant, you should prune any infected parts of the plant and thoroughly wash it. After that, you should use insecticide or neem oil to kill and keep pests away.
Why Do My indoor Hibiscus Flowers Only Bloom a Few Days and Then Die?
Question: I have a hibiscus tree I got in Florida. I keep it indoors where it gets morning sun. The flowers on it are beautiful, but they open only one bloom at a time. If one bud starts to open before the flower on the same cluster has fallen, the bud will fall. Some of the leaves turn yellow. I water it well. What is wrong?
Answer: I have four hibiscus trees from Florida and know that the only way to control bud dropping is to decrease watering as soon as the first buds form. From the yellowing of the leaves (follow the link), but I think you are watering too much or too often. These plants are shrubs in Florida and they do not need coddling. Try letting the top of the soil dry before you water and then soak.
Why Does My Hibiscus Drop Buds?
Question: My hibiscus (Hibiscus rosa-sinensis) plants look healthy, but the blossom buds form, then drop before opening. Is there a remedy?
Answer: No doubt the trouble is bud drop, not caused by fungus, but by poor growing conditions. If this hibiscus is grown in soil deficient in plant food or in very wet or very dry soil, it will drop its buds. The trouble will disappear if growing in well-drained soil with adequate plant food and humus. More on hibiscus flower buds here.
