It’s no secret that my happy place is on the coast and I’m a beach girl at heart. My beachy vibes run strong and hibiscus is my spirit flower. Where we live in zone 6b, growing hibiscus in pots is the closest thing I can get to my honeymoon memories of Maui.
But I’ll take it! I was at Produce Junction the other day and they had column hibiscus plants for sale featuring blooms in three different colors!
The pink and orange blossom combination stole my heart!
Now I am committed to helping this amazing hibiscus thrive outside on our deck all summer. (And later, hopefully I can keep it alive indoors over the winter!)
For best results, I decided to learn as much as I could about growing hibiscus in pots.
I figured I’m not the only northeast girl trying to grow a tropical garden, so here are my favorite hibiscus takeaways.
What do hibiscus look like?
Hibiscus flowers are tropical and very showy with five fluttery petals and a long pistil with five round stigma on the ends. A burst of yellow anthers adds a pop of eye-catching color and feathery texture. Hibiscus come in many color combinations, from pink, red, white, orange, yellow, and multicolor blends.
The hibiscus shrubs have woody stems and dark green almost glossy leaves. Flowers bloom for one day and then fall from the plant.
Is deadheading hibiscus necessary?
Most times, spent hibiscus flowers drop from the plant on their own. Deadheading hibiscus plants is not required to enjoy a continuous flow of blooms.
Should you fertilize hibiscus plants in containers?
Yes, fertilizing hibiscus while they’re flowering can help to increase blooming and general plant health. Consider a 10-10-10 fertilizer for new plantings and maintain with fertilizers delivering lots of potassium and a moderate amount of nitrogen. Hibiscus do not require as much phosphorous.
Choosing Containers When Growing Hibiscus in Pots
Keep in mind that hibiscus actually like their roots a bit crowded. Choose a container that is a bit bigger than the original pot that came with the plant. When potting up to a larger container, keep increasing by just a bit bigger each time.
More than anything, make sure your containers have drain holes to avoid standing water. Tropical hibiscus do like moist soil but would not like oversaturated soil.
If you get a lot of wind in your area, look for a heavier pot like a ceramic planter or large planting urn. Otherwise, any slightly larger decorative pot with drainage holes should do just fine!
How Often to Water Hibiscus in Pots
Tropical hibiscus plants generally prefer moist soil that isn’t soggy. For hibiscus grown in containers, consider using a moisture meter to help anticipate watering needs. You may need to water hibiscus growing in pots daily, every day, or every two days, depending on outdoor temperatures, rainfall, and how fast the soil dries in between waterings.
Hibiscus plants tend to have high water needs, meaning you should stay on top of checking them daily. Adequate watering helps to reduce stress on the plant and keep hibiscus blooming beautifully.
When to Fertilize Hibiscus in Containers
Plan to fertilize hibiscus regularly during the main growing season. You can fertilize when you first plant or bring hibiscus home. Then, plan to fertilize on a weekly basis or every other week with a water-in fertilizer. For slow-release fertilizer, reapply about every 8 weeks.
Which fertilizer is best for hibiscus?
You can use a tropical fertilizer like Pennington UltraGreen palm tree and hibiscus fertilizer or a bloom-boosting fertilizer like Miracle Gro Bloom Booster Flower Food.
When considering fertilizers, look for one with the most potassium (K), then nitrogen (N), and finally, not as much phosphorous (P).
That being said, a general liquid fertilizer can still benefit most plants as opposed to not fertilizing at all.
Protecting Hibiscus in Containers
Tropical hibiscus plants cannot withstand temperatures dipping down to 32 degrees. If your climate doesn’t allow for hibiscus tree, plant, or shrub to survive outdoors all year, plan to bring them inside for the winter.
Find a spot by a sunny window and/or supplement lighting requirements with LED grow lights.
Growing Hibiscus in Pots
Hibiscus flowers make me happy! Channeling tropical vibes in my own backyard is awesome with a hibiscus, even here in PA Zone 6.
I especially love going out and taking photos of my girls with their beautiful faces next to the huge hibiscus blooms.
Be sure to stay on top of watering and make sure the soil doesn’t get too dry. It’s okay for it to get a little dry between waterings, but definitely don’t let it dry out too long.
