With flowers that can grow as large as dinner plates, hibiscus plants are show-stopping additions to the garden and home. However, if you don’t have the space or proper climate, you may not be able to grow these plants in the ground outdoors. If that’s the case, you may be wondering if you can grow hibiscus in pots and containers.
Can You Grow Hibiscus Plants in Pots and Containers? Key Takeaways
Yes, you can grow some types of hibiscus plants in pots or containers. Gardeners located outside of the tropics often grow tropical hibiscus in pots. This allows you to grow the plants indoors or move them indoors once temperatures dip.
Picking a Container for Hibiscus Plants
If you want to grow a healthy hibiscus plant in a container, you’ll need to choose a proper pot. Consider factors such as the container size, material, and drainage holes.
Many tropical hibiscus plants can be grown in pots that are as small as ten inches in diameter. While you may need to refresh the soil in these pots every few years, the plants can thrive.
However, you can also grow hibiscus plants in larger pots, such as those that are 12 or 18 inches in diameter. If you plan to move your hibiscus plants between the indoors and outdoors, be aware that larger pots will be heavier and more challenging to move.
As far as material size goes, you have multiple options. Terra cotta, glazed ceramic, and plastic can all work well.
No matter what size and material you choose, your pot must have drainage holes that allow excess water to escape. A lack of drainage holes can lead to saturated soils and rotten roots.
Selecting a Potting Mix for Potted Hibiscus
While you can grow in-ground hibiscus plants in native soil, you shouldn’t grow potted hibiscus in soil. Instead, you should choose a soilless potting mix that is designed for container plants.
Since hibiscus plants like their soil moist but not wet, choosing a well-draining potting mix is important. If the mix doesn’t provide suitable drainage, plant roots may begin to rot.
Chunky materials such as perlite and pine bark fines will help increase the drainage in a soil mix. Adding sand to the potting mix can also help improve drainage.
While good drainage is essential, a proper hibiscus potting mix should also be able to hold a fair bit of moisture. This will allow the soil to stay damp in between waterings.
As far as pH goes, the mix should have a slightly acidic to neutral pH. This means the pH should be between 6.0–7.0.
Fertilizing Hibiscus in Pots and Containers
Most potting mixes provide few, if any, nutrients. Therefore, you should fertilize your potted hibiscus plants on a regular basis.
Choose a fertilizer designed for flowering plants and apply it once in the early spring, once in late spring, and again in mid-summer. Some suitable fertilizers include Fox Farm Tiger Bloom and Neptune’s Harvest Rose & Flowering Formula.
