Your Guide to Propagating Hibiscus Shrubs from Cuttings
With their vibrant, tropical blooms, hibiscus shrubs have always been among my top plant choices. Although each flower only lasts a single day, these shrubs can produce a stunning array of blooms throughout the year, contributing to their reputation as one of the best flowering shrubs available.
If you're already familiar with caring for hibiscus and want to expand your collection, propagation is an ideal solution. Thankfully, all hibiscus varieties—whether tropical or hardy—can be easily propagated by taking softwood cuttings from fresh, new growth.
Whether you're looking to add another swamp-rose mallow, Hibiscus moscheutos, to your garden or share a brightly colored tropical hibiscus, Hibiscus rosa-sinensis, with a neighbor, taking cuttings is a fun, free way to create more plants. Here, seasoned gardeners share their insights on propagating hibiscus and offer tips to help you cultivate healthy new plants.
Steps for Propagating Hibiscus Plants
Hibiscus shrubs come in a variety of shapes, sizes, and hardiness levels. No matter which species or variety you have, softwood cuttings are a straightforward and economical method to create additional plants. The best time to take these cuttings is in spring or early summer when the plants are lush and vibrant.
If you don't yet own a hibiscus shrub, you can purchase hibiscus starter plants online from Walmart.
Cuttings from Hardy and Tropical Hibiscus
Hibiscus plants can be categorized into two main types, both known for their large, colorful blooms and often contrasting petals.
'Hardy hibiscus varieties are resilient to cold, surviving frost and snow during winter,' explains Tatiana Anderson, a plant expert and co-founder of Top Tropicals.
These hardy types can usually thrive in US hardiness zone 4 and higher. 'Many native hibiscus species, including swamp-rose mallow, Hibiscus moscheutos, can be cultivated in both cooler and warmer climates, flourishing throughout much of Florida,' Tatiana adds.
'Tropical hibiscus species are more delicate, thriving best in warmer, southern areas, and generally doing well in US hardiness zone 9 and above.' While it's possible to grow them in cooler zones, they will need protection during the winter months.
Fortunately, both hardy and tropical hibiscus varieties can be propagated through cuttings, making it a great option for anyone looking to expand their plant collection.

Timing for Taking Hibiscus Cuttings
Softwood cuttings are taken from new, fresh growth. Because of this, it's best to gather these cuttings from mid-spring to early summer, typically around May, June, or July, when the shrub is producing new stems, leaves, and flowers.
Choose a mild, dry day to take your cuttings, selecting several healthy, vigorous stems of new hibiscus growth that are green and fresh.
How to Take Hibiscus Cuttings
- Start by filling a small pot—no larger than 4 inches in diameter—with fresh potting soil mixed with grit or perlite. Water the pot, ensuring it drains properly. Set this pot aside.
- Select four or more stems for cutting using clean, sharp pruning snips available from Walmart. These stems should come from new, lush green growth and ideally measure between 6 to 10 inches long. Cut just below a leaf node.
- Once you have your cuttings, remove most of the leaves from each stem, leaving just one or two small leaves at the top.
- Before planting your cuttings into the prepared pot, you can dip the bottom inch of each cutting into rooting hormone powder from Amazon. While this step isn't usually essential, it can help speed up the rooting process.
- Using a thin, blunt tool, create small holes in the soil for your cuttings. Make sure that half of each stem is above the soil. It's best to plant four to six cuttings in a single pot, ensuring the leaves do not touch.
- Cover the pot with a sandwich bag to retain warmth and moisture, and place it in a partially shaded area.
- Within eight weeks, roots should begin to develop. After that, you can transfer each hibiscus cutting to a new pot with fresh soil to encourage further growth.

Frequently Asked Questions
Can I take cuttings from a tropical hibiscus plant indoors?
Yes, you can take tropical hibiscus cuttings whether they are grown indoors or outdoors.
