The Ultimate Guide to Propagating Hoyas: A Green Thumb's Delight


If you're a plant enthusiast or just looking to expand your indoor jungle, hoyas are a fantastic addition to your collection. These resilient and striking succulents, commonly known as wax plants or wax flowers, are not only beautiful but also relatively easy to propagate. Whether you're a seasoned gardener or a beginner, this guide will take you through the fascinating world of hoya propagation, helping you grow your own thriving hoya plants.

What is a Hoya?

Hoyas are a genus of tropical and subtropical flowering plants belonging to the family Apocynaceae. With over 200 species, hoyas are native to Southeast Asia, Australia, and some Pacific islands. What makes them stand out are their unique and fragrant star-shaped flowers that often resemble porcelain, wax, or lace. The leaves of hoyas are typically thick and fleshy, making them excellent choices for indoor gardening.

Why Propagate Hoyas?

Propagation is the process of creating new plants from existing ones. There are several reasons why you might want to propagate your hoyas:

1. Expand Your Collection: Propagating hoyas allows you to create more plants from a single mother plant, giving you a greater variety of species and cultivars in your indoor garden.

2. Share the Love: Propagated hoyas make excellent gifts for fellow plant lovers, allowing you to share the beauty of these plants with others.

3. Insurance Policy: If your hoya encounters any issues like disease or pests, having propagated plants can serve as a backup.

Now that you know why propagating hoyas can be beneficial, let's dive into the different methods you can use to propagate these lovely plants.

 Hoya Propagation Methods

There are three primary methods for propagating hoyas:

1. Stem Cuttings

Stem cuttings are the most common and straightforward way to propagate hoyas. Here's how you can do it:

1. Select a Healthy Stem: Choose a healthy stem that is at least 6 inches long and has several nodes (the small bumps where leaves and roots grow).

2. Cut the Stem: Use a sharp, clean pair of scissors or pruning shears to cut the stem just below a leaf node.

3. Let the Cutting Callus: Place the cutting in a dry, shady spot for a few days to allow the cut end to callus. This helps prevent rot when you plant it.

4. Plant the Cutting: Plant the cutting in a well-draining potting mix. You can use a mix of perlite and potting soil to provide good aeration.

5. Water and Wait: Water the cutting lightly and keep it in indirect sunlight. Over time, roots will develop, and a new hoya plant will start to grow.

2. Leaf Cuttings

Leaf cuttings are another method for propagating hoyas. While it may take longer for the new plant to develop, it can be a fun experiment for avid gardeners. Here's how to do it:

1. Select a Healthy Leaf: Choose a healthy, mature leaf from your hoya plant.

2. Cut the Leaf into Sections: Cut the leaf into sections, each containing a vein. Each section should be around 2-3 inches long.

3. Let the Sections Callus: Allow the cut ends of the leaf sections to callus for a few days.

4. Plant the Sections: Plant the leaf sections, cut-side down, in a well-draining potting mix.

5. Water and Wait: Water the sections lightly and provide indirect sunlight. Over time, small plantlets will sprout from the cut ends of the leaf sections.

3. Air Layering

Air layering is a more advanced propagation method but can be highly successful for hoyas with woody stems. Here's how to do it:

1. Select a Branch: Choose a healthy, woody branch from your hoya plant.

2. Make an Incision: About 12-18 inches from the tip of the branch, make a small incision around the stem's circumference. Remove a small section of bark.

3. Apply Rooting Hormone: Dust the exposed area with rooting hormone to encourage root growth.

4. Wrap with Moss: Pack damp sphagnum moss around the exposed area and cover it with plastic wrap or a plastic bag, securing it with twine or a rubber band.

5. Monitor and Wait: Keep the moss consistently moist and watch for roots to form within a few weeks. Once roots have developed, carefully cut the branch below the rooted area and plant it in a separate pot.

Caring for Propagated Hoyas

Once your hoyas have been successfully propagated, they require similar care to mature hoya plants:

1. Light: Hoyas thrive in bright, indirect sunlight. Avoid direct sunlight, especially in the hottest parts of the day, as it can scorch their leaves.

2. Watering: Allow the top inch or so of the potting mix to dry out before watering. Be cautious not to overwater, as hoyas are susceptible to root rot.

3. Temperature and Humidity: Hoyas prefer temperatures between 60-80°F (15-27°C) and moderate humidity. They can tolerate some variations, but avoid exposing them to extreme cold.

4. Fertilizing: Feed your hoyas with a balanced liquid fertilizer diluted to half strength during the growing season (spring and summer). Reduce or stop fertilizing during the dormant season (fall and winter).

5. Repotting: Repot your hoyas when they become root-bound, typically every 2-3 years. Use a slightly larger pot with well-draining soil.


Propagating hoyas can be a rewarding and enjoyable journey for plant enthusiasts of all levels. Whether you choose stem cuttings, leaf cuttings, or air layering, the key to success is patience and care. As your propagated hoyas grow and thrive, you'll have the satisfaction of knowing that you've expanded your collection and shared the beauty of these unique plants with others. So, roll up your sleeves, grab your gardening tools, and get ready to propagate your hoyas—it's a green thumb's delight!
