Hoya plants, fondly known as the millionaire plant or wax plant, are popular indoor tropical plants that have captured the hearts of many gardening enthusiasts. These plants are known for their lovely, fragrant flowers and their leathery leaves, making them a charming addition to any indoor space. Propagating hoya plants is a simple process that allows you to create new plants from your existing specimens, making the joy of owning these stunning plants even more rewarding.

The most common method used for propagating hoya plants is through stem or leaf cuttings. This method is relatively easy and has a high success rate, allowing even novice gardeners to effortlessly expand their collection of these beautiful and exotic plants. In this article, we’ll explore some effective propagation techniques to help you create new hoya plants from your existing ones, ensuring that your indoor garden remains lush and vibrant.

Hoya Millionaire Plant Overview

The Hoya Millionaire Plant, also known as Hoya Cumingiana, is an attractive houseplant with cascading vines and beautiful clusters of star-shaped flowers. Native to tropical regions of Asia, these plants thrive in warm, humid environments and are popular choices for indoor gardening enthusiasts.

One of the reasons Hoya Millionaire plants are appealing to home gardeners is their low maintenance nature. They can tolerate a variety of light conditions, but they prefer bright, indirect sunlight. Keep in mind that exposure to direct sunlight may cause leaf discoloration, especially during propagation.

In terms of watering, this plant prefers a well-draining soil mix and should be allowed to dry out between waterings. Overwatering can cause the roots to decay, which is commonly referred to as root rot, whereas failing to provide the plant with adequate water enough can cause the leaves to droop. It’s best to provide the plant with adequate water thoroughly and then wait until the top two inches of soil are dry before watering again.

When it comes to feeding, these plants benefit from a balanced liquid fertilizer applied once a month during the growing season. During the winter months, however, reduce or withhold fertilization altogether as the plant enters a rest period. Similar to other Hoyas, the Millionaire plant is a climber, so providing a support for the vines will encourage vertical growth and an attractive display.

Propagation of Hoya Millionaire plants is often achieved through stem cuttings, which can be taken during spring when the plant exhibits active growth. Cut a healthy green stem with at least two or three leaf nodes, removing the leaves near the bottom end of the cutting. Dip the cut end into rooting hormone and then place it into a well-draining soil mix. Keep the soil consistently moist, misting every 2-3 days to maintain root development. The cutting should root and begin to show new growth within a few weeks.

Hoya Millionaire plants offer an easy-to-care-for, attractive addition to any home garden. By following the basic care guidelines for light, watering, feeding, and propagation, you can enjoy the lush cascades and stunning flowers of this tropical beauty in your own space.

Propagation Methods

Stem Cuttings

Propagating hoya millionaire plants through stem cuttings is a popular and simple method. To do this, take a healthy stem cutting from the mother plant, about 4-5 inches long, using a sterile knife or pruners. Make sure the cutting has at least a couple of leaves and a node, which is the point where a leaf stems from the main stem.

Before planting, remove the lower leaves and let the cutting dry for a few hours or overnight. This helps to avoid rotting when it’s planted. You can choose to propagate the stem cutting in water or soil:

  • Water propagation: Place the cutting in a water-filled container with the cut end submerged. Make sure the leaves don’t touch the water. Refresh the water every few days to prevent bacteria growth. Once roots develop, transplant the cutting into a well-draining potting mix.
  • Soil propagation: Plant the cutting in a well-draining potting mix, with the bottom node buried in the soil. Keep the soil moist, but not overly wet, to reduce the chance of rot. Avoid direct sunlight and place the potted cutting in a warm and humid environment.

It’s important to be patient while waiting for roots to develop, as this process can take several weeks.


Layering is another technique for propagating hoya millionaire plants. This method involves encouraging roots to grow on a stem section while it’s still attached to the parent plant. Follow these steps for successful layering:

  1. Identify a healthy, long stem on the hoya plant that’s close to the soil surface.
  2. Select a portion of the stem with a node, and gently remove any leaves near the node.
  3. Create a small incision on the stem just below the node, which will encourage root growth at that point.
  4. Secure the incised stem to the soil using a hairpin, U-shaped metal stake, or a small rock, ensuring the node is in contact with the soil.
  5. Keep the soil consistently moist, allowing roots to develop at the node.

After several weeks, once roots have established, cut the stem from the mother plant and transplant the new plant into its own container filled with well-draining potting mix. As with stem cuttings, be patient and take care not to overwater during the rooting process.

Step by Step Propagation Guide

Gathering Supplies

To propagate your Hoya millionaire plant, you’ll need to gather a few essential supplies. These include a sharp pair of clean scissors or pruning shears, a small pot with drainage holes, some well-draining potting mix (e.g., a mixture of peat moss and perlite), and optionally a rooting hormone to help stimulate root development.

Choosing Healthy Plant Material

The first step in the propagation process is to select a healthy stem from your Hoya millionaire plant. Look for a green, robust piece of active growth, preferably with a few leaves already present. Avoid using withered stems or leaves that are yellow or brown, as they may be less likely to root successfully.

Preparing the Cuttings

Once you’ve selected a healthy stem, use your clean scissors or pruning shears to make a clean cut just below a node (the point where a leaf meets the stem). Remove any leaves from the bottom few inches of the cutting to expose the nodes where new roots will form. Optionally, you can dip the freshly-cut end of the cutting in a rooting hormone to increase the chances of successful propagation.

Rooting and Potting

Next, fill your small pot about 3 quarters of the way with the well-draining potting mix you prepared earlier. Insert the Hoya cutting into the soil, making sure the node where you removed leaves is covered. Securely pack the soil around the stem to provide support. Keep the soil moist but not waterlogged, and maintain a warm, bright environment for your cutting.

After a few weeks, you should see new roots forming at the base of the cutting. Once the roots have developed and grown a few inches, it’s time to transplant the cutting into a slightly larger pot with fresh potting mix. Continue to care for your new Hoya millionaire plant as you would the parent plant, providing adequate light, water, and nutrients for optimal growth.

Caring for New Hoya Plants

Once you have propagated your hoya millionaire plant, it’s important to provide the right care for the newly established plants. In this section, we’ll discuss the watering requirements, light and temperature, and fertilization necessary for your new hoya plants to thrive.

Watering Requirements

New hoya plants need consistent moisture, but it’s crucial to avoid overwatering. Allow the top inch of soil to dry out between waterings, and then water generously. To prevent root rot, ensure the pot has drainage holes, and use a well-draining soil mix, such as a combination of peat moss and perlite. Misting the soil every 2-3 days can help maintain adequate moisture for root development. Remember that hoya plants are prone to overwatering, so always make sure the roots are not sitting in water for too long.

Light and Temperature

Hoya plants prefer a warm environment with indirect sunlight. For optimal growth, place them in a bright location but away from direct sunlight, which may cause leaf discoloration. Typically, hoya plants perform well in temperatures between 65°F and 80°F (18°C to 27°C). During the cooler months, protect your hoya plant from cold drafts by moving it to a warmer area or by increasing the air temperature around it.


To support continued growth and keep your hoya plant healthy, it’s essential to provide the right nutrients. Use a balanced, water-soluble fertilizer diluted to half the recommended strength, applying it every four to six weeks during the active growing season. Avoid over-fertilizing your hoya plant, as this can result in weak, soft growth and even damage the roots. Be sure to follow the fertilizer’s package instructions for the best results.

In summary, taking proper care of your new hoya plants involves consistent watering, providing the right light and temperature conditions, and supplying adequate nutrients. By adhering to these guidelines, you’ll set your hoya plants up for successful growth and enjoyment.
