Let’s dive in!

Growing Hoya Sarawak

While most plants require seeds or seedlings to start growing, the Hoya Sarawak can be produced from cuttings.

You should take stem cuttings from a healthy and mature plant to grow the Hoya Sarawak. 

Look for a stem with at least two sets of leaves, and make a clean cut below a node. Nodes are the points on the stem where leaves or roots emerge.

Once you have your cutting, remove the lower set of leaves, leaving just the top set. This will help reduce moisture loss and allow the cutting to focus on root development. 

You can dip the cut end of the stem in the rooting hormone to encourage root growth, but it’s not mandatory.

Next, plant the cutting in a well-draining potting mix. You can use a combination formulated explicitly for succulents or create your own by combining equal parts of the potting mix. 

Place the cutting in the soil, burying it about an inch deep, and gently firm the soil around it. Keep the soil slightly moist but not soggy to encourage root growth. 

Overwatering can lead to rot, so be careful not to drown the cutting. Place the pot in a warm and bright location, but avoid direct sunlight, as it can scorch the leaves.

Your Hoya Sarawak cutting should start developing roots within a few weeks with patience and proper care. 

Once the roots have been established, you can gradually introduce it to more light and start following the growth requirements.

Caring for Hoya Sarawak

Below, I’ll discuss the key factors that influence the growth rate of Hoya Sarawak. These factors can help you care for your plant to maximize its growth rate.

Light Exposure

Hoya Sarawak are tropical plants that thrive in bright, indirect light, making them ideal for placement near a window or in a room with plenty of natural light. 

This glossy wax plant prefers moderate to high levels of light. If your plant’s leaves become pale or yellowish, it may indicate it’s not receiving enough light. 

On the other hand, if the leaves become dark green and start to elongate, it may be a sign of excessive light exposure.

Rotate the plant every few weeks to ensure it’s getting the right amount of light to promote even growth.

Daytime light exposure shouldn’t exceed 10 hours, even during dormancy. This will prevent one side from becoming leggy and the other side from becoming shaded.

Remember, finding the perfect balance of light exposure is crucial in keeping your Hoya Sarawak healthy and thriving. 

So, observe your plant closely and make any necessary adjustments to provide it with the optimal lighting conditions it needs to flourish.

Temperature Levels

Hoya Sarawak thrives in warm and humid environments, making them perfect for tropical regions. Ideally, the temperature should be between 65°F (18°C) and 85°F (29°C). 

However, a healthy Hoya Sarawak plant can tolerate slightly higher or lower temperatures for short periods.

Protecting your plant from drafts and chilly temperatures is essential in colder months. Avoid placing them near doors or windows that may let in cold air. 

Similarly, ensure they’re not exposed to direct heat from radiators or air conditioning vents in hot summers.

Consider using a thermometer to monitor the conditions to ensure the optimal temperature for your Hoya Sarawak. 

You may also need to adjust the location of your plant during extreme weather conditions to provide an ideal temperature for a healthy growth rate.

Soil Quality

Hoya Sarawak prefers a well-draining medium or soil that allows water to flow easily. A mixture of perlite, peat moss, and potting soil works well for this plant.

Combine equal parts peat moss and potting soil and add perlite to improve drainage to create the ideal soil mixture.

This will prevent water from pooling at the roots, which can lead to root rot. The peat moss also helps retain moisture, ensuring your plant gets ideal hydration.

Please avoid heavy or compacted soil. This can restrict root growth and lead to suffocation of the roots. Loosen the soil mixture before planting your Hoya Sarawak to prevent this.

Additionally, inspect the soil moisture levels regularly. Hoya Sarawak prefers slightly moist soil, but don’t overwater your soil. 

By paying attention to the soil quality and moisture levels, you can create the perfect growing environment for your Hoya Sarawak. 

Humidity Levels

Hoya Sarawak requires environments with high humidity, as they’re native to regions with moist air. Maintaining humidity levels between 50% and 60% is ideal for your plant.

If the humidity drops below the required range, the plant may suffer dryness and wilting, while excessively high humidity can lead to issues like mold and rot.

Monitoring the humidity levels is essential to ensure your plant’s health. You can use a hygrometer to measure the humidity in the room where your Hoya Sarawak is located. 

Consider using a humidifier or placing a tray of water near the plant to increase the moisture in the air. This will help create the ideal humidity levels for your Hoya Sarawak.

Grouping your plants closer can also help increase humidity, as plants release moisture through transpiration.

However, humidity needs vary depending on the specific conditions of your home, garden, or office. 

Observing your plant closely and adjusting accordingly will help ensure that your Hoya Sarawak thrives in the correct humidity levels for optimal growth and overall health.

Watering Frequency

Hoya Sarawak prefers moist soil but not soggy conditions. Overwatering your plant can cause root rot and other issues, so striking the right balance is crucial.

You can use the finger test to determine when to water your Hoya Sarawak. 

Stick your finger about an inch into the soil or potting mix. If it feels dry, it’s time to water. Avoid watering for a few more days if it feels damp or moist.

Watering frequency may vary depending on various factors like temperature, humidity, and the size of the pot. 

During warmer months, your plant may require more frequent watering, while you can reduce the frequency in cooler months.


When done correctly, transplanting or transferring your Hoya Sarawak seedling can promote healthy root development and encourage overall plant growth. 

However, if done improperly, transferring can cause stress to the plant, impede growth, or kill the plant.

Before transplanting your Hoya Sarawak, choose the right size pot and well-draining soil. A tiny pot can restrict root growth, while an overly large pot can lead to soggy conditions.

When removing the plant from its current pot or potting mat, be gentle to avoid damaging the delicate roots.

Fertilizing Routine

Hoya Sarawak plants require regular fertilization to ensure they have essential nutrients for robust growth and vibrant foliage.

Choose a high-quality organic or inorganic fertilizer designed for houseplants to create a successful fertilizing routine. 

Generally, fertilizing once a month during the growing season (spring and summer) is recommended while reducing frequency in the dormant period (fall and winter).

Note that overfertilization can lead to salt build-up in the soil, causing damage to the roots. Follow the instructions on the packaging for dilution ratios and frequency of application. 

Common Issues and Pests

Hoya Sarawak can face common issues and be prone to pests that significantly influence its growth rate.

Root rot is a common issue affecting roots that are consistently exposed to soggy conditions. 

This makes the roots mushy and brown, ultimately causing the plant to wilt and die. To prevent root rot, provide well-draining soil and avoid overwatering your plant.

Another issue is yellowing or dropping leaves caused by various factors, like overwatering, nutrient deficiencies, or pest infestations.

Hoya Sarawak is also susceptible to common houseplant pests like mealybugs, scale insects, and spider mites that weaken the plant and cause damage to the leaves and stems. 

To combat them, inspect your plant regularly for signs of infestation and take immediate action using natural remedies like Neem Oil or chemicals, depending on your preference.

Propagation Methods

The following are two primary methods of propagating Hoya Sarawak.

Seed Propagation 

Seed starting can be a rewarding but time-consuming process. You need fresh seeds from mature Hoya Sarawak plants, ensuring they’re under one year old. 

These seeds must be sowed in a well-draining potting soil mix, providing warmth and humidity for germination. It can take several months for the seeds to sprout.

Cuttings Propagation 

This is a popular and relatively more accessible method. You only need stem cuttings from a healthy Hoya Sarawak plant, ensuring they have at least two nodes. 

You should dip the cutting edges in rooting hormone and plant them in a well-draining soil mix. With time and proper care, the cutting will develop roots and grow into a new plant.

How Fast Does Hoya Sarawak Grow?

The Hoya Sarawak has relatively slow growth compared to other houseplants. Don’t expect rapid expansion and wild overgrowth in your garden with this elegant beauty. 

On average, this unique plant can take several months or even a year to reach its full potential. 

However, the Hoya Sarawak can grow steadily with proper care and optimal conditions. 

It typically starts as a small cutting or young plant and gradually develops into a more mature plant with sprawling vines and beautiful foliage.
