Hoya Macrophylla Care Tips

Light Requirements

To ensure the optimal growth and health of your Hoya macrophylla, it is important to provide it with the right amount of light. This plant thrives in indirect bright light, making an east-facing window an ideal spot. Avoid placing it in direct sunlight, as it can cause the leaves to scorch. If you don’t have an east-facing window, a south-facing window can work as well, but take precautions to prevent prolonged exposure to direct sunlight. North-facing windows may not provide enough light, while west-facing windows can be too intense and lead to leaf burn. Aim for around 6-8 hours of bright, indirect light per day for your Hoya macrophylla to flourish.

Soil and Watering

Hoya macrophylla prefers well-draining soil to prevent waterlogged roots. You can use a potting mix specifically designed for Hoyas or create your own mix by combining perlite, orchid mix, and crushed eggshells for added calcium. The crushed eggshells can help maintain a slightly alkaline soil pH.

When it comes to watering your Hoya macrophylla, proper hydration is crucial. Make sure the soil dries out completely between waterings to prevent root rot. A good watering technique is the “deep watering” method. Submerge the pot in water for 10-15 minutes and allow excess water to drain. Avoid using tap water, as Hoyas are sensitive to chemicals. Instead, opt for distilled or rainwater. During winter, when the plant is in its dormant phase, reduce watering to avoid overhydration.

Temperature and Humidity

Hoya macrophylla thrives in warm and humid conditions, mimicking its native tropical rainforest habitat. Ideally, maintain temperatures above 55 degrees Fahrenheit to prevent dormancy and promote growth. In higher temperatures, between 60-85 degrees Fahrenheit, the plant will flourish. Be cautious of drafts and direct air from heating or cooling vents, as they can negatively impact the plant.

To satisfy its humidity needs, mist your Hoya macrophylla regularly or place it in a naturally humid environment like a bathroom. If the humidity is low in your home, you can use a humidifier or create humidity by placing the plant on a tray filled with pebbles and water. Aim for humidity levels above 40% for optimal growth and health.


Fertilizing your Hoya macrophylla during its active growing season can promote healthy leaf growth and potential flowering. Use a half-strength orchid fertilizer or organic fish emulsion once a month. Diluting the fertilizer is especially important for Hoyas, as they are sensitive to high concentrations of nutrients. During the plant’s dormant period, typically during winter, refrain from fertilizing to prevent overfeeding and potential damage to the plant.

Pruning and Propagation

Minimal pruning is required for Hoya macrophylla. Remove any unhealthy or dead stems and leaves to maintain the plant’s appearance and overall health. You can propagate Hoya macrophylla through herbaceous stem cuttings in water or long-fiber sphagnum moss. Select healthy stems that are around 5 inches long and have at least two leaves. Dip the cut end of the stem in rooting hormone to stimulate root growth. Plant the stem in moist sphagnum moss, burying the nodes (points where leaves emerge) in the moss. Provide indirect bright light and keep the moss evenly moist until roots are established, which typically takes around 40 days.

Common Issues and Pests

Like any plant, Hoya macrophylla is susceptible to certain issues and pests. Overwatering can lead to yellowing leaves, while excessive sunlight can cause brown tips. Fluctuations in watering and temperature may result in curling leaves. Proper care and attention to watering and light conditions can help mitigate these issues.

Common pests that can infest Hoya macrophylla include mealybugs, aphids, and spider mites. Regularly inspect your plant for signs of pest infestation, such as sticky residue, webbing, or visible pests on the leaves. If detected, use rubbing alcohol-soaked cotton swabs to physically remove mealybugs or treat with insecticidal soap. Neem oil can also be effective against pests. Be sure to follow the product’s instructions and test a small area before applying it to the entire plant.


Hoya macrophylla, also known as the Wax Plant, is a stunning houseplant that can thrive with proper care and attention. By providing adequate light, well-draining soil, appropriate watering, ideal temperature and humidity levels, and regular fertilization, you can enjoy the beauty of Hoya macrophylla in your home. Remember to prune the plant minimally and propagate it through stem cuttings when desired. Stay vigilant against common issues and pests and address them promptly to keep your Hoya macrophylla healthy and vibrant. With a little love and care, your Hoya macrophylla will reward you with its breathtaking foliage and occasional clusters of delicate flowers.
