Are you looking for a unique and beautiful house plant to add to your indoor garden? Look no further than the Hoya serpens, also known as the Wax-flower Plant. This tropical plant is known for its trailing vines, beautiful leaves, and delicate pale green flowers with a sweet fragrance. In this article, we will explore all the essential care instructions and propagation methods for the Hoya serpens, so you can enjoy the beauty of this plant in your own home.


The Hoya serpens thrives in bright dappled sunlight. It should be placed in an area with filtered and indirect sunlight, away from direct ultraviolet rays. This plant’s ideal location is near a window with sheer curtains or in a spot where it receives 4-6 hours of indirect sunlight per day. Providing the right lighting conditions will ensure healthy growth and blooming of the Hoya serpens.


Proper watering is crucial for the Hoya serpens. It prefers to be watered every other day, allowing the soil to dry out partially between waterings. Overwatering should be avoided, as it can lead to root rot. Before watering again, check the moisture level of the soil by sticking your finger about an inch deep into the soil. If it feels dry, it’s time to water. Strike a balance to keep the soil slightly damp but not soggy.


Hoya serpens enjoys high humidity levels. Moderate to high humidity, ranging from 60% to 100%, is ideal for its growth. If the humidity in your home is low, you can increase it by placing the plant on a tray with water and pebbles or by using a humidifier. Regular misting of the plant’s leaves can also create a more humid environment, mimicking its natural habitat.


Well-draining soil mixtures are recommended for this plant. Hoya serpens prefers a coarse and well-draining soil mixture with a pH level of 6.0 to 7.0. It is best to use a potting mix specifically formulated for tropical plants or create your own mixture by combining peat moss, perlite, and orchid mix. This combination will ensure that excess water flows freely and nutrients are properly absorbed by the roots.


The Hoya serpens can tolerate a wide range of temperatures. It prefers cool to moderate temperatures ranging from 60 to 86 degrees Fahrenheit (15-30 degrees Celsius). Avoid exposing the plant to extreme temperatures and cold drafts, as it can be detrimental to its overall health. Keep it away from air conditioners, heaters, or direct airflow from fans to prevent temperature stress.


To promote healthy growth and blooming, the Hoya serpens can be fertilized with a well-balanced fertilizer slightly higher in phosphorous. Regular fertilization is recommended, especially during the spring and summer months when the plant is actively growing. Follow the instructions on the fertilizer packaging for dosage and frequency. Be cautious not to over-fertilize, as it can cause root burn.


The Hoya serpens should be repotted every two years or as needed to ensure its healthy growth. When repotting, choose a pot that is slightly larger than its current one to provide room for root expansion. Use a well-draining potting mix with the appropriate nutrients. Gently loosen the roots during repotting to avoid damaging them. Repotting will rejuvenate the plant and provide it with fresh soil and nutrients.


Pruning is an essential aspect of Hoya serpens care. It may be necessary to control the size of the plant and maintain its pleasant appearance. Regular pruning helps remove any dead or yellow leaves, promotes new growth, and prevents the plant from becoming leggy. Be sure to use clean and sterile pruning tools to prevent the spread of diseases.


The Hoya serpens can be propagated through stem cuttings. To propagate, select a healthy stem with two to three nodes. Cut the stem just below a node using clean and sterilized pruners. Let the cut end callus over for a few days before planting it in a well-draining potting mix. Water the cutting lightly and keep it in a warm and humid environment. New roots should start forming within a few weeks, at which point you can treat it as a mature plant.

Growth Rate

Hoya serpens is known for its relatively rapid growth rate. With optimal conditions and care, it can reach a height of 8-10 feet (2.4-3 meters). However, keep in mind that it can take several years for the plant to reach its full potential. Patience is key when growing the Hoya serpens, as it can take 5 to 7 years for the plant to fully mature and produce its unique pale green flowers.


When fully mature, the Hoya serpens blooms with clusters of pale green flowers that have a sweet fragrance. The blooming period can vary, but it typically occurs in the warmer months. The exquisite flowers are a sight to behold and will add a touch of elegance and beauty to any indoor space.

Common Problems

Like any other house plant, the Hoya serpens can face a few common problems. Pests such as mealybugs and aphids can infest the plant. Regularly inspect the plant for any signs of pests and treat them promptly with organic insecticides or neem oil. Stunted growth can indicate issues with watering, either overwatering or underwatering. Make sure to strike a good balance and adjust watering accordingly. Sooty mold can occur due to nectar production, so it’s important to monitor the plant for any signs of mold and take action if necessary.

In conclusion, the Hoya serpens is a tropical plant that requires bright dappled sunlight, average watering, high humidity levels, well-draining soil, and slightly acidic soil conditions. It prefers cool to moderate temperatures and can be fertilized regularly. Pruning, repotting, and propagation are also important aspects of care. The plant blooms when mature, with pale green flowers and a sweet fragrance. Care should be taken to prevent common problems such as pests, stunted growth, and sooty mold.
