In addition to being relatively easy to take care of, the Hoya Obovata makes a splendid hanging plant with its long tendrils that easily climb moss poles and trellises. Since drought-tolerant, this tropical plant can last forever and mature into very big plants.

While they are mostly not grown for their flowers, they produce beautiful flowers with a pleasant fragrance. The most important care for your Hoya plant is proper fertilization. This is because they are naturally fast-growing foliage cultivars that greatly benefit from regular fertilization, especially during summer and spring. According to Thespruce, below are some of the factors that need to be considered when growing your Hoya Obovata plant:
1. Bright Light
The Hoya Obovata plant requires bright light to grow successfully. They usually grow up among trees where they can receive bright light in their natural habitat. When grown outdoors, prevent exposure to direct rays of the sun and when cultivated indoors, place it at a south-facing window or any very bright location. Experts also recommend placing the plant in half-day direct sun at a west or east window location.
2. Well-drained Soil
Hoya Obovata plant thrives well in aerated, well-drained soils. This is because their roots require good drainage and air circulation. Their soil composition should include perlite, orchid bark, and peat to provide adequate room for the plants’ roots. You can also use a mix of pumice, orchid bark, compost, and potting soil.
3. Moderate Temperature and Humidity
Since they are semi-succulent epiphytic plants, Hoya Obovatas grow well in areas with regular misting or high humidity levels. The humidity level should be kept at about 60 percent and in temperatures ranging between 15° C to 29° C. However, during winter, you will need to change the temperature and humidity levels. Avoid placing your Hoya plant too close to heat vents, drafty windows, and fans to prevent exposure to extreme temperatures. Alternatively, you can decide to cluster other household plants with the Hoya Obovata or use a humidifier.
The Hoya Obovata plant does not grow well with frequent watering and thus should be allowed to dry out between watering intervals thoroughly. The rate of watering is highly dependent on various factors such as the type of pot (ceramic, terracotta, plastic), planting season, amount of light it receives, and the potting mixture. It is often advisable to cut down on the amount of water while the plant is dormant, usually in the winter and fall months.
5. Regular Fertilization
Hoya Obovatas are fast-growing tropical plants that usually require regular fertilization during the summer and spring to ensure healthy growth. Once your Hoya plant is about to flower, use a high phosphorus fertilizer to encourage vigorous flowering. Your Hoya Obovata plant should be fertilized at least twice a month during the summer and spring seasons.
Propagating Hoya Obovata

Select a healthy stem with two to three leaves on it and cut it to about 4-5 inches long. After, add a powdered or liquid-based rooting fertilizer to the stem in the pot. It is advisable to regularly water the potting soil, but do not overwater it. Place the pot or container with a cutting in an area where it will receive indirect bright sunlight. This area should also be humid, to allow roots and shoots to fully mature, which can take several weeks.
