Light Requirements

The Hoya obovata prefers bright, indirect light, but can tolerate some direct sunlight. The best window direction for this plant is east- or west-facing, as it provides gentle, indirect light. If you are placing the plant in a south-facing window, make sure to provide some shade, such as a sheer curtain, to prevent scorching. The ideal light intensity for the Hoya obovata is between 200-400 foot-candles. Signs of too much light include yellowing or scorching of the leaves, while signs of too little light include weak and spindly growth.

Watering

To water your Hoya obovata, start by checking the soil moisture. Stick your finger into the soil up to the first knuckle, and if the soil feels dry, it's time to water. Water the plant thoroughly, making sure the pot drains well to prevent waterlogged soil. The frequency of watering will depend on the time of year and the humidity of your environment. In the summer months, water the plant every 7-10 days, while in the winter months, water every 14 days. Make sure to use room-temperature water, as cold water can shock the roots. Signs of over-watering include yellowing or droopy leaves, while signs of under-watering include wrinkled or crispy leaves.

Soil and Potting

The Hoya obovata prefers a well-draining potting mix that is rich in organic matter. A good soil mix recipe is 2 parts peat, 1 part perlite, and 1 part orchid bark. This mix will provide the plant with good drainage and aeration, while also retaining some moisture. The plant prefers to be slightly root-bound, so choose a pot that is only slightly larger than the plant's root system. Repot the plant every 2-3 years in the spring, when it becomes pot-bound. Signs that the plant needs to be repotted include roots growing out of the drainage holes or the plant becoming top-heavy.

Fertilizing

The Hoya obovata is a light feeder and requires minimal fertilization. Feed the plant with a balanced, water-soluble fertilizer (20-20-20) during the growing season (spring and summer). Dilute the fertilizer to half the recommended strength to prevent burning the roots. Fertilize the plant every 2-3 weeks, making sure to skip fertilization during the winter months when the plant is dormant.

Humidity and Temperature

The Hoya obovata prefers a humid environment, with a relative humidity of 50-60%. To achieve this, you can place the plant on a tray filled with water and pebbles, or use a humidifier. The plant also prefers a consistent temperature between 65-80°F (18-27°C). Avoid placing the plant near heating or cooling vents, fireplaces, or drafty windows. Some other tips for achieving the right humidity include grouping plants together, using a cloche or terrarium, or placing the plant in a bathroom or kitchen where the humidity is naturally higher.
