When to repot

Hoya finlaysonii

Hoya epc 317 is a young plant, so you probably won’t need to repot it until early spring. This species grows in warm, humid areas of Thailand and Malaysia, so it should be exposed to high humidity when growing indoors.

Mist your plant frequently and place it on a tray with pebbles that you fill with water once a week. Repot into an 8-inch pot filled with soil designed for cacti and succulents. Allow only one root per hole; make sure each one is at least 2 inches long before planting.

Keep your hoya in bright light but out of direct sunlight, which can scorch its leaves. Water every two weeks if there isn’t enough humidity in your home. If you notice leaves turning yellow or falling off, move your plant to a more humid environment or mist it more often.

Dormancy/Winter rest

During dormancy, Hoya finlaysonii will be completely inactive. During dormancy, your plant should be kept in a well-lit area that is between 55 and 75 degrees Fahrenheit.

You should avoid moving or repotting your plant during winter rest. The soil can become hard as it dries out, so water sparingly. If you are keeping your plant indoors, you can use a humidifier to keep humidity levels high enough for healthy growth.

If you are growing outside, make sure to bring your plant inside before temperatures drop below freezing. Once temperatures rise above freezing again in springtime, move your hoya back outside and resume watering normally until it begins to grow again on its own.
