Light Requirements

Hoya carnosa tricolor prefers bright, indirect sunlight. Avoid placing the plant in direct sunlight, as this can scorch the leaves. If you notice that the foliage is turning yellow or brown, it may be receiving too much direct sunlight.


When it comes to watering Hoya carnosa tricolor, it’s important to strike a balance. Overwatering can lead to root rot, while underwatering can cause the plant to dry out and die.

Water your plant when the top inch of soil feels dry to the touch. Water thoroughly, allowing the excess water to drain out of the bottom of the pot. Empty the saucer beneath the pot to prevent the roots from sitting in water.


Hoya carnosa tricolor prefers moderate to high humidity levels. You can increase the humidity around your plant by placing a humidifier nearby or grouping it with other plants. Another option is to mist the foliage regularly with a spray bottle.


Hoya carnosa tricolor prefers temperatures between 60-80°F (16-27°C). Avoid placing the plant in areas with drafts, such as near doors or windows.


Hoya carnosa tricolor prefers well-draining soil that is rich in organic matter. You can use a mixture of peat moss, perlite, and vermiculite to create a suitable soil mix.


Hoya carnosa tricolor doesn’t require frequent fertilization, but you can feed it with a balanced houseplant fertilizer every month during the growing season (spring and summer). Avoid fertilizing during the fall and winter when the plant is dormant.


Hoya carnosa tricolor doesn’t require frequent pruning, but you can trim back any dead or yellowing leaves as needed. You can also pinch back the stems to encourage bushier growth.


Hoya carnosa tricolor is relatively easy to propagate through stem cuttings. Simply take a cutting that includes one or two nodes, remove the bottom leaves, and place it in a pot filled with moist soil. Keep the cutting in bright, indirect sunlight and water it regularly until it begins to produce new growth.

Common Pests and Problems

Hoya carnosa tricolor is a relatively pest-resistant plant, but it can be susceptible to mealybugs and spider mites. These pests can be controlled with insecticidal soap or by wiping the foliage with a damp cloth.

If you notice that the leaves are turning yellow, this may be a sign of overwatering or underwatering. Adjust your watering schedule accordingly and check the soil moisture levels regularly.
