Common Pests and Diseases to Watch Out for When Propagating Hoya Compacta

When propagating Hoya Compacta, it is important to be aware of the common pests and diseases that can affect this plant. By understanding these potential issues and taking preventative measures, you can ensure the health and success of your Hoya Compacta propagation efforts. In this article, we will explore the various pests and diseases that may arise during the propagation process and provide tips on how to effectively manage and prevent them.

Common Pests

Spider Mites

Spider mites are tiny pests that can cause significant damage to Hoya Compacta plants. They suck the sap from the leaves, causing them to turn yellow and eventually fall off. To prevent spider mite infestations, regularly check the undersides of the leaves for any signs of webbing or tiny insects. If detected, treat the plant with an insecticidal soap or neem oil spray.


Mealybugs are another common pest that can attack Hoya Compacta plants. These small, white, cottony insects feed on the plant’s sap, causing leaves to turn yellow and curl. To get rid of mealybugs, gently wipe them off with a cotton swab dipped in rubbing alcohol. It’s also important to isolate any infected plants to prevent the spread of the infestation.


Aphids are soft-bodied insects that can quickly multiply and infest Hoya Compacta plants. They feed on the plant’s sap, causing leaves to become distorted and yellow. To control aphids, spray the plant with a strong stream of water to dislodge the insects. You can also introduce natural predators like ladybugs to help keep the aphid population in check.

Common Diseases

Root Rot

Root rot is a common issue that can affect Hoya Compacta plants, especially when overwatered. This fungal disease thrives in damp conditions, causing the roots to rot and eventually leading to wilting and yellowing of the leaves. To prevent root rot, make sure to allow the soil to dry out between waterings and ensure proper drainage in the pot.

Powdery Mildew

Powdery mildew is another fungal disease that can impact Hoya Compacta plants. It appears as a white powdery substance on the leaves, stems, and flowers, hindering photosynthesis and stunting plant growth. To combat powdery mildew, increase air circulation around the plant, avoid overhead watering, and consider using a fungicidal spray if the problem persists.

Leaf Spot

Leaf spot is a bacterial or fungal disease that causes dark spots to form on the leaves of Hoya Compacta plants. This can lead to yellowing and premature dropping of the affected leaves. To prevent leaf spot, avoid overhead watering, remove and destroy infected leaves, and ensure proper spacing between plants to promote air circulation.


In conclusion, when propagating Hoya Compacta, it is important to be vigilant in monitoring for common pests and diseases that can affect the plant’s health. By regularly inspecting the plant for signs of infestation or infection, taking preventive measures, and promptly treating any issues that arise, gardeners can help ensure the successful propagation and growth of their Hoya Compacta plants. With proper care and attention, gardeners can enjoy the beauty of this unique and resilient plant for years to come.
