Why Your Hoya Plant Has Spots on Its Leaves?

This little beauty is also known as the wax plant, and it's a real crowd-pleaser. With its thick, waxy leaves and delicate flowers, the Hoya is sure to catch the eye of anyone who enters the room.


But the best part? Hoya plants are incredibly low-maintenance. Thriving in bright, indirect sunlight, these plants require watering only once a week or even less frequently. Additionally, they make excellent air purifiers, ensuring you breathe in fresh, clean air all day.


Leaf Spots

Have you noticed spots on the leaves of your beloved Hoya plant? Spots on Hoya leaves are a common issue that many plant owners face, and can be caused by a variety of factors.



One possible cause of spots on Hoya leaves is a fungal or bacterial infection. Over-watering, poor drainage, or high humidity levels can create the perfect environment for these types of infections to thrive. Fungal infections can cause brown or black spots on the leaves, while bacterial infections can cause yellowing or browning. To prevent infections, it's important to make sure your Hoya has well-draining soil, avoid getting water on the leaves, and maintain optimal humidity levels. A soil water meter lets you know the moisture level of the soil and therefore prevents over-watering. 



Insect damage is another common culprit. Aphids and spider mites are two pests that can feed on the sap of the plant, causing discoloration and spotting. Spider mites are especially problematic as they are difficult to see with the naked eye. If you suspect insect damage, check the undersides of the leaves for signs of pests. To get rid of these pests, try using an insecticidal soap or neem oil.


Natural Patterning

If you've ruled out these two possibilities, it's possible that your Hoya is simply prone to developing spots on its leaves as it matures. Some Hoya varieties, such as the Hoya carnosa, naturally develop flecks and spots on their leaves as they age. This is usually nothing to worry about and won't harm the plant. In fact, some Hoya enthusiasts consider these spots to be a desirable characteristic of the plant!



If you observe that the spots on the leaves of your Hoya plant are accompanied by symptoms such as wilting or yellowing leaves, it could be an indication of a more severe issue. Seeking advice from a plant specialist or horticulturist would be the best option to diagnose and address the problem. Moreover, it's crucial to be aware that Hoya plants are prone to a variety of diseases, such as root rot and leaf spot, which can lead to spotting and other indications.



Ensuring your Hoya plant remains healthy and vibrant requires giving it the appropriate care and attention. This involves maintaining optimal levels of soil moisture, providing sufficient light (LED grow lights), and refraining from over-fertilising and over-watering. Additionally, regularly inspecting your plant for signs of pests or disease can help you catch and address issues early on.


Spotting on Hoya leaves can be caused by a range of factors, from infections to pests to natural genetic traits. By taking the appropriate steps to prevent infections and pests, you can keep your Hoya looking healthy and vibrant for years to come. Happy Hoya growing!
