Why does my azalea look rusty?
The rust on your azalea is likely caused by a fungus called rust brown spot. This fungus is most active in warm, humid weather and can cause the leaves of your azalea to turn brown and eventually fall off.

What does fungus look like on azaleas?
Fungus on azaleas can appear as white, powdery mildew on the tips of the leaves. It can also appear as black, sooty mold on the undersides of the leaves. In severe cases, the fungus can cause the leaves to yellow and drop off.
What does an over watered azalea look like?
Over watering an azalea can lead to a number of problems such as wilting, yellowing leaves, and stunted growth. If you believe you have over watered your azalea, take immediate action to correct the problem.
Begin by allowing the soil to dry out completely. Then, increase the amount of time between watering sessions and be sure to water only when the soil is dry to the touch. If possible, improve the drainage in the planting area by adding organic matter to the soil or planting in a raised bed.
Finally, make sure you are using a properly sized pot with drainage holes to prevent waterlogged roots.
What is the fertilizer for azaleas?
The fertilizer for azaleas is typically a 10-10-10 or similar analysis fertilizer. The first number is the nitrogen (N) content, the second number is the phosphorous (P) content, and the third number is the potassium (K) content.
How do you get rid of powdery mildew on azaleas?
To get rid of powdery mildew on azaleas, start by pruning away any affected leaves. Next, move the plant to a location that gets more sun and ventilation. If powdery mildew is still present, you can treat it with a fungicide.
What is growing on my azalea leaves?
One possibility is that it is a fungus. Fungi can appear as white, fuzzy growths on plant leaves, and they are often a sign of a plant that is not getting enough light. Another possibility is that the growth is caused by a pest, such as scale insects or aphids.
These pests can suck the sap out of plants, causing them to become weak and stressed. If you suspect that pests are the cause of the growth on your azalea leaves, you should inspect the plant carefully and look for signs of pests.
Finally, it is also possible that the growth is simply a normal part of the plant’s growth cycle. Some plants, such as azaleas, produce new growth in the form of small, fuzzy growths. This new growth will eventually harden and mature into leaves.
If you are not sure what is causing the growth on your azalea leaves, you should contact a professional horticulturist or plant doctor for help.
