Azaleas are a popular shrub known for their beautiful blooms. However, sometimes their leaves will turn brown. There are several reasons why this may happen, including too much sun, too little water, or pests.
By understanding the cause, you can take steps to prevent it from happening again in the future.
Azaleas are one of the most popular shrubs in America, prized for their beautiful blooms. But sometimes, azalea leaves will start to turn brown, which can be alarming for gardeners. There are a few different reasons why this might happen.
One possibility is that the plant is suffering from drought stress. If the soil around your azalea is dry and crumbly, and the leaves are brown and withered, then it’s likely that the plant needs more water. Give it a good soak, making sure to water deeply so that the roots get plenty of moisture.
Another possibility is that your azalea is getting too much sun. Azaleas do best in dappled sunlight or partial shade, so if they’re in full sun all day long, they may start to experience leaf scorch, which will cause the edges of the leaves to turn brown. Move your azalea to a shadier spot and see if that helps.
If you suspect that your azalea has a fungus or bacterial infection, then you’ll need to take action quickly. These infections can spread quickly through an entire plant, so it’s important to treat them right away. You’ll need to remove any affected leaves and branches and dispose of them properly (do not compost them).
Then treat the plant with a fungicide or bactericide according to label directions.
Finally, keep in mind that some varieties of azaleas are more susceptible to leaf problems than others.

How to Revive a Dying Azalea
When it comes to reviving a dying azalea, there are a few different things you can do. First, check to see if the plant is getting enough water. If not, water it deeply and regularly.
Second, fertilize the plant with an acidic fertilizer. Third, prune off any dead or dying branches. Finally, make sure the plant is getting enough sunlight.
If it’s not, move it to a sunnier spot. With a little love and attention, your azalea will be back to its old self in no time!
Why are My Azalea Leaves Turning Yellow
Azaleas are one of the most popular shrubs in the landscape. They are prized for their beautiful flowers and lush foliage. However, sometimes azalea leaves will turn yellow.
This can be due to a number of reasons, including disease, pest infestation, or cultural problems.
One of the most common diseases that can cause yellowing leaves on azaleas is called chlorosis. Chlorosis is caused by a lack of iron in the soil.
Azaleas need iron to produce green chlorophyll pigment in their leaves. Without enough iron, the leaves will turn yellow. Chlorosis is usually more prevalent in alkaline soils with a pH above 7.0.
To correct this problem, you will need to apply an iron fertilizer to your azalea plants according to package directions.
Pest infestations can also cause azalea leaves to turn yellowish-green or even brown and dry up. The two most common culprits are aphids and scale insects.
These pests suck the sap out of plant tissue, causing the leaves to wilt and eventually die off if left unchecked.
Azalea Leaves Turning Brown Curling
If you have an azalea and its leaves are turning brown and curling, there are a few things that could be happening. It could be that the plant is not getting enough water, or it could be that the soil is too alkaline. Another possibility is that the plant is suffering from a fungal disease called powdery mildew.
If you think that your azalea isn’t getting enough water, try increasing the frequency of watering. If the soil is too alkaline, you can try adding some sulfur to it. If powdery mildew is the problem, you’ll need to treat it with a fungicide.
Why are My Encore Azalea Leaves Turning Brown
If your Encore azalea leaves are turning brown, it could be due to a number of reasons. Here are some possible causes:
1. Overwatering or Underwatering – If you’re watering your azalea too much or too little, this can cause the leaves to turn brown and die off.
Make sure you’re giving your plant the right amount of water each week, and check the soil before watering to see if it’s dry.
2. Pest Infestation – Azaleas can be susceptible to pests like aphids, scale, and mealybugs. These pests can suck the sap out of the leaves, causing them to turn brown and eventually die.
If you think your azalea has a pest problem, take a closer look at the leaves and stems for signs of insects or damage. You may also see sticky honeydew on the leaves if there are aphids present.
3. Disease – There are several diseases that can affect azaleas, such as powdery mildew or root rot.
These diseases can cause the leaves to turn brown and die off. If you suspect your plant has a disease, contact your local Cooperative Extension office for more information and treatment options.
4. Environmental Stress – Azaleas can also be affected by environmental stressors like too much sun or wind exposure.
This can cause the leaves to turn brown and dry out.
Potted Azalea Leaves Turning Brown
If you have an azalea in a pot, you may have noticed that the leaves are turning brown. There are several reasons why this may be happening, and fortunately, there are also some things you can do to fix the problem.
One reason your potted azalea’s leaves may be turning brown is because of a lack of humidity.
Azaleas prefer moist air, so if the air around your plant is too dry, the leaves will start to turn brown and drop off. To increase the humidity around your plant, try misting it with water daily or setting the pot on a tray of pebbles filled with water. You can also buy a humidifier specifically for plants.
Another reason for browning leaves could be over- or under-watering. If you’re not watering your azalea enough, obviously it will start to suffer. But even if you’re watering it regularly, you could still be doing it wrong.
Water should always be applied directly to the soil, not to the leaves or flowers. And make sure not to overwater – too much water can actually drown your plant! Let the top inch or so of soil dry out before watering again.
Finally, another possible cause of brown leaves is fertilizer burn. This happens when there’s too much fertilizer in the soil and it starts “burning” the roots of your plant. If you think this might be what’s happening, stop fertilizing immediately and flush out the excess fertilizer from the potting mix with plenty of water (outside!).
Once you’ve done that, resume fertilizing at half the recommended rate until things improve.

Should I Remove Brown Leaves from Azalea?
It’s a common question for those who have an azalea – should you remove the brown leaves? The answer is both yes and no. While it’s important to keep your azalea healthy by removing dead or dying leaves, you don’t necessarily need to remove every single brown leaf.
If there are only a few brown leaves, they can actually be beneficial for the plant. Brown leaves provide protection from the sun and wind, help retain moisture, and add nutrients back into the soil as they decompose.
Of course, if there are too many brown leaves or if the plant is otherwise unhealthy, removal may be necessary.
If you’re not sure whether to remove the brown leaves or not, it’s always best to consult with a professional.
How Often Should You Water Your Azaleas?
It is important to water your azaleas regularly to keep them healthy and hydrated. However, over-watering can be just as damaging as not watering enough. Azaleas need about 1 inch of water per week, either from rainfall or from irrigation.
If you live in an area with little rainfall, you will need to supplement with irrigation. Be sure to check the soil before watering to see if it is already moist. You can also insert a finger into the soil about 2 inches deep – if it feels dry then it’s time to water.
Why Does My Azalea Look Burnt?
When it comes to azaleas, it’s not uncommon for them to look a little bit “burnt.” This is usually due to one of two things: either the plant is getting too much sun, or the soil is too dry. If your azalea is in direct sunlight for more than six hours per day, it’s likely that the leaves are scorched from the heat.
To prevent this, try moving the plant to a shadier spot. If the soil around your azalea is dry and crumbly, that could also be causing the leaves to look burnt. Be sure to water deeply and regularly, especially during hot summer months.
How Do I Know If My Azalea is Dying?
If your azalea is dying, there are a few things you can look for to be sure. First, check the leaves for signs of discoloration or wilting. If they are brown or yellow, this is a sign that your plant is not healthy.
Also, check for any new growth on the plant. If there is no new growth, this could be another sign that your azalea is dying. Finally, check the roots of the plant.
If they are black or mushy, this is a sure sign that your azalea is not doing well and may be dying.
Q&A – Why have my azalea leaves lost their green color?
Conclusion
If you have an azalea and its leaves are turning brown, there could be several reasons. It could be because of the weather, pests, or disease. If the leaves are only turning brown on the edges, it’s probably due to too much sun or wind.
If they’re brown all over, it could be a pest problem or a disease called chlorosis. Chlorosis is caused by a lack of iron in the soil, which can be remedied by adding iron sulfate to the soil. If you think your azalea has a pest problem, you should inspect it for scale insects, aphids, or mites.
These can all be treated with insecticidal soap or horticultural oil.
