Aglaonema plants are one of the most popular types of houseplants. They’re easy to take care of and they come in a variety of colors, shapes, and sizes. That’s why it’s so frustrating when your aglaonema starts to turn brown!
It can be difficult to determine why this is happening, but we have a few ideas about what might be going on with your plant.
Why Is My Aglaonema Turning Brown?
Your aglaonema plant is turning brown as a result of overwatering or leaf burn. Overwatered leaves tend to be wet and droop, whereas burnt leaves will be very dry and crispy.
I will now go more in-depth into these causes and what you can do to stop them from happening again in the future.
Brown Aglaonema Plant Leaves from Too Much Water
Aglaonema plants thrive when you give them just enough water throughout their soil to completely saturate it, but should never be left to sit in a pool of water.
The easiest solution to this problem would be to cut back on how much water you give your plant each week. Instead of watering every few days to keep the soil moist, err on the side of caution by waiting for the top inch of the soil to dry.
You can test the dryness of the soil by sticking your finger about an inch deep. If the soil is dry, it’s time to water! But if you feel moistness, then you should wait a little longer.
Alternatively, you can use a moisture meter, which is a device that helps you determine the exact amount of water needed. Using this tool will ensure that you don’t overwater or underwater your aglaonema and gives you a better idea as to whether it’s time for another watering session!
You should take action if root rot is already present. Start by removing all the soil and examining the roots. If rotten, prune the roots with a pair of sterilized scissors and be careful not to cut other areas of the plant.
Next, allow the plant to dry out, and then re-pot it into the fresh potting mix that drains well. Always make sure the pot you use has drainage holes at the bottom to allow water to escape.
Brown Aglaonema Plant Leaves from Too Much Sunlight
An aglaonema plant that’s been over-exposed to the sun will have burnt leaves. This is most likely due to the plant being exposed to direct rays from the sun. If this is the case, simply move your plant to a shadier area of the room.
If this is your problem, try adding more shading around your plant with blinds or curtains, and be sure they stay closed during peak sunlight hours! You can also place it closer towards a north-facing window where there isn’t as much direct exposure from the sun.
Doing this will reduce the amount of sunlight that your plant is exposed to and allow it to grow healthier. Be sure not to go overboard with it though – the plant needs some sunlight to survive!
Brown Aglaonema Plant FAQs
This isn’t the easiest plant to keep happy. As such, you might have a few questions about taking care of your plant. If that’s the case, we’ve got you covered with some frequently asked questions!
Will brown aglaonema leaves turn green again?
No, it is rare for brown leaves to turn green again. Instead, they tend to get browner and browner until they die. The good news is that new growth will be green if you follow the recommended care instructions.
Should I remove brown leaves from aglaonema plant?
Yes, prune all brown and dying leaves from the plant as soon as possible. This ensures that your aglaonema stays healthy and keeps its pretty, green color!
Will too much water cause aglaonema plant to turn brown?
Yes, too much water will cause the plant to turn brown. You should only water your aglaonema when the soil is dry and never leave it sitting in a pool of standing water for too long!
When I touch my aglaonema plant, it seems like there is moisture on it?
This generally means that the plant is living in a humid environment. It could simply be guttation, which is when excess water is excreted from the leaves. If this continues to be an issue, you should consider repotting your plant into a different pot that has better drainage and place it in a bright area of the room.
Why does my brown aglaonema have black spots?
This usually means your plant has leaf spot, which is a fungal infection. Use neem oil to treat it and be sure to clean up excess debris that might collect on the surface of your plant’s soil.
Will direct sun cause aglaonema leaves to turn brown?
Yes, it can cause leaf burn and turn your plant’s leaves brown. You should try to place the aglaonema in a location with indirect, or filtered light from the sun and make sure it doesn’t stay there too long!
If you follow these tips for taking care of your aglaonema plants, they will look as beautiful as ever. These tropical plants are an ideal addition to any space that needs some green color! Just be careful not to expose them to direct sunlight for too long or overwater them – those can both cause problems if left unchecked.
