15 Reasons Why Your Aloe Vera is Turning Brown and How to Fix Them

Sharing is caring!

The Aloe Vera plant – a stalwart houseplant beloved for its easy care and health benefits, but what happens when your typically verdant plant starts browning? Before you start panicking, understand that plants, like us, have their unique ways of communicating.

They do not do it through a flurry of text messages or a concerned voice mail but through visual cues. If your Aloe is turning brown, it’s sending you an SOS. And it’s time you learned its language to nurse it back to health.

Reasons Your Aloe Plant is Turning Brown

While Aloe Vera plants are generally resilient and hardy, they can get upset sometimes. Whether you’re an experienced plant whisperer or a green thumb newbie, your plant might be turning brown for a variety of reasons. Let’s decode the top causes and their remedies.

1. Overwatering: A Case of Too Much Love

Contrary to what you might think, your Aloe Vera doesn’t enjoy frequent swims. It’s a desert plant and thrives in dry conditions.

Overwatering could be the culprit behind your plant’s brown and mushy appearance. Ensure to water your Aloe only when the soil is completely dry, and remember, it’s better to underwater than to drown it in love.

2. Sunburn: Yes, Plants Can Get It Too!

Picture yourself on a beach without sunscreen, and you get the idea. Despite being a sun-lover, Aloe Vera can still get sunburnt if exposed to intense, direct sunlight.

Sunburnt plants will show signs of browning or bleaching. The remedy? Gradually introduce your plant to sunlight or provide it with filtered light to avoid the botanical equivalent of a painful sunburn.

3. Temperature Troubles: Not Too Hot, Not Too Cold

Aloe plants are not fans of extreme temperatures. Cold weather can cause the plant to freeze and turn brown, while very hot weather can dehydrate the plant.

The sweet spot for Aloe Vera is between 55 and 85°F. If the temperature spikes or dips, bring your Aloe indoors or move it to a cooler, shaded location.

4. Root Rot: The Silent Harmer

This is a common problem for many houseplants, and Aloe Vera is no exception. It is usually caused by overwatering or poor drainage, leading to brown, mushy roots and ultimately, a brown plant.

If you notice a foul smell or if the plant feels loose, it might be root rot. Salvage healthy parts of the plant and repot them in fresh, well-draining soil. Prevention, however, is the best cure.

5. Improper Potting: Don’t Skimp on the Homefront

Using the wrong type of soil or a pot without proper drainage could be stressing out your plant. Aloe Vera prefers sandy, well-draining soil and pots with good drainage. Upgrading your plant’s living conditions can turn that brown upside down.

6. Pests: The Uninvited Guests

Tiny pests such as mealybugs, aphids, or spider mites can cause your Aloe to turn brown. These pesky bugs suck the life out of your plant, causing it to discolor. If you spot these troublemakers, use an insecticidal soap or neem oil to evict them ASAP.

7. Poor Nutrition: Food For Thought

Plants, like humans, need a balanced diet. If your Aloe Vera plant’s leaves are turning brown, it could be due to a lack of essential nutrients.

While Aloe doesn’t need frequent feeding, an occasional dose of a balanced, water-soluble fertilizer during growing season can keep it happy. Remember, moderation is key. Over-fertilization can cause more harm than good.

8. Lack of Space: The Tight Squeeze

If your Aloe plant is turning brown and looking a bit cramped, it may be time for a new home. A pot that’s too small can constrict the plant’s roots, leading to stress and browning.

Repotting your Aloe Vera into a slightly larger pot can give it the room it needs to thrive. Don’t go overboard with the size though. A pot too large can lead to excess moisture and potential root rot.

9. Disease: Time to Call the Plant Doctor

While rare, diseases can cause your Aloe to turn brown. Fungal infections, such as Aloe rust, can result in brown spots on the leaves.

If you suspect disease, isolate your plant from others to prevent spread, remove affected parts, and apply an appropriate fungicide. When in doubt, consulting a plant health specialist can be invaluable.

10. Salt Buildup: A Salty Situation

Using tap water to water your plant can result in a buildup of salts in the soil, which can harm your Aloe. If you notice a white crust on the soil or pot edges, it might be salt buildup.

Flushing the soil with distilled or rainwater can help. In the future, try to use filtered, distilled, or rainwater for your Aloe Vera.

11. Overexposure to Wind: It’s a Breeze… or Is It?

Believe it or not, your Aloe Vera could be turning brown due to overexposure to wind. Winds, especially strong, dry ones, can stress your plant causing it to brown.

If you notice your plant struggling in windy conditions, relocate it to a more sheltered spot. It’s time to break the wind, not the plant!

12. Transplant Shock: New Home Blues

When you move a plant to a new pot or location, it can experience “transplant shock,” resulting in browning.

To avoid this, ensure you’re careful during the repotting process, handle the roots gently, and give the plant time to adjust to its new environment. Remember, change is hard, even for plants!

13. Fluctuating Humidity: The Moisture Mystery

Aloe plants prefer relatively low humidity. A sudden increase in humidity can cause the plant to turn brown. This can happen if you move your plant from a dry indoor area to a damp outdoor area.

To avoid this, try to keep the humidity level around your plant stable. As a bonus, you’ll also prevent the outbreak of fungus gnats.

14. Incorrect pH: The Acid Test

The pH of the soil can significantly affect your Aloe plant. If the pH is too high (alkaline) or too low (acidic), the plant may not absorb nutrients effectively, leading to brown tips.

Aloe Vera prefers slightly acidic to neutral pH. You can test your soil and adjust the pH with suitable amendments if necessary.

15. Inadequate Light: Seeking the Sunshine

While Aloe Vera plants can tolerate low light, they won’t thrive in these conditions. If your Aloe is brown and etiolated (elongated and weak), it might be craving more light. A sunny window ledge would be ideal, but be mindful of direct sun and avoid the scorching midday sun.

Understanding these common causes will help you troubleshoot your browning Aloe effectively. Now, it’s time to take action and bring back your plant’s vibrant green glory.

How to Revive Your Aloe Vera Plant

You’ve done the detective work, and now it’s time for some plant first aid. Here are some general steps to help revive your Aloe.

Assess the Damage:

A good first step in rescuing your Aloe is to assess the damage. Determine the affected areas – is it just the leaves, or does the problem extend to the roots? This will guide your next steps.

Prune the Affected Parts:

If only certain leaves are affected, you can prune these to prevent the issue from spreading. Use a clean, sharp tool to avoid infecting the plant.

Check the Roots:

If the browning is extensive, you might want to check the roots. Root rot can be a serious issue, and it’s often better to start fresh with any unaffected offshoots or leaves.

Correct Care Issues:

Depending on your earlier detective work, it might be time to correct any care issues. This could mean watering less, repotting in a pot with better drainage, or moving your plant to a location with more appropriate sunlight.

Monitor the Plant:

After you’ve made these changes, it’s crucial to monitor your plant closely. If your Aloe starts to green up again, you’ll know you’ve done well.

Remember, every plant owner faces challenges at times. Do not be disheartened. The key is to be patient, pay attention to the signals your Aloe is sending, and learn from the experience.

A browning Aloe Vera can feel like a plant owner’s worst nightmare. However, as we’ve explored, it’s often a case of some simple environmental factors gone awry. The key is to remain vigilant and responsive to your plant’s needs.

With the right care, your Aloe can bounce back to its healthy, green self. Remember, even the greenest thumbs encounter a brown leaf now and again. It’s all part of the rewarding journey of plant parenthood.
