5 Reasons Why Aloe Leaves Curl (And How To Fix It)

Aloe plants are pretty tough and can handle tough weather, but they can still run into problems. Today, I’ll share one of these issues with you.

If your aloe’s leaves are curling, it might be because of too much or too little light, or changes in temperature. Watering the wrong way or having bad drainage can also make leaves curl. To fix this, you might need to change how you water it. Keeping the right balance of nutrients and keeping pests away are important for stopping and fixing leaf curling.

1. Drought Stress

Usually, when aloe leaves curl inwards, it’s because they’re not getting enough water. This often happens because people think aloes don’t need much water.

Here’s a fix:

  1. Give your aloe plant plenty of water so that the soil gets wet all the way to the bottom of the pot. Make sure any extra water can drain out.
  2. Keep an eye on how moist the soil is. Don’t let your aloe sit in dry soil for too long.
  3. Wait for the soil to almost completely dry out before you water the plant again.

2. Too Much Sun

If your aloe leaves are curling up, it might be because they’re getting too much sun. Aloe plants can get hurt by too much UV light, causing the leaves to curl as the plant tries to protect itself.

Hot winds can make this even worse. For instance, if your aloe is outdoors and there’s a warm wind on a sunny day, the leaves might get sunburned. They’ll curl inward and change color, turning pale and then yellow.

Here’s a fix:

  1. Move your aloe to a spot where it gets less sun.
  2. It’s ideal if the plant gets about 6 hours of direct sunlight, and then bright but indirect light for the rest of the day.

3. Root Rot

Root rot is a big issue when growing plants, including aloe. It often happens because of overwatering, which leaves the roots in water for too long. This cuts off oxygen, making the plant struggle. Root rot also thrives in damp conditions.

Signs of root rot include the aloe’s leaves curling outward (downward) and possibly turning yellow. You might also smell something bad coming from the pot.

Here’s a fix:

  1. First, take your aloe out of its pot and remove all the soil from the roots.
  2. Cut off any dead roots and clean the cuts with hydrogen peroxide.
  3. Let the plant dry in the shade for a few hours.
  4. Then, replant the aloe in soil that drains well.
  5. Choose a pot with lots of holes for drainage.
  6. Put the pot in a shady spot. Once you see new leaves growing and the plant looks healthy, you can slowly get it used to sunlight again.
  7. Water the aloe only when the soil is almost completely dry.

4. Temperature Stress

If there’s a sudden drop in temperature, aloe plants might curl their leaves. This is common for aloes grown outside. In summer, the days can be hot and sunny, but the temperature might drop below 50°F (10°C) at night. This big change can make the leaves curl and turn red.

Here’s a fix:

  1. Make sure your aloe isn’t near devices that make it too hot or too cold.
  2. Keep an eye on the weather forecast. If it’s going to be cold, bring your aloe inside.
  3. Water the plant one more time.

5. Diseases

Succulents, like aloe, which store a lot of water in their leaves, can be prone to fungal diseases. If your aloe gets infected, you might see not just deformed leaves, but also brown spots or mold.

Here’s a fix:

  1. First, check your plant for any damaged parts and cut off any rotten areas.
  2. Then, spray the aloe with a fungicide to treat the infection.
  3. Remember to water your aloe just enough, not too much.

Conclusion

In conclusion, caring for aloe plants involves being mindful of various factors like watering, sunlight exposure, temperature changes, and the risk of fungal diseases. While these plants are generally hardy, they can face issues such as leaf curling, discoloration, and root rot due to environmental stressors or improper care.

By understanding these challenges and implementing the solutions discussed – like adjusting watering habits, relocating the plant to suitable light conditions, and treating with fungicides when necessary – you can ensure your aloe remains healthy and thrives. Regular observation and prompt action are key to keeping your aloe plant in good shape.

Thank you for this article.

I had finally gotten a chance to change the soil of my aloe vera plant and was looking for some guidance on how to address some of the issues I had had with the plant since moving to a place with no direct sunlight...only 2 windows, front and back (a disadvantage of townhomes in the middle :-( )

It was very helpful in informing me on how to water my plant and why the leaves were curling and why the newer leaves were spotted.
