Aloe Plant Turning Brown

Aloe plants are treasured for their succulent leaves and healing gel. But those leaves turning brown can alarm any gardener. Don’t panic – brown aloe leaves usually indicate simple environmental stress. With a few easy fixes, you can restore your aloe plant to vibrant health.

What Causes Brown Leaves on Aloe Plants?

An aloe with brown spots or shriveled leaves is crying out for better care. Here are the most common reasons behind stressed aloe plants:

Underwatering

As a succulent, aloe stores water primarily in its leaves. Without sufficient moisture, the leaves shrivel and turn brown, especially at the tips. Apply a deep watering immediately when the top 1-2 inches of soil become dry.

Overwatering

While aloe likes dry conditions, soggy soil causes major problems. Excess moisture prevents oxygen from reaching the roots, inviting root rot. With rotten roots unable to supply water, the leaves brown and mush out. Allow soil to thoroughly dry between waterings.

Sunburn

Aloe thrives on bright, direct light indoors and dappled outdoor sun. But too much intense sunlight scorches the leaves, causing unsightly brown patches. Filter the light with a sheer curtain or move the pot out of midday sun.

Cold Damage

If temperature drops below 50°F, aloe leaves turn brown and the plant declines. During winter, keep aloe in the warmest location in your home away from drafty windows and doors. Bring outdoor plants inside when frost threatens.

Chemical Burn

Harsh garden chemicals like fertilizers, pesticides, or herbicides that contact the leaves can cause brown spots or streaks. Always apply these products with great care, following label instructions.

Pests

Spider mites, mealybugs, and scale insects can infest aloe, sucking nutrients and moisture from the leaves. This causes small brown spots or lesions on the leaves. Immediately treat any infestations with horticultural oils or insecticidal soap sprays.

Poor Drainage

Aloe requires quick-draining soil and pots with drainage holes. Sitting in dense, soggy soil leads to root rot and brown, mushy leaves. Repot in a cactus/succulent potting mix or add perlite to improve drainage.

How to Treat Brown Leaves on Aloe ?

If your aloe plant has turned brown, take these restoration steps:

  • Clip off severely damaged leaves using sterilized garden shears. And remember don’t yank them off.
  • Check that the pot has drainage and the soil is a well-draining cactus/succulent mix.
  • Deeply water until the excess drains out the base. Allow soil to fully dry before repeating.
  • Move to a warm spot with proper light – bright indirect sun indoors or dappled shade outside.
  • Inspect closely for pests and treat any infestations. Isolate affected plants.
  • Remove spent lower leaves as they age so new leaves can take their place.
  • Wait patiently for recovery, which can take a few weeks or more.

Preventing Future Leaf Damage

Once restored, keep your aloe healthy by providing:

  • Deep watering only when soil partly dries out. Don’t overwater.
  • Quick-draining cactus/succulent soil mix and a pot with holes.
  • Bright, indirect sunlight inside. Dappled outdoor sunlight.
  • Warm temperatures, ideally between 70-80°F.
  • Occasional balanced fertilizer during spring through summer.
  • Pest monitoring and immediate organic treatment if discovered.
  • Removal of lower aged leaves to promote new growth.
  • Protection from frost and freezing weather.

Conclusion

With the right care, your aloe will reward you with plump, juicy leaves for years of growth. Just stay attentive to its light, water and temperature needs. A flourishing aloe plant can handle the occasional brown leaf or two.
