Why Does My Aloe Vera Have Brown Spots?
Aloe leaves retain old injuries, so a dry fixed spot does not necessarily indicate ongoing disease. The urgent distinction is between stable firm tissue and enlarging soft areas near the leaf base.
Trace Spots to a Recent Light Change
Pale or brown areas on the exposed side after moving outdoors can be sun injury. That tissue will not regain its original appearance, but gradual acclimation can protect subsequent leaves. Avoid treating a fixed sun scar with pesticide simply because it is brown.
Spot Patterns to Watch
| Spot pattern | Possible cause | What to do |
|---|---|---|
| Dry tan patches | Sun stress | Move to brighter indirect light, then acclimate slowly |
| Dark soft spots | Overwatering or rot | Reduce watering and inspect roots |
| Scattered old scars | Minor damage | Monitor only |
| Spots after cold exposure | Cold injury | Keep plant warm and dry |
Review recent watering
Aloe leaves store water, so soggy soil is a bigger problem than slight dryness. Repeated overwatering can lead to stressed tissue and rot-like spotting.
Look at the light transition
Aloe can scorch if moved suddenly into intense direct sun. Gradual acclimation is much safer than a sudden jump.
Check firmness
Dry, firm spots are different from wet, soft spots. Soft damage deserves quicker action because it may spread.
Improve airflow and drainage
Use a fast-draining mix and a pot with drainage holes. Let the mix dry between waterings.
Isolate Expanding Wet Lesions
Soft, spreading damage combined with wet mix deserves prompt inspection of the base and roots. Keep affected tissue away from other plants while determining the cause. Clean cutting tools and preserve sound sections rather than leaving decaying material pressed against healthy leaves.
Inspect any new spots after a foliar spray and note whether they follow exposed droplet areas. Oil or soap products can injure sensitive foliage when misapplied, particularly under unsuitable heat or exposure. If pests are not confirmed, repeating a treatment on an already damaged aloe may create more marks. Compare newly formed leaves before deciding the problem is still active.
