Short answer
Brown, crispy leaf tips on an Aloe vera are usually caused by inconsistent watering or a buildup of mineral salts from tap water. The most effective fix is to switch to distilled or rainwater and ensure you are soaking the soil thoroughly only when it has completely dried out.
Brown, crispy tips on Aloe vera are a very common occurrence for indoor growers and rarely indicate a fatal condition. While slightly unsightly, this symptom is usually a sign that your plant is struggling with environmental stressors rather than a systemic disease, and it can typically be reversed with minor adjustments to your care routine.
Aloe vera plants require a complete dry-out cycle to thrive; if the plant is left in bone-dry soil for too long, the roots begin to die back, leading to dehydration in the furthest parts of the leaves. Conversely, waiting too long between waterings causes the leaf tips to crisp as the plant pulls moisture from its extremities.
Check: Feel the soil down to two inches; if it is completely compacted and pulling away from the sides of the pot, the plant is likely severely dehydrated.
Fix: Establish a consistent schedule where you soak the soil completely every three weeks, ensuring excess water drains away from the pot.
Tap water often contains high levels of fluoride, chlorine, and salts that the Aloe cannot process efficiently. These minerals migrate to the leaf tips through transpiration and accumulate, eventually causing the cellular tissue to die and turn brown.
Check: Check the surface of the soil or the rim of the terracotta pot for a white, crusty residue.
Fix: Switch to using distilled water, filtered water, or captured rainwater for several months to flush the excess minerals from the potting medium.
While Aloes prefer low humidity, extremely dry indoor air combined with proximity to a heat vent can cause the moisture in the leaf tips to evaporate faster than the roots can replace it. This results in the characteristic dry, brittle texture at the very end of the leaf.
Check: Observe if the browning is more severe on leaves closest to a heater or window with high radiant heat.
Fix: Move the plant at least three feet away from direct heat sources and ensure it is not sitting in a drafty location.
When to worry
If the browning spreads to the base of the leaves or if the leaves themselves begin to soften and become mushy, this indicates root rot and requires immediate repotting into fresh, fast-draining soil.

Diagnose my Aloe VeraYes, you can trim the brown tips using sterilized scissors for aesthetic reasons. Cut just outside the healthy green tissue to avoid causing further stress to the leaf.
No; in fact, over-fertilizing is more likely to cause tip burn than a deficiency. Aloe plants are slow growers and rarely need supplemental feeding.
Usually, no. If the center of the plant is still firm and vibrant, your Aloe is likely healthy and just reacting to environmental conditions.
