Aloe Leaves Turning Brown: What the Texture Tells You
Touch the affected leaf and check the center of the aloe. Firm reddish-brown coloring, a dry dead patch, and translucent mushy tissue need different responses. If the center or leaf bases are soft, inspect the roots before adding water.
This guide is for Aloe vera grown in a container.
Firm leaves with a bronze or reddish tint
An aloe can change pigment in strong light while its leaves remain intact. Sunnylands' Aloe vera fact sheet describes red coloring associated with intense sunlight. Color alone is not evidence that the leaf is rotten or dead.
Check whether the change followed a move into brighter light, and whether leaves are still firm and full. If the plant is in a new, intense sunbeam, give it some screening and watch the next growth. If it is also thin or wrinkled, check the root ball for drought. A bronze leaf does not automatically need either more water or less water.
A pale patch has become dry and brown
A dry, clearly defined patch on the exposed side after a sudden increase in sun fits scorch. Shield that exposure now. Once the plant is stable, introduce stronger light gradually. Keep a partly green, firm leaf; cutting away every scar removes useful tissue.
A dry tip on a thinning leaf can also follow drought. If the mix is dry throughout and the base is firm, water thoroughly and let the pot drain. If only one oldest outer leaf is drying while the center stays firm, the plant may be shedding that leaf. Remove it once it is dry and releases easily.
Aloe needs bright light and a root zone that dries between waterings. The RHS aloe guide describes its intolerance of continuously wet mix.
Translucent or mushy leaves
First check recent cold exposure. A cold trip, open window, or freezing glass can injure succulent tissue, leaving it water-soaked before it browns or collapses. Move the aloe into a sheltered, warm location. Freeze damage can occur even in dry soil; the University of Arizona's succulent guide covers this distinction from watering damage.
If the mix is wet, empty runoff and unpot when bases are soft, leaves detach easily, or the center is collapsing. Gently remove enough soil to inspect the roots and the short stem beneath the rosette.
The rosette base and some roots remain firm
Remove roots and leaves that are breaking down, using a clean blade and cleaning it between diseased cuts. Preserve firm attached roots. Repot the sound plant into fresh succulent mix in a drainage pot fitted to the remaining root system. The potting guide explains what a draining mix needs to do.
If cutting fleshy tissue was necessary, let the wound surface dry and seal before it contacts damp mix. Once sealed, water the rooted plant when the mix is dry; drain fully and let it dry again before the next watering.
The main base or center has rotted
Look for a separate, firm offset—a small rosette beside the parent—with sound roots of its own. Detach it from the rotten parent, preserve its roots, and pot it separately in clean mix. Illinois Extension describes rooted offsets as an aloe propagation method.
A detached piece of aloe leaf is not a reliable substitute for a healthy offset. If the entire base, center, and all offsets have broken down, discard the plant and old mix. Retaining mushy tissue in fresh soil will not rebuild the rosette.
