Aloe vera plants can develop problem leaves that appear brown, thin and curled. Though these dying aloe vera leaves indicate there is an issue with the plant, their presence usually doesn't mean the plant itself is dying. It's possible to grow aloe plants with dying leaves if you take steps to identify and address the reason the leaves are dying. This process is usually completed in a trial-by-error setting, but should eventually help you solve the problem.
Move the aloe vera plant into an area that gets partial sunlight if its leaves are flat rather than upright. Though full sunlight can damage the plant, lack of light can be equally as harmful.
Transfer the aloe vera plant out of the sunlight if the dying leaves are turning brown. The brown leaves do not necessarily need to be removed, but if you'd like to do so for cosmetic purposes just break them off at the base and dispose of them.
Water the plant more frequently if the dying aloe leaves appear limp, curled and thin. This means the plant has begun to use up its own inner moisture stores, which causes the plant to look deflated. Aloe vera plants' dirt should be soaked, but allowed to completely dry out between waterings. This may mean they need water once a week or so in the summer, but less often in the winter. Check the soil every couple of days to see if the plant needs water.
Water the plant less frequently if all the leaves look listless, brown or discolored. This can be a sign of root rot, which happens when the plant's shallow root system is sitting in standing water. The plant should already be planted in a pot with a large drainage hole at the bottom; transfer it to a new pot if it is not.
