Why Does an Aloe Plant Turn Brown?

Direct Sunlight

• The most common cause of aloe leaves turning brown is exposure to direct sunlight. While aloe plants thrive outside, they require partial shade. Inside plants should receive adequate, yet indirect sunlight.

Water

• As with most plants, too little or too much water will cause aloe leaves to brown. In high moisture regions, cold temperatures and inside gardens, aloe plants do not require frequent watering--once or twice a month will do. In hotter regions, it is important to water the aloe plant once or twice a week to maintain a healthy moisture level. A general rule of thumb is to water the plant once the soil has gone completely dry. If the plant begins to shrivel that means it needs water and is using its own fluids to supply itself.

Transplanting

• When transplanting young aloe plants, their leaves may turn brown or gray as the roots seek water and adjust to their new conditions. In this case, water the plants after the initial planting, but do not water them again for another three weeks.
