Overwatering
One of the main reasons why succulent leaves turn brown is overwatering. Succulents are known for their ability to store water in their leaves, stems, or roots, allowing them to thrive in arid conditions. However, if they receive too much water, their leaves can become waterlogged and develop brown spots or turn completely brown.
Overwatering can lead to root rot, which occurs when the roots are unable to receive enough oxygen due to excessive moisture. As a result, the roots may become mushy and begin to decay. This can cause the succulent to wilt, and its leaves may turn brown as a result.
Underwatering
While succulents are adapted to withstand drought conditions, underwatering can also cause their leaves to turn brown. When succulents don’t receive enough water, they may start to wilt and become dehydrated. This can lead to the browning and drying out of the leaves.
Underwatering can also cause the plant to enter a state of dormancy, where it conserves energy by shriveling up its leaves. This can result in the leaves turning brown as they lose moisture.
Sunburn
Succulents thrive in bright light and are known for their ability to tolerate intense sunlight. However, direct exposure to prolonged or intense sunlight can cause their leaves to develop brown patches or turn completely brown. This is known as sunburn.
When succulents are exposed to excessive sunlight, their leaves can become damaged and unable to photosynthesize effectively. This can lead to the browning of the leaves as they die off.
Poor Drainage
Succulents require well-draining soil to prevent water from sitting in their roots for extended periods. If the soil used for potting the succulent does not have good drainage, water can accumulate around the roots, leading to root rot and the browning of the leaves.
It’s important to use a well-draining soil mixture specifically designed for succulents or cacti. This type of soil typically consists of a blend of coarse sand, perlite, or pumice, which allows excess water to flow through and prevents it from becoming trapped around the roots.
Pests and Diseases
Succulents can also develop brown leaves as a result of pest infestations or disease. Common pests that can damage succulents include mealybugs, aphids, and spider mites. These pests can cause the leaves to develop brown spots or turn brown due to their feeding habits.
In addition to pests, succulents can also be susceptible to fungal or bacterial infections, which can cause the leaves to become discolored and turn brown. It’s important to regularly inspect your succulents for signs of pests or diseases and take appropriate measures to control and prevent infestations.
