Before we jump into the reasons why your succulent is turning black, let's first understand the anatomy of a succulent. Succulents are fleshy plants that retain water in their leaves, stem, or roots. They have adapted to harsh environments with minimal rainfall and high temperatures by storing water, so they can survive long periods without water.

Overwatering and underwatering can also lead to various problems, including black leaves. Now let's dive into the causes of succulent leaves turning black.

Sunburn

Sometimes, a succulent's leaves may turn black due to natural physiological changes. As the plant grows, older leaves may die off and turn black. This process is normal and nothing to worry about.
