Rocks on Top Of Soil Indoor Plants

As an indoor plant enthusiast, you're likely always on the lookout for ways to optimize your plants' growth and health. One popular trend that has sparked debate among plant enthusiasts is the use of rocks on top of soil in indoor plants. In this article, we'll delve into the world of rocks on top of soil, exploring the benefits, drawbacks, and everything in between.

What is the Purpose of Rocks on Top of Soil?

The primary purpose of placing rocks on top of soil is to improve drainage and prevent waterlogged soil. When water is poured into the pot, it flows through the rocks and into the soil, reducing the risk of overwatering. This is especially beneficial for plants that are prone to root rot, such as ferns and peace lilies. By allowing excess water to drain quickly, rocks on top of soil help to prevent root decay and promote healthy root growth.

Benefits of Using Rocks on Top of Soil

Beyond improved drainage, there are several other benefits to using rocks on top of soil. These include:

- Aesthetics: Rocks can add a decorative touch to your indoor plants, creating a visually appealing contrast between the soil and the pot.

- Temperature Regulation: Rocks can help to regulate soil temperature, keeping it cooler in the summer and warmer in the winter.
