These natural black lava rocks are a versatile choice for plant care, aquariums, landscaping, and a variety of indoor and outdoor applications. Made from 100% natural volcanic material, they contain trace minerals that can support healthy plant growth and feature a porous structure that promotes proper drainage and airflow.
The porous surface helps absorb excess water while retaining a small amount of moisture around plant roots, helping reduce the risk of root rot. Their natural, fade-resistant black color subtly changes in appearance when wet or dry, adding visual interest to any application.
Available in a 1/8″ to 1/4″, these lava rocks can be used as a potting soil amendment, top dressing for potted plants, aquarium media, fire pit media, garden landscaping, and DIY projects. When used around fire features, be sure the material remains dry.
