Why Lava Rocks for Planters is Necessary
When I first started my gardening journey, I was on the lookout for materials that could enhance my planting experience. That’s when I discovered lava rocks, and I quickly realized how essential they are for my planters. One of the primary reasons I love using lava rocks is their ability to improve drainage.

Moreover, lava rocks are incredibly lightweight and easy to handle, which has made my gardening tasks much more manageable. I appreciate that they don’t compact over time, maintaining their structure and aeration properties. This ensures that my plants receive the necessary oxygen for healthy growth.
