rocks vs 'lava' rocks
Comments (1)I'm personally not a big fan of lava rock in most situations - it kind of looks out of place. Other types of rock tend to look more natural.

If you use it as the sole ingredient you would undoubtedly have to water more than a traditional potting soil and be very careful with fertilization.
