FAQ's
How do I maintain a lava rock garden?
Lava rock gardens are relatively low-maintenance. Regular leaf blowing or raking keeps them clean, while occasional washing with a garden hose removes dust. The rocks don't decompose or need replacement, making them a long-lasting choice.
Can I grow plants in lava rock?
Yes, lava rock is excellent for plants due to its porous nature, which provides good drainage and aeration. It's particularly suitable for succulents, cacti, and other drought-resistant plants. The rocks also retain heat, benefiting warm-weather plants.
What size lava rocks should I use for my garden?
The size depends on your design purpose. Use 3/4 inch to 1-inch rocks for pathways and general ground cover, 2-4 inch rocks for borders and accent areas, and larger boulders for focal points or retaining walls.
Are lava rocks good for drainage?
Yes, lava rocks are excellent for drainage due to their porous nature and irregular shapes. They create air pockets that allow water to flow through easily, making them ideal for areas prone to water accumulation or for use in rain gardens.
