Lava sand is crushed scoria, a reddish brown to black volcanic slag. It has a texture full of holes. Lava sand is the most popular rock material.

It can be used in potting soils and bed preparation for all landscaping and food crops. Finer textured material would be even better if it was easily available.

Question: Is there a good time to apply lava sand, or can it be spread at any time of the year? Can it be used on shrubs and flower beds, as well as trees? What's the recommended amount to use? Is all lava sand the same? C.N., Dallas
Answer: Put lava sand out any time at a rate of 40 pounds per 1,000 square feet. For perennial beds, you could make a heavier application and add a layer of lava sand up to 2 inches thick before mixing it into the soil. You can use lava sand in any soil and with all plants. All lava sands help retain moisture, but the varieties with the highest paramagnetism work best. The manufacturer or supplier should have that information.
