I bet the porous lava may have some advantages? I am not sure @tydynrain I will look it up. I'm so glad you have a blanket! 🌟🙏😊💚🌴🌅🌴🌄 !BBH !CTP
Ah, yes, I did find advantages @tydynrain planting in porous lava.

Better water drainage and aeration to plant root systems due Hawaii’s unique media porosity;

Minimal media compaction as cinder does not break down;
Slower decomposition of organic material, leading to a more stable media that is less prone to soil-based insects;
Less fungus, gnats, and disease.
