Let's be honest, only the very best for your green amigos right? And none of them like to get their feet wet! That's why we've sourced you the finest lava rock we could find. Use it to line the base of your pot for better drainage protection or crush some lava rocks and mix in your soil for drainage in Cactus and succulent soils. This 3 litre bag should allow you to line two 10 inch pots or multiple 4- 6- or 8- inch pots.
