Easy to Maintain - Focus on the most satisfying part of maintaining a plant. Adding porous lava rocks instead of mulch to maintain plants like orchids, succulents, cacti, and bonsai trees ensures proper drainage while maintaining moisture.
Ideal Drainage - The porosity of lava rocks allows for excellent drainage while maintaining moisture within the soil to allow your newly potted, acid-loving plants to cultivate and flourish
Made in the USA - All Bonsai Jack soil products are lab-tested, are not dyed, and are chemical-free, unlike other brands that sell reclaimed organic matter which contain pathogens like nematodes and insects that can damage or kill plants.
