Excerpt: We’ve been testing the High Drainage Cactus Soil Potting Mix with Mycorrhizal Fungi from Spike & Bloom for weeks, and the results are promising. The soil’s slightly acidic, gritty texture is ideal for succulents and cacti, ensuring proper drainage while preventing root rot—a common issue we’ve encountered. The inclusion of mycorrhizal fungi has quietly enhanced our plants’ root systems, absorbing nutrients more efficiently. We appreciate the 8-pound (4-quart) size, offering both value and versatility for multiple pots. While some prefer a more neutral pH, our acidic mix has suited our indoor desert garden well. The gritty composition ensures aeration, while the mycorrhizal additions provide a subtle boost to health. Overall, it’s a balanced choice for those seeking a reliable medium for thriving cacti and succulents.
