What are the best amendments to improve cactus soil mix in my organic farm?
I'm currently managing my small organic farm in California, and I’ve been experimenting with different soil mixes for my cacti. While I understand the general principles of creating a cactus soil mix, I'm curious about specific amendments that could enhance the health and growth of my plants. My garden setup has varied conditions since some cacti are in pots while others are directly in the ground. I’ve tried using sand and perlite, but I'm wondering if adding something like crushed granite or other amendments might better support drainage and aeration. I'm passionate about using organic materials wherever possible, so if anyone has recommendations for organic amendments that can be used in cactus mixes, I'd truly appreciate your insights. Can anyone help with what specific amendments I should consider to optimize my cactus soil mix?
