Reposting my rainbow soil for caudex, succulent, cactus, begonias. Highly porous, high moisture and mineral retention and of course highly aesthetic 😏.
All divide equally: 1. Akadama soil (moisture retention and drainage) 2. Zeolite (nutrient retention and decontaminates soil) 3. Pumice (drainage and much better than perlite) 4. Lava rock (natural minerals)
For fertilising: 1. High K (potassium) content for succs and caudex for root growth 2. High N (nitrogen) for humongous leaves
