This Spike \u0026amp; Bloom blend swaps heavy peat for mineral particles and a touch of organic matter so the substrate stays open, drains quickly, and resists collapse. Mycorrhizal fungi are included to foster a beneficial root-soil partnership that can expand water and nutrient access beyond the physical root zone. The result is a stable, free‑draining foundation suited to frequent watering, repotting, and the precise moisture control bonsai culture requires.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this soil improve drainage for indoor and outdoor bonsai?\u003c\/h3\u003e\n\u003cp\u003eThe mix emphasizes mineral components that create permanent pore space, so water moves through rather than pooling around roots.
