improper soil mix on Indoor Bonsai
Quick answer
If your Indoor Bonsai has improper soil mix, the most likely cause is: Soil particle size and drainage capacity — oxygen diffuses 10,000 times faster through air than through water, so waterlogged soil suffocates root cells
Start here:
- 1. Screen all mix ingredients through standard window screen — discard anything that passes through
- 2. For general-purpose bonsai mix: 1 part grit (chicken grit or sand) + 2 parts sphagnum peat + 3 parts Turface (baked clay particles)

How to reverse improper soil mix on Indoor Bonsai
- 1
Screen all mix ingredients through standard window screen — discard anything that passes through
- 2
For general-purpose bonsai mix: 1 part grit (chicken grit or sand) + 2 parts sphagnum peat + 3 parts Turface (baked clay particles)
- 3
The goal is large inter-particle spaces that admit water while allowing air circulation around roots
- 4
Avoid clayey soils which compact and suffocate roots; sandy loam is preferred
- 5
Verify drainage: water must flow freely from drain holes within seconds of watering
- 6
Larger particles = better aeration = healthier roots
Keep improper soil mix off this Indoor Bonsai
Screen all ingredients before mixing; use 1 part grit + 2 parts peat + 3 parts Turface; ensure pots drain freely within seconds of watering
