๐ฑ Ideal Soil Conditions for Maximum Results
1. Soil Type:
Use well-draining potting mix with peat, perlite, or vermiculite
Avoid heavy or compacted soils that may retain excess water
2. Soil pH:
Target range: 6.0โ7.0 (slightly acidic to neutral)
Adjust with lime or sulfur based on soil test if outside this range
3. Moisture:
Keep soil evenly moist but never soggy
Ensure containers have proper drainage holes
4. Organic Matter:
Incorporate compost or worm castings for enhanced nutrient retention and microbial health
