African Violet soil requirements
Quick answer
For African Violet, soil requirements come down to this: African Violets require slightly acidic soil with pH 6.0-6.5 to optimize nutrient availability — at lower pH, phosphorus precipitates and becomes unavailable; above pH 6.5, micronutrients like iron and manganese become locked out, causing chlorosis despite adequate fertilization.
Start here:
- 1. Use commercial African Violet potting mix formulated to pH 6.0-6.5
- 2. Create custom mix: equal parts peat moss, perlite, and vermiculite
What soil requirements mean for African Violet

How to meet African Violet soil requirements
- 1
Use commercial African Violet potting mix formulated to pH 6.0-6.5
- 2
Create custom mix: equal parts peat moss, perlite, and vermiculite
- 3
Add perlite (20-30%) to improve drainage and aeration in any commercial mix
- 4
Incorporate peat moss to help retain moisture while maintaining acidity
- 5
Avoid compacting soil when potting — loose soil allows proper root oxygenation
- 6
Repot every 6-12 months with fresh mix to maintain pH and nutrient availability
- 7
Sterilize soil before use to eliminate pathogens
Keeping African Violet in range
Use commercial African Violet potting mix or create a custom blend with peat moss, perlite, and vermiculite; never use garden soil or heavy clay-based mixes that compact and suffocate roots.
