African Violet Fertilizer: Beyond Brand Names to Numbers

Peter's Discontinued, Miracle-Gro Disappoints

Cathy's violets loved Peter's African Violet Food (discontinued when brand sold). Miracle-Gro for violets underperforms. She wants alternatives.

Brand Matters Less Than NPK Ratio

After 30 years growing and showing, expert Nancy advises: any brand with correct numbers works. Focus on the three main numbers (N-P-K) and secondary nutrients.

Recommended Formulas

• All-purpose year-round: 20-20-20 (balanced).
• Bloom boost (short-term): 15-30-15 (high phosphorus) for 2 months pre-show.
• Heavy bloom induction: 10-52-15 (very high P) for 2 weeks MAX—then switch back (low nitrogen weakens foliage).

Pro Show Schedule (Adaptable)

1. Months 1-2: 20-20-20
2. Months 3-4: 15-30-15 (disbud—remove all buds)
3. Months 5-6: 10-52-15 (forces massive bud set)
4. Months 7-8: 20-20-20 recovery
5. Supplements: Epsom salts (magnesium), fish emulsion (micronutrients), bloom boosters.

Home Grower Simplified

• Use 20-20-20 at 1/4 tsp/gallon with EVERY watering.
• Skip fertilizer Oct-Feb (rest period).
• Flush with plain water monthly to prevent salt buildup.
• Jack's Classic (Peter's successor) is excellent if available.

Key Takeaway

Don't chase brands. Master the numbers, respect the rest period, and your violets will bloom beautifully on any quality fertilizer.
