African Violet Care: The Complete Indoor Growing Guide

Saintpaulia (African violet) is the gateway houseplant—compact, nearly continuous bloom, thousands of cultivars from micro-minis (6″) to large standards (16″+). Dark fuzzy leaves, flowers in blue, purple, pink, red, white, bicolors, and fantasies. Here's the precise care protocol.

Soil: The Foundation

Loose, well-drained, slightly acidic (pH 6.0–6.5). Ideal mix: 1 part sphagnum peat moss + 1 part perlite or vermiculite. Drainage is non-negotiable—crown rot kills fast in heavy soil.

Light: Bright Indirect Only

• North or east window (northern hemisphere).
• Rotate ¼ turn weekly for symmetrical growth.
• Too little light → no blooms, yellow leaves, elongated petioles.
• Too much → brown leaf spots, bleached flowers.
• Artificial light works: 12–14 hrs under 40W fluorescents/LEDs, 12″ above plant.

Humidity & Temperature

• Ideal: 65–75°F, 50–60% humidity.
• Below 60°F → dark, wilted leaves (chill damage).
• Above 80°F → slowed growth, bud blast.
• Humidity hack: pot on pebble tray with water (pot above water line).

Water: The Balancing Act

Water when top 1″ of soil is dry. Use room-temp water. Never wet leaves—causes permanent white spots. Bottom-water (sit in 1″ water 30 min) or careful top-water at soil level. Drain fully.

Fertilizer: Weakly, Weekly

20-20-20 at ½ label strength every watering, or full strength every 2 weeks. Pale leaves + slow growth = underfeeding. Salt crust on soil = overfeeding (flush with clear water).

Pro Tips

• Repot annually in fresh mix—old soil compacts.
• Remove spent flowers and old outer leaves.
• Propagate from leaf cuttings in perlite/vermiculite.
• Mealybugs? Alcohol-dipped cotton swab on each bug.

Follow this, and you'll have blooms 10–12 months a year. The addiction starts with one plant.
