- Rooting hormones are not required.
- Maintain a rooting temperature between 70 to 75°F.
- Average rooting time is 21 days.
- Fortunia petunias are naturally compact, so little pinching is necessary.
- In 6-inch and larger containers, pinch plants for extra fullness if desired.
- Maintain growing mix pH of 5.8 to 6.2 for better availability of iron.
- Allowing the growing mix to dry slightly between irrigations. Younger plants are especially sensitive to over watering.
- Good crop growth is obtained with 200 to 300 ppm N fertigation from a complete N-P-K water soluble fertilizer. Use "peat-lite" types.
- Growing mix EC of 2.0 to 3.0 mS/cm (SME).
- Flowering occurs only with long days (>13 hours photoperiod).
- When natural photoperiods are less than 13 hours, provide 10 foot candles night interruption or extended day lighting for 14 to 16 hours.
- Ideal day temperature: 65 to 70°F.
- Higher temperatures promote excessive growth/stretch.
- Lower temperatures (50 to 55°F) delay growth and flowering but may improve plant habit/quality.
- Crops can be moved to low heat structures (40 to 50°F) for holding.
- B-Nine or Bonzi (or others with similar active ingredients) are effective PGRs.
