easy grow guide salpiglossis royale (F1 Salpiglossis sinuata)
Plug Production: 512 or 288 plugs Sowing/Media:
Use a well-drained, disease-free, peat based plug medium with pH 5.5-5.8, EC <1.0 mmhos. No covering needed. Use pelleted seed for best sowing results. Sow as Petunia. Keep medium uniformly moist, not saturated and reduce once cotyledons are open. media temperature should be 72-75°F (22-24°C), keep light levels <2500 f.c. Light benefits germination and daylength of 14 hours or above will improve seedling quality. Media temperature should be 68-72°F (20-22°C). Once cotyledons are fully open, dry the media down between irrigations to improve rooting, control floppiness and encourage even seedling growth. Keep light levels between 2500 and 3000 f.c. Again >14 hour days will improve growth rate and HID lighting will be beneficial during periods of low light. Feed every other watering with 15-5-15, 17-5-17 and even 20-10-20 if light levels are high. Media pH at 5.5-5.8 definitely <6.5, EC 1.25-2.0 mmhos. This should take 7-10 days. Media temperature can be lowered to 62-65°F (16-18°C). Dry down between irrigations. Keep light levels around 3000 f.c. Fertilize as required using 13-2-13 to help tone seedlings before transplanting Use a well-drained, disease free, peat-based growing mix with pH 5.5-5.8 and EC <1.5 mmhos. Avoid burying plugs to keep the crown of the plant out of the media. Temperatures for rooting out after transplant should be 65-68°F (18-20°C) Temperatures for growing on can be lowered to 62-65°F (16-18°C). Avoid growing cooler than 60°F (15°C) before flowering as cool temperatures will delay flowering. Light levels should be maintained at 3000 - 5000 f.c. HID lights can be used to extend daylength beyond 14 hours during periods of low light. This will promote more compact growth and earlier flowering. Night break lighting can be used but can cause stretching. Practice a good wet/dry moisture cycle to control height and root growth. Salpiglossis can tolerate mild wilting. Feed 1–2 times per week with 150 – 200 ppm N from 15-5-15, 17-5-17. Keep media pH 5.5- 5.8, definitely <6.5 and media EC 1.25 – 2.0 mmhos (saturated paste). Use sprays of B-Nine (1000-5000 ppm), A-Rest (3-7 ppm), Bonzi (10- 30 ppm), or Sumagic (5-15 ppm) as needed. You can drench with Bonzi (1-5 ppm) or Sumagic (0.5-3 ppm) when plants are up to size and flowering to control growth. It is best to run your own trials to avoid overdosing, as weather and cultural regimes can affect the requirements. Growing dry at >14 hour days can reduce the need for PGR applications.
