FINISH PGRs

TECH TIPS

3–5 sprays of Cycocel ® at 750 ppm will help control growth and speed flowering. Do not apply more than 750 ppm Cycocel ® or leaf edge yellowing may occur. Using a spray adjuvant such as CapSil ® will reduce the chance of leaf edge yellowing. Spray every 10–14 days depending on environmental conditions and plant growth. Stop applying Cycocel ® when flower buds are visible.

Geraniums are irradiance plants so the more light they receive the faster they will flower. Under short days or cloudy conditions it is beneficial to provide supplemental lighting of around 400 foot candles (4,000 lux) to speed up flowering. All geraniums are especially sensitive to bacterial diseases so be sure to start with clean containers, media and growing areas. Do not subirrigate or use recycled water. Do not grow a hanging Geranium crop over another Geranium crop. Media pH should not drop below 6.0 or the plants may suffer from iron and/or manganese toxicity. Avoid use of ammonium-based fertilizers to help maintain proper media pH. Instead, use nitrate-based Cal-Mag ® Plus fertilizers for the entire growth cycle of Geraniums. Keeping media saturated will promote Pythium root rot infections. Proper air circulation is very important at time of flowering to reduce likelihood of Botrytis flower petal blight.

TECH TIPS

2–3 sprays of Cycocel ® at 750 ppm will help control growth and speed flowering, and is recommended for pack production. Depending on environmental conditions pints may not need any plant growth regulator (PGR) applications except in the plug stage. Do not apply more than 750 ppm Cycocel ® or leaf edge yellowing may occur. Using a spray adjuvant such as CapSil ® will reduce the chance of leaf edge yellowing. Spray every 10–14 days depending on environmental conditions and plant growth. Stop applying Cycocel ® when flower buds are plainly visible.
