TECH TIPS

A total of 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 ten days to two weeks depending on environmental conditions and plant growth. Stop applying Cycocel ® when flower buds are plainly visible. Late Cycocel ® sprays can result in small and/or malformed flowers.

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) especially in the plug tray to speed up flowering. All geraniums are especially sensitive to bacterial diseases so be sure to start with clean plug trays, media and propagation areas. Geranium seed does not carry bacterial diseases so if you start clean you can stay clean. Do not subirrigate or use recycled water. Media pH should not drop below 6.0 or the plants may suffer from iron and/or manganese toxicity.

A total of 2–3 sprays of Cycocel ® at 750 ppm will help control growth and speed flowering, and is recom- mended for pack production. Depending on environmental conditions pints may not need any PGR applica- tions 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 ten days to two weeks depending on environmental conditions and plant growth.
