SEED FINISHING
FINISH PGRs
TECH TIPS
A total of 2-3 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 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
If necessary sprays of Cycocel ® at 300–500 ppm will help control growth. 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.
Ivy 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.

B-Nine ® WSG at 2,500–5,000 ppm or A-Rest ® at 1–3 ppm
It is critical to not plant the plug too deep so as to bury the crown. Buried crowns can lead to hard, distorted growth or crown rot. Space plants on time so the leaves from one plant will not cover the center of another; shading the crown will delay flowering.
