TO DELAY FLOWERING 
we Delay Hiswering by the Use of Artificial olight 
For this purpose select the better mid season and late varieties and grow normally. Disbuds and 
standards are more profitable than pompons, additional light reduces the number of buds produced on 
each spray reducing production. Planting date may be several weeks later than when no lights are used. 
Pinch all varieties late to avoid tendency for crown buds. 
Light with 40 watt lamps using tin reflectors hung at intervals of four feet over the bench. Three to 
ten foot candles are effective and economical. 
Your local lighting expert will explain these terms if you are not familiar with them. 
Start lights no later than August JOth. It is very important that lights are started before bud 
differentiation. Starting after this date may cause malformed flowers and long necks. 
Turn lights on at dusk and continue lighting three hours every evening or light for 60 minutes each 
night at midnight. Treat each night until you have treated %4 as many nights as you wish to delay 
flowering. In other words, for twenty days if you wish a thirty day delay in flowering. 
Take the first bud showing after light treatment is stopped. 
Pinch pompons the last time 30 days before light treatment is discontinued. 
Grow at night temperature of not less than 50 degrees where possible and consistent with local 
weather conditions. Cooler temperature will induce blindness. 
Be careful that the lights from the bench treated does not light a bench nearby that is not treated. 
This will cause part of the bench not under treatment to be delayed in flowering and consequently 
upset growing plans for bench not under treatment.
