What Causes Premature Budding of Chrysanthemum Cuttings 
During The Spring Months, and What To Do To Prevent It 
Bud initiation can occur any time during the spring months, whenever your temperatures in the greenhouses 
are consistently 60 degrees or above, and the days are short enough to initiate bud setting. These conditions can 
occur any time until May Ist, depending upon the variety and locality on which they are being grown. Some vari- 
eties such as early shading varieties require very little short day treatment coupled with high temperatures to initiate 
buds. This same tendency to set buds readily is what makes these varieties desirable for early shading. 
In order to prevent this premature setting of buds, these same varieties should be placed where they can be 
given additional light during the early spring months. Use 60 watt bulbs spaced 4 feet apart and 30 inches above 
the plants. Use the lights for a period of two hours each night after dark until May Ist, then discontinue lighting.
