Prolonging The Blooming Period 
Of Chrysanthemums 

To prolong the period of bloom into December and January, the 
varieties desired may be planted late in June or July; about three weeks 
before buds show additional light should be given for approximately as 
long a period as the extension over the normal time is wanted. Thus, 
if a variety blooms normally in mid-November, a 30-day treatment will 
bring it in about mid-December. If wanted for January, the treatment 
should continue for 45 days or longer. 
The additional light should be in the form of Mazda lamps (clear 
or frosted). The lamps should be stretched over the bench using 25 to 
40 watt sizes, five feet above the plants, and spaced five feet apart. Suit- 
able reflectors are necessary—either the porcelain lined R.L.M. dome 
reflectors or deep aluminum cake tins with a hole punched for the 
lamp. The light should be turned on just before dusk and continued 
for three to four hours daily. 
Unless this light is applied before the formation of buds, crippled 
flowers may result. The cost of the installation is very small in com-” 
parison with the results secured. Mid-season and late varieties should 
be used. ,
