Indianapolis Mums delayed by lights for Christmas bloom. We find them far superior to the varieties that are catalogued for normal fiower- 
ing during this period. 
They are better colors, free of disease, and will flower when you wont them! Geo. K. Ball in the photo.

Why ‘Round the Year Flowering? 
New, continuous flowering mum programs are 
appearing constantly—and in all sections of the 
U.S. Reasons, as we see them: 
1. Good returns—over $3.00 per sq. ft. per year 
net after commission, for a conservative aver- 
age. 
2. Steady, low work load. You plant, prune, pick 
flowers every month. 
3. Steady returns. 
4. Continuous production is in tune with the 
steady demand of markets, or your store if you 
retail. 
>. Mums will keep well, offer a wide variety of 
colors and forms. 
Correct Temperatures—Be Generous! 
Continuous flowering should not be attempted 
until the grower is equipped to hold a 62° mini- 
mum from planting till color starts to appear. Pre- 
vious recommendations called for 60°, but several 
years experience have convinced us that less than 
62° minimum will result in more or less blindness 
on cold ends of houses. Cooler air down near plants 
and varietal differences make this extra 2 degrees 
a must for dependable, even bud set. 
Our temperatures for off-season: 
Nights Cloudy Day Sunny Day Period 
C2 68° lide From planting cuttings 
till color shows. 
Sea 58° 67-70° After color shows (re- 
duce temperature grad- 
ually — never faster 
than 3° per week.) 
We hold different temperatures in a given house 
(at night) by dropping sateen igloos (see page 14) 
over the beds that need the higher temperatures, 
turning heat into pipes under these beds. 
On some ranges, layout of heating system, 
benches etc., makes it impossible to lower temper- 
atures on individual beds during the flowering pe- 
riod. In such cases, if varieties are selected with 
this problem in mind, the crop can be grown at a 
straight 62° minimum through the winter. This 
does eliminate some desirable varieties (Silver- 
smith, for example) but many continuous flower- 
ing programs are operated this way—and produce 
excellent quality winter flowers. . 
50 Degree Winter Mums 
Quite a few varieties actually will set bud and 
flower at regular 50° temperatures. However,
