beauties like these!

GENERAL CULTURE 
ee | 
“Resistance” to Aster wilt does not mean complete “immunity”! 
While the degree of resistance offered by these strains may vary 
somewhat in different localities, there is no doubt that they are 
far more satisfactory than non-resistant strains. Our past ex- 
perience indicates that changing the location of the Aster plant- 
ing regularly (or steam sterilizing) is a worth-while safety pre- 
caution. We sow them 6 weeks before planting out date. Three 
weeks after sowing, the seedlings go into 24-inch plant bands; 
three weeks later we plant them without removing bands, which 
helps minimize transplanting losses. We space them a foot apart 
each way in beds so that conventional wire and string may be 
used for supports. We find cloth house protection a necessity if 
superior quality is wanted.

spring greenhouse Aster crops were the best paying crops that they 
had on their place. While Asters can be flowered any month of 
the year, the spring and early summer months seem to be the 
most profitable. The only important requirements are: 50° night 
temperatures and additional lighting, which must be supplied 
continuously from the seedling stage until plants are 20 to 24 inches 
tall. The only exception is the period from May 1 to September 1, 
during which day length is long enough. 60-watt bulbs with re- 
flectors, spaced 5 feet apart, or the lighting set-up you use for 
Mums is satisfactory. Lights must be turned on from sundown 
to 10 P. M. daily. 
Spacing may be anywhere from 8x8 to 10x10 inches—we use 
the latter for somewhat better quality. White Ball, Pink Ball and 
Rose Ball are especially fine for off-season culture. Azure Ball and 
Purple Ball do equally well, but these colors will be wanted in 
lesser quantity. Use sterilized soil for best results. 
The following schedule worked out at Ohio State checks closely 
with our own experience where a 50° night temperature was used.
