86 PICTORIAL PRACTICAL ROSE GROWING. 
Roses with Green or Blind Centres. 
These troubles can hardly, with perfect consistency, be 
included amongst Rose enemies, inasmuch as they are not the 
work of insects or fungi. They are, however, very real. 
Roses frequently come with green centres when the plants 
are unhealthy or weak, rarely when they are vigorous and 
sound. The remedy, therefore, lies in improved cultivation. 
Those who treat soil and plants on the lines laid down in 
previous chapters will not, it is hoped, have much disappoint- 
ment on this score. 
“Blind” Roses, that is blooms which appear to become 
petal-bound in the centre while still in the bud stage, and 
unable to open, are, unhappily, common in town gardens after 
the first year or two of their existence. Roses are not town 
plants, and dislike an impure, fog-and-acid-laden atmosphere. 
The townsman should not run the risk of almost certain failure 
by growing a large number of Roses, but should carefully 
choose a few; then, with good culture, he may achieve success- 
ful results. 
Chapter: 11.—Bow to Exhibit Roses. 
WHEN the Rose grower becomes an exhibitor he develops into 
a rosarian. 
It would be futile to moralise on the hollowness of the 
reasons by which the great metamorphosis comes about.
