CLOVERSET DEPENDABLE ROSES 
9 
We think it was the cold, rainy spring, which caused it to become so firmly 
established that it was nearly impossible during the summer to control. 
This condition existed all over the entire United States. 
Mildew, as the name describes, is caused by cold nights and occasionally 
affects Hybrid Tea Roses. The consistent use of Clotracide will help to 
prevent it. 
The sucking insects, or green lice, appear in the early spring in great 
numbers and must be controlled by a contact spray. To one gallon of 
Clotracide solution, add 1 tablespoonful Black Leaf 40 or 4 tablespoonsful 
Clotragard and spray thoroughly. Green lice appear in early spring for only 
a short time and after they disappear, the Black Leaf 40 or Clotragard may be 
discontinued. The spraying of the plants with Clotracide must, however, 
be continued every week during the entire season as long as the leaves 
remain green. (Full description and prices on Clotragard and Clotracide 
will be found in this catalog.) 
The leaf eating insects, slugs and skeletonizers, can be very easily con¬ 
trolled by the addition of the Clotragard as mentioned above or by adding 
one heaping tablespoonful of Arsenate of Lead to the gallon of Clotracide 
solution. If leaf eating insects appear at the same time as green lice, both 
the Arsenate of Lead and Black Leaf 40 may be used in the same solution, 
or 4 tablespoons Clotragard may be used instead. We recommend Clotra¬ 
gard for both sucking and leaf eating insects, Clotragard being a Rotenone 
spray, is both a contact poison and a stomach poison, and therefore takes 
the place of both Arsenate of Lead and Black Leaf 40. 
Clotracide and Clotragard when used together make a combination spray 
that is the most effective control for all Rose diseases we have ever used 
here in our gardens. 
WATERING. CULTIVATING AND FEEDING ROSES 
Roses are living, breathing, drinking, eating things and to insure great 
quantities of blooms and to withstand the attacks of the insects and diseases 
mentioned, they should be kept well fed, and watered. Watering is the 
most important of all and the most neglected. 
Roses as well as other "ground" plants require oxygen at the roots as well 
as at the tops. An ideal condition of the soil would be one dry enough so 
the roots could get plenty of air and wet enough so that the roots could get 
plenty of water for best development.
