SUMMER WORK IN THE ROSE GARDEN: INSECTS; 

 DISEASES; SUMMER PRUNING; KEEPING CUT 

 FLOWERS FRESH 



Continued attention is necessary in the rose garden if 

 you would make sure of an abundance of perfect blossoms. 

 No matter how strong and healthy the plants may look, 

 and even though the first buds may have opened, serious 

 injury still threatens from a number of sources. Protec- 

 tion from insects and diseases, summer mulching, extra 

 manuring, summer pruning, training new growth, and so 

 forth, are among the things that the rose grower must keep 

 in mind and give attention to throughout the season. 



The rose is hable to injury from many insects and diseases. 

 The most annoying and pernicious intruders are the rose 

 bugs or rose beetles. These insects are particularly hard to 

 combat because they generally appear when mature and 

 ready to do the maximum amount of injury with a mini- 

 mum susceptibility to insecticides. If neglected they will 

 entirely defoliate even large plants. The first attacks, 

 however, are usually confined to open flowers and buds, 

 particularly of light-colored varieties. The beetles are most 

 prevalent in sections where the soil is sandy, but as they 

 can travel long distances, and make themselves at home on 

 wild roses as well as on the cultivated sorts, few localities 

 seem to be immune from their attack. 



Paris green, one pound to 150 to 200 gallons of water, 

 and arsenate of lead, five pounds to fifty to seventy-five 

 gallons of water, are effective poisons; but Paris green is 

 likely to injure the foliage, and arsenate leaves it discolored. 

 Unless the beetles attack in overwhelming numbers, by 

 far the quickest, surest and least injurious method of
