ROSE DEVELOPMENT FROM 1917 TO 1920 



after its second year, it should be root pruned or moved to insure 

 blooming wood. Its habit is most vigorous and hardy and when well 

 grown it blooms most prolifically from spring until frost. This 

 rose is in a class by itself, its only fault is a sUght tendency to mil- 

 dew, which may be controlled. It must be given a situation in the 

 open away from a wall or building. 



In hardy climbing roses with one period of bloom two new ones 

 have appeared which are absolutely distinct and worth while. 

 Paul of England has put out Paul's Scarlet-Climber, a rose of 

 fine form and splendid habit. It is a brilliant scarlet and is a fine 

 acquisition to this section. 



It has been our good fortime to breed a crimson maroon climber 

 •which Dr. Robert Huey has chosen from among our seedlings to 

 bear his name. This rose is a very dark color and blooms most 

 profusely during its season. It is semi-double and retains its petals 

 and color for a long period, besides being of vigorous growth.* 



Among the other hardy roses tested, two old introductions have 

 shown so much beauty that they should be added as equal to the 

 best of the Wichurianas; viz., Paul Transon, apricot, and Axberic 

 Barbier, yellow. 



In culture, valuable improvement in the treat- 

 ment of black spot and mildew has been brought to 

 notice by Doctor Huey, who found it practiced in 

 the garden of Edwin M. Rosenbluth of Walling- 

 ford, Pennsylvania, whose roses are so noticeably 

 free from these evils that with his permission the 

 methods used are given in full, with appreciation 

 of his courtesy. 



First — Affected foliage must be removed both from the plants 

 and ground and afterwards burned. In an aggravated case, it 

 Would be well to first spray with Bordeaux Mixture, using five 

 ounces of the paste to a gallon of water. 



Second — If late in the season, all foliage should be removed — say 

 within a period of two weeks — and burned. 



Third — During the first part of November the beds should 

 receive a very hght dressing of Commercial Sulphate of Iron. In 

 severe cases repeat this in the spring, on removing the litter, and 

 use also a Ught spray of Bordeaux Mixture. 



Fourth — About May fifth start spraying Hghtly with Ammoniacal
