The Rose Lover's Calendar 

 of Operations 



These dates will be found relatively correct for the average season 

 in the latitude of Philadelphia. If you live North or South, make 

 usual allowance of about four days for every lOO miles of latitude. 

 Comparative altitude must also be taken into consideration. The 

 seasons vary; for example, the ground may be in good condition 

 and ready for digging one year as much as three weeks earlier than 

 it is the following spring. p^g^ 



MARCH 15. Such hardy Roses as you have already planted 



should now be pruned 14. 15 



MARCH 25 to 30. As soon as the ground can be well worked, 



plant new hardy Roses which are to be had dormant. Prune 



these even more closely than older established bushes . . . 11-15 



APRIL 10. Less hardy Roses, including the Everblooming class, 



should be pruned. Begin to remove the winter protection 



as the increasing heat of the sun permits 12-15 



APRIL 15. Roses are not immune from mildew and other fun- 

 goid contagious diseases, therefore it pays at this time to 

 spray with Bordeaux Mixture all your beds as well as nearby 



fruit trees and grape-vines 13 



APRIL 25 to 30. Finish uncovering and pruning your Roses. 

 Plant new ones (now or until the loth of May). A slight 



protection over the tops will prove an advantage 12-15 



MAY I to 10. As soon as plants are well set with foliage a spray- 

 ing with Nicotine or Sulpho-Tobacco Soap will act as a pre- 

 ventive against Aphis (Green Fly) 13 



MAY 20. As soon as buds begin to swell weak manure water 

 may be applied to the plants. Spray again to kill off the 

 aphis, otherwise they will multiply with amazing speed. . 10-13 

 MAY 25. Now starts the season's procession of bloom, led by the 

 sturdy Rugosas and the Yellow Briar Roses. Start feeding 

 the Hybrid Perpetual Roses with liquid manure 10 



This shows how "York and Lancaster" can be used (p. 25)
