HOW TO GROW ROSES 



The Rose-Lover's Calendar 

 of Operations 



These dates will be found relatively correct for the aver- 

 age season in the latitude of Philadelphia. If you live north 

 or south, make the usual allowance of about four days for 

 every i oo 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 

 as much as three weeks earlier one year than it will be the 

 following spring. 



March i;. — Such Lardy roses as are already planted should 

 now be pruned. 



March 2; 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. 



April 10. — Less hardy roses, including the Everblooming class, 

 should be pruned. Begin to remove the winter protection as the increas- 

 ing heat of the sun permits. 



April if. — Roses are not immune from mildew and other fungoid 

 contagious diseases; therefore it pays at this time to spray with bordeaux 

 mixture all your rose plants as well as nearby fruit trees and grape-vines. 



April 2; to 50. — Finish uncovering and pruning your roses. Plant 

 new ones (now or until the middle of May). A slight shading of these 

 from the sun will prove an advantage. 



May 1 to 10. — As soon as plants are well set with foliage, a spraying 

 with rose nicotine or sulpho- tobacco soap will act as a preventive 

 against aphides (green fly). 



May 20. — As soon as buds begin to swell, weak manure-water may 

 be applied to the plants. Spray again to kill off the aphides, otherwise 

 they will multiply with amazing speed. 



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. 



June 1. — With this month we see the true glory of the "Feast of 

 Roses." 



June 5. — Watch for the rose beetle and rose slug, and spray every 

 ten days for three weeks with a half pound of arsenate of lead to ten 

 gallons of water. 



June jo. — Begin to nourish the Teas and Hybrid Teas with liquid 

 manure. (Page 17.) You'll soon see the result. 



June 20 to 50. — Now the Teas, Hybrid Teas, and Climbers begin 

 blooming in abundance. Cut your blossoms freely. Look out for mildew 

 and apply the remedy. 



July 1. — Keep the soil well stirred. A dust mulch at this season is 

 important.
