OUTDOOR ROSE GROWING 



It has been thought that black spot was merely 

 a ripening of the leaves of the plant, and a natural 

 condition. At Cornell it has been proved that black 

 spot is absolutely traceable to a fungous growth, and 

 Professor Massey is quoted: "The organism can be 

 isolated at will, and the disease readily produced by 

 inoculations." 



As the nights become still colder the blooms will, 

 of course, take longer to develop; nevertheless the 

 roses make a fight to give flowers and the late 

 bloomers continue to do so until about the middle 

 of November. From the middle to the last of Novem- 

 ber is the time roses should be given proper winter 

 protection. 



The first thing to do with all ordinary bushes is 

 to cut them down to an approximate height of a foot 

 and a half. They will nearly all die down to this 

 height or below in any event, and by cutting off the 

 bushy tops damage by high wind is prevented. The 

 mulch should at this time be removed and saved 

 for the following spring. 



The matter of hilling up has been noted, but is so 

 important that it is repeated. It consists of heaping 

 the ground up around the bush. It is well to add 

 some top soil to the bed and hoe this up in a little 

 mound around each plant to a height not less than 

 six inches above the bed level.
