STONE FRUITS: THE PLUMS 



Varieties 



Learn what varieties of plums are grown locally. 

 Arrange the variety names under these headings as far 

 as possible: 



DoMESTiCAS Japanese American Hybrids 



Time of Blossoming 



Learn when all the different varieties of plums grown 

 locally blossom. Keep a record of the varieties that 

 blossom at the same time, as these are generally cross- 

 poUenized by bees and so should be planted near 

 together. 



Fungous Diseases 



Find black knots on plums, and wild and cultivated 

 cherries. Burn up all that can be seen and make it the 

 business of the school to help exterminate this disease in 

 the district.
