Several different procedures for freezing blueberries have been found to be 

 satisfactory, 



1. If the blueberries are blanched they may be froeen without added sugar 

 or dry sugar may be mixed with them at the rate of one pound of sugar ' 

 to five or six pounds of fruit, 



2. Fully ripe berries may be mixed with dry sugar at the rate of one 

 pound of sugar to five or six pounds of fruit. The fruit should be 

 stirred gently until sufficient juice coraes out of the berries to 

 dissolve the sugar, 



3, Fully ripe berries may be packed in containers and covered v.'ith a cold 

 sugar sirup (a 40 per cent or medium sirup is satisfactory for most 

 people ), 



4, The berries may also be packed dry v;ithout any sugar. 



The selection of vrfiich method of freezing to use should be based on the 

 ultimate use of the frozen blueberries and the tendencjr of the skins of the 

 fruit to become tough (on basis of previous experience in freezing blueberries 

 of particular varieties in a given area). 



During the past five years a number of different ' varieties of cultivated 

 blueberries, grown at the University of f-'Iassachusetts, as well as wild blueberries 

 have been frozen. The quality of the frozen berries has been evaluated on a 

 basis of flavor, texture and color. In general, all of the blueberry varieties 

 tested were considered as being of very good quality. Slight variations in 

 acidity and flavc v/ere observed among the different varieties, but it was a 

 matter of individ-^al taste as to v/hich variety v/as preferred. The varieties of 

 blueberries tested include: Cabot, Concord, Jersey, Pemberton, Pioneer, Rancocas, 

 Rubel, Scammell, Stanley, Y/areham and wild high bush berries,

7^.en Raspberry Leaves Turn Brown - Vfe frequently see the leaves on an 

 occasional raspberry cane turning brovm during June and TOonder v;hether 

 an insect or disease is responsible. The difficulty generally dates 

 back to the previous year when Spur Blight or Anthracnose infected 

 the new canes. Spraying with Ferraate during May helps to insure 

 healthy productive canes the following season.
