PLANT MATERIALS 



Grapes, rows 10 to 12 feet apart; plants 10 feet apart in rows. 

 Currants and Gooseberries, 4 feet apart. 

 Raspberries and Blackberries, 2 to 3 feet by 5 to 7 feet apart. 

 Strawberries (for field culture), 1 by 3 feet to 3H feet apart. 

 Strawberries (for garden culture), 1 to 2 feet apart. 



NUMBER OF TREES OR PLANTS THAT CAN BE 



PLANTED ON AN ACRE 



35 feet apart each way 35 



25 feet apart each way 70 



20 feet apart each way 110 



18 feet apart each way 135 



15 feet apart each way 205 



12 feet apart each way 300 



10 feet apart each way 435 



8 feet apart each way 680 



6 feet apart each way 1210 



5 feet apart each way 1745 



4 feet apart each way 2725 



3 feet apart each way 4840 



Rule for finding above data: Multiply the distance in feet be- 

 tween the rows by the distance the plants are apart in the rows. The 

 product will be the number of square feet for each plant or hill. This, 

 divided into the number of square feet in an acre (43,560), will give 

 the number of plants or trees to the acre.
