i8o MANURES FOR FRUIT TREES 



the trees should be watered with a solution of the 

 same manure — two ounces to one gallon of water. 



Apple-trees become diseased, or do not bear a 

 full yield of fruit, or the fruit may be poor in 

 quality, if they are not properly manured and 

 pruned. Canker is caused by a fungus, Nectria 

 Ditissima, that lives beneath the bark and destroys 

 it. The invasion of this fungus is due to a 

 " niggard " soil and the want of proper manures. 

 Ill-nourished trees are prone to disease, and are 

 readily attacked by fungi and other enemies. 



Concerning canker in apple-trees, Mr. Douglas 

 states that the cause is due to " want of preparation 

 of the soil, and subsequent neglect of the special 

 requirements of each class of trees " ; and Mr. 

 Tonks states that " the cause is mal-nutrition, 

 the consequence of an imperfect provision in 

 the soU of the food required by the plant ; the 

 remedy, the supply of the food (manures) which 

 is deficient." 



Many orchard^ produce nothing like their full 

 yield of fruit through the want of proper and 

 economic manuring of the\soil. The soil should 

 always be judiciously manured to obtain both 

 quantity and quality of apples, as well as of other 

 fruits. Fruit trees require m^uring and attention 

 as much as ordinary! farm crops.
