April. I THE FRUIT GARDEN. 335 



in small webs deposited on the branches, &c, animated by the 

 heat of the weather they soon overrun and devour the voun"- leaves, 

 whereby neither the trees nor fruit prosper in growth, and which 

 should be attended to, especially in young trees, by picking off the 

 webs, &c. before the insects animate considerably; and, if accom- 

 modated with a watering engine, as above suggested, you might 

 play the water strongly upon the trees, so as in the whole to 

 diminish the increase and spreading depredations of the vermin as 

 much as possible. 



Pruning. 



Pruning of all kinds of fruit trees should be finished in the first 

 week of this month, if neglected so long, especially the forward 

 blossoming kinds. See page 214. 



Protecting the Blossoms, fyc. of Wall Trees from Frost. 



Your early kinds of fruit trees, particularly those planted against 

 walls, may in forward seasons require protection for their blossoms 

 and young setting fruit from night frosts; the doing of which will 

 be found of importance. For the method, see page 219. 



Where the sheltering of these trees is practised, it should be 

 continued occasionally all this month; for although there are gene- 

 rally some fine warm days and nights, yet the weather is so very 

 uncertain at this season that we often have such severe hard frosts 

 as to prove the destruction of the blossoms and young fruit on such 

 of the above trees as are very forward and fully exposed. 



They may be protected with mats every cold night, and taken 

 down in the morning: if cuttings of evergreens are used as devised 

 last month, let them remain constantly till the fruit are past 

 danger. 



General Spring treatment of Fruit Trees. 



For the general spring management of fruit trees, see the Fruit 

 Garden and Orchard, last month. 



Grafting. 



For the various methods of grafting, &c. see the JS'ursery for last 

 month, and also for this. 



Raspberries. 



New plantations of raspberries may be made in the first week of 

 this month, but it would have been much better if that business had 

 been performed in the last, except in the eastern states, where it 

 may now be done with good success, as directed in page 221, which 

 see.
