April] THE FRUIT GARDEN. ^ 335 
in small webs deposited on the branches, &c., animated bj the 
heat of the weather they soon overrun and devour the young 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, 8fc. 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 Nursery 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.
