882 CALENDAR OF OPERATIONS, [chap. xit. 
soil, plentifully supplied with water. The 
box edgings may be pruned in this month, 
but they should never be clipped. A garden¬ 
line should be stretched along the edging, at 
the proper height, generally about four inches 
from the ground, above which the highest 
point of the box should not reach; and the 
box should be cut down to this line, every 
shoot being cut in a slanting direction to a 
bud, and only every alternate shoot suffered to 
reach the line. Hardy annuals also may be 
sown in this month, if the sowing of them 
was neglected in March. The ornamental 
kinds of Ribes and Berberis will begin to 
come into flower with Magnolia conspicua, 
and the common almond. 
In the kitchen-garden, April may be 
called the grafting month, though many 
gardeners begin to perform that operation in 
March. In the culinary department, those 
vegetables that require transplanting, such 
as celery, sea-kale, cauliflower, &c., are ge¬ 
nerally planted out in April. The peas and 
beans are hoed up, as are the potatoes; the 
asparagus and artichoke beds are dressed ; 
and the onions, turnips, &c,, are thinned..
