eeeding of the season is disbudding. 

 About the beginning of May the trees 

 burst forth into a great amount of spra} r , 

 and much of this will be ill-placed; 

 and, indeed, if well-placed, much too 

 crowded. We are, of course, speaking 

 of wall or espalier trees, for there the 

 most attention is requisite. A pro- 

 gressive disbudding is best, the first 

 consisting in merely removing the fore- 

 right and back shoots, unless, as ob- 

 served with regard to the other stone 

 fruits, vacant spaces occur, when an 

 ill-placed shoot is better than none. 

 Shortly after this period, if the trees be 

 strong, gross shoots or robbers will 

 show themselves, which, when about 

 six inches long, should have the points 

 pinched off. In a few weeks more, 

 another disbudding will be expedient, 

 and by this time shoots of a proper 

 character for final reservation, may 

 be determined on. The latter may 

 be carefully tied or trained as soon 

 as convenient, and every shoot of a 

 doubtful character, in the thinning 

 out, may have the point pinched off. 

 The rest of the proceedings, indeed, 

 are so similar to the Peach, that it is 

 scarcely necessary to repeat them. 



Culture durimj the Rest Period. The 

 trees will require some pruning, and 

 this consists principally in thinning out, 

 and reducing the snags or stumps of 

 shoots, pinched back in the summer 

 previous. Our practice is to tie down 

 on the old wood, or otherwise train in, 

 as much of the shoot-jointed wood as 

 possible, without cramming it too thick ; 

 for most of this wood will become stud- 

 ded with blossom-spurs in the succeed- 

 ing summer. All that is not needed 

 may be cut clear away, as in the 

 Pear ; and all useless stumps also. 

 Where wood is wanting to furnish 

 blanks, some of the leading shoots may 

 be shortened back a little ; and, indeed, 

 any points may be shortened which 

 appear spongy and immature. The 

 trees may now be carefully trained or 

 nailed in, and, if necessary, receive any 

 dressing requisite for the insects.

PLUMBA'GO. Leadwort. (From j>lum- 

 l>um, lead, or a disease of the eye so 

 called, to which a species of Plumbayo 



was applied. Nat. ord., Leadwvrls 

 [Plumbaginacezje]. Linn., 5-Pentandria 

 1-MoHOfjynia.) 



Division of hardy herbaceous perennials, and 

 also seeds and cuttings ; cuttings of the tender 

 kinds, the side stubby shoots do best, but shoots 

 at almost every age and size will strike freely, 

 in sand, under a bell-glass, in summer, and 

 cither kept cool, or with a little bottom-heat, 

 according as the species. The tender species 

 require the greenhouse or the stove. Sandy 

 loam, and a little fibry peat and dried leaf- 

 mould.
