the plant on the roots on the opposite - 

 side to you, so that the soil runs along 

 in the same direction as the roots. If 

 you throw it on the roots next to you, 

 it will run against their direction and 

 turn back their small points, which 

 would be nearly as bad as the old way 

 of shaking the plant up and down at 

 this stage. When all the roots are 

 covered an inch or two, the watering- 

 pot must come, with a large rose to it, 

 and you must water all over the surface 

 heartily, even if it is a rainy day. This 

 watering is to do the business of the 

 old shaking settle the finer particles 

 of the soil about the roots : the rest of 

 the soil, to the depth of four or five 

 inches, may be thrown on any-how, if 

 the lumps are broken small, so that 

 the surface is pretty smooth, and formed 

 into a shallow basin to hold the future 

 waterings. A stout stake, or stakes, 

 according to the size of the plant, 

 should be driven down before the eartli 

 is put over the roots, to keep the plant 

 from wind-waving. When large, bushy 

 evergreens are to be removed, their 

 branches must be tied up towards the 

 stem by passing a rope or strong cord 

 round them before commencing at the 

 roots. 



PLASHING is a mode of repairing or 

 modifying a hedge by bending down a 

 portion of the shoots, cutting them half 

 through near the ground to render 

 them more pliable, and twisting them 

 among the upright stems, so as to 

 render the whole more effective as a 

 fence, and at the same time preserve 

 all the branches alive. For this pur- 

 pose, the branches to be plashed, or 

 bent down, must not be cut more than 

 half through, in order that a sufficient 

 portion of sap may rise up from the 

 root to keep alive the upper part of the 

 branches. Where hedges are properly 

 formed and kept, they can very seldom 

 require to be thus maimed.

PLATANTHE'RA. (From platys, broad, 

 and anthem, an anther. Nat. ord., 

 Orchids [Orchidaceee]. Linn., 2Q-Gy- 

 nandrla l-Monandria.) 



Chiefly hardy orchids. Seeds, chiefly sown 

 as soon as ripe, in loose, mossy, peaty soil ; 

 peat and loam, with a little chalk j hardy ones, 



kept as Alpines, in a frame, defended from 

 heavy rains and from severe frosts, and the 

 atmosphere round them moist, by watering the 

 ground or moss on which they stand. Several 

 require the protection of a warm greenhouse. 

 Habenaria bifoliu and /am have been added to 

 this genus.
