Pricking Out 



creeping species maybe divided. Cuttings in sand 

 root readily in a cold frame from July till September. 

 Soil, fibrous loam and peat or leaf mould, with 

 sand. The favourite species, angulata, is a pretty, 

 creeping, rock plant, with white flowers followed by 

 red berries, and is hardy in the south of England ; 

 the' rest require a pit or greenhouse from which 

 frost is excluded.

PRESLIA. 



A hardy, procumbent herb (prd. LabiatSB), suitable 

 for the rockery. Propagation, by division in spring, 

 and by cuttings in summer under a hand-light. 

 Ordinary garden soil. Cervina, June, pale purple, 

 is the only species (syns. glabriflora, villiflora, and 

 Mentlia punctata).

 white, yellow, or rosy flowers. Propagation, by 



PRATIA ANGULATA. 



PRENANTHES. 



Hardy herbs (ord. Composite). Propagated by 

 division in autumn or spring. Any well-drained 

 garden soil. The best known species are alba, 4', 

 autumn, white; purpurea, 4', August, purple; and 

 viruata, t', August, lilac. (For arborea and pinnata, 

 tee SONCHUS.)

 eriana, 1', March, white and crimson, is the best 

 known. 



PRESCOTTIA. 



Terrestrial stove Orchids (<ml. Orchidaceae), 

 bearing small Mowers ill dense spikes. Propaga- 

 tion, by division when commencing to grow. Soil, 

 equal proportions of fibrous loam and peat, with 

 sand, and a surfacing of sphagnum. 



(see Cala.n1 In-).

 base, in sand, in a case or under a bell-glass. Soil,

 PRICKING OUT. 



This terra is applied to the transplanting of 

 seedlings from pans, boxes, or beds. The operation 

 is done with the object of giving the seedlings 

 more room to grow either in boxes or frames. The 

 soil in the seed pans may have become sour through 

 overwatering or the length of time the seeds have 

 taken to germinate, or the seedlings may have 

 commenced to damp off, as Stocks often do; hence 

 the reason for having the operation done early. 

 Very small seedlings, being difficult to handle, are 

 best pricked out with a small peg. Tuberous 

 Begonias may require to be pricked out a second 

 time into boxes before they are large enough to be 

 potted. Bedding plants seldom require this more 

 than once.
