very forcing weather, or if the Eose be of a variety 

 that is apt to open too soon. Such a proceeding 

 slightly checks the sap, and the bud is likely to 

 grow a little more before opening. 



Pendulous Teas on dwarfs are apt to be splashed 

 with mud in heavy showers, and this forms an addi- 

 tional recommendation for standards for such varie- 

 ties ; no protection short of a universal mulch is 

 much good, but when all Eoses are wet, simply 

 dipping a splashed Tea face downwards a time or 

 two in a pail of clear water has often made it look 

 at least as well as its fellows. 



The effect of unshaded sun upon the colours of 

 Eoses seems peculiar : — undoubtedly it gradually 

 absorbs or weakens the yellow tint, which may not 

 only be preserved but also increased by close shading 

 or covering : and it appears also generally, at first, 

 to weaken the pink in Tea Eoses ; but a very hot 

 sun will sometimes bring a second red flush on 

 some, such as Marie van Houtte and Princess of 

 Wales, and I have seen such a flush come on old 

 blooms of Marechal Niel on a south wall in a very 

 hot time. 



On the other hand, all red H.P.s certainly come 

 much brighter in colour on a dull cool day after a 

 hot time, and there seems to be little effect in 

 shading to prevent the "burning" or browning of 

 the petals of the dark varieties. Generally, for Teas, 

 remember that very close shading increases the 

 yellow and destroys the pink or red tints : so that 

 all those varieties which have both these tints will 

 lose the pink and come of deeper yellow only, and 

 pale yellow Teas, like Madame Hoste, are much 

 deepened in colour.
