218 THE BOOK OF THE ROSE CHAP. 
very forcing weather, or if the Rose 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 Roses 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 
Roses 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 Roses; 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 Maréchal 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.
