Rose perfume, which is due to the presence of an ex¬ 
tremely volatile oil, is more apparant when the sun is low 
in the sky, as at that time the Roses are able to produce 
more oil than the sun can evaporate... In the fields of 
Damask Roses in Europe, Rose petals used for commercial 
purposes are picked at four or five in the morning... This 
past Decembre Attar of Roses sold there for $400 per 
kilogram. 
ting more and more so as the number grows larger. 
It has been found that Roses are very tolerant. They 
will grow in a soil from 4.5 P H up to 8 P H , but the 
best growing conditions seem to be found in a soil that 
is neutral or slightly acid—that is, around 6 or 7 P H . 
Lime, in almost any form, can be used to make soils more 
alkaline and sulphur to make them more acid.. 
FEEDING 
Bonemeal is the only fall fertilizer for Roses that is 
recommended. After the ground has become frozen, apply 
fresh strawy manure if it is procurable. In the spring, 
when the bank of soil is removed, apply Wyant Rose Food, 
or else a complete chemical fertilizer, to the established 
plants but not to newly set Roses. Wyant Rose Food is 
recommended, because it is of organic composition rather 
than chemical, and even after long usage does not make 
the soil toxic, nor burn, as a chemical fertilizer will. Much 
fertilizing will produce much bloom, so during June or eariy 
July make another application to new as well as to estab¬ 
lished Roses, and then again in the latter part of August, 
not after September 1st. Each time, apply about a handful 
to medium strong bushes, less to weaker, and more to 
stronger bushes.
