branches on varieties like Radiance, Lady 
Ursula, etc. This may be done roughly and is 
mainly recommended to prevent unnecessary 
evaporation when so much of the plant is ex¬ 
posed to strong winds and sun. 
CULTIVATING AND WATERING. Most 
everyone knows that it is important to keep 
the soil in a Rose-bed loose and aerated. A 
summer mulch of peat moss, tobacco stems, 
grass-clippings, or other clean litter is always 
beneficial. We like to see the peat moss hoed 
and worked into the upper soil-layer. Roses 
do not need to be hoed or cultivated deeply 
so long as the job is done regularly and 
thoroughly. 
Never allow Rose-beds to become dry 
throughout the entire growing season from 
early spring until late fall. We know of many 
instances where Roses are suffering, especially 
during July and August, from lack of water. 
In many cases the gardener imagines his 
problem is one of feeding, whereas all that is 
necessary is a thorough soaking. The theory 
that Rose-gardens must be especially well 
drained has been carried to the extreme in 
this country. It is different in the Pacific 
Northwest and in foreign countries, particu¬ 
larly England, where climate and atmos¬ 
phere are continually moist. Therefore, our 
recommendation is always to water, and water 
plenty, during prolonged dry spells. 
Diseases and Insects 
BLACK-SPOT. There are two main general diseases to which the Rose is subject; viz., 
Black-Spot and Mildew. The former, as its name indicates, appears as a black or brownish 
spot on the foliage. It rarely puts in an appearance until about the close of the first blooming 
season in June. It always appears first on the lowest foliage and works upward. As a result, 
this disease will often practically defoliate the bush. It will not kill the latter but will check 
the growth and bloom for the season and so weaken the plant that it may die back over winter. 
MILDEW. This is shown in a grayish, crinkled appearance of the foliage. Like black-spot, 
it is of a fungous nature, the spores fastening themselves on the bottom of the leaf and spreading 
rapidly unless checked. It is most likely to occur where the air-circulation is defective or 
confined and particularly after cold nights following warm days. 
Treatment of Both. The two diseases may be prevented by the use of the Massey Dust, a 
preparation consisting of nine parts of a very finely prepared sulphur (not flowers of sulphur) 
and one part lead arsenate. This is now manufactured with the addition of a green coloring 
matter to make it inconspicuous on the foliage, to increase its fungicidal value and is sold as 
Pomo-Green, with or without nicotine. With the nicotine sulphate added, it is a complete 
fungicide and insecticide combined. We have used Pomo-Green on our extensive Rose-plantings 
for the past eight years. During this time we have also experimented with many other com¬ 
mercial fungicides, but none have prevented black-spot and mildew so easily as Pomo-Green 
used as a dust. We therefore recommend it highly and are pleased to offer it as a direct service 
to our Rose patrons.

Pomo-Green is not for Roses alone, but for the entire garden. 
Another very good commercial fungicide and insecticide is Tri-ogen. This must be used as 
a spray and prevents black-spot and mildew. Prices on request. 
When to Apply Dust or Spray. Best applied in early morning or late in the evening when 
the air is quiet. Since prevention rather than cure must be the spirit of complete control of 
black-spot, it is essential that you start dusting or spraying as soon as the plants are in active
