ROSES FOR GARDEN 
DECORATION. 
(Concluded from page 965.) 
Rose Enemies. 
The one most in our mind and gai lens 
just now is mildew. Everyone knows that 
this is a fungoid growth that appears 's a 
white mould on the foliage and stems ci the 
plants, and is particularly noticeable in the 
autumn. To guard the plants from injury 
by this enemy we must not wait until it 
apj^ears. Prevention is better than cu *e, and 
our first step must be taken as soon as 
the leaves of the roses appear in the spring. 
A simple solution, recommended by the 
Rev. J. H. Pemberton, ex-president of 
the National Rose Society, is Calverts 
carbolic soft soap: Boil “ l^lb. of this 
soap in 7^ quarts of water, and, when p c- 
paring a solution for spraying, add one part 
of this mixture to six parts of soft water. 
Mr. Pemberton says: “ Keep on with this 
for the season and you will never have mil¬ 
dew.” Other fungicides that are rei'om. 
menaed as being effective are Jeyesi’ Cyllin 
soft soap, potassium sulphide (using ^oz.*to a 
gallon of water, and adding the white of an 
to make the liquid more adhesive), and 
sulphuric acid. The proportions of the last- 
named I do not intend telling you, as I 
bedieve it to be a dangerous mixture to pre¬ 
pare, and requires great caution in applica¬ 
tion or the cure may be worse than the 
disease, and you will burn all the foliage off. 
Black spot, another disease which att itks 
the foliage, is a far too frequent pest 
amongst our roses. It is easily detected by 
the large black circular spots which appear 
about midsummer. It is most unsightly, and 
causes the early falling oft’ of the rose 
foliage. To prevent its recurrence spray 
with either of the fungicides I have men¬ 
tioned, and collect and burn all leaves show¬ 
ing any sign of the fungus. 
Rose rust appears in the summer on the 
foliage and wood in patches of orange spores, 
and in the autumn in small black points 
usually found covering the entire under sur. 
face of the leaves. These black points Vvill 
remain on the fallen leaves during the win¬ 
ter, and in the spring will start into fresh 
growth infecting the young leaves with the 
orange fungus I have just described. To 
prevent it appearing another season all in¬ 
fested leaves must be collected and burnt, 
and the plants sprayed in early spring with 
potassium sulphide, using ^z. to a gallon of 
water. 
We all know only too. well the aphis oi 
green-fly which reproduce themselves in such 
an extraordinarily rapid manner that one 
day our roses seem clean and the next the 
young growth is smothered with this pest. 
Fortunately a good insecticide, such as Abql, 
or soft soap and quassia, will keep them in 
check, or better still, perhaps, your finger 
and thumb will do the work equally w^ell. 
A more troublesome insect is the rose slug- 
worm, which devours the tissues of the rose 
foliage and causes disfigurement and injury 
to the plants. Spraying with hellebore 
powder will kill the pest and in the w^inter 
the surface soil beneath the attacked plants 
should be removed and replaced with freish, 
for the slugworms, when fully grown, fall 
to the ground and pupate in the soil in their 
cocoons. Another insect pest is the leaf¬ 
rolling sawfly. Growers wdio love their roses 
will be on the lookout for them, especially 
in the early part of the season, and wherever 
they detect a curled-up leaf will pick it off 
and crush the occupant, the best and only 
cure for many of the insect pests. 
Rose Gloire de Chedane Gui- 
noisseau. —This hybrid perpetual rose 
was raised and introduced by Guinoisseau 
and Chedane in 1908, and stands quite at 
the head of this section, though it is only 
during the last two seasons that its merits 
have been widely recognised. I look upon 
it as one of the most satisfactory roses in 
the garden. It is not so vigorous in growth 
as some, but it carries good foliage. E. .u.
