THE GARDENING WORLD 
Septembers, 1905. 
Mildew on Crimson Rambler. 
For some time past I have been dusting the 
foliage of this useful Rose with flowers of sulphur, 
but it does not seem to have much effect in reduc¬ 
ing the mildew, of which I send you a sample. 
Is there any remedy for the trouble which is dis¬ 
figuring the plant? (A. U. Roberts.) 
The mildew has now passed into its second 
stage, which is much more difficult to destroy than 
the early stage at the beginning of the season. 
All you can do now is to cut away and burn the 
very worst of diseased shoots or branches, or even 
leaves. You could then spray the plants with sul¬ 
phide of potassium, otherwise known as liver of 
sulphur, to act as a check upon the further spread 
of the fungus. This should be used at the rate of 
l oz. to a gallon of water. Next year you should 
commence to spray earlier, so as to reduce the 
amount of fungus that could possibly pass into 
the second stage, which is most difficult to 
destroy. 
Earwiffs on Dahlias. 
My Dahlias are very much infested with some 
nsect, which eats the leaves and flowers. I be¬ 
lieve they must be earwigs. Can you tell me how 
to deal with them? (J. C. R.) 
You should get some dry moss and put a small 
quantity of it inside thumb pots or small pots of 
variable sizes, whichever you may have on hand. 
Place one of these pots on the top of the flower¬ 
pots, and you will then be able to discover the 
insects which are infesting your Dahlias. We 
think that in all probability they are earwigs. 
They should, of course, be destroyed when caught. 
Garden Peas Mildewed. 
A fine late crop of Veitch’s Perfection Pea here 
has quite succumbed owing to a bad attack of 
mildew. The plants now seem quite hopeless. 
Could you suggest the cause, and say how it could 
be prevented another year? (M. C.) 
The fungus which has destroyed your Peas is 
the common Pea mildew (Erysiphe Martii). If 
you had in the very earliest stages of the disease 
loosened up the surface of the ground, mulched it 
with rank litter of some sort, and then copiously 
watered the ground, you would have done much 
to save the Peas by inducing a vigorous growth. 
It was no doubt the very hot and dry weather 
in July that did all the mischief, and you could 
have guarded against it by being prepared in the 
way we describe. The fungus itself can, of 
course, be attacked with some degree of success 
if done in the very earliest stages. This might 
consist of dusting the foliage with flowers of sul¬ 
phur or spraying with sulphide of potassium. 
After the fungus has advanced beyond a certain 
stage the constitution of the plant gets sapped, 
and spraying is then practically useless. 
Sweet Peas a Failure. 
I made a sowing of Sweet Peas in April to form 
succession to the early ones. During August 
they produced a few flowers only, but for what 
reason I cannot say. Can you suggest a cause 
for such behaviour? (S. W. R.) 
It would be difficult or impossible to say for 
certain what was the cause of failure, although 
we can make suggestions. In the first place, 
April is a very late period at which to sow Sweet 
Peas, as they rarely succeed when the season 
following turns out to be dry and warm. Sweet 
Peas to be a success should never be sown later 
than the middle of March, and those who have 
tried sowing in October and November have been 
quite successful, getting large quantities of 
flowers at a much earlier period than if the plants 
had been sown in spring. Possibly also the seeds 
were sown too thickly, which is a common fault 
with many in the sowing of annuals of various 
kinds. When the plants are crowded they never 
attain any vigour, and can only produce a few 
flowers on the main stem, being unable to throw 
out side branches. You may also have had 
Sweet Peas in the same ground for several years 
in succession. No doubt, also, the ground was 
unusually dry during July. 
Two Colours in a Dahlia. 
A Dahlia which I planted in my garden last 
June has produced several flowers, one half of 
each being red and the other tipped with white. 
Can you say if this is a common occurrence? 
(P. M.) 
It is a fairly common occurrence in gardens, 
but is more likely to happen in certain varieties 
than in others which are fairly constant and do 
not sport in this way. No doubt it is a fault of 
the varieties which you have in your collection. 
They may please your fancy or otherwise, but 
this method of variation is not uncommon. 
Replanting Montbretias. 
My Montbretias have flowered well this year, 
indeed twice as well as last year. Do they ever 
require transplanting, and how often should it 
be done? (T. Wallis.) 
We should be guided by circumstances; so long 
as your plants continue to flower well or even 
satisfactorily, you should not disturb the bulbs 
at all. Other people in districts where Mont¬ 
bretias are of easy cultivation find that it is 
necessary to transplant them every two years, 
so that the bulbs could be spaced out at the 
proper distance apart. You should be guided 
much in the same way. When the plants get too 
thick to flower well, you should lift and trans¬ 
plant them in the following winter or early 
spring after the foliage has thoroughly died 
down. 
A Plague of Cats. 
My garden, like that of everybody else in this 
neighbourhood, is very much infested with cats. 
Can any means be devised to keep them out? 
(T. Wallis.) 
There are several very effective methods of 
keeping cats out by using wire netting on the top 
of the garden wall or fence. One method is to 
fasten the lower portion of the wire netting and 
leave the upper end loose, so that it would be 
too unsteady for any cat to struggle over it if 
properly fixed up. Another plan is to lay the 
wire netting along the top of the wall, so that 
one edge could hang ocer one side and the other 
edge hang into the other garden. This would be 
impracticable, however, if your neighbour objected , 
to wire netting overhanging his garden. Another 
excellent expedient is to fit up short supporting 
pillars on the top of the wall in which a kind of 
frame work roller is supported on a pivot. This 
roller might consist of a piece of board at either 
end on which cross pieces of a good length might 
be nailed, so that at least four lathes of wood 
would project from this roller-like machine. The 
cats will spring for this roller in the usual way, 
but being merely hung on pivots, it will turn and 
let the cats drop. Another portion of the roller 
will turn round, and the process may be re¬ 
peated, but the cats will be foiled, provided you 
make your rollers to turn easily upon their 
axes when an animal the weight of a cat 
attempts to alight on them.

Large Flowered Single Rose. 
Would you kindly name in your next issue 
hall a dozen Roses with large single flowers, of 
which I am very fond? (F. Wilson.) 
Two fine white varieties are Rosa macrantha 
and R. 4 ha. The flowers of R. Andersoni are 
quite as large as the above but of a beautiful 
pink. Paul’s Carmine Pillar is a single Rose, the 
name of which indicates the colour. Another 
fine white, producing large clusters of flowers, is 
R. moschata himalayica. There are several 
varieties of R. rugosa, including the ordinary or 
rose-coloured type, and the white one R. r. alba. 
The above will furnish you with a considerable 
amount of variety.

Rare Flowering Plant. —In the village of 
Longforgan, near Dundee, which is famous 
for its beautiful cottage gardens, a magnifi¬ 
cent specimen of Yucca recurvifolia is now in 
full bloom. The plant carries 650 separate 
blooms, which rise spike above spike in re¬ 
markable beauty, each drooping flower being 
nearly as large as a Tulip, and of a creamy 
white colour.
