THE GARDENING WORLD 
V. 
more refined of the two is T. minus, as it forms dwarf and 
bushy patches when subjected to cutting, quite unlike the long 
straggling shoots it usually produces. Anthemis nobilis, the 
ordinary Chamomile, holds on to the ground very closely when 
subjected to cutting, and its leaves exhale an agreeable 
aromatic odour when trodden upon. The Yarrow (Achillea 
Millefolium) also does well in short grass, and might be found 
useful. On cricket patches and bowling greens we think the 
Clovers should be avoided, however, as they are slippery, 
especially in wet weather. 
Cucumbers Diseased. (A Constant Reader.) 
Your Cucumbers are very badly affected with what is known 
as Cucumber blotch, caused by the fungus Cercospora bolleana, 
which works irreparable damage with the plants in a short 
time, rendering them, irseless. Some of the fruits you send us 
have already become completely rotten, and in others the fun¬ 
gus is eating its way into the fruit. In cases where the disease 
is not very bad, you should cut off everything affected by the 
fungus and burn it, to prevent the spreading of the spots to 
uninjured parts. The remedy advised is to dress with sulphide 
of potassium at the rate of 1 oz. to 2 gallons of water, at fairly 
frequent intervals. If the plants are very badly affected, the 
only resource is to clear out the Cucumbers and burn them. 
There can be little doubt that the wet character of the season 
has been greatly conducive to the spread of plant diseases, and 
especially in the case of plants with very soft tissues, such 
as leaves, growing stems, and fruits. In cold and ungenial 
seasons like the present, it would be advisable to be always 
on the look-out for ailments of this character, and to avoid them 
as much as possible, keeping the atmosphere of the house 
drier. A little more ventilation at times would be advantageous, 
even if it is necessary to employ a little more fire heat now 
and again, to keep up the requisite temperature. 
Origin of Perpetual Strawberries. (G. A. M.) 
The now well-known Strawberry St. Joseph was raised by 
the Abb6 Thivolet, of Chenoves (Saone et Loire). It was put 
into commerce by Messrs. Vilmorin, of Paris, in 1897. The 
Abbe also raised the larger variety named St. Antoine do 
Padoue. This was said to be the result of crossing St. Joseph 
and Royal Sovereign, which would account for the larger fruit 
and superior quality by comparison with the older one. This 
variety was also put into commerce by Messrs. Vilmorin in 
1899. Their continuous cropping qualities can best be kept 
up late in the season by the removal of all the flowers that 
make their appearance early in the year, when other varieties 
are obtainable, and of better quality. They thus reserve their 
strength for late fruiting. 
Plants for Walls. (T. W. H.) 
All walls will readily support various things when once you 
can get the plants established. This is best done by means 
of seeds, as a rule, and if done in the autumn, when the 
atmosphere is fairly moist and sufficiently warm, the seedlings 
will push their way into the crevices before the advent of 
winter. The best form of wall gardening, however, can be 
carried out if walls are built on purpose. Such walls need not 
be very solid, but contain spaces in which soil is freely used, or 
a thin double wall may be built and the hollow between entirely 
filled with suitable soil. Some soil could be placed between the 
layers of stones so as to form a continuous passage-way for the 
roots of plants to the wall within. In the case of larger plants 
it would be advantageous to leave a fairly wide opening, so that 
the plants would have ample room to develop and form large 
crowns, while the roots are in direct contact with a larger body 
of soil. In shady situations Ferns could be largely employed 
with fine effect, and most of our British species would be avail¬ 
able for this purpose, with the exception of the Bracken, the 
Maidenhair Fern, Moonwort, and Adder’s-tongue. All the 
Sedums and Sempervivums would be available. Saxifragas of 
the crustaceous type would be very suitable, and some of them 
even quite handsome, while all are of neat and pretty habit. 
Others that might be mentioned are Linaria Cymbalaria, L. pur¬ 
purea, Pinks, Carnations, Antirrhinums, Erinus alpinus, Wall¬ 
flowers, and various others that usually grow upon rocks or 
walls in the wild state. There are so many that might be 
employed for this purpose that it would be well to exercise your 
own judgment in making a selection. A little experience will 
also show you which things do best with you, so that you can 
multiply them or add other species of a similar habit. 
Strawberry-Raspberry. (Curious.) 
We heard of the story many years ago that the plant of this 
name was a hybrid between the Strawberry and Raspberry. 
u? We cons ^ er ; however, as a mere fiction, as the plant grows 
wdd on the mountains of Japan, and is merely a dwarf growing 
variety of Rubus rosaefolius. 
Clematis with Bare Stems. (A. J.) 
This is partly the result of letting the original stems run up 
from year to year unrestricted. You could help your plants in 
this respect by cutting them down to the ground in Alarch or 
even earlier. If the roots have been previously well established, 
the plants will throw up numerous suckers from the base, and 
will be well furnished throughout with leaves. Unless you do 
this every year, however, the Clematis is liable to get bare at 
the bottom. You should make a point, however, to always en¬ 
courage a few shoots annually from the base, and this would 
keep the plant well furnished throughout. The Clematis has a 
tendency to grow very strongly at the top, and very often these 
shoots are allowed to form a dense overhanging mass that keeps 
the light from the stems and foliage below. If you prevent this 
as far as possible by tying in the shoots in their proper places 
the lower branches and shoots will get a better share of light 
and retain their foliage better. 
Duration of Raspberry Plantation. (E, A. S.) 
The actual duration of a Raspberry plantation very much de¬ 
pends upon the soil, the situation, and the preparation of the 
soil previous to the formation of the plantation. The Rasp¬ 
berry roots near the surface, and is much benefited by annual 
additions of leaf mould or even well decayed manure, not so 
deep in the case of the latter as to prevent the soil from getting 
warmed and aerated, but just sufficient to form a good mulch 
and also help to feed the plants. You will see that the annual 
keeping of the plantation in good order has a good deal to do 
with the duration of the Raspberry stools. A limit cannot, 
however, be fixed in the matter of years, as it might vary from 
five to ten, fifteen, or twenty, according to circumstances, and 
you will have to make a fresh plantation when the old one 
becomes played out, taking care to have the new one sufficiently 
advanced to take the place of the old before uprooting it.
