THE OAR DEWING WORLD. 
until all danger of severe weather has passed away. The slate 
should be removed, however, in good time to allow the ground 
to receive the benefit of the. sun s rays and also get moistme, 
for that is necessary during the period of growth, especially if 
the weather is at all dry during spring. 
Name of Cantu a. 
We have a plant under the name of Cant-ua depen dens, but 
several gardener's contend that C. buxifolia is the correct name. 
Would you say which is the correct name? (A. E. AV.) 
The correct name is C. buxifolia, the other being a more recent 
name, and therefore incorrect. The plant has also been named 
Pei'iphragmos dependens. 
Acalypha sanderiana. 
I should be obliged for an opinion of how this plant should be 
treated after it gets too tall. Is it worth while growing on old 
plants by cutting them back after resting for a while ? (P. M.) 
You can treat the plants as you mention if you want strong 
specimens, but they never look so well as young plants, owing 
to the branches interfering with one another and preventing 
the drooping tassels from attaining their proper size. We have 
sometimes seen old plants allowed to grow a second year, when 
they branched out at the top, forming, as it were, standards with 
freedom for hanging their tassels all round the head. Even by 
this method, however, they do not attain the length and vigour 
which they do upon young plants. You might have some of 
them for the sake of variety, as they could be stood in a con¬ 
servatory amongst other plants when not in bloom. To get 
neat specimens of dwarf habit, the best plan is to take cuttings 
in spring every year, and grow them on in the same way as is 
done with various other winter and spring flowering plants. 
By so doing you can get vigorous single stems, and the tassels 
of scarlet flowers attain a great length under these conditions. 
Such plants are useful where taller specimens would be inad¬ 
missible. 
Propagating Portugal Laurel. 
Can you say whether I can propagate Cerasus hisitanioa, 
azorica by means of cuttings, and the best time to do it? 
(Cherry.) 
AVe think you can manage to propagate it by cuttings in pots 
of sandy soil in a pit with a gentle warmth towards the end of 
summer, when the young shoots are beginning to harden. Cut¬ 
tings could also be inserted in sandy loam and leaf mould in a 
cold frame in October. Make the soil rather firm, and insert 
the cuttings deeply. This variety of Portugal Laurel might be 
propagated by inserting the cuttings on a north aspect border 
in October, but if you have only a few cuttings to spare it would 
be safer to put them in a cold frame, as they would be kept 
moist about the base without letting them be soaked with 
wet and frozen alternately during the rooting process. There 
is another process, namely, by layering them, and it may be 
done in the open ground at the same time as Carnations, and 
much in the same way. The usual method of raising the ordi¬ 
nary form of Portugal Laurel is from seeds, the stones being 
sown or committed to the soil as soon as they are ripe, to 
prevent them getting dried up. If you have any seedlings raised 
in this way, you could propagate the Azorean variety by graft¬ 
ing it upon the seedlings. That could, of course, be done at 
the present time in the open ground or under glass, according 
to convenience. 
Eadishes Spoiled by Grubs. 
Some of my early Radishes in a cold frame have been bored 
into by some grub, and rendered useless. Can you say what the 
grub might be, and how I can get rid of it? (H. C.) 
The grub is no doubt that of Anthomyia radicum, which 
bores into the roots of Radishes, Turnips, and sometimes other 
members of the Brassica family. It is difficult to deal with 
this pest in any wholesale manner, as the grub is not detected 
until it has done the mischief. The only thing you can do is 
to guard against future attack by destroying, by burning, every 
Radish that is bored into. Another year, when growing early 
Radishes, you should be careful to get some fresh soil from 
a source where none of the Brassica tribe have been grown re¬ 
cently. It is just possible that the damage might have been 
done by the Cabbage Gall Weevil (Ceutorrhynclius sulcicollis) 
As a rule, however, the grubs of this weexil do not penetrate 
deeply, but make a gall or swelling on the surface. AATien, 
however, they pierce the root low down, the whole root is prac¬ 
tically affected, or, if they attack the “atable portion while it 
is stiil young, n uch about the same effect would be produced. 
The same remedy would apply in this case as in the last, 
namely, to destroy the roots and grubs before the latter have 
time to change into the perfect state and commence their 
depredations on other crops of the same or a similar kind. 
Making a Carrot Bed. 
Our ground is very much infested with the Carrot Fly Maggot, 
and we grow our main crop in the fields. 1 want to grow a late 
crop in the garden, and, if possible, to keep the roots clean. I 
have heard that the ground may receive special preparation. 
The ground here is a rich black soil. If you can say how I can 
make it suitable for Carrots I should be much obliged. ( . C. •) 
The natural soil should be taken out to the required depth 
and if you want a late crop the snort horn varieties would 
be the most suitable. About 18 in. of soil would, therefore, be 
deep enough for any of this class. The bottom of the bed 
should also be well' loosened up, as you could grow deeper- 
rooted kinds in the soil in after years. Make up a compost 
consisting of fresh loam obtained from some field or pasture, 
mixing it with plenty of sand and wood ashes. Some growers 
use peat for mixing the soil, with good results. Any light, ric i 
and sandy compost will, however, suit, them, but it should all 
be fresh. While you are about it, it. would be a good plan 
to sift the whole of the compost so as to get rid of all stones, 
lumps of earth, etc. A very fine soil enables the Carrots to 
make straight and clean roots. Usually fresh material that 
has been made up in this way enables Carrots to be 
grown on the same ground year after yeai% without being much 
interfered with by the maggot. Carrots tnat are able to grow 
away rapidly from the first are not as likely to be injured as 
those which drag along slowly in their early stages.
