There are several pests to which the 
Carnation is subject, 'such as mildew, 
wireworm, eelworm, rust and green-fly, 
and sometimes red spider. To check mil¬ 
dew, dust with sulphur, and keep out all 
damp. Wireworm and eelworm can be 
enticed on to a piece of raw Potato or Car¬ 
rot placed near, and when captured by 
this means they can soon be destroyed. 
It is best to destroy all parts of the plant 
infested by rust, as there is no effectual 
cure. Red spider can be checked by 
syringing, and green-flv by means of 
fumigation. 
There are many varieties of winter 
flowering Carnations, but the following 
include some of the best: Enchantress, a 
splendid large bloom of flesh pink; Mrs. 
T. W. Lawson, very fine pink; Harlo- 
warden, beautiful dark crimson; Fair 
Maid, light rose pink, a charming flower; 
Glacier, a pure white of the best form; 
Flamingo, one of the best scarlets grown ; 
Rosalind, white marked pink ; Britannia, 
a lovely scarlet ; Lady Bountiful, pure 
white, very fragrant; Mrs. H. Burnett, 
charming form of flesh pink; The Pre¬ 
sident, fine crimson; and Mikado, large 
flower, heliotrope colour. These will 
make a splendid collection, and given 
cultural care, should make a fine show.

Rock Work in Front of 
Flower Borders. 
Rockwork can be used in the garden 
in various ways with charming effect, but 
in no way more effectively than as an 
edging to flower borders. This will be 
found much more attractive than the 
formal and troublesome Boxwood edging. 
As the spring is the best time in which 
to plant alpines and other rock plants I 
will describe for the benefit of others how 
I went to work, and if they follow my ex¬ 
ample and try a rockwork edging to one 
or more of their borders they will not re¬ 
gret necessary labour and expense. 
First of all mark off the extent of the 
border which is to be treated with the 
rockwork edging, and trench this edging 
two spits deep. Leave this for a w T eek or 
two to settle and in the meantime pre¬ 
pare a suitable soil to be used to form a 
mound one and a half feet in height 
along the margin of the border. 
After the soil has been placed in posi¬ 
tion and well firmed, planting can be at 
once commenced, as I approve of planting 
before the stones are placed in position. 
It should not be omitted, however, to put 
a small stake at the back of each plant, 
especially such plants as are entirely 
covered with soil, such as roots without 
foliage, or they will be smothered when 
the stones are laid down. The stones 
can be easily arranged around and about 
the plants after the planting has been 
done. It is important that the outline of 
the rockwork edging next the path or walk 
should be of irregular form and the stones 
judiciously and tastefully placed and 
varied as to size and position.

Coreopsis grandiflora. 
THE GARDENING WORLD. "3 
Goreopsis grandiflora. 
Although not by any means the tallest 
growing species of Coreopsis, this is one 
of,the finest on account of the large and 
rich golden-yellow colour of the flowers. 
Unfortunately it is not equally durable in 
all soils, and for that reason most growers 
of the present day make a point of sow¬ 
ing seeds every year, whether for garden 
decoration or for the purpose of getting 
cut flowers, for wdiich this species is in¬ 
valuable. Although it has a disadvantage 
in one respect, it has the advantage, al¬ 
though a perennial, of being raised from 
seeds and bloomed in the same year. 
That, of course, means early sowing — say, 
at once, as February is now making pro¬ 
gress. It could, of course, be sown earlier 
by those having convenience and some ex¬ 
perience in raising seeds early in the year. 
The conditions for seed raising are now 
much better than they were last month, 
but artificial heat will still be necessary. 
Those who have not the command of suffi¬ 
cient heat in a house could still raise this, 
and many other kinds of seeds, by making 
a hotbed. About 2 ft. in depth of manure 
would now work wonders in the raising of 
seeds, and by the time the hotbed has 
cooled down, cold frames would be quite 
sufficient for the accommodation of the 
seedlings. 
Coreopsis grandiflora, although really a 
perennial, usually dies out in heavy soils 
during the first winter after it has 
floored. By raising seedlings in the way 
we have indicated, a good stock of flower¬ 
ing plants can be raised, and few of the 
composite family, to which it belongs, are 
more refined in appearance than the 
flowers of this. Those who have no com¬ 
mand of fire heat, or a hotbed, can, of 
course, raise several species of annual 
Coreopsis by sowing them in the cpen 
garden at the beginning of April. The 
flowers of C. grandiflora are, however, 
much superior, that is, larger, and they 
are worthy of some little extra trouble 
in order to get a supply of cut flowers, 
than which few things are more handsome 
in vases during August and September. 
The seedlings should be transplanted 
into boxes as soon as they have made two 
rough leaves in order to keep them grow¬ 
ing. The soil in which they are raised 
sometimes gets sour by over-watering, and 
this transplanting puts them in contact 
immediately with fresh soil. By the time 
the seedlings have got well established
