Tuber of Celeriac full of specks .—L H.: The 
tubers of your Celeriac are badly infested with the 
Celery stem Fly (Piophila Apii). The maggot of 
the fly is legless, cylindrical, yellowish-white, and 
eats its way into the fleshy part, forming worm- 
eaten tunnels or passages, which become rusty-red 
around the gnawed surfaces and for a little way 
inwards, the rest of the tuber being clean and white 
so that there is no fungus in the same. The injury 
is entirely confined to the worm holes which are 
rather numerous, and quite spoil the tubers for table 
use. Unfortunately the remedies are few. and 
though effective enough they must be conducted at 
great loss. The chief remedy is to destroy all the 
worm-eaten tubers by burning them or burying them 
about 3 ft. deep, so that the flies when they are full 
fed and have passed through the pupa stage, will be 
unab’e to reach the surface when they reach the 
perfect stage in May. The tubers can be burnt in 
the stokehole furnace, or if very numerous they may 
be placed on a heap of prunings and other garden 
rubbish that is being burned. It is useless to throw 
the tubers on the rubbish heap, as the flies will pass 
through their various stages and emerge in the 
winged state as if nothing had happened. This work 
of destruction should commence as soon as you 
begin to dig up the tubers for use, and the last of 
them destroyed by the beginning of March. It 
would be a good plan to grow your Celery and 
Celeriac in a field at some distance from the garden 
for a few years, if you have such a field at com¬ 
mand. 
To Flower Gladioli in July.— L. H. : The system 
of pottmg up the corms early, as you mention, is 
practised to some extent, but it takes up a good deal 
of time and space, as you say. The plan ot putting 
the corms into boxes, which you suggest, is quite 
feasible and workable, as we have practised it our¬ 
selves with perfect success, and bloomed the plants 
much earlier than those planted in the open during 
March and April Even if you were to plant earlier 
the low temperature as a rule would prevent the 
corms from starting into growth. Get some boxes 
about 3 in. or 4 in deep inside, and over the bottom 
spread a layer of old spent Mushroom dung and 
partly decayed leaves mixed. Over this lay the 
corms with the pr per side uppermost, and in lines 
about 3 in. apart each way. Tnen cover them up 
with a mixture or compost consisting of fibrous loam, 
rough leaf mould and sand, pressing it down rather 
firmly This can be done during the first half of 
March, and the boxes stood on the borders of a 
viDery at work. Stand them as near tne glass as 
possible to prevent the leaves becoming drawn 
when they come through the soil. About the 
middle of April they should have made considerable 
growth, when you should transfer the boxes to cold 
frames, keeping them close for a time until the foliage 
gets hardened, when more air may be given, and 
sufficient water to keep the soil moist. From the 
mirdle to the end of May, according to the state of 
the weather, they may be planted in the open ground 
and the flower stems staked as soon as they begin to 
push out from amongst the leaves, doing it neatly. 
In your district, if not too elevated, they should 
commence blooming in July. 
Cultural Treatment of Calla hastata.— A.D.W.: 
The cultmal treatment required by this plant is 
Similar tc that of Richardia aethiopica, better known 
as the Arum Lily, Arum plant, Lily of the Nile, 
Calla aethiopica and R'cbardta africana. The true 
name of your plant is Richardia hastata. After it 
has flowered the leaves will gradually begin to turn 
yellow and die away. When this takes place,gradually 
withhold wa ! er until quite at rest when water may 
be withheld till growth is recommencing when the 
plant or plants should immediately be repotted in a 
compost of good fibrous loam, leaf mould and a little 
weU decayed cow manure. Add sufficient sand to 
make the whole porous and open. Also give good 
drainage to allow water to pass freely away as a good 
deal will be required when growth is being made. 
Do not give much water, however, till grovth is 
gett ng vigorous. The precise time when the foliage 
may die down and the plants be at rest will depend 
upon the time they make their growth and the tem¬ 
perature given. From 35 P to 50° will be quite high 
enough in winter, and nearer the former than the 
latter figure. Water abundantly in summer when in 
full growth. When repotting, the suckers should be 
taken off and grown separately in smaller pots so as 
to give more room for the perfect development of 
flowering crowns. Pot rather firmly. 
Caterpillars on Camellias — W. B. G. : The 
caterpillar you send is one of the Noctuidae, a very 
large group of night flying moths which greatly 
resemble one aco her in the perfect or imago state, 
and are very difficult to distinguish. This being so 
it would be more difficult 10 determine the creature 
in the caterpillar state, as they are all brown or gray 
and variously marked with similar dull colours. 
Many of them infest a great variety of garden plants; 
in fact, nothing seems to come amiss to many of 
them. The plan adopted by your friend is the best 
that can be done under the circumstances. Many of 
these brown caterpillars hide in the soil by day and 
come out by night to prey upon the plants. A good 
plan, where the soil is loose, would be to frequently 
rake it and then beat it smooth with a spade, so that 
any holes made by the caterpillars could be 
detected and the culprits caught. You might also 
tie a piece of cotton wadding, rough side outwards, 
round the base of the stem of each Camellia tree, so 
as to prevent the caterpillars from crawliag up by 
night. This latter method, we think, would be the 
most effective of any while any buds or flowers still 
remain upon the bushes. 
Genista andreana from Seed.— -B. M. : The pro¬ 
per name for the plant is not Genista, but Cytisus 
scoparius andreanus, it being a colour variety of the 
common Broom. Your best plan is to sow the seeds in 
pots of light soil and stand them in a cold frame to 
germinate. After they have made a season’s growth 
you may plant them out in nursery lines in the open, 
where they may stand till they reach flowering size. 
You will then see which of them are true to the 
parent, and mark them for preservation while in 
bloom. You may then dispose of the yellow ones as 
you feel inclined, but retain those with crimson 
wings to the flower.
