by taking out a trench 3 ft. to 4 ft. distant from the trunk 
and working towards the latter with a garden fork, severing 
extra strong roots with a knife, working well under the ball 
of roots, as it is often, here where the mischief is to he found. 
Mix back with the old soil a little wood ashes and lime or old 
mo it ar rubble of some kind, and as filling-in, goes on make 
the same quite firm by treading; and should the tree show 
signs of drooping its foliage keep it syringed and lightly 
shaded for a week. In a month’s time trees may be trans¬ 
planted if extra wood isi being made. .T. Mayne.

The Stove and Greenhouse. 
Richardia africana —There are but few greenhouse flowering 
plants more popular than the Arum Lily, and to ensure having 
an abundance of medium-sized pure white blossoms early in 
winter and onwards, the plants should have been duly ripened 
by withholding water and placing them either in the open or 
in a sunny frame or glasshouse. Plants thus treated will now 
be ready for repotting. Assuming that, no water has reached 
them for some time, the soil will have become baked, and a 
copious wa,tiering may be given a day or two before they are 
repotted. The pots I us© are 6-inch, and only one large conn 
is placed in the centre of each, but it may suit some growers 
to place two or three in a larger pot. Nearly all the old soil 
should be shaken out, and remove all small conns that sur¬ 
round the larger ones. The best of these may be potted up 
several in a pot. fen- growing on to increase the stock. A 
suitable compost consists of two parts loam and one each of 
leaf-soil and decayed manure, adding plenty of road or river 
sand and a sprinkling of chaired garden refuse and bone-meal. 
The top. of the oorm should be left just visible, as was advised 
for Laohenalias. Another method of growing this Lily is to 
plant out in trenches in summer and lifting them for repotting 
in autumn. Good results doubtless may follow this system ; 
indeed, I used formerly to practise it. myself, but for all¬ 
round results the, ripening off method is far preferable. The 
fresh-potted conns may be placed in a. frame and afforded a 
good watering. A good syringing twice daily will start them 
into growth quickly, and should the weather be very hot a 
light, shade: should be given for a few hours 1 in the middle of 
the day, and the frame closed early in, the afternoon,. Remove 
to, the greenhouse when the nights become frosty. 
Euphorbias. —Plants that have been growing in cold pits 
or frames should soon be removed to a structure where a, little 
fire-heat can be turned on at nights, but avoid using it too 
freely, or the sudden change will cause the lower leaves to, 
turn, yellow, and the growth made will be sappy. Keep near 
to the roof-glass and admit both top and front air to the 
structure on all favourable occasions. Apply well-diluted 
sheep, or cow liquid manure once or twice a week, and alternate 
applications! of weak guano water will a-ls-o assist to build up 
robust plants that will produce large and highly-coloured bracts 
at the proper time. 
Tea Roses.- —Those who are in the fortunate position of 
having a structure set, apart, for Roses can without much diffi¬ 
culty maintain a good supply of fragrant blossoms for several 
months in the year. Assuming that- quantities have been pro¬ 
duced throughout, the summer, they will now be past their 
best, if not actually devoid of flowers'. I advise thinning out a, 
good portion of the green spray-growth, retaining the strongest 
and best-ripened wood. Shorten some of this back where 
crowded, and tie neatly to the trellis. If the plants are in a 
restricted bolder a, little of the old soil may be removed with 
a hand-fork, replacing it with new loamy soil with which is 
incorporated a little bone-meal, decayed manure and wood 
ashes. Apply water liberally, and syringe twice daily, closing 
up early in the afternoon and turning on a, little fire-heat at 
nights. New growth and flowers will be produced in a very 
short time, and will continue right on through the autumn 
months. Plants in, pots may have the unripe wood shortened 
back and placed in a sunny spot in, the open ] these will give 
a, good account of themselves if partially rested and potted up 
early in the new year for early forcing. 
Climbers. —All stove and greenhouse climbing plants should 
have the growths thinned out at this time, in order to allow 
full air and light to, play about the remaining wood to ripen 
it. Those plants that, have ceased flowering may be somewhat 
severely dealt, with, whilst others' should have only the weakest 
growths pruned back at this time. The cultivator will, of 
course, be guided by the vigour and nature of the individual 
climbers as to how much to cut away now. 
Pits and Frames. —No time should be lost, in painting, 
glazing, and repairing any of these' requiring it before bad 
weather sets in ; moreover, they can, best, be, spared a,t this time 
than later on, when so many tender plants now in the open will 
need their protection. Too often, these indispensable adjuncts 
of the garden do not receive that attention in, this respect that 
they should, consequently they soon become dilapidated. If 
possible, they should receive a coat or two, of paint every year 
or two; they will then last for many years, K. M. 
Among the Orchids. 
Dendrobium formosum giganteum. Where this desirable 
species can, be induced to grow satisfactorily, it proves to be 
one of the most useful among late summer and early autumn 
flowering Orchids. If placed in, a house where the atmosphere 
is drier than, that usually maintained in the ordinary stove 
honsa, after the flower-buds have fully expanded, they last a 
long time in perfection,, and are useful for exhibition or for 
cut-flower purposes, especially where there is a demand for cut 
white flowers. Unfortunately, it belongs to a class, that cannot 
be called an easy plant to maintain in the normal vigour and 
the robust characteristics found in imported plants. This is 
no doubt partly caused by a, want of convenience in many 
gardens, to ensure the proper facilities necessary for the cul¬ 
tivation of the plants. Where a, house, can be set aside for 
the cultivation of Dendrobiumsi and the plants can be pro¬ 
vided with ample light, which enables them to properly mature 
their pseudo-bulbs, a difficulty will be almost sure to arise, 
and although they may be satisfactory and produce good re¬ 
sults for a season or two, after importing, they will generally 
deteriorate and ultimately are lost altogether. 
Where there are facilities for fruit forcing, especially ,a, Fig 
house where the Figs are grown in, pots and the roof is screened 
with little or' no shading whatever, here in the hot, humid 
atmosphere during the hottest months, of the year they make 
their growth far more satisfactorily than is found toi be the 
case in the most, up-to-date erected ’Orchid house. During the 
resting season cooler and drier conditions must be given. From 
the above it will be ,apparent that the writer is satisfied of the 
well-nigh impossibility of inducing this species to continue in 
vigorous health unless a very light position as well as a warm 
one can, be provided. The repotting is best done when start¬ 
ing the plants into growth in: the early spring, but where good 
material is used in the potting compost, the plants will n,ot 
require repotting very often, but the surface moss dies in the 
resting season, and therefore top-dressing is an, annual re¬ 
quirement. 
Importation® arrive in the spring, and they are then pro¬ 
cured for a moderate outlay. It is more desirable to secure 
imported plants than, to have to deal with established or semi- 
established plants. A change in, the conditions: of culture or 
the least check is undesirable. 
Laelia monophylla. —The so-called one-flowered Laelia, a 
native of Jamaica,, isi probably the smallest in structure of the 
genus. Nevertheless, it is a charmina Orchid, and under cul¬ 
tivation where the plants are induced to thrive, well, the nor¬ 
mally one-flowered scape produces two of its brilliant scarlet- 
flowers. It is somewhat of a strange plant to succeed with 
under different conditions. In, the south of England it thriyeg
