GARDENING CALENDAR FOR MAY.

mencing to flower in a light and airy situation, 
in order to have the flowers stout and well 
coloured. Give them manure water occa- 
sionally. 
Gompholobiums, and similar creepers, must 
be regularly tied as they advance, or they 
soon look bad. Some of them will be in flower ; 
shade them, and water carefully. 
Haworthias, Apicras, &c, should be kept 
in a warm place near the glass, and should be 
incited to strong and early growth, in order 
to have the hot season to ripen in. Water 
regularly and rather freely. 
Helichrysums will be coming into bloom ; 
keep them near the light in an airy place, and 
water regularly and thoroughly, but not too 
often. 
Leschenaultias. — Shift free growing and 
young plants, shading and keeping them close 
at first ; water with great circumspection, as 
they are very liable to damp at this stage. 
Lilium jaj)onicum (Japan lily). — Shift 
if necessary, using large pots and rough 
compost. Water abundantly, and keep them 
in an airy place, where they will not be 
drawn. 
Mignonette. — Propagate the tree variety, 
either by cuttings or seeds, and train them to 
a single stem ; when potted off" keep them in 
an airy situation ; they will be found very 
useful in autumn and winter. 
Nero Holland plants, as acacias, hoveas, 
bossiasas, &c. — Shift, if not already done, and 
tie up and regulate the young shoots as they 
advance. Water carefully but plentifully, for 
if the drainage is efficient no danger can well 
occur to healthy plants. 
Orange trees. — Gradually harden those 
which are to be placed out of doors during 
summer by admitting a free circulation of air 
to them, and by not watering to so great an 
extent as would be proper for those retained 
under glass. The latter should be well en- 
couraged in their growth by liquid manure, 
syringing, and shutting up the house rather 
early in the afternoon. Attend to the regu- 
lation of the head by stopping or cutting out 
misplaced shoots. 
Oxalis. — Keep these near the glass, and in 
a free circulation of air, and supply them 
liberally with water through the flowering 
season, and until the leaves are matured ; then 
gradually lessen the quantity. 
Pelargoniums. — Shade those which are 
coming into flower ; water freely, using ma- 
nure-water about once a week ; keep them 
free from insects and dirt of every sort. Those 
from which seed is wanted should be placed 
by themselves, and the flowers should be care- 
fully guarded from bees, who will cut a hole 
through the unexpanded petals to reach the 
nectar in the flower tube, thus spoiling the 
flower, and most likely at the same time im- 
pregnating the stigma. 
Primulas. — Keep the young plants shifted 
as they fill their pots ; but it is better not to 
commence so early with them. Look to the 
old roots of the double varieties ; put them in 
a cool shady place, and water carefully. 
Proteas, Banhsias, Dryandras, &c, should 
be encouraged in their growth by a good 
watering whenever they appear dry. It is 
advisable not to set them out of doors until 
they have nearly completed their growth, 
when they should be well staked, to prevent 
their being blown about. 
Rhododendrons. — Keep them thoroughly 
watered while growing, and be sure that the 
ball is thoroughly soaked ; they should have 
plenty of air, especially when their growth is 
completed, but their tender foliage should not 
be exposed to the direct rays of the sun. 
Roses. — Guard diligently against insects ; 
hand-pick for the " worm i' the bud," and 
use the usual remedies against others. Thin 
out the weaker branches, and stop and tie up 
the climbing ones where necessary. 
Salvias.- — Shift, and stop and tie up these, 
keeping them close, and shading for a few days; 
water freely, and keep them, when established, 
in a warm but airy situation. 
Siapelias. — Shift, if not already done : tie 
up the stronger, or longer growing sorts ; and 
expose them to the most intense light, when a 
little established. Water rather freely as they 
advance in growth. 
Tropceolums. — Grow these in the most airy 
part of the house, and near the glass, except 
when in flower, when they should be shaded : 
they want training almost every day. Guard 
them carefully from slugs and snails, and also 
from the green cabbage caterpillar, which will 
sometimes commit great havoc on them : keep 
them rather moist than otherwise. 
THE CONSERVATORY. 
Temperature. — From 60 to 70 degs. by 
day, and about 50 degs. at night. This struc- 
ture being more for the display of flowers 
brought forward in other houses than for the 
growth of them, it is requisite to keep the 
temperature somewhat low in proportion to 
the advance of the season. Shade is now 
indispensable, and will be in almost constant 
use. 
Ventilation. — Give air freely, but on windy 
days do not open the sashes on the windward 
side of the house. Leave more or less air on 
all night. 
Watering. — Be careful in applying water 
to the roots of plants brought from warmer 
houses; those from similar or colder houses 
will require a liberal supply. The paths 
should be kept as damp as can well be managed
