GARDENING CALENDAR FOR MAY. 
to 70 degrees as the maximum, which will he 
sufficient for all forcing purposes. 
THE GREENHOUSE. 
Temperature. — From 55 to 60 degrees by 
day, and 45 degrees by night. 
Ventilation. — Give air freely, and leave 
some on all night when the weather will permit. 
Watering. — The supply of moisture must be 
liberally increased with the seasonal rise of 
temperature ; by this time the plants will 
probably need water daily ; the syringe may 
be used freely both morning and evening, so 
that any expanded blossoms are not wetted. 
Examine the roots especially of old or large 
specimens, and be well convinced that they are 
thoroughly soaked occasionally ; they will 
surfer less then if they are sometimes missed. 
Potting. — Continue to shift such plants as 
may require it, adapting the size of the pots to 
the habit of the plant, or the nature of the 
house or purpose for which it is wanted. Be 
very particular in the drainage of every pot, 
as on that alone more than on the soil will 
frequently depend the whole success of the 
plant. 
Soils. — Always keep the potting-shed well 
supplied with the different soils, and other 
materials necessary, as pots, stakes, tallies, 
matting, &c. A great deal of time may be 
thus saved, especially as regards tallies, which 
may be made and sorted ready for use in 
winter, or on wet days. 
Dressing. — Remove all dead leaves, flowers, 
or plants out of flower, as soon as they become 
faded ; tie up and stop the creepers where 
necessary; never allow them to interfere with 
other plants. 
Insects. — Use every means to keep down 
the various insects, whose numbers will become 
enormously increased as the weather grows 
warmer. 
Aloes, and similar plants, should be supplied 
with more water as they advance in growth, 
and should be kept warm and exposed to in- 
tense light. 
Agaves should be watered rather sparingly; 
they may be kept in the coldest part of the 
house to inure them for removal to their out- 
door stations by the middle or end of the 
month. 
Alstromerias. — Thin out the weaker shoots 
and support the others ; give a good shift if 
necessary, and keep them in a cool airy part 
of the house ; supply them freely with water. 
Annuals. — Shift such as require it, and 
stake and tie them as they advance ; water 
freely, as from the number and succulence of 
their leaves and roots they require a large 
amount of moisture when growing. 
Azaleas that have done flowering should be 
well watered, and placed in a warm house to 
perfect their growth. Any symptoms of the 
roots getting dry from the water not pene- 
trating the ball of earth, must be watched and 
attended to, or death will result. 
Calceolarias. — Shade those in flower; they 
require plenty of water ; use manure water 
occasionally. Keep them regularly tied as 
they advance, or they soon become unmanage- 
able ; stand them on an airy stage, near the 
glass. 
Camellias. — Keep them growing steadily ; 
water freely ; disbud or cut back in time, so 
as to form neat heads. They bear shade well, 
and may now and then be syringed. 
Cape Bulbs. — Some of the Gladioli will 
be in flower ; water freely, and let them have 
all the air and light possible, in order that the 
foliage may attain a proper development. 
Cephalotus j'ollicularis (New Holland 
pitcher-plant), requires a pan under the pot ; 
the glass over it may be elevated a little, but 
not for so long a time as to dry the plant too 
much. 
Cinerarias. — Propagate by parting the 
roots and potting them again; or bed them out 
in a moist shady border to be potted up in 
September. 
Chrysanthemums. — Part the old roots and 
repot them, or better, if not done before, turn 
them out in rows to grow to supply strong 
cuttings and layers later in the season; the 
first method will produce the largest and tallest, 
the second the neatest plants. 
Crassulas. — Several of these will be in 
bloom ; keep them rather cool to prolong their 
duration ; water sparingly ; when out of flower 
give them more heat and moisture, that they 
may grow freely. 
Cyclamens. — Some of the varieties may be 
kept in flower far into the summer by keeping 
the roots in a cool and shady place, and start- 
ing them at different periods. Water regu- 
larly such as are in bloom, but reduce the 
supply when the leaves show signs of matu- 
rity, and dry them gradually. 
Epacris. — Place in any airy but rather 
warm situation, and water regularly and 
copiously until they have completed their 
growth. 
Ericas. — Continue to shift as they display 
the necessity: remember that a heath once 
really dry at the root is lost ; therefore water 
thoroughly and abundantly, shading the grow- 
ing plants in bright sunshine, and allow no 
obstruction to the freest circulation of air. 
Keep the plants constantly stopped until the 
desired shape is attained, and syringe them on 
warm evenings. Propagate from the points 
of the young shoots as soon as they are long 
enough and firm enough for cuttings. 
Fuchsias. — Continue to stake and train them 
as they advance, placing those which are com-
