264 GREEN-HOUSE — INSECTS. [April. 
Dutch Roots. All the species and varieties of these that 
have been kept in the green-house during the winter will 
now be done flowering ; the water should be withdrawn 
gradually from them ; and then the pots turned on their 
sides to ripen the bulbs. Or, a superior method is, where 
there is the convenience of a garden, to select a bed not 
much exposed. Turn the balls out of the pots and plant 
them ; the roots will ripen better this way than any other. 
Have them correctly marked, that no error may take place. 
They can be lifted with the other garden bulbs. 
FLOWERING PLANTS. 
The best situation for most plants, while in flower, is 
where they are shaded from the sun, and fully exposed to 
the air. Primroses, both European and Chinese, flower 
best, and the colours are finest, where the plants are in the 
front of the house and entirely shaded. The Chinese Azaleas 
and Rhododendrons require, while in flower, a similar situa- 
tion. Have all the shoots tied naturally to neat rods, and 
keep them clear from others by elevating them on empty 
pots, or any other substitute. See that there are no insects 
upon them; for they make a miserable contrast with flowers. 
The Cdlla AEtMopica should stand in water when in bloom, 
and even before flowering they will be much strengthened 
by it. 
INSECTS. 
Insects will, on some plants, be very perplexing. The 
weather may admit of those that are infected to be taker 
out of doors, and put into a frame in any way that is most 
convenient. Fumigating them about fifteen minutes, if the 
day is calm, will be sufficient; but if windy, they will take 
half an hour. When done, syringe them well, and put 
them in their respective situations. By the above method, 
the house will not be made disagreeable with the fumes of 
tobacco. 
Tie up neatly all the climbing plants. Keep those that 
are running up the rafters of the house close to the longi-
