264 GKEEN-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 now be done flowering; the water should be withdrawn 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 colors 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 uEthioj)ica 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 taken 

 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 sufiicient; biit 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-
