March.'] GREEN-HOUSE. 193 



OF CLEANING, &c. 



If any of the plants require cleaning, either by fumigation 

 or otherwise, let it be done before the young foliage appears, 

 according to the directions heretofore given. Likewise tie 

 neatly all that require it, clean and top-dress those that will 

 not be shifted, having every plant, and all in the green- 

 house, in perfect order before the throng of spring com- 

 mences. The weather will now admit, in very fine mornings, 

 of the plants being syringed, which may be done between 

 seven and eight o'clock ; and the path or pavement should 

 be washed out once a-week, which is a great improvement to 

 the appearance of the whole interior. 



In winter, when any glass is broken it should be imme- 

 diately mended. Broken glass in cold nights causes a very 

 destructive current of air. It should always be made water- 

 tight, for if the drops fall into the pots upon the roots, they 

 will frequently prove fatal to the plants ; therefore care ought 

 to be taken during rain to remove those that stand in any 

 manner exposed. 



MARCH. 



The plants in this compartment will begin to assume a 

 different aspect, and air must be admitted every day if practi- 

 cable, giving large portions in sunshine by the sashes regularly 

 over all the house, opening those of the front a little, and 

 likewise the doors in fine mild days. To perform this 

 judiciously, give a little about eight or nine o'clock, more at 

 ten, and the whole from eleven till twelve o'clock, shutting 

 again by degrees. 



Fire heat will now be dispensed with, but in frosty nights 

 have the shutters on about sundown. The sun is now power- 

 ful, and the house can be early shut up in the afternoon, and 

 will gain as much natural heat as will keep up the required 

 temperature, viz., 36° to 45°. l^erhaps there may be un-
