530 THE HOT-HOUSE. [SEPT. 



into the green-bouse while this work is going on, and these should 

 be effectually washed and cleaned, if infested with these insects, 

 before their being replaced. 



This cleansing, fumigating, &c., will destroy most, if not all, of 

 the lurking insects which have taken shelter in the various parts of 

 the house, and which, by and by, if not destroyed, would sally forth 

 and make a formidable and, perhaps, destructive attack upon your 

 plants ; every timely precaution ought to be taken to keep the house 

 clean and sweet, and the plants free from vermin. 



TAKING IN THE PLANTS. 



The more tender kinds of hot-house exotics which are arranged out 

 of doors should, in the middle States, be taken into the green-house 

 about the tenth of this month, and the others successively, according 

 to their respective degrees of tenderness, so that the whole collection 

 may be in by the eighteenth or twentieth thereof, or a few days 

 earlier should the weather happen to be cold. Here they are to re- 

 main, closing the windows at night and giving them all the air pos- 

 sible on warm and mild days, till towards the end of the month, or 

 sooner if you have the hot-house ready for their reception. 



"When you have everything in readiness dress the plants by pick- 

 ing off all decayed leaves, and especially those which are annoyed 

 with insects, cut away all awkward and ill-placed branches, give each 

 pot a fresh top dressing of suitable compost, and place the smallest 

 in front and the tallest behind, on the shelves of the stage. The 

 succulent sorts may be set on shelves arranged over the flues, &c. 



Now the plants being in order and placed in their winter quarters, 

 it will be of much importance to give them plenty of air every favor- 

 able day by sliding open the upright glasses, and also the roof-lights 

 if necessary, in order to prevent their being drawn up too tender 

 before winter, for the fresh bottom heat will give new action to the 

 plants, and render abundance of air the more necessary; observe, 

 however, to close the lights every evening when the house is tolerably 

 warm, and to open them as early in the morning as you find the 

 thermometer up to 60 degrees of Fahrenheit. 



It is scarcely necessary to mention that every plant must have a 

 due supply of water, from time to time, according to its nature and 

 necessity. 



PINE-APPLE. 



Succession pine plants which are expected to produce fruit next 

 year may, in the first week of this month, if omitted in July and 

 August, be shifted as directed j but on no account should this be 

 delayed longer. Where it has been done in the preceding months, 

 and at that time no fresh tan added, it will now be necessary to exa- 

 mine the heat of the bark-bed in the succession house, wherein the 

 plants in general are plunged, and if you find it very weak fork up 

 the tan to the bottom, and plunge in the pots again immediately to 

 their rims.
