REPOTTING. 



The indication that a plant needs repotting into a size 

 larger pot is known by knocking it out of the pot, by 

 giving a smart rap on the edge of a board, just as is done 

 in taking a form of jelly out of a mould. If the 

 roots have become matted on the outer surface of the 

 ball of earth, then it is in a condition to require a larger 

 sized pot. For the soil to use in potting, that recom- 

 mended for window boxes will answer equally well for 

 plants in pots. We are often asked if saucers should be 

 used to stand pots in. As a matter of keeping the place 

 clean where the plants stand, it is a necessity ; but the 

 saucers should never be filled with water, unless when 

 sub-aquatic plants are grown, such as Agapanthus, Callas, 

 Hyacinths, Tradescantias, or other plants of similar char- 

 acter. The best temperature for parlor plants is about 

 55 at night, which may be increased to 10 or 15 

 degrees higher during the day. 



ASPECT. 



The best aspect for plants grown in rooms is east or 

 southeast, south or southwest, but never north. It is 

 necessary, once in eight or ten days, to turn the plants, 

 so that each side gets an equal share of light, else the 

 plants will get lop-sided. If plants drop their leaves, or 

 the leaves become yellow, it is usually owing to one of 

 two causes : either that the soil is too wet or too dry. 

 Either condition will destroy the small rootlets, which is 

 indicated by the condition of the leaves. There is usually 

 more injury done from the plants being too wet than too 

 dry.
