GREENHOUSE PLANTS FROM SEEDS 57 



from actual frost. If they have to go into an ordinary 

 greenhouse, keep them as far removed from the hot 

 water pipes as possible. Green fly is very troublesome 

 and must be kept off them at all costs. The leaves are 

 soft and readily injured by insecticides, so that it is 

 important to vaporise lightly and often with one of the 

 Nicotine preparations. 



Cineraria. Sow seeds any time during May in pans 

 of light soil placed in a cool, shady corner of a garden 

 frame. Shade must be given at all times through the 

 summer, and the garden frame placed at the back of 

 a wall with a northern aspect is best for them until 

 winter frosts will allow of it no longer. Two things 

 on which one may be quite emphatic, are that the plants 

 are tender and easily injured by frost, and on the other 

 hand that they do not like artificial heat, though they 

 must have it at times to keep them safe. When the seed- 

 lings are large enough to handle, prick them off a couple 

 of inches apart into other pans, the soil for which may 

 be half loam and one-sixth each of decayed manure, leaf 

 mould and sand. Before they become crowded, pot off 

 singly, using good drainage, as they like plenty of water ; 

 never letting them become pot-bound until the final 

 size of pot is reached. Plants in six-inch to eight-inch 

 pots are the handiest, and they should be well established 

 in these by the end of September. They will be much 

 benefited by night dews during summer, and the frame 

 lights should be drawn off every evening when the 

 weather is fine and calm. A cool ashes bottom is good 

 for them in the frames, and when moved to the green- 

 house they should be kept well away from the pipes. 

 Cinerarias are very subject to green fly and should be 

 frequently treated as advised for Calceolarias. 



Campanula pyramidalis. This, the tall growing Chimney 

 Campanula, is really perennial, but for ordinary purposes 

 is best sown yearly. Seeds sown in April or May do
