THE GARDENING WORLD. 
July 11, 1905. 
if you grow them in boxes in a cool frame, and then transplant 
them as soon as they are large enough into other boxes or a frame 
By pursuing this method the plants will be of fair size by next 
spring but probably very few of them would bloom. Another 
year in the open ground, however, would make large plants ol 
them, and they could be potted up in early spring, so that you 
could transfer them to the greenhouse or elsewhere you may want 
them.

We have your letter before us, and are making inquiries. 
Propagating Pyrethrums. (D. M- Wood.) 
You can lift the old plants in the autumn, pull them into 
single crowns, and pot them singly. If these pots are piunge. 
m a'cold frame for the winter the plants will make early growth, 
and you could protect them better from slugs than if they were 
put out in the open at once. Another plan is to wait till Marc i, 
and then divide the plants by hand into moderate-sized pieces 
planting them in their permanent positions. I ie\ w 1 
scarcely be so well established perhaps, nor grow so readily as 
plants'taken out of pots, nor should they be broken into such 
small pieces, unless you intend establishing them m pots after¬ 
wards.*^ Pulling them to pieces by hand is better than using 
a knife even, as you are liable to cut many of the roots. A spade 
should never be used in dividing Pyrethrums.
