Either the one or the other of these circumstances 
is continually producing a greater influence on 
almost all the plants in our gardens than is thought 
of by most amateur cultivators. It is not uncommon 
to hear, even careful cultivators of floAvers, com- 
plain in regard to some of their favourite plants, 
that ^'They grow nicely for a year or two, and then 
they die.” Now, if a plant blossom twice in the 
same garden, the loss of it afterwards must be re- 
ferred to careless culture, unless it fall under the 
influence of unusually severe weather, a reason 
which can but rarely be legitimately advanced. 
Losses usually arise from the omission of necessary 
division, or propagation by other means. Young 
plants bear the vicissitudesofan uncongenial climate 
better than old ones ; and furthermore, our soil 
may not be rich in the species of nutriment required 
by some of the exotic plants which we cultivate, 
therefore fresh pasturage should be frequently given 
them. 
Although the Phlox pyramidalis is perfectly 
hardy, still, if it be left growing in one place more 
than a single year, it will decline in health ; and 
in many places, in three years, be altogether lost. 
The most successful mode of treatment is this ; 
take off some of the young shoots in September, 
with a little of the root attached, and plant them, 
singly, about six inches apart, in a light soil, giving 
them a little water occasionally, if the autumn be 
dry. In February or March they may be removed 
to the situations in which they are to flower. The 
success which will succeed this trifling attention, 
will amply repay the trouble bestowed on them.
