Pruning.— Being terminal plants, they seldom re¬ 
quire pruning, as it prevents their flowering until 
their next growth. When they have grown too tall, 
the best way is to head them down, which should be 
done early in Spring, or at the time of shifting. In 
this case, cut them down as low as you wish, for the 
inert buds will grow out from all parts of the stems, 
and they will make fine bushy plants by the Fall, and 
flower freely the next season. 
They are subject to the white scaly insect under 
their leaves and upon their stems, which should be 
cleared away whenever they appear, by cutting off the 
most affected leaves, and washing the remaining ones 
as well as the stems, with soap and water.
