Great care should be taken to keep the snails 
from it, as it is one of those plants to which 
slugs and snails are very partial, and the 
slightest neglect exposes it to great danger of 
being doomed in a single night when it is 
in a young state. A protection of zinc may be 
made in the shape of a hoop, say 3in. deep ; 
if this is placed round the plant it will 
prevent any slugs or snails from getting near. 
This is the only safeguard I have found 
against them. Of course this can be removed 
when the plant gains strength. We have 
a plant growing here which has been in the 
same place for thirteen or fourteen years, and 
looks as healthy and well as ever. It had no 
special care whatever, except the zinc hoop 
which is placed round the plant. I have 
regularly taken five and six cuttings every 
year from it. It is planted on the north 
side of a large Cupressus hedge. A top- 
dressing of leaf-mould and sand is given every 
year.
