Plants differ widely in their reaction to pruning and their 
ability to regenerate thereafter* 3ome kinds readily make new snoo ts 
even if most of, or all? the top growth has been cut away. Old and 
ailing plants can often be rejuvenated by drastic ^ pruning. 
Other plants resent severe pruning and nay be killed by it. 
When to prone is important as it el sects both the growth 
response and health of the plant* 
Garry out pruning to restrict shapes for hedges* 
Pruning tools must be razor sharp and clean cutting* Use a 
pruning saw for large cuts then clean and smooth the rough surface of 
the cut with a knife and protect if with a tree antiseptic such as 
white paint.

In pruning there arc four guiding principles which should be 
kept in mind. 
(1) Gut cleanly. f fhe living cells of the shoots are concen- 
trated in and about the greenish, slightly slimy area, called cenbium 
just inside the bark, fry not to damage these cells, as the healing 
of the cuts and the development of the growth depend on them* 
(2) Gut just above a Cal thy bud or node. It is hero that 
cembiun and growth cells are most concentrated and where tne energies 
of the plant will be diverted, o tart the cut op -osite to and level 
with the base of the bud and start it very slightly upwards to finish 
just above the bud. 
(3) ihe growth reaction will be strongest in the tcmm.nl and 
uppermost buds left after pruning. .Then pruning for now growth, make 
the cut above a bud facing the direction the new shoot is required to 
grow*
