It is important to realise that the water which soaks side- 
ways also soaks downwards, and so never reaches the surface 
in the middle of the row. In the case of seeds and seedlings, 
it may be necessary, therefore, during a very dry spell, to lift 
the P.M.Gs. and water the ground underneath them; this is 
an exception to the general rule. a 
(1) Movability 
Chase Continuous P.M.Gs. are so firmly made that they 
can easily be moved about. Though they take to pieces easily 
and quickly they need never be dismembered because they 
can always be in use Over some crop. 
(j) Planned cropping 
Some crops will grow under P.M.Gs. from start to finish, 
e.g. lettuces. 
Sometimes P.M.Gs. are used just to start plants off on their 
way and give them the necessary protection from birds, cold 
winds and rain. Thus the same P.M.Gs. can be used to cover 
successional sowings of any particular crop. ; 
(k) City gardening ; 
The P.M.G. is of prime importance to city gardeners, for 
it not only brings on the crops earlier and in better condition, 
but in the case of vegetable or delicate flowers the produce is 
protected from soot, smog, and other similar and undesirable 
contaminations. P.M.Gs. are essential for the city grower 
who takes a pride in producing nothing but the best. 
(1) Pests 
Many pests and diseases are far less troublesome under 
P:M.Gs. Some simply do not attack P.M.G.-grown crops.

CROPS OF THE HIGHEST QUALITY IN THE 
SHORTEST TIME. |
