4: Lay brickbats
having taken care of the above factors, you are now ready
to make a terrace garden on your own.
spread a layer of brick bats (totally burnt bricks) of approx.
2" - 4" evenly on the terrace. The brick bats
are used to facilitate the drainage of water. Only the totally
burnt bricks have to be used. This is because the pieces
of normal bricks get reduced to mud after some years and
defy the very purpose of facilitating drainage.
sheets too can be used simultaneously to facilitate better
drainage. The corrugated sheets should be placed at 3' distance
and should be placed in such a way so as to lead the water
to the drainage holes.
5: Spread HDPE net
HDPE net( wire mesh) over the bricks. This will prevent
the garden earth and manure from getting into the gaps in
between the brick bats.
6 : Construct drainage chambers
the terrace is quite big (more than 500 sq. ft.) then construct
drainage chambers at various places on the terrace with
pipes leading to the main drainage holes. This is done to
prevent water from stagnating on the surface of the garden
in case of heavy rain. The drainage chambers should be constructed
in such a manner that when the final garden is done it will
get covered by the lawn and not be noticeable by everyone.
7: Spread the growing media and plant
a mixture of garden earth, manure and soil rite or peat
moss to the desired level. Carry out the planting as per
