SUMMER'S A BUMMER FOR NEW GARDENS
Sometimes there is no choice but to establish a new garden in summer even
though it is hard on the plants or turf and certainly not the most efficient
time of year to be planting.
e trouble is that sprinklers are only allowed to be used twice a week
when on scheme water, and three times when using a bore.
is may not be often enough in which case it will be necessary to apply
for an exemption.
From October 1 this year, new requirements for exemptions came into
force. Briefly they are as follows:
e soil must be improved over the whole new garden or lawn area.
An exemption will only be issued for lawn when it is for the whole of
the garden, ie. lawn laid as part of a new garden design for the whole of the
front (including or excluding verge) or back yard, or side on a corner block.
New garden design includes garden beds and lawn area.
Garden beds planted at the same time as laying the lawn are included
in the exemption.
An exemption will only be considered for a verge alone if the area
concerned is greater than 50sqm.
An exemption for garden beds will only be issued if they are part of a new
garden and not just a component of it. If you have existing lawn and only
install garden beds within it, an exemption will not be issued. Garden beds
must be mulched to a minimum depth of 50mm.
For irrigation, the requirement are:
If the system has been installed by a Waterwise Garden Irrigator Program
(WGIP) member, the conditions should have already been met, but the
householder must still call 13 10 39 and request the exemption be issued.
e householder needs to supply the installer's WGIP number when they call.
For all systems the irrigation controller must be able to be programmed to
accommodate the state-wide watering day roster applicable to the region and
must have an adequate battery back-up in case of interruption to the main
e system must include a rain sensor or soil moisture sensor, which must
be connected to the irrigation controller.
Lawns and gardens must be on separate irrigation stations with minimal
All emitters (sprinklers) on the same station must be the same type:
Garden beds must not be irrigated by micro sprays. Drip or sub-mulch
irrigation is recommended.
