As the drought continues and people become more
water-wise, Harvest is frequently asked about Native
grasses as lawn substitutes.
More Australians recognise the natural subtle beauty
of our native plants and are comfortable moving away
from our European heritage and embracing native plants
for their lawns etc., of which there are many native
solutions for.
There is no native grass being cultivated for sale
that will tolerate heavy usage, so if your plan was to
use it for playing soccer on every weekend, or if you
need to walk in the same place daily (and cannot put in
a path), then this is not for you. However, most people
don’t use their lawns like this and are just looking for
a patch of green for the kids to play on or even just to
look at or sit on sometimes; if this is you, then the
grasses below are ideal.
Getting
Started
Questions to ask yourself
before choosing a grass, or to discuss with our staff.
Preparation is the difference between a great lawn and
an average one.
- Is it a sunny
site?
- What type of soil do I
have?
- Does it get watered?
What do I need to use the
grass for?
- Will children or pets use
the lawn?
- Are there any drainage
issues?
- If heavy foot traffic is
expected, can I put a path in?
Steps to Creating a Native
Lawn
- Spray the existing lawn
area with herbicide (at least twice in most cases to
ensure all the old turf has died)
- Leave the area for a few
weeks to be sure the herbicide has worked.
- Level the area and if
necessary use a native garden mix to fill any holes or
topdress.
- If soil is compacted, use
a pitchfork to aerate the soil.
Using seed - Plan for
spring planting.
- Spread the seed evenly
over the soil. This can be done by mixing dry soil or
sand with the seed to help disperse the seed
evenly.
- Water well and water
gently to avoid dislodging seed, and continue to keep
the ground moist until germination, and slowly harden
off by watering less until established.
- Do not mulch or cover the
seed except with a very light layer of sand or native
garden mix if the seed really needs
holding down (do not plant any deeper than the
thickness of the seed itself). In most cases the
watering will keep the seed in place and will tamp it
into place. (Remember, fairly gentle watering is
needed.)
- Check for weeds as they
will germinate quickly and overtake your grass
seedlings, stealing nutrients and water. So, please be
reminded to have your area weed free before sowing
native grass seed.
Using tubes or
Grow-cells
Ideally, plan to start in
autumn or spring to give your new lawn the best run-up
for the heat of summer. (Some grasses prefer a cooler
growing situation, others a warm one).
- Mulch to improve the soil
and keep down weeds with fine compost based mulch
suitable for native plants.
- Plant your tubes at the
rate of 10-15 plants per square metre.
- Water well for the next 2
weeks or so, depending on if you use grow-cells or
tubes and the amount of rain over the establishment
time), and continue watering weekly until established.
This will take about a month.
- Water occasionally during
the heat of summer.
- Watch for weeds.
- Remember that a log or
rock is a great place for moisture retention so place
those moisture seeking species at the base.
Seed versus
Plants
Many people have difficulty
deciding which method to start their lawn with. Both
methods have their advantages.
Seed.
- Seed is cheaper and is
easy to sow.
- Seed takes longer to
establish (about 8 weeks in summer and 12 weeks in
winter)
- Less water is needed to
establish the lawn over all.
- Weed control will be
necessary.
Grow-cells
- Planting grow-cells takes
longer and are more expensive to buy than seed.
- The plants will be
established faster than seed.
- Plants are likely to be of
local provenance and therefore adapted to the local
environmental conditions and won’t pollute the genetic
integrity of the local plants in your area.
- Follow up maintenance will
be required until established such as watering, but
once established will require very little.
So you can see that the
person choosing the seed will have spent less money, but
more time on their lawn than their neighbour who bought
their grass in tubes for more money but is out on the
banana lounge enjoying it sooner.
Tubestock versus
Grow-cells
- Grow-cells are cheaper
and easier to plant.
- Your selected grass may
not be available in grow-cells. Place your order in
advance to be sure you get the plants in the size
needed.
Maintenance
- Mow your lawn depending
on the species chosen and the effect desired. Use the
highest setting on your mower and occasionally leave
the catcher off as this will help keep out weeds and
if there is any seed at the time of mowing, some of
these will germinate, keeping your lawn fresh and
lush.
- Most native grasses grow
during summer and are dormant during winter. This
means you should only need to mow them in summer. All
the grasses recommended below will keep their green
colour over winter, and none need over-sowing.
- Fertilizing will only be
necessary in extreme cases.
Grass types
- Mostly, native grasses do
not have “runners”. This is not a bad thing at all.
Have you ever had to pull all the Kikuyu out of your
vege-patch or garden? Well, you know what I
mean.
- Most native grasses grow
in clumps, and are spread by seed. It’s a good idea to
let the plant set seed at least once a year to keep
the lawn fresh, will greatly reduce spacing between
the ‘clumps or tussocks’ and provide a wonderful
‘springiness’ to your lawn.
Microlaena
stipoides “Weeping
Meadow Grass” or “Rice Grass”
- This grass is highly
recommended for most sites. It will grow well in sun
or shade, some forms retaining its lush light green
colour even during drought. It will also tolerate and
look good in most soil types including waterlogged
clay, but does its best in moist well-drained soils in
full sun and shady sites. (Shady sites tolerate more
dryness).
- Weeping Meadow Grass mows
very well and tolerates light traffic. (It will stand
kids and pets playing on it).
- This grass contains
higher nutrients than the exotic grasses being used as
feed in paddocks all over Australia for horses and
cattle etc.
- The only small problem
with this grass is that the seeds can irritate the
skin of long or thick haired dogs. This can very
easily be avoided by mowing the grass before the seed
matures.
- Available in seed,
grow-cells and tubestock.
Chloris truncata
“Windmill
Grass”
- Windmill Grass is a
lovely tussock grass with highly attractive flowers
and light green foliage.
- It is recommended for dry
sunny sites but will also tolerate moist soils and
some shade.
- It mows very well, but
keeps a dense habit even when not mowed. Great for
rocky sites or steep hills.
- We recommend letting
Windmill Grass flower in summer at least every second
year as the plants can be short-lived and the
resulting seed will keep your lawn healthy.
- Usually available in
seed, grow-cells and tubes.
Bothriochloa
macra “Red Leg
Grass”
- Red Leg Grass is a very
hardy, deep green, fine leaved grass that turns a
pretty red colour in winter.
- It is recommended for dry
sunny sites, much like the Windmill Grass, but will
also grow happily in moist soils.
- It mows very well, but
keeps a dense habit even when not mowed. It should
only need mowing after seeding in spring to summer.
Great for rocky sites or steep hills.
- Usually available in
seed, grow-cells and tubes.
Themeda
australis “Kangaroo
Grass”
- Kangaroo Grass is a very
popular ornamental grass, as well as being suitable
for native lawns.
- It is recommended for
dry, rocky or sandy soils in full sun to shade.
- Kangaroo Grass has
adapted differently to the various places it is found
throughout Australia; from forest sites it grows
taller, from coastal sites it grows shorter. For a
lawn, the coastal form is more suitable, not needing
as much mowing, although the forest form is perfectly
fine provided it is mowed.
- Kangaroo Grass can have
an attractive red tinge to the winter foliage, which
contrasts nicely to its normal light grey-green
colour.
- Available in seed,
grow-cells and tubes.
Austrodanthonia
spp. “Wallaby
Grass”
- Many forms of Wallaby
Grass have a fine textured leaf and small growing
habit that makes them suitable for lawns. Ask about
the forms local to your area.
- It is recommended for
most soils, in full or part sun. Although it will
tolerate the drought and thrive, it may lose its
lovely mid-green colour as it dies back a little.
- Wallaby Grass has very
attractive white flowers if left unmowed over
summer.
- Available in seed,
grow-cells and tubes.
