hi guys Joe here from Lawn solutions
Australia. Drought conditions are impacting a lot of areas at the moment
and being environmentally responsible with your water use is more important
than ever fortunately it is only in the most
severe circumstances over a considerable period of time where a lawn would
completely die off due to a lack of water. warm season turf grass species
commonly used in Australia need very little water to survive and are very hardy
in summer. when temperatures are really high grasses will enter a state of
dormancy where they shut down tissue growth to prevent moisture loss. they
will lose colour, become brown and dry with little to no leaf growth but they
will generally sit dormant until the next rain or irrigation event. you can
usually tell the difference between a dormant and a dead lawn by looking at
the crown at the base of the leaves, if the crown is white to off-white, chances
are the plant is still alive. a dead lawn will be dry brown and brittle right
across the plant from the crown to the roots to the leaves. remove thatch,
removing dead material from the lawn profile during spring will help the
living plant to absorb all the available moisture during the warmer months.
aeration improving the ability for water to penetrate to the roots will be
important to take best advantage of water when it is available but also to
improve moisture in the soil where it is needed during the next dry spell. stay
off the lawn, your grass is already having a hard time and the drier it is
the more likely it is to be damaged and unable to recover from foot traffic or
additional wear. water effectively, when you can water do so for longer and less
frequently this will encourage deeper roots which can delve deeper into the
soil to find moisture, by doing this it will allow your lawn to stay hydrated
for longer even through extended periods without rain. apply a wetting agent,
hydrophobic soil is caused by the decomposition of organic matter which
leaves a wax-like substance forming a coating on soil particles. after long
periods of dry weather soils can become dehydrated and this is when the
hydrophobic surface is exposed which stops water from penetrating. a wetting
agent like Wettasoil will help break down the surface and help water to soak in. the key to mowing your lawn during summer is to do
so during the cooler times of the day and to mow regularly. you want to keep on top of
leaf growth so you’re not removing too much at any time. by removing one third
of the leaf or more during any one mow will cause unnecessary stress to the
grass roots. as you can see here if the roots cannot maintain this level of
moisture to the leaf the leaf will close their stomata and lose colour.
stomata are cells that form the pores of the leaf surface, when the stomata are
closed there will be limited growth due to its inability to take in carbon
dioxide. When to irrigate? the simple answer is when your lawn needs it. when you do water make
sure you always comply with the rules and regulations set out by your local
Water Authority. if your lawn has lost some colour and vigor from the heat a
good option is Colorguard Plus, it’s a natural pigment with an added fertiliser
to help keep your lawn green and save on water during the drought conditions
