Hi
I want to dig up some more of my couch lawn to extend a garden bed.
Previously I have been digging it out and trying to save as much of the
top
soil as possible. I should add the lawn is only four months old, grown
from
seed and the roots don't go down for miles, YET!! :-)
I guess I am starting to get lazy but was thinking that maybe I could
spray
the area with Zero or similar. Will I be doing the wrong thing in trying
to avoid digging. I would like to be able to replant the area within a
month.
Thanks, Sue Karratha.



Unfortunately no matter how hard you try it's nearly impossible to dig couch
out, especially if you are trying to keep the soil too.
The best thing to do would be buy Glyphosate (aka Roundup but the name
Glyphosate is cheaper and exactly the same stuff, think Kmart has it), in a
concentrated form.
Mix it to the rate of 150ml per 10litre (so 15ml per litre), and spray the
whole area you wish to kill.
If the grass is quite long give it a mow first. Dont spray immediately after
mowing, wait a few days at least, a week is good. If the grass is average
length just spray it, don't bother mowing.
Then a few days after spraying treat that sprayed area as if you wanted it
to grow good. Don't let it dry out, keep it watered as if you would want it
to grow good. This will give the best kill. You can plant it in 4 weeks
then. Leave the couch there, or dig it over. Don't bother removing it. You
can even mulch over it in about 6weeks.
The only problem you may have is the lawn was raised from seed. So any
digging/planting could stir up non germinated seeds. Just keep an eye on oit
and dig out or spray any new couch you see.

Good luck
N.B. The above rates are for mixing concentrated form glyphosate/roundup.
