"weed" is a very generic term.

A few weeks ago a hired landscaper for a local dollar type store sprayed
roundup on the general grounds and parking lot perimeter. It has/had all
kinds of "weeds". It killed the Johnson grass commonly called a "weed", but
none of the other "weeds".


I agree with Steveo here. If a landscaper can only kill one type of
weed in a parking lot with an application of weed killer, I'd find a
new landscaper. Herbicides like Roundup kill a very broad range of
vegetation, are easy to use, and very effective.





You should not have to use a herbicide more than once. If it don't work the
first time, its not going to work.


A lot depends on the concentration of the herbicide. If you're
treating a large area, you typically use a mix strong enough to kill
just about anything that is there. However, it's not unusual to find
some weeds that are tougher to kill or areas where the spray was not
perfectly applied due to wind, etc. So, having to do a second pass 2
weeks later to get a few remaining weeds that have not been fully
killed is not unusual.




If the ground is reasonably not rocky but fertile, just rent a rototiller.
Till up the first 3" or 4" of ground and let the sun and air kill the
foliage. Then rake out the foliage with a bow rake.


Have you ever tried to rake after tilling two foot high weeds and
grass? Tilling it won't kill it all. You now have clumps of crap,
lots of weeds/grass still growing, and it's a real back braking mess.


Throw some sod on top
of the prepped soil. Keep it well watered every few days, not everyday,
don't drown it.

Hello

I have an area of garden that I wish to turf and would be grateful for
some help with how to prepare it.
The area is approx 30' x 30' and has lots of weeds.I keep digging them
up and have put weedkiller on them many times (with little effect),then
i dont get the time to complete the job and the weeds come back.

Can i dig out most of the weeds and turf straight over ? someone
suggested putting black polythene over,waiting for the weeds to die and
then turfing ?
Will the weeds grow thru the turf or will the turf prevent this
happening ?
Can i rotavate the blighters over ?

I really know nothing about gardening (see my username for my
speciality) and my back wont stand much more weeding.The end result
just needs to be grass not an immaculate 'lawn'.

Here is a picture link to give you an idea.

Any help would be greatly appreciated.Regards
