|
Hi, we have a medium sized area of grass but we want to kill it off and put in some raised planter beds for next years vegetables.
What would be some options for killing the grass off?
Should we just stop watering it? But then, when it rains, won't it start growing again?

My standard answer is to cover it up and leave it to roast. We use black plastic or a big tarpaulin. I guess that won't take long where you are.

You can build your raised bed now put a thick later of newspaper or cardboard on the bottom, right on top of the grass. Fill the bed with soil. And plant right now.

I agree with Wrennie, but you don't need to put a layer of anything down. If the dirt is deep enough, it will kill off grass. I've done this with birms and raised beds.
It saves on digging and no chemicals.

Agree with others -- just don't use chemicals. There are easier and less toxic ways to do it.

Thanks everyone for you replies and advice. I'm sorry for my late response. I didn't know the dirt would kill the grass. hmm...I would like to build the beds now and fill them up and plant some things in them, but, we're taking an extended vacation to Turkey for the summer, and so I will leave it for when we get back.
About how deep does the dirt need to be so the grass doesn't grow up through it?

Hiyah Melissa,
There are machines that you could rent to de-turf your lawn--cutting it under it's roots and letting you roll-up strips of it, which you could dispose of later (like onto your compost pile or to let a friend use the strips for their lawn.
Anyway. If you are planning on making raised beds where the lawn is I would suggest that it is best to first double dig the lawn before dumping the new dirt/compost mixture for your new beds. Do not rake the double dug ground after turning it, the uneveness will be filled in by the finer dirt that you will be dumping on top--a sort of meshing of the two, you see what I mean?
The reasons for this are that there will then be a more "natural" binding between the present lawn and your newly dumped soil layer...secondly, and perhaps more importantly--you can avoid having what would effectly be a 'pan' under the new earth.
Why is this important? Well because if there is what is known as a "pan" under the new soil it can be so closed and hard that water going onto the beds from a garden hose or from the sky might not drain away properly and remain sitting there like a sort of pool, resulting in water-logging and this would not be good for your flowers or crops. It wouldn't be the first time this has happened.
I know that it is extra work, but I honestly believe that it is best. I would do it this way if I were in your circumstances...without doubt.
Double digging is something that I believe you should do whether you kill or remove the grass or not. It's removal is not the essential thing here.
I am a very strong believer in the proper care and treatment of soil because in my view, soil is the very essential basis for gardening in a convential way and thus proper handling of it and treatment of it is the single most important aspect of successful gardening.
