Good product for murdering grass/weeds?

[roo_ster]

With or without a match?

No match.  You want it to stick & do its work on the whole plant.

Some plant have an oily coating on their leaves that the surfactant helps cut through.

Astroturf.

(But then again, I'm the kind of guy who spray-painted a dead bush green once 'cause some people were coming over.)

And Kudzu is edible.  Seriously.

The leaves and stems can be eaten like an other greens, and the roots can be dried, ground, and added to soups or stews as a thickening agent.

What about covering the area with black plastic or the muslin (sp?) stuff? You do want other stuff to grow afterwards, no?

This.  Round-up is good for walkways, driveways, pavement, etc. where Nothing Must Grow There Ever Again.  That's why I suggested the garden hoe. and detcord.

Still a broadleaf.

Honey Locust is a legume also.

You can spray Roundup and 2 weeks later till or plow everything under and plant veggies. Different length of time for each type of Roundup formula. Decades ago I used to spray it and 2 weeks later till the area and plant either grass or landscape plantings.

Ground clear, etc., last longer and the ground is unusable longer.

I will never plant anything there.  When we sell the house a few years from now, the next resident may wish to plant something there.  How long does glyphosate/Round-up last?

Oh, thanks sanman.

The beauty of roundup is that it breaks down relatively quickly so there is no residual effects.

If you really don't want any weeds in there, cover with landscape cloth and cover that with mulch, rocks, etc after the herbicide application and plant mortality.

[RoadKingLarry]

With the Glyphosate you can replant some things as soon as three days after application. I will usually wait a week and I've had no problems.
Hot humid days are your best days to spray, the plant tends to "open up" and take in the moisture better making a little quicker kill.

[230RN]

Gee, I thought all the "cover with plastic" suggestions were covered by my astroturf suggestion.

Humph!  <exits with exaggerated Miss Piggy indignant flounce.>

High strength vinegar and sunlight works well, if you feel like going organic.

How much water can you boil and handle at once?  Vinegar can take a couple of days, but scalding them works in hours.

[RaspberrySurprise]

This ought to do it

I was just coming here to toss in the flame thrower idea. Can't believe it took us this long. We must be slipping.

Maybe we got tripped up by the det cord?

SWMBO recently did this to kill some grass coming up around the edges of our raised beds.  She added a little dish soap to aid adhesion to the grass.  It worked very well, killing all the treated grass in little more than a day.

Yea, I hate when that happens. 

[lupinus]

If you want to go natural and have a few weeks water the area well and then put some clear heavy duty plastic sheeting over the area and secure it with stakes or similar.

The plant and roots will cook under the plastic, especially with the summer season moving in.

Or if you don't wanna wait, Roundup.

[280plus]

Yup, I used aluminum gutter spikes and fender washers. I doubled the edges over before I spiked them down. Works like a charm. I also cut 3 sided holes for the plantings, folded the flap under and then spiked it down in there too. One spike per flap.
