I installed a retaining wall island in my front yard and around teh front perimiter of my house and bought what I was told was "clean" fill to back fill both areas. Now they are both full of weeds and I'm tired of using roundup only to have the shit come back 2 weeks later. I want to kill this stuf but not leave the soil toxic as I want to plant / finish landscaping shortly after. What can I do?

 

You do know that there is an entire forum devoted to Home & Garden issues here on S2KI, don't you?

Damn I have never seen that forum dave.

 

I can't even believe that. I guess if they have an RC forum then...

newbs.

 

Best bet is to pick the weeds and be sure to pull the whole weed out, including the roots. Leave any roots behind and they just come back. Once you pull them out, spray the Round Up as a preventative measure.

I did lots of weed pulling growing up as a kid.

 

I used weed mat and covered that mat with rocks. Works sorta, but i haveta spray weed killer every now an then.

 

Put clear plastic over it and weigh it down with stones or bricks. Do it for about a month. The heat will kill all weeds and sterilize the soil. Happy gardening.

 

The mat suggestion is a great idea but it can also back fire so be sure to clear out all weeds first hand before putting it down. My parents did it and the weeds just ending up growing beneath it and then grew to poke through. Made my job even harder.

Haven't tried the clear plastic idea but is worth a shot.
