To add my own 2 cents, I used ROUNDUP on my raised garden bed I made. I was advised that if I just dumped the dirt on the sod, it would grow right up through the dirt. I used roundup, and the label said to wait 3 or more days for tomatoes, I think. I gave two applications over a week, and then planted a week later. I have tomatoes and vegetables growing like a jungle. The actual info is on ROUNDUP's label for each type of plant or vegetable....check it out.

Hi all, A nice friend of mine has decided to let a poor soul like me use part of his backyard for growing some tomatoes!! However, he sprayed a weed killer called "Round up" over the area a few months back to kill off some tall weeds (he was planning to cement the area but ran out of money) Is anyone familiar with Round-up and it's effect on gardening? I've been told it is a 'systemic' weed killer, although I'm not quite sure what that means exactly...Should I till the soil or will that put the poison in the soil deeper and be a long term detriment to my tomatoes? Is there anything I can add to the soil to counter act any lingering effects? Trying to avoid a disaster... Greg Park zone 10 CEO-in-Training Park Steel Company, Inc. Park.Steel@worldnet.att.net
