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
