Hi all,

I have a client with a large area covered in weeds. He wants love grass to cover the area. I sprayed round-up last week. A LA told me I should wait a month before seeding the grass, but it seems to me that gives the weeds a chance to re-establish.
Is he right? Or does anyone know better?

Thanks,
Smitty

I've never had trouble planting within 24 hours after spraying round up. It's a systemic, to my understanding, which only works on the plant, directly through to the roots and not in the soil.

Never tried seeding though.

From my experiences, Terre is right. Ive planted bare root trees less than an hour after we sprayed "tree rings" with round up and didnt have a problem - just dont get any on your shoes or it will track.

There is no easy answer. What does the label say? They are the directions to follow. I have planted as early as the day after spraying with no problem but I would wait 2 weeks if I am seeding, although I would bet that you could do it sooner. (new weeds start germinating within days)

2 days at most. rd-up is a systemic meaning it requires contact with plant tissues. it will have a soil life (the residue) but not one that will actively harm plant tissue after 24 hours. the residue's soil life is only detrimental to the organisms in the soil.

the dead weeds will create a husk that will take up space. these husks look unnattractive and can be tilled away making it look nicer and improving the soil.

tilling is really important. roots grow in the air spaces in the soil. the more you open the soil the better your plant will grow.

We've never had any issues with planting after using glyphosate. I wouldn't hesitate to seed an area that was sprayed last week.

Thanks folks!
