Can Roundup be used at this time of the year and during the winter as an effective weed killer?

Answer 1

Only if your weeds are actively growing.

Answer 2

You can use it at any time of year. I have used it successfully in all seasons. The only thing that is necessary is that there is no rain (or snow?) for two to three hours afterwards and that the weeds have sufficient growth to absorb the weed-killer. If they are in a distressed state, either from cutting or perhaps frost - it won't work so well.

Answer 3

This time of year get a granule Pre-emergent and lay it down. First frost and freeze will get the ones there now and the pre-emergent will stop the seeds laid down now and that will genimate in the spring.

Roundup is an all plant killer used on growing plants....Bayer makes a good spray for broadleafs but y you do not need anything now.

Answer 4

Yes but in winter it takes longer for effects to show.
For a quick clean up try using a dessicant weed killer, I use Preegolone

Answer 5

roundup stops a plants ability to absorb water, annual weeds will be dying soon anyway, if not already. Perennial weeds take nutrients from foliage and store them in their roots for the next season, so now is a good time to really stick it to the perennial weeds as long as they are still active, not sure of your location

Answer 6

you will waste your 'stuff' you need temps over 70 and 24 hours of dry heat for the chem to work. Wait till spring and warm weather to see good results. Or a good clue is to read the bottle the Roundup is in.

Answer 7

Weeds do not grow in winter, use a weedkiller when weed are active Spring, Summer & Autumn

Answer 8

50oF is pretty much minimum temperature for glyphosate to work, as it needs an actively metabolizing plant, and plants don't do much during cool weather.

Remember that if you're near water, you need to use Rodeo or other glyphosate formulation certified for use near water because the surfactant used in Roundup is pretty toxic to aquatic life.

Answer 9

You can use it but a bit of a waste as the growing period of most plants is slowing down
Better to wait when it all starts up again in the beginning of spring

Answer 10

Of course you cant drink it. You should wear a face mask when using it and make sure not to leave any exposed skin when using it in case it drifts onto skin. It may smell like dishwashing detergant, but that doesn't make it safe.
