Brambles and Grass weedkiller

Postby Julesuk » Wed Dec 09, 2020 7:24 pm

Can you kill grass in late autumn / Winter with a glyphosphate weedkiller ?
I only ask as I wouldnt normally weedkill this late but grass grows above 5deg C so it would work would it not ?

I know it will work in the spring onwards but madly after a whole season of trying
Vinegar, Salt and whatever I now need to rid a large patio area of grass and weeds.

whats think ?

If you can get a long enough dry spell it could work but they say no rain for so many hours on the instructions & I think fog, mist & frost could fall into that & make it ineffective. If you're a non-smoker & like car fumes the guy over the road keeps his brick drive clear of weeds with petrol & swears by it & if the proof is in the pudding his brickwork remains weed free all year. I've never seen it recommended anywhere & I have never smelt it & walk past almost daily. He just uses one of those pump sprayers.

I've no idea of it's credentials on the soil so you would check that, but if a patio & not a growing space & no run off into a waterway might be no worse than weedkiller???

1l of glyphospahte bought.
Obviously from.march to september best times but for grass as it grows above 5deg C I might try one application of it is to be dry for say 3-4 days.

I read somewhere that it might take 5-6 weeks in winter but it will be gone by spring.

will inform

When applied in summer at least, you only need a couple of hours without rain for it to be effective. You of course want proper glyphpsate, eg Roundup 360, rather than the common or garden centre homeopathic dilutions. It works best in late summer or early autumn for perennial stuff, when it gets taken back down to the roots, but I guess you know that.

I have been using sbk for years
and it works fine on weeds but of course I
have realised late this year it is no good
on grass , indeed doesnt kill grass.

i thus have to suffer a winter garden not in
perfect condition .......
I am.armed and ready now at least. got mine off ebay.

thanks for info

You are probably right to wait, I've finally remembered to check some dandelions I sprayed about three weeks ago and they are still green and healthy looking.

I did read somewhere on the net .... a chap with a big garden who sprayed in winter.
I think he said it takes longer 6-7 weeks but the weeds (and grass) wont be there in the spring . Said something ab8ut it being better as weeds not seeding.

if I see 4 dry days and its warmish in front of me I'm gonna do a test.
