Weed Killer

Proud owner of a section of allotment (yaaaay!) It has been dug over this summer but has a lot of weeds - digging most out but probably 20 to 25 dandelions - as we know, they are b*ggers to get out - I dug down 2 feet for a big one and still snapped off the bottom part of its root

I am thinking of using a handheld Roundup spray (or something similar) just for the dandelions, on the leaves - is this okay do we know? I won't be planting until April / May

    Congrats on your new acquisition!

    That's what I use on dendelions and the like. Sometimes needs a couple of applications but does work.

    I think the only problem you have is the time of year now. Plants are shutting down now for winter and Roundup needs to get into the plant to work, so it depends on the weather - but worth a try now, if they come back in the spring, give them another blast then.

  • Fair enough but I wanted to know, is this the sort of thing I could use on soil I wanted to grow in, next year? Or would it have a detrimental affect on anything I planted - I was thinking that it would only kill the dandelion 


    Why too late Verdun? Should it have gone on in the summer?

    Plants have to be vigorously growing and have a good amount of leaves for Roundup to work well. At this time of year they just don't.

    Roundup is inert if it hits the soil, it only affects foliage. It will kill every kind of plant though. So if you get a splash on anything else, it will die.

    Winter is a good time for forking out the perennial weed roots. Treat any regrowth in Spring  with weedkiller when it starts to grow again.

    That's what I'd do Fidget - I'd dig over the allotment again, getting out what weed roots etc that I can.  Then in the spring I'd treat any re-growth with Roundup.

    Remember to leave the weeds long enough for the Roundup to take effect.  They need to be brown and dead before you pull them up otherwise the glyphosate won't have got into the roots and any little bit left behind will regrow.

    Rosate 36. Amazon. A tad of an outlay up front at about 38 quid for 5 ltr but you dilute it and it goes a very very long way, becoming economical in the long run. Works for me 100%. Just follow the instructions. Works on just about everything and is animal friendly. Just, as with most products of this type, keep it away from water.

    And remember, if diluting chemicals into other containers - label them clearly!!!

  • I agree with Simon69.  Roseate 36 is good stuff. 

  • Hmmm thanks to all for your contributions - I should make it clear that I am digging everything out other then big dandelions - they still have a good amount of green leaves above ground so I thought I would 'zap' 'em.

    As I said above, it is very difficult to completely dig up the darned things, especially the big, well set ones - the roots go down 18" to at least 2 feet and as we know are great survivors i.e. snap off leaving a qtr inch to grow again.
