Prepping for turf - bindweed

Hello allCurrently quoting to turf some overgrown areas of garden which have a heavy infestation of stingers and bindweed and just want some advice on preparation.I'm thinking a strong spray with glysophate (or clinic ace which Is what I use) now, but I am concerned that bindweed will merely laugh at it and still be around next spring.So how would you prep an area that is full of bindweed in readiness to lay as a new lawn?Cheers

  • bind weed is easy to kill wiht Glyphosate.

    You have one problem - Its too too late in the year for Glyphosate to reliably work, infact if it stats as cool and wet as it is for another week, then thats it, no chance at all of anything but a synthetic Auxin type herbicde working.

    I would spray Depitox (2.4D) Today on those weeds, 90% kill if applied knapsack and mixed at 40ml per l - but again, It may be too late in the year, with the plants going dormant for winter, I doubt you will be able to kill off now.

    Could you not follow up treat any growth in spring?

  • By the time you've sprayed, and the roots are dead, it'll be spring!

    If you rotivate the ground without being sure the roots are all dead you'll be creating millions of cuttings.

    Ideally, I'd say put it off to next year and do it right. Nettles and bindweed aren't a huge issue in lawns as they are killed off by mowing, or treating them, but it won't look good if the new lawn is infested with them as soon as things warm up a bit.

    If it has to be done now, I'd be careful to explain to the client that it's really too late in the year to kill the weeds with any success, and put in writing a programme to deal with weed growth next year?

  • I agree with the previous two comments but would add where is the bindweed coming from? It is very invasive so make sure it doesn't keep on invading regardless of what you do with what is there already. Keep the borders clear and go beyond the given boundaries if you can.

    David - I have found that bindweed is anything but easy to kill of with glysophate, particularly with a heavy infestation of it, which is my main concern.

    Yes ideally a spray now (though agree it is a bit late), followed by treatment in the spring would be the way to go, but in my ideas still doesn't guarantee it's iradication
  • Hi Simon,

    I've had a lot of success with treating it. But, that's always been with careful hand-treatment of small amounts, or spraying at better times of the year for heavy infestations.

    I used to try to avoid turfing jobs in the winter, but I was working on areas of heavy clay so it wasn't really an option. What preparation is needed? If it's got to be rotivated then you're causing more trouble than it's worth. How long could a spray be left to work? At this time of year it would need weeks, at least, to be absorbed in to the root system and have any effect.

    I guess you are saying you're 100% sure that it'll be back with a vengance next spring, all over the new grass. As I say, it's going to be kept in check with regular mowing and selective treatments, but the client needs to know this (in writing) in advance. My worry would not be dealing with the weeds, but the client blaming you for them coming back.

    Who's going to be responsible for the on-going maintenance? I often agree on-going work between me, as the regular gardener, the client, and someone doing the landscaping. That way all three of us know what to expect. If it's the client mowing their own new lawn, I'd be concerned they won't have the knowledge and patience to deal with it.

  • Hi Simon,

    If you spray with Roundup Probiactive 450, you will get a pretty good kill, even at this time of the year. This is obviously glyphosate based, but it is stronger than Clinic Ace and also has a lot of additional oils in it to help it work more efficiently and also faster. A treatment now with a follow up in the spring should see it gone.

    If you need anything else, please don't not hesitate to get in touch.

    Cheers Ollie

  • I've found similar too - hence the very high tank concentration used to kill it - anything less and it will seem to shrug the hit off.

  • Belt and braces - spray now and again on any new growth in the spring, prep soil, leave a month, spray again if required, lightly prep again and lay turf.

    If the client wants the job done sharpish, then spray now, prep and lay turf, but warn client(in writing) that this is not ideal and weed will probably appear in the spring, but regular mowing and selective weedkiller applications will see it off.

  • Just to clarify Ollie's comments:

    I'm sure he means re-treat in the spring but NOT if you've turfed it! :-)

    Not trying to be patronising, just covering the obvious in case someone inexperienced reads this. I can see the new post next year: "I followed the advice and the grass has gone yellow".....

  • This is true Paul, guessing I forgot that it is not just professionals that might read that post!
