I introduced this because it’s the better way to kill weeds. Remarkably, it’s based on a naturally occurring ingredient in geranium leaves and it works very fast.

  • 100% glyphosate free and totally bio-degradable.
  • Extra fast acting, you can see the results within 24 hours.
  • Double action, unlike some weedkillers, mine works on the leaves and the roots, so it’s a better way to control a wider range of weeds.
  • Treats up to 60sq metres of weeds.

If you look at the weedkiller section in a Garden Centre, you’ll be amazed by the range on offer. Some contain glyphosate (a controversial chemical banned by some retailers), others are only effective on the leaves but not the roots (so aren’t that effective on the tougher perennial weeds like ground elder) while some weedkillers can take weeks to work. This is different. It’s glyphosate free, works on annual and perennial weeds, and it works really fast. It’s the way forward in better weedkilling!   

  • Extra fast acting. Some weedkillers can take weeks to work. You can see this working in hours! On hot sunny days, results can be seen within 2 hours (see video clips below), on cooler, cloudier day, it still works within 24 hours.
  • 100% glyphosate free. Reassuringly, this is based on a naturally occurring ingredient found in geranium leaves and is totally bio-degradable.
  • Treats a wide range of weeds including ground elder, bindweed, dandelions, nettles and couch grass. It’s also very effective on moss, weeds and grass growing in paving. It’s not recommended for control of Ivy and Japanese Knot weed, or for treating weeds in lawns (use a lawn weedkiller like my Lawn Feed, Weed and Moss Killer for these).
  • Pets and kids, can re-enter the treated area once it has dried.
  • For best results: Spray on a dry day, on dry leaves, and don’t spray if it’s likely to rain within 4 hours otherwise the weedkiller won’t be fully absorbed. And try to spray all of the leaves to make sure as much weedkiller as possible is absorbed.
  • Treats up to 60sq metres of weeds.

FAQs

What weeds does it work on?

It works on most weeds including ground elder, bindweed, stinging nettles, chickweed, couch grass as well as moss and algae.

Are there any weeds it doesn’t kill?

Yes, Japanese Knotweed, ivy and horsetail.

Can I use it on lawn weeds?

No, it will kill the grass as well as the weeds! For safe control of lawn weeds, use a specific lawn weedkiller, such as Vitax Lawn Clear 2.

How quickly does it work?

You can see results fast, within 24 hours. In warm sunny weather, results can usually be seen even faster.

What’s the dilution rate of the concentrate?

Add 85ml of concentrate per 500ml of water.

How long can I use the diluted concentrate solution?

It’s at its most effective for 24 hours after diluting.

How do I get the best results?

The weeds must be dry before application and don’t spray if it’s likely to rain within 4 hours after application. Spray all of the green parts of the plant. Drench the weeds thoroughly to ensure the best possible absorption of the active ingredients.

When using in summer or on very warm days, spray in the cool of the evening. If you spray when it’s warmer, much of the chemical will evaporate before the plants have had chance to absorb it.

Does the size of the weeds matter?

Double Action Weedkiller can be used on all sizes of weed. But the effect is better when the green surface area of the weed is as large as possible so that the maximum amount of active ingredient can penetrate the leaves and reach the roots. Best effects, and minimum use of the weedkiller, is with weeds 5-10cm (2-4in) high.

Will any weeds grow back?

Most weeds will be killed outright, but some well-established perennial weeds may produce some re-growth a few weeks after spraying and this will need another application of weedkiller. Further applications may be needed, depending on the severity of the infestation

Can I use it in cooler months?

Unlike many weedkillers, which only work in warm weather, mine works in cool weather too, but only if the temperature is above 7C. Weeds will die back more slowly in cooler weather. Once the temperature is above 10C, it works faster.

How soon can I sow or plant after using your weedkiller?

The weedkiller biodegrades in contact with the soil, so you can sow or plant 24 hours after spraying.

Can I apply it in a watering can?

We don’t recommend applying Double Action Weedkiller in a watering can. This is because it is more accurate/precise in a sprayer, and the water droplet size when applied by watering can is much larger, so the weedkiller doesn’t work as effectively.

Is it safe to use around children and pets?

The active ingredients in Richard’s Double Action Weedkiller are Maleic Hydrazide and Pelargonic Acid (taken from pelargonium plants). Both are regarded as being safe to human and animal health (maleic hydrazide is sprayed on potatoes and onions and other root crops to stop them sprouting in storage!). Keep them out of the area when spraying and while it is drying. Pets and children  can re-enter the treated area once the product has dried.

Always follow the instructions on the container and store it securely in a safe place.

9 reviews for Double Action Weedkiller Concentrate 1020ml

  1. Jane Usher (verified owner) –

    As usual an EXCELLENT product, works on all the weeds that appear in garden, even have had sucess with horsetail.
    The only problem is the bottle, lid and dosing system, not easy or sucessful at measuring corectt amount, which is probably why some reviewers have not had good results. I have had to resort to, firstly struggling to open the lid, extremely difficult, then realising have to leave lid on, then tip bottle upside down to measure 85ml dose, this done, turn the bottle upright again, then while struggling to get the childproof lid off losing a percentage of 85ml, eventually I tip out whatever is in the measuring chamber into a measuring cup to ensure I mix the to the correct strength with water.
    PLEASE redesign the bottle, it is such a good product that really works, and not harmful to the wildlife and enviroment. I am sure just a child proof lid and provision of a measuring cup would be far better, and I would feel I was getting the mix correct every time for sucess.

  2. Philip Brown –

    Excellent product but the dosing system needs a rethink

  3. Viv Rosser –

    A big fan of your weedkiller but hate the 85ml dosing system which doesn’t work!

  4. Janice Cotton –

    Fabulous product…..used it years ago, then decided to buy the popular ones with disappointing results…needless to say am back with this one and have even recommended to my Gardner as he could not believe how quickly it works……highly recommend

  5. Nicky Titchener –

    This must be the best weed killer ever made! It works like a dream, destroying everything it comes into, so be careful if you are using it near your plants. If you’re applying it on a sunny day, the weeds, like dandelion, curl up and die within hours! I wouldn’t dream of paying £25 for weed killer normally, but this is the king of weed killer, with the added benefit of being produced from natural sources.

  6. Mavis Yates –

    I bought this from QVC over 12 months since and it never lets me down. My husband can’t believe how quickly it works. . It is an exceptional product as are all your products.

  7. Brian Martin –

    This is without ant doubt the best weedkiller on the market. As long as you follow the instructions and only spray the leaves of what you want to kill, you don’t even have to worry about plants nearby being killed.
    It is the only thing that kills my problem of bindweed from a neighbouring garden. Brilliant on Doc leaves also.
    Finally, for controlling and killing weeds in paving, blocks and resin based there is nothing better.

    Guess you could say I recommend this to product to all.

  8. Tony –

    I bought the weedkiller and spray applicator from QVC. I find that the weedkiller is the fastest acting I’ve used since paraquat was banned. It really does work.

    The spray applicator is also very convenient compared to getting the pump up spray out. One thing that I will say is it could do with a 2ft, or so lance as when using it at arms length you can breath in some atomized weedkiller. I now use a mask for safety.

    All in all an excellent product.

  9. Marie Coote –

    I bought this when it was the TSV on QVC with auto delivery. I’m so glad I did. I cannot believe how quickly it acts. My problem is bindweed in the borders. On a sunny day I sprayed the weeds and within 2 hours they were shrivelled up and brown. This is a miracle product that works. Buy it and you won’t be disappointed.
