Hi there, we had some industrial weed control fabric layed down on a large area at the bottom of our garden.

We then had 2 ton of gravel placed on top if this at around 5cm depth.

We then have a trampoline placed on the gravel. The problem is it has only been a few weeks and the weed that has grown through is quite shocking. I thought by doing what we had that this would stop the weed. But its there and getting worse.

Please does anyone have any advice on what we should do? 

Thank you in advance.

Barry - these are more likely to be weeds seeding in from the top rather than ones growing up through the fabric so they should pull out easily. Determined little b*****s aren't they!

Get the kids onto pulling them out before they get on the trampoline! 


Are you sure you've been sold industrial weed membrane ? where'd you buy it from and is it about 5mm thick.

Pull some of the gravel back and check to see if they have actually grown through.


You did destroy all the weeds before you laid it, didn't you?  If not the weeds will grow through.


We are complete garden novices. The weeds were removed before we layed the fabric down. It was quite thick and in one huge sheet. Not sure of the thickness. They do pull out easily, but there is quite a lot of them that have grown through.

Please see the picture of the type of weed growing through.

Would we have to take all the gravel off and start again?

 Thanks for the replies.

Horsetail, one of the toughest weeds on the planet. Has been around since before the dinosaurs. You could trample on it to bruise it and then spray with Glysophate based weedkiller. Or you could pull it regularly to weaken it and perhaps eradicate it. But could be a long term job. Sorry... and good luck.


10 yrs I've been battling with this weed and I can see another 10. Absolute nightmare !! 


My mums been battling mares tails for 50 years. My dad tarmacced over the front lawn, but they just push through it.


I do sympathise- with you as well marshmello. It can be hellish to get rid of. We had them growing into our pond at last house so couldn't do much about that- had to just keep yanking out all the ones surrounding it. Usually when you have membrane down, they grow underground and pop up at the sides of the fabric but it just depends how heavy the covering is. I've used Resolva on them (which does work) but as Woody says - pulling them also helps to weaken them if you don't want to use chemicals.

Look on it as a free workout zimmo!

Touch wood, domt have this weed but a super strength b & q for example......should do,the trick. I agree with woody, some bruising of the weed either by scratching or by trampling....not too hard...before spraying does ma,e a big difference.  

Incidentally, on an earlier thread about glyphosate and jap anemones I have successfully eradicated mine by spraying.  I used Resolva, 2 sprays, few weeks back and the suckers have all disappeared.  


Encouraged by your post on Japenese anemonesVerdun ,have been unsucessfully trying to get rid of these from the path for ages,will give Resolva a try.

Hiya Gilly

Just make sure it's a dry day and I think glyphosate works best on cloudy days. 






Well already i have learnt so much. Thanks for the kind replies, at least we know what we are dealing with now. We shall set about doing the things you have told us on here and at least keep on top of the problem. It seems that we are not alone. Great forum to be on and will be using it for further advice etc.. Thanks all so kindly.

One last thing from me....glysophate kills everything so take care not to spray your favourite plant your Granny gave you! 


I have tried weed killers also boiling water with salt ,still they come through x
