How to stop weeds coming through your decking

Read our guide on how to stop weeds coming through your decking. A deck is a great place to relax with family and friends. But weeds coming through your decking will drive you nuts.

So, how can you avoid getting weeds under your deck and losing your cool in the summer? All you need to do is a bit of planning.

Get the weed control supplies you need to protect your decking now

5 tips on how to stop weeds rising through your decking

  1. Remove the grass. If your decking hasn’t been laid yet, remove or kill the grass in the area that it will go on. By doing so, weeds are less likely to become established and spread. Also, you’re less likely to have grass growing through your decking.
  1. Put down weed control fabric. Once you’ve removed the grass, the next step is to put down a layer of good-quality weed control fabric, such as Weedtex or Groundtex. It’s important to cover every inch of the ground where your deck will go. Leave a gap and it’s an open invitation to weeds to grow.
  1. Add an extra layer of protection. Once the weed control fabric is down and secured with landscaping pegs, the next step is to cover it with mulch or gravel. Put a good, thick layer down – both help keep the light out and suppress weeds and anything else that might grow.
  1. Wield the weed killer. Of course you might inherit a weed problem or not discover it until your deck is down. If this is the case, it’s worth getting the wield killer out and thoroughly treating the problem area. You will have to be persistent and it might take a while, but it could do the trick.
  1. Be vigilant. Whether you’re tackling the problems of weeds coming through your decking before or after installation, it always pays to keep an eye out for any weed growth and spend some time on a bit of maintenance around and below your decking if possible. Get to the weeds early!

Another tip for anyone dealing with weeds already growing through decking is to get the decking taken up. It might not be possible and it is a much bigger project, but once the decking is up, you can follow the first steps above and tackle the problem much more efficiently. If this isn’t an option, check out our top 5 tips for effective weed control.

Overall, it’s worth remembering that weeds can be maddeningly persistent and even the most thorough planning can sometimes come up short. But the more you do and the more you invest, the better the results will be.

We hope that the guide has given you ideas of  how to stop weeds coming through your decking.

I couldn’t be happier with my new fence! From start to finish, the team was professional, efficient, and attentive to every detail. They offered expert advice on the best materials and design for my property, and the installation was seamless. The quality of the craftsmanship is outstanding, and it has truly transformed the look of my garden. I highly recommend this company to anyone looking for reliable, high-quality fencing. Excellent service and amazing results!

GREAT FENCING!!! We asked Knight Fencing to run 4ft 6"double closeboard with 18" close diamond trellis around our last property (in Bedhampton). This was because we saw what a great job they had done at one of our friend's gardens (in Southbourne). Then another friend saw what we had installed and Knight Fencing did the same for them at 6ft 6" around 3 sides of their back garden (also in Bedhampton). We then had the bottom of our garden re-fenced with 6ft 6" double closeboard when we first moved into our new property (in Purbrook). We are now ready to have the rest of the garden re-fenced and have no hesitation to call Knight Fencing again. Any time anyone has seen these 4 fencing jobs they only say what strong, professional and quality fencing it is.

Thank you to Shane and the lads who recently erected my 2 metre fencing.
The lads worked hard even though the weather was against them.

Thanks again. I will definitely be using Knights fencing in the future.

Terry from Knight Fencing completed a 22m 6ft high fence and gate installation for us in April 25. From the initial quote Terry went above and beyond to suggest clever solutions to how we wanted the fence put in, eventually helping us to settle on a trellis to keep the view from the end of the garden. When completing the work he and Sam arrived promptly and worked so hard all day to get the work done. They have done an incredibly professional job, the fencing looks fantastic and they left the garden, if anything, tidier than it was before they arrived! I would highly recommend them and thank you for doing such a great job, we can now enjoy the garden without worrying about our dogs escaping!
