Prevent & Kill Block Paving Weeds

How to kill and prevent weeds on block paving.

Why are weeds growing on my block paving or patio?

Regardless of what your builders told you, there is no such thing as a weed free surface.

Forget what you've been told about weed control fabric. It can help but if your paving is built, maintained and cleaned properly it's very rare to see weeds grow, except maybe the notorious Japanese knotweed and some forms of Mares tail.

If you allow muck and dirt to accumulate on your block paving it won't be long before the weeds begin to colonise it. 

In the end weeds grow in or on block paving because of the laziness of householders.

Just like a car, paving requires cleaning and maintenance, do both and you should be able to prevent weeds from growing in the first place. Do only one or none of these things and you're going to have a problem.

If there are gaps in your paving stones or you have allowed dirt to accumulate on the surface, weeds will grow & thrive.

My third horsetail invasion.

This is my third attempt at killing horsetail, unfortunately having just bread even more literature regarding this triffid I realise I am attacking the problem too early in the season. I will have to wait until late summer to try again and see if the results improve. Not yet.

Annihilates the most obdurate unwanted plants

Keeping a back alley free of all vegetation and quelling ivy growing on a garage that has resisted all other weed killers over a 40 year period. Additionally used to keep a large paved area clear of weeds It was extremely successful. The killing of the ivy was the most gratifying as it was so effective. All other weeds perished too. This is an excellent product.

This time i used on stingers in my neighbour's and own rear gardens because of rain they had griwn to 3 feet. Also did smaller weeds on front drives. You need patience. After a few days you think it was a waste time, but then you notice the leaves have started to drop and after a week you can see them dying. Going to do my sons garden today. Will purchase again

I used the weed killer in all different types of weeds. I have a gravel back yard and it was full of wee weeds. I am 72 now and weeding is becoming harder for me. I made a note of when I put the weed killer down because I knew from last year that your weed killer takes a wee while to work. I sprayed the weeds on 30th May. Today is 16th June. The weeds are completely dead. I also sprayed an area at the front of my house under a big tree.I also did my front patio and gravel at the side of the house. My daughter who is across the fence from me had a large nettle growing beside her daughters trampoline and I’m sprayed this, just wondering if the weed killer would work. It did. Nettle black and I need to pull it out now.It was extremely successful. When I was spraying my neighbour said to me that weed killers don’t work well nowadays, they are so “environmentally friendly” that they don’t even kill the weeds. Well I think Rob will have toe at his words! I am very, very pleased with the weed killer, in fact I am going to be ordering more today or tomorrow. many thanks. Winnie.

Barring the infamous Japanese Knotweed almost all other kinds of weed can be dealt with easily & quickly.

What to try first:

By far the most popular method of removing weeds from block paving is manually.

On a small area this can be completed in no time and is highly effective, all you need is a hoe or gardening knife.

Simply pull or scrape the weeds using a hoe or similar.

Make sure you get the roots, Perennials like daffodils will regrow from anything you missed!.

When removing weeds with large roots some of the sand or sealant may come away. You should replace this once you've cleaned the surface.

Partially filled or empty joints will be quickly colonised by a new set of weeds. Fill those cracks!

  • Weed killer: It may not be everyones favourite method but there are numerous safe formulations that are highly effective against block paving weeds.
