Weeds are simply inconvenient plants growing in inconvenient places and there are few places less convenient than your brand new block paving or patio.
Firstly, 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.
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.
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!
If your block paving or patio is quite large or overgrown and you don't have time to dig/scrape them all out there are a number of homemade treatments that may help.
They may only work temporarily but are often a cheaper alternative to weed killer.
As long as you keep your paving clean and fill any cracks then it should be easy to keep the weeds away.
