Block paving & weeds

Hi all,

Hope everyone is managing with the hosepipe ban.

I’ve decided to tackle our block packing which is packed with weeds and moss between the bricks.
I wondered if anyone could recommend a strong weed killer? The block paving was down when we moved in and isn’t new and does needs some TLC so thought if start with the weeds.
I’ve tried the usual off the shelf weed killers and they’re it effective.
Thanks in advance.

Then a dose of Wet and Forget.

 

The weeds in my block paving are actually grass, my having overseeded the lawn earlier this year. The roots are tenacious and it is impossible to pull them up. In this hot spell, I watered them with boiling water and now they are all brown and look dead - but still impossible to pull up, even with a weeding tool. Any suggestions to get rid of them would be appreciated.

 

I'd be strimming them off

 

How about a weed gun to frazzle them?

 

Weedol Pathclear - kills all plants and prevents germination of any seeds for between 4-6 months.

 

I use glyphosate at 3 monthly intervals. The main problem with paving of any kind are the seeds which wash into the crevices and are invisible.
