Patio/drive Weedkiller

[BJS]

What weed killer have people found to be the most effective and long lasting for patios/drives.

[janbee]

NONE of the ones advertised and that claim to kill roots etc. I just put down bleach and boiling water.

Sodium Chlorate if you can get it.

Have a feeling that it is not still for sale nowadays.

[woofgang]

Pathclear is as good as anything.

Sodium chlorate is the best that I have used. It can still be had (so I'm told) online. It comes from Turkey. I have used Glyphosate ever since S. chlorate was banned, and it's OK. I apply it twice a year on my gravel drive: end of Feb, and end of June. Apart from one or two weeds now and then, I don't have any weed problems.

I would give BAYER Garden 1L. GLYPHOSATE CONCENTRATE a go I always use this since my usual weed killer was withdrawn from sale.

I bought my last lot from Amazon using Pantiles Nurseries cost £9-75 which was the cheapest price I could find at the time however I believe it can be obtained at any good garden centre, but maybe not as cheap.

I use a solution made from soda crystals, 99p a bag from my local chemist, with a squirt of detergent, which acts as a wetting agent

Professional RoundUp via Google, but do NOT get it on your grass or flower beds.

It'll be around £50 for 5 litres, but well worth it. One application a year should solve your problems.
