What's the best weed killer in shops now?

[Sonak]

Hi all, I want a weed killer that will get rid of my garden weeds and won't grow back. Any suggestions? Thanks

I would suggest that to dig them out is best! You'll save money. won't kill off beneficial insects like bees and you won't be left with an eyesore of dying foliage.
If you do spray please do it at dawn or dusk before or after the bees are out. Midday is the worse time.

If you find such a weed killer it will either be illegal or ineffective in killing all weeds. Remember, a weed is just a plant growing where you don't want it. Here in the U.S. and I suspect, the U.K., one of the most effective and environmentally friendlier weed killers is Roundup. The problem is that it's a post-emergent chemical, meaning it won't kill weeds that will come from seeds already in the soil. Some people try to use pre-emergent types in the spring, but these have limitations as well. Often it's better to use a selective type, such as those that only work on broadleaf plants so at least the grasses will survive... a lot to be said for Tallulah!'s approach...
