Weeds between the Stone or brick walkway? What do you do?

Hello
I just weed wack them and they came back so quickly!!
This time I did pull some by the root, but the other ones I burned with a torch. Does this help or is there a much better way?
Does Roundup work?
Any good tips?

 

RoundUp

 

Ortho ground clear or roundup.

 

This^^^

 

for broadleaf, add an ounce of 2,4, D

 

What is that?

 

2,4-D is a herbicide that kills plants by changing the way certain cells grow. 2,4-D comes in several chemical forms, including salts, esters, and an acid form. The toxicity of 2,4-D depends on its form. The form also affects what will happen to 2,4-D in the environment and what impacts it may have, especially on fish. 2,4-D is used in many products to control weeds, and it is often mixed with other herbicides in these products

 

There are a few types of roundup. Some only stay active a short time. You want the 365 stuff.

 

Burn them. No chemicals

 

Last night I used the roundup on the burned roots that I found in my garage so between burning and this, I will see what happens.
Thanks everyone!
My friend said use it in the evening so the hot sun would not dry it to quickly.

 

This ^ ^ ^.
Regular Roundup will kill the weeds, but they will be back in 2-3 weeks even bigger and badder!
I use Groundclear...but anything with a residual effect will keep 'em down 3-6 months.

 

I weedwhack them down, and then let them be. With a little mindset change, they become a feature rather than an annoyance.

 

Yes...my mindset has been changing gradually over the years...we have a lot more "features" in the landscaping than used to be...the former owner is probably rolling over in her grave, she was a huge garden club nut...had pics of the garden in the local paper more than once.
The attitude I have now is to just do what we can, and if we can keep things from getting out of control...good enough.

 

My son uses a mix of vinegar, salt and dish soap. Can get the recipe online.

 

How about a nice chemical free weed killer? Electrocution!
Weedinator! The new pesticide-free way to clear your garden. But beware... it packs as many volts as the electric chair | Daily Mail Online
Does this sound shocking?
Same voltage as the electric chair!
One slip and it can boil the blood in your veins to 248 Degs F which is fatal!!

 

Your best bet is to get a generic roundup with at least 41% active ingredient. Like TurboDiesel said mix a little bit of 2,4,D in with it. Get the amine formula. Just keep away from any desirable plants. The 2,4,D is for broadleaf weeds. A surfactant added to your mix will give better results. If you know any farmers around you ask them were they get there chemicals.
EDIT. Whatever you get,READ THE LABEL!

 

I believe Roundup is systemic and really only works if applied to growing foliage.
I'm avoiding chemical weed killers and plan to try a torch soon (in the spirit of the forum and pyros everywhere).
Any tips on that would be appreciated.

 

My friend uses a torch but it was not enough so he recommended roundup after using the torch.
So that is what I did.

 

Straight vinegar kills most plant and environmentally friendly, and cheap
