What's the Best Economical Grass & Weed Killer?

[Appletax]

What do you recommend? I have tried vinegar, soap, and salt, but I want something more potent. 20% vinegar would be perfect but it's too expensive from what I have seen.

Edit:

I am going to get this concentrated killer and this sprayer. It's not environmentally friendly but it will get the job done real good and real cheap. Using 10oz of the weed killer per 1 gallon of water will make 12 gallons of strong weed killer for $20.

Boiling water is the absolute cheapest thing to kill weeds.

You can torch weeds.

Vinegar + Salt + Dish Soap may work. I think boiling them would give you the ultimate economical and environmentally safe weed killer.

If you want an eco solution use boiling water

I found the Garden HotZot, a piece of equipment that boils water and lets you spray it with precision, but it's $200. Would be nice to find something like it with a smaller price tag.

Best economical or ecological? Economically, anything with glyphosate (ie Roundup) in it is the most economical.

I found a concentrated weed killer that makes up to 85 GALLONS of weed killer for only $20. Pair with a sprayer for $13 and you're good to go.

Edit: realistically, you'll want at least 6-13 oz of it per gallon so it's more like 25 gallons or less.

Looks like it's $120. I like the idea for our garden. I'll have to keep an eye on this.

...and before we get too excited about glyphosate, it sits on the EPAs chemical danger list slightly above baking soda but lower than Tylenol (acetaminophen is know to cause liver damage).

If you live in the city I do, the drought we're having.

I saw a post on Facebook earlier in the week.

It mentioned a bottle of Apple cider vinegar, together with epsom salts.. Approx ½ cup full.

Mix these 2 up in a spray bottle (basically shake it), and spray on the weeds. The weeds are dead and gone within 24 hours.

Unsure of this though.. So please take it with a pinch of salt.

Table salt. Use it all the time in the paving cracks. Works a dream

You can get a 25KG bag of "rock salt" for peanuts. Mix a cupful with 5lt of water and pour/spray it on. Works for me!

Maybe boiling vinegar + salt + soap would be the most effective economical weed killer

Nice science @Appletax. Very well investigated.

And fire? - Hmmm.....not so much. I burn yearly out by my garden. Just makes the grass/weeds come back greener/stronger. With fire no roots are killed and fertilizer is created.
