Would a solution of vinegar & water poured over my patio kill the grass and weeds growing between the slabs?

Answer 1

No. Vinegar will not kill greenery. Not even full strength.

A simple solution that I have used for years is to boil a full kettle of water, and pour that between the slabs. Then let it sit for an hour or so to soak well into the root system. And then just pull them out.

You have killed the weeds and grass with the boiling water. You have loosened the root system with the wet. And once you have all the weeds and grass pulled out, if you pour more boiling water into the (now loosened) soil between the slabs, there is a very good chance that it will kill all the seeds and small root bits left behind, and you won't have to worry about anymore weeds and grass growing back for a good long while (6 to 8 weeks).

Answer 2

Vinegar - effective for 5-20% solutions of acetic acid with higher concentrations most effective but mainly destroys surface growth and so respraying to treat regrowth is needed. Resistant plants generally succumb when weakened by respraying.
hi houshold vinegar is already diluted so no your normal vinegar wont work
you can buy path clear weed killer from most garden shops

Answer 3

Possibly...consult with a local greenhouse, or the gardener at a local public garden.

Avoid salt. It spreads, and essentially sterylises the ground. It can take years to reach a point where the soil can support "normal" plant life...and weeds tend to be much hardier where salt is concerned than the desirable plants.

Answer 4

Kettle of boiling water directly on the weeds. Environmentally friendly

Answer 5

Don't think so. Use a glycophosphate spray.Will sort out the grass and any weeds as well.

Answer 6

You can also pour a kettle of boiling water on the weeds.

Answer 7

if its just the odd weed here and there i use the water that i strain from a pot of boiled potatoes as i have to be careful of weedkillers because of all the animals roaming around the garden

Answer 8

no, you are better trying to get hold of the sand they use on the roads during the winter and brushing it between the slabs

Answer 9

Acid not strong enough. If it were that simple, these weedkiller manufacturers wouldn't be doing such a booming trade. You must be a misguided environmentalist.

Answer 10

Jeyes Fluid and water.
