Will vinegar and hot water kill grass around plants without killing plants?

Answer 1

The hot water, if only contacting the grass will not hurt the other plants, although the desirable plant's roots may extend beneath the soil to where the grass is. As for the vinegar component, also take care that it does not contact the roots or foliage as it works by stripping the protective coating from leaves. It also temporarily acidifies the soil, which is undesirable for most plants except the acid lovers such as azaleas. I wouldn't be using the treatment very close to other plants. You could try spraying the grass with vinegar only, shielding the good plants well, and don't do it on a windy day. If you have used household vinegar, this should break down in the soil within two days. Water the plants well, without washing off the vinegar from the grass.

Answer 2

Yes, a mixture of vinegar and hot water can be effective in killing grass around plants. However, it is important to be cautious and precise in applying the solution to avoid contact with the desired plants, as vinegar is a non-selective herbicide and can harm them if not used carefully.

Answer 3

Vinegar is acidic. Many plants must maintain a balanced pH and would be negatively affected by the vinegar causing the pH baseline to turn acidic. Water does help grass grow, however.

Answer 4

Yes it actually will in 4 days.
