If you spray Weedol in an area how does it not kill actual plants?

Question

surely they are more or less the same?

Answer 1

Weedol will kill any plant if you spray it onto the leaves. After all, a weed is just a plant that's growing where you don't want it to. You just need to be careful to only spray it onto the plants you want to kill.

Answer 2

I am confused by what you mean when you refer to "actual plants" -- weeds are "actual plants", they're just ones you do not happen to want to grow in a particular place.

Answer 3

Some herbicides are selective. I don't know the active ingredient in "weedol" (I'm in Australia). Glyphosate is used commonly here. It is a systemic, non-selective herbicide. There are many others available which are selective. The maker of the product should be able to give you all the details.

Answer 4

Weedol will kill plants, it doesn't poison the soil so you can plant immediately after spraying. A weed is a plant growing where you don't want it to. You can spray it around the woody stems of roses or shrubs, not on the leaf.
