What can I use that kills weeds but not my other plants?

There isn't anything home made that you can spray that will harm one but not the other. Preen products can do this. The other option is a vinegar weed killer applied with something small like an eye dropper.

There is nothing but to hand pull out weekly and mulch.

Hi Jessica,

I use vinegar in a spray bottle in a very targeted way in my garden. So far, my plants are fine. Just be sure you get it on the weeds, not on the plants. Do it on a day that is not windy because the wind can carry the vinegar to the plants. Even if a little touches a plant leaf, it won't kill the whole plant, but do be careful. Wishing you the best.

HI Jessica!

Here are some ideas! Good luck to you.

I have resorted to placing pieces of cardboard out on top of weeds or unwanted groundcover-in the flower garden on top of weeds but not covering flowers and placing mulch on top. It works very well for smothering out unwanted vegetation
