Can I spray roundup to kill grass around 3-year old crepe myrtles in order to mulch later?

Would it affect the trees or just the grass? I want to spread mulch around each tree base but before I do I'd like to kill the grass there. Will this affect the trees at all or just the grass?

Spray very lightly. DOnt soak the ground like you would on a fence line.
Also, if you plan to mulch, you don't need to spray at all. Get old news paper and thickly cover the ground around the tree. Wet the newspaper, and apply the mulch

This. Cardboard would also work great.

Never heard of that. Interesting and thank you!

Ha! You can pour round up directly over crepe myrtles. Good luck ever getting rid of them if you ever want to! Those shits refuse to die!

Heck, I've cut one down before, dug it up, sodded where it used to be... and a year later... "Hello, remember me?"

You can soak the ground around them and it won't matter. Roundup doesn't work on roots, Roundup works on foliage.

I've been trying to kill one for years. Cut it to the ground, sprayed herbicide directly on the open cuts. It acts like I used fertilizer! I'm resigned to just cutting it to the ground every year.

Use root rot type stuff or even groundclear, but careful with amounts used if near other vegetation you want to keep.

Roundup will not hurt those trees but make sure it only hits the grass you want to kill and be careful of runoff if the ground is sloped by the tree. If it rains shortly after you spray, you will have the possibility of the rain water spreading the roundup into your lawn.

Will the newspaper trick work under a magnolia tree? Or will the surface roots get compromised by the newspaper?

I do this in my vegetable garden between the rows all the time. Head to Rouses, get a bunch of cardboard boxes, cut them to fit between the rows and then cover all that cardboard with oak leaves and grass clippings.
Keeps weeds down and the garden has less need for watering since the ground is protected from the direct sunlight evaporating the ground water.
