If they haven't went to seed I just throw them back down or under some mulch and let them rot. If they have mature seeds then I bag them and take them to the dumpster. Grass burrs unless no burrs have formed always go to the dumpster. But on most weeds they are put to good use recharging the soil. Of course the tumble weeds blowing in this winter brought enough seeds not sure why I'm worried. Will have to keep the mulch on this year. Jay

Like above, if I get them before they make seed heads, I use them, but I use them in the compost pile.

Otherwise, they go in the garbage along with all bermuda grass roots.

You can place them (seedless) on top of the ground, preferably under mulch so they won't look unsightly, and let them function as mulch until they decompose and turn into compost that will feed the soil. I do that a lot in the veggie garden.

Or, add them to your compost pile. Your compost pile should get hot enough to decompose the weed seeds.

Some weeds are what is known as dynamic accumulators--they are able to pull up certain nutrients from sub-soils into their roots and accumulate those, so letting them decompose to put the nutrients back into the soil is a great idea.

Bermuda grass roots or stolons always go into the trash though. I don't need for bermuda grass to start growing in the compost pile. I have enough problems with the invasiveness of bermuda without letting it loose in the compost pile.

I use it all as mulch, just be sure its dead! If I'm weeding things other than bermuda... I simply turn it upside down and leave it there. If that's not visually appropriate I dump it on top of existing mulch, it will die by itself. Bermuda I dump in a pile where it it dry out and cannot route. When I know its dead, I go back and mow over it and let it be mulch.

Thanks so much. I will put them back on the ground around my plants. I never put in Bermuda grass, even though our front lawn is that, and i dug up dandylions and threw them in the garbage. I am sure they will come back since I didn't get many roots.
