I just put down some weed kill (I'll probably spray again for good measure and to get rid of my wild onions) and I was wondering if after they're completely dead if I need to physically go out there and pull out the weeds, or do they decompose on their own without me having to pull out the roots. Thanks!

It depends. If they are in their immature stage without seed (heads), fogetta bout it..BUT if they have ANY seeds on them like Poa annua in the spring does, yank them out after the foliage starts to brown out and die. Don't wait too long though because the drier the seeds get, the more likely the seeds will dry and be dispersed. Good luck with the onions. Onions are sort of like Nutsedge, you pull them and they leave little bulbets in the soil which send up new plants. Even if you've sprayed already I would try to bruise/wound the onions, then apply herbicide (glyphosate) to them which should increase the uptake of the product. This has been my means of controlling the weed in my yard and place of work.. Many weed seeds will remain viable for a very long period of time (hundreds of years) so in the future, pull all of the flowers/seeds before they have a chance! Again, the most important thing with controlling weeds is eliminating the seeds (and seed bank). Remember: Glyphosate/Roundup does not kill the seed, just the plant Good luck.

If you have nothing better to do. That is the purpose of using weed killer, so you don't have to pull the weeds.
Just sit back now and watch the buggers die.
