Chamberbitter (also called mimosa, gripeweed, niruri) germinates when temperatures are warm, around 70 degrees F. You would need to apply Gallery 75 DF at the rate of at least 1 lb per Acre (0.38 oz per 1,000 sq ft) to prevent this weed from germinating. You can reappyl at 60 day intervals as needed, as long as you do not exceed 4 lbs per Acre per year, per the product label. The only temperature restriction we would recommend is that you should not apply pre-emergents when the ground is frozen, near freezing temperatures, or water-logged. So if you make a February or March application, then you could reapply at least 60 days from that.
Another great tool to help prevent this weed in ornamental beds is to keep a 2-4" layer of mulch in the beds to prevent these seeds from being able to germinate. Here are some articles with additional relevant tips and information:

Unfortunately, there really aren't any options for selective post emergent control of broadleaf weeds in sedum or most ground covers. The chemicals that would eliminate the weeds would typically also harm the ground cover. You will need to carefully spot treat or hand pull the existing broadleaf weeds, and use a weed preventer in spring and fall to help keep them from coming back. Gallery 75 DF or Isoxaben 75 WG would be the best choice as a pre-emergent if you are targeting broadleaf weeds in a sedum garden or in a cool season lawn.
