| Crabgrass, not the readers. |
A. It is now August. If you correctly identified your weed as crabgrass, there is nothing that you can do
now except remove them by hand or do some hand weeding. Crabgrass will die when it freezes hard this
winter. If it is in a location where it does not freeze, or lightly freezes, then
it will survive and grow more the following year.

You can also burn them back if it is
allowed. Propane weed flamers or torches work well if you use them in an area
that will not continue to burn. The seed, however, will still be there on top
of the soil and unaffected. The seed germinates in the spring around the middle
of February in our climate or perhaps earlier if it is warm.

Pre-emergent herbicides or weed killers
can be applied about the middle of January to prevent crabgrass from
germinating and getting a foothold. It should be reapplied about six weeks
later or when the label tells you to. But this time of the year, all you can do
is pull, burn or dig them out.If you buy a pre-emergent weedkiller for crabgrass make sure it lists crabgrass on the label, destroy any crabgrass that survive past the end of January and apply this herbicide by mid-January in our climate.
