Who knows when it will go to seed, depends on when the seeds germinated and how aggressively it has grown and allowed to mature. Seeding can typically take place from mid-summer to fall in areas that have a true winter.
I can't imagine it would take you that long to pull all of that area. Once you do that, you should be able to nab any stragglers and next year will be much better as you stay on top of it and get that grass thicker and longer.
the point trying to be made by riggle is that the plant will not live through the winter into next spring
Keep it from seeding
When you pull it up you are only exposing more seed to germinate, it may look better but you have just set the table for more crabgrass germination next year
and BTW it is called edging not scalping
