I have been using SBM/AM this year and it's been very effective (my worm population is going berserk in a good way though) I overseeded last week which is late I know and my question is this: is it too late to put down one last application of SBM/AM this week? I.e. Will it be too late/cold for the microbes 'to eat it up'? I do plan to put down a JG winterizer end Nov/early Dec

I live in western Mass
