Hey guys I've got an Ag question regaurding planting for waterfowl.

So i have drained down my 5 acre pond and exposed 5-20ft mudflats around it. I planted Japanesse Millet back in the middle of july to be ready for the early season. If all the millet matures out what do i do to get the millet to re-grow for the late duck seasons?

I now realize i should have planted in sections each a week or two later than the next (next year)

Do I:

1- weedeat areas to reseed
2-reseed more millet in with it now
3- or let it hopfully re-seed its self for Dec. and january hunting
