My idea would be , using the tiller to make some opennings of about 25 ft apart ( maybe 2 passes ) allowing the Sun
to heat the ground , plant these opennings , leaving the old growth for security for the birds . Next year , work on another
part of the old growth , plant a little more . This will encourage more birds to use it and in no time , it will be a wonderland
of opportunity for you and the Birds .
Thanks for thinking about the Birds
PS , Make sure you think about the wind !
