EDDDIEE,
I agree with wirehair, cut strips.....I do the same thing to a 5 acre field that has grown up for 2 years...This was suggested by our county wildlife management office also....They told me not to bush hog any until August 15th which is the end of nesting season.....

Bush hog a strip 15-30' wide and then skip a strip...The deer will feel secured with every other strip unmowed......In the future, alternate strips when mowing........They really like this native food plot.....It's cheap to grow too!
