What other people spend on their lawn/fields I don't consider any of my business. Weeds are extremely successful at reproducing themselves. If you have a lot of weeds in your lawn, they will also be in your veggie garden, flower beds, driveway, potted plants and your neighbors yard. I don't have time to devote my life to pulling weeds from where they are not welcome. I don't have 11 acres, only 4 but keep the lawn around the house, about 2 acres, pretty decent. (keeps the deer tick numbers lower) I also have areas that are planted with white dutch clover, wildflowers, fruit trees and completely wild wooded areas. My bees do not get to veto how I maintain my property. (I guess that they do influence though) Do I consider how an action will affect my bees? Absolutely! I will not harm my bees because there are ways to take care of landscape problems without doing so. Do I spray my 15 fruit trees? Yes if I want any fruit at all. But I never spray during bloom or even if there are a few late blossoms. I've never noticed any bees on the lawn while I was spraying for weeds, and I look. I spray 1X per year. Mowing usually keeps flower stalks to a minimum. I do have about 1/4 acre section of lawn that has a lot of clover which I allow to bloom. When it slows, I mow it to encourage another flush of bloom. I do the same with the nearly pure patches (2) of white Dutch clover mentioned above, alternating mowing with the lawn clover to keep some available as long as possible. I would guess that more bees would be killed mowing a grass/clover lawn than by weed killer applied properly. Even that could be avoided by mowing when the bees are not flying, if we can manage.
