Lack of rain and deer have hurt me this year. Electric fence is not keeping them out this year so we did a combo of plot saver and spraying all of the sunflowers with this stuff last week: https://helenaagri.com/our-expertise...rch/trico-pro/. It's only been about a week but it seems to be keeping them out. We had to replant about 20%. Those late sunflowers probably won't make by Labor Day but hopefully we have enough time for them to develop fully.
