I think you would be find, as I feed mine on a daily basis and it is only 1/4 acre at the largest. This will be my 3rd year and I have not had too many issues. Last year the FA was pretty bad but it had started before I was feeding.
This year it has not hit yet, so not sure what is going on, I am not complaining but I just new with all the issues people are having this year with the mild winter mine would be completely covered.
Maybe the GC are eating some of it, or the sun can not penetrate as deep this year.
