I've been tossing up the use of bags when my vines start bearing fruit in a couple of years, as I'm trying to limit the use of pesticides as my yard borders a protected wetlands and we have a bazillion birds around the place. Given that I only have 90-odd vines, is there any other disadvantage other than labour? I couldn't care less how much time I put into anything to do with the vines, so are they worth it? My vineyard is a part of our backyard and there is an entertaining area beside it, so I'd rather not have nets over everything for a month and half every summer,
