I must be missing a trick Here’s a quaint apiary I came across where the ivy is in full flow and there are still several supers on. Mine came off before the ivy flow starts and varroa treatment commences.
Well ... if they are taking a crop from the Ivy they need to get it off and spun out very quickly because it sets like concrete ... more likely someone who has not yet bothered taking their supers off - in fairness, mine only came off last week. (Very late this year I have to admit).
