Just to remind all beekeepers once again, that the June gap has arrived and large growing colonies and nucs etc. with little or no available forage, can quickly suffer from a shortage of stores.
So be sure to check that your bees have enough food, especially if you have taken off any spring honey. Note that if you add extra frames of sealed stores you should keep them in the brood boxes, so as to avoid getting them mixed up in the honey supers. Also, if you have to feed directly, use a light syrup (i.e. 1:1 sugar/water ratio) with any honey supers taken off during the feeding process.
