I am in mid-MD and the dearth is starting. I just added apivar to my colonies and noted, as in years past, that the top deep (whether a double or triple) is often full of capped honey/nectar. 10-frame deeps. Very difficult to move. We hear about feeding a little 1:1 to each colony each week during the dearth, but it is really necessary to feed 1:1 even to colonies already so packed with honey in the top box?
