I think we are 3 weeks behind as well. I still have clover, which died the last week of june the first 2 yrs i kept bees. I have lots of clover still. Oddly enough, my mint and hyssop bloomed earlier, but bees are ignoring it b/c of clover. Loads od nectar in frames but unsealed going on 2 weeks now. I am conscerned they will start to move it back into brood area as summer marches on if it doesn't get capped soon.
