Queen Bee
My bees are working flat out on the ivy and still taking syrup . Rapid feeders may be a better idea than contact feeders at this time of year ( the bees can then choose wether or not to take the syrup and they wont get a drenching thats possible from a contact feeder as the vacuum loosens when the day warms up ) but I certainly wouldnt be going round telling people that their too late for feeding !
I agree,as long as the bee's are actively collecting nectar from nature, then it's obviously not to late to feed,or the bee's would not be doing it.
