My flow starts mid May in a good year, so think now is about right to help them out. So many bees at the hive entrance with little flecks of pollen, clearly trying hard to find some. I noticed last year just how many dandelions are around in April but like you don’t build them up for those alone.Oh I was so tempted too. I would love some dandelion honey and we have masses of those in April...fields full. but if I'm trying to build them up for that I've missed the boat.
