Re: Is June too late to allow bees to raise their own queen?
Since the queen cell is capped she will hatch in a couple of days, it can take another week for her to take a mating flight then another twenty one days before the first workers hatch. It will take a week to obtain a queen form a supplier, four to seven days for the colony to accept and release her then same time for her brood to hatch. You will be ahead to let them raise one of their own.
Is June too late No. I make splits in June and get surplus honey by late August.
The Busy Bee teaches two lessons: One is not to be idle and the other is not to get stung.
