Re: What are the limits to growth? Expanding apiary.
"supplement with sugar throughout the warm months."?
I think you have need for more years of experience before expanding too far too quickly.
I understand your great hopes and expectations. We all start out some time from where we are. "the greatest threat to the world's bees [is] still the incompetence of their keepers." Hannah Nordhaus on Langstroth's beehive in her book "The Beekeepers Lament". Which would be a good book for you to read if you would like to better understand "What are the limits of growth?"
Best wishes. Don't let my comments discourage you. As if that is all it would take.
