Harvesting of honey varies for the geographic area. .
Sure it does. Like I have written last summer my hives took over 240 lbs from fireweed and 3 miles away another yard got about 60 lbs per hive.
On very dry sandy area 2 hives got not nothing.
It depends where you carry your hives when it is yield time.
Normally I empty my supers twice during July. At the end of August I take rest of honey when brood have almost emerged.
Now I am going to keep only 2-4 hives in one place. Before I kept 10 hives.
My main yield comes from canola and fireweed. I move to different palaces where I estimate to get maximun yield. To keep hives in one place is disaster.
If bees fly over 1 km, 50% of yild will be consumed as fuel. Last summer I had a place wher bees got full load inside radius of 500 meters.
It depends how you play your cards so often you are obliged to empty hives. - Sounds boring. :P
This year dandelions gived 50 lbs to 4-box hives. 2-box hives got nothing.Too dry fireweed area. Not good for bees.
