When you don't use chemicals in you hives the object is for them not to die . If they die they will not become stronger. You will become poorer buying more bees that could die also. I don't use chemicals but 80% or better live through winter.
Buying commercial genetics would undermine my intention to raise bees naturally. I will only increase my hives via swarms, cutouts, and splits. I'll split survivor hives more aggressively than the swarm captures.
Honey would be nice, but I don't need to ever collect honey to be happy with my hobby. Any honey I do collect will go to my mead making hobby. So I won't make money anyway.
I expect lots of hives to die and to split the survivors. Then, fewer hives should die every year....theoretically.
I have had bees for 12 years now, never have used any chemicals and very seldom have fed them sugar water and have had pretty good success with them. I started with 2 hives and now have 18. Some years are great and some not so good. My friends who do use chemicals and feed sugar have had about the same success rate as I have. Why bother with the chemicals and why not go natural!
Nice to hear of your success with natural beekeeping! Thank you!
Have a wonderful day!
