A rule that tends to be true in most human endeavors is <minimal effort ='s minimal results>.
This rule also applies to beekeeping except under a certain circumstance. That circumstance, is that the beekeeper is uneducated in the ways of bees, and on average does more harm when he opens the hive, than good.
So, how does the beekeeper become educated in the ways of bees? By spending time with the bees of course!! Opening the hive, seeing what bees do, learning. In the beginning will probably make a few screw ups. But it's learning.
Leave it alone beekeeping works, until it doesn't work. Which will bite nearly every leave it alone beekeeper eventually.
