I have 25 colonies and spend no more than 3 minutes on inspection per hive every 9 days (all my queens are marked and wing clipped ) during the active season but if anything needs sorting out (artificial swarm, setting up nuclei etc this can take up to 15 minutes per hive). Too many beekeepers open up their colonies far too often for far too long when such exposure and disruption isn't necessary. Once bees are fed etc for winter by end of september I don't check them again til April apart from a december Oxalic treatment for Varroa and monthly checking their weight in February and March to identify any shortage of stores.
I would think a beginner with 3 hives needs to spend no more than 1 hour per week during the active season on their own bees but allow more time for looking through other hives with other beekeepers to get as much experience as possible in your first year or so. Extracting and bottling honey can take a bit of time if you do well.
well yes but a beginner takes longer to do things that an experienced beekeeper does quickly due to practise and knowledge of what they are looking at /for.
When I started in 2010, watching bees in spare time was fascinating..And inspections were fascinating and a learning process.And finding an unmarked queen was a challenge. And everything was new to me.. so a learnng process.
And having more than one hive as I did, just meant more - and I wrote lots of notes.
Now I do quick inspections, check for disease with a practised eye and can find unmarked queens reasonably quickly . But that is all learned expertise from 9 seasons of inspecting my own and Association Apiary hives. (and building much of my own kit being mean).
So I would say as follows: (for 1-3 hives)
In winter - with bees - about 2 hours in total Oct-March mainly Oxalic Acid in Dec?Jan and walk pasts to check for wind damage. And a quick weigh/heft to check bees still have stores
In spring - 30-40 mins/per hive per week March- April-May. If your hive swarms, add more time to catch/house.
In summer - June-July -Aug. Adding boxes for honey etc.. gradually reducing time on inspections as swarming less likely.
August - honey crop could be nil to several hours if you have lots.
Late Aug-Sept -October ..Very little apart from feeding..And varroa treatment. Done competently not much after early Sept
The more hives you have, the less time you can spend on each and you streamline what you do.
If you raise nucs add more time.And if you raise queens then it means working to a fixed schedule and can be very time consuming depending on how you do it and how many..
And if it's a hot summer like this year , you do as little as possible due to turkish baths in beesuits..
Beekeepers who go on holiday May/June without having a hive sitter for them face the risk of losing half their bees swarming and all their honey crop.
