Records of what you have done and what/when to expect in the future are very important. To that end I just finished copy and paste into a word document my 2010 beekeeping record calender from www.printfree.com.
A nice editable monthly calender to record any information you want to type in. Save it - email it as a document.
Record feedings, splits, bloom dates are important too for next years planning.
Prior years are a mixture of beekeeping and kids schedules written on a wall calender. It works but the beek in me wants my own records.
Thats one thing I havent done, kept records yet, but I really should start!
Seeing how im starting over this spring, its a good time to start!
