In the northern tier of the states and in Canada no less than 90-100 pounds of food is needed to survive from roughly October to May. In the southern states 65 pounds will usually stretch through winter to the start of spring when nectar begins to flow. In either case winters can be different from year to year. One year it could be a calm winter and other years it may be harsh. So with this being said always play it safe.
After you find out the desired weight to get your hive stores too, You should start by weighing your bee hive. This can be done with a set of heavy duty bathroom scales as seen in pictures below.
|Tilt hive to one side and slide scales|
|Now lift the opposite side putting all the|
weight on the scales.
|Now read the scales and get your weight.|
A second person can make this step easier but one can do it.
Once you know what your hive weighs now you can do a little math and see about how much of the hives weight is food stores.
