Haven't thought about Starting Beekeeping Questions:
Q1: How much honey can you get from one hive?
It varies from hive to hive, year to year, area to area, beekeeper to beekeeper. In an ideal harvest, 100#s. But sometimes none. The record is over 400# (unfortunately not my hive). Beekeepers have a term "Subsistence Bees" which are colonies that need to be fed in the spring, produce no honey from the nectar flow, and then require feeding in the fall.
Q2: Do you feed bees honey?
The goal is for the bees to collect nectar, turn it into honey, and store enough extra that we can harvest the excess. Beekeepers may harvest some honey from a hive, store it, and then feed it back to the same hive in the spring. Generally, if we have to feed a hive to stimulate it in the spring or keep it from staving in the fall or winter we will feed granulated sugar either dry or mixed with water depending upon the time of year and conditions of the hive.
Q2A: Do you feed Organic Sugar?
I once attempted to feed the bees sugar water made with organic sugar...they spit on it! So, nope. I use good old granulated white sugar. And they drink it and they are very very grateful. Becaue then they are not dead. And that is my goal.
Q3: Is it true that eating local honey cures allergies?
If you believe that, I have a bridge in Brooklyn to sell you. Many people 'claim' to get relief from their allergies after regularly eating local honey. Perhaps honey coating the throat relieves allergy symptoms as it does in a sore throat mixed with tea. Maybe the traces of pollen in local honey tends to make your immune system less reactive to pollen. Maybe when adding honey to the diet, table sugar or high fructose corn syrup is removed from the diet and maybe that has an effect. Maybe all of these or none of these are true. I don't know for sure but it's really really good.
