Beekeeping is a very enjoyable hobby or small business. Honey bees can be as simple or as complicated as you want to make them. You can keep them just to pollinate the garden and watch the bees,or add supers to make a honey crop to enjoy or sell. Each honey super holds 40 pounds of honey. A good location will fill 2 or 3 supers and pay for the hive.
Beeswax candles add profit or make great holiday gifts.
Liquid Honey can be produced with or without an extractor. Or just enjoy natural pure comb honey. It also gets you outside to really see nature at it's best. Great exercise also. This is a hobby that can pay for itself or turn into a small beekeeping business part time.
