It is very easy to make homemade sugar patties, especially the way my beekeeping friend David showed me.
David uses aluminum pie tins so I will start with those quantities. For one pie tin, either 8" or 9," pour 2 cups sugar into a bowl. Spray with 40 squirts out of a spray water bottle. Mix with a wooden spoon or your hands. Pack into the pie tin. Allow a couple of days to dry.
When using clear suet containers, you will need 1 cup sugar and 20 squirts of water from a spray bottle. Mix. Pack into a suet container. Allow to dry.
David said sometimes he adds a drop of lemongrass, food grade essential oil to each patty. I skipped that step in making mine.
The first sugar patties I made I dried in an oven warmed to 100F, then turned off. Not sure that is necessary unless conditions are very humid.
To feed, place in a top feeding shim under the inner cover to supplement winter honey supplies.
Once bees have a pollen supply from the garden they will stop taking the sugar. In the meantime, glad to be able to easily give my bees supplemental food so they don't starve at the end of winter.
