We went to see Tim Ives speak in northern New Jersey on March 15. He mentioned "fat bees" and stressed that it is important the bees eat only real honey, no artificial feeds at all, and that they go into winter with three deeps packed full of honey, pollen and bees.
Not sure if Tim is aware of how Dee manages her bees but the idea of the bees only eating real honey and pollen and overwintering in three deeps packed with real food, looks almost exactly like Dee's hives. (Dee will swap capped honey frames with extracted wets during a flow to open up space for the queen to lay but makes sure the third box is full of capped honey before winter...otherwise does not take anything from the third deep down.)
WRT trees, he had never been east before and couldn't believe how many trees we have. His "trees" are narrow strips at the edges of cultivated corn and soy. By overwintering hives with huge resources, his bees build up even bigger on the very early weed blooms in the cultivated rows.
Many questions after his presentation and much from New Jersey locals who said their flow patterns prohibit Tim's management. He laughed and said that that is exactly what other beekeepers in his Indiana area say, that it is impossible to do what he is doing.
