The blackberry flow tapered off but it was a good one, I think. See below for a summary of June nectar flow. Japanese knotweed began to bloom in very sunny locations, where it was not cut earlier.

•Japanese knotweed (Fallopia japonica aka Polygonum cuspidatum]: one of our major summer nectar sources. It is an extremely invasive perennial plant, up to 12’ tall, with reddish, hollow stems with nodes, large oval leaves, and erect clusters of small, creamy-white flowers. It has a long blooming period and usually peaks in August.

•Panicled hydrangea (Hydrangea paniculata): a medium to large sized ornamental shrub with oval, dark green leaves and upright, conical clusters (to 6-8” long) of white sterile flowers and non-showy fertile flowers. It was one of my bee’s favorite pollen sources last July.

•June 2019 nectar flow recap
Apparent peak blooms came around 5/28 (black locust), 6/8 (tulip poplar), 6/15 (blackberry in sun), 6/25 (blackberry in shade or mown earlier), and 7/1 (linden). My stronger hive had a Broodminder hive scale. Its most productive 3-day period was 6/11 - 13 (gained average 5.5 lb/day), and the 7-day period was 6/26 - 7/2 (gained average 3.4 lb/day). From this hive, 23 lb honey was extracted on 5/27 (maple/hawthorn) and ~25 lb on 6/30. Will do at least one more extraction later. My hives are in a half-shade location. Within two miles are woodlands, wetlands and residential areas.
