Hi Peter and All
During oxalic drizzle treatment late in November I have found that if
a hive has less than 5 seams(space between frames) occupied by bees in
cluster, the colony will not survive the winter. Last year was the
coldest winter remembered here and only colonies with 6 or more seams
of bees, at oxalic time, survived. How does Peter's 18,000 relate to
my 5 seams?
