Most standard dwarf beardeds (SDBs) do quite well in my growing conditions. This northern MN zone 3b climate inflicts severe, extended cold during the winter months, often with little snow cover for insulation. The summer growing season is short with temps that sometimes exceed 90 degrees F. My soil is very heavy, compacted clay with a slightly acid pH, though I grow my irises in well-amended, raised beds or windrows with improved friability and drainage. A large local deer population frequently tramples and sometimes grazes on my irises in early spring and late fall. Iris borers are present but managed successfully with a granular systemic grub control product. Weeds are abundant and only occasionally beaten back by an admittedly lazy gardener (yours truly). Fertilization is inconsistent, when provided at all. Different beds range from full sun to barely 5-6 hrs of sun a day.

BILLY BOY is just another yellow SDB, albeit a reliable, tough little bloomer. Increase in average.
