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 pr... read more
