Cultural Notes - Bearded Iris 
Culture of the Tall Bearded Iris is simplicity itself. The most important item being 
the preparation of the ground before planting. As Iris plants are usually left undis- 
turbed for a number of years after planting, it is strongly recommended that the 
soil be deeply spaded and a liberal amount of bonemeal incorporated. Bonemeal is 
a slow acting fertilizer; its effect will be noticed after the first year and will last 
for a number of years. Drainage should be provided as iris does not like its feet to 
get wet for any length of time. If the garden does not naturally slope, it is well to 
plant the rhizomes on top of mounds or raised beds. If the soil is acid, some lime 
should be worked into the ground. 
When the Rhizomes are received, plant them with the roots straight down and the 
rhizome horizontal and cover with an inch of soil. Pack the soil well around the roots 
and keep moist for the first two months, after which the plants should be able to 
take care of themselves with ordinary garden treatment. After the first season the 
rhizomes will lie on top of the ground and be exposed to the sun. Do not cover them 
with soil, as this is the natural way for them to grow. Plant them at least 12 inches 
apart, 18 inches is better, as it will allow space for the plants to spread for a number 
of years. Water well during the growing season if the seasonal rains are not adequate, 
and occasionally during the summer months. Cultivation should be shallow so as not 
to disturb the surface roots.
