Siberian Iris Care
Growing Siberian Iris is not a great learning curve, the long lasting flowers followed by attractive green foliage in an easy care plant make it a good standby plant.
Tolerant of wet soils they are ideal for some of the more difficult spots in the garden. Dormant in winter they will spring back to life as the weather warms up. They do require good sun and will not flower well in shaded positions. A humus rich soil is best.
They are smaller growing than brarded iris, however larger than pacific coast iris, so they fill a spot in the garden height wise as well. Typical iris blooms with falls and sepals. Height will range accorcomg to the growing conditions and the cultivar itself. Generally ariub .6m (2 ft).
Dividing Siberian Iris.
Over time Siberian Iris will form a large clump, to promote vigour you will need to divide them. This will be required every 4 - 6 years. As soon as the flowers become a little less impressive its time to dig and divide.
You can do this at any time during dormancy.

Siberian Iris Care
Moist soil is the key to good growth and flowers. Siberian Iris will require water during dry summer periods.
If you have prepared the soil well, lots of good compost and humus dug in before planting you will achoeve two things, the required moisture retentive soil and a fertile growing medium.
Do not be tempted to fertilize with a nitrogen rich fertilizer unless you are after foliage growth and no flowers. Any fertilizer is best applied after flowering rather than before.
