Last year I bought an iris from an iris farm, The iris is supposed to bloom twice a year, in the fall and spring. It has been almost a year and still no blooms, but seems to me multiplying well. Should I did it up and transplant it to where it gets more sun, and is it okay to do this during this time of year? Any advice is greatly appreciated.

Poor flowering is normally due to planting in excessive shade, using excessive nitrogen fertilizer, or planting the rhizomes too deep. Limited flowering may also occur if plants become too crowded and need dividing. Irises sometimes take a year off bloom after transplantation to settle into their new homes so you don't get bloom the spring after planting.

Bearded irises can be divided any time after your last frost date in the spring, but the optimal time to divide them is 6-8 weeks after bloom. Avoid transplanting irises in very hot weather (90+ F degrees), but do get them transplanted back into the ground a couple months before freezing weather to give them time to root in well before winter. Irises moved before bloom will often lose their bloom that season, which is why it's best to wait until after bloom to dig and divide.

Iris will thrive in most well-drained garden soils. Planting on a slope or in raised beds helps ensure good drainage. If your soil is heavy, coarse sand or humus may be added to improve drainage. A pH of 6 to 7 is preferred.

Iris should be planted so the tops of the rhizomes are exposed and the roots are spread out facing downward in the soil. In very light soils or in extremely hot climates, covering the rhizome with 1 inch of soil may be desirable. A common mistake is to plant Iris too deeply.
Bone meal, superphosphate and 3-5-5 are all effective. A light application in the early spring and a second light application about a month after bloom will reward you with good growth and bloom. Avoid using anything high in nitrogen, as nitrogen encourages rot problems.

Bonemeal is a traditional fertilizer for bulbous plants that
releases phosphorus slowly, but it is usually too low in
nitrogen to be used alone. An additional source of
nitrogen must be used together with bonemeal. Wood
ash is an alternative way to supply potassium. For
average situations, apply 3 to 4 pounds of bonemeal and
5 to 6 pounds of wood ash to each 100 square feet of
soil.

Be patient. I have found there is about a two year time lag before they really start blooming. They like to sit a while and get established. I don't look for a lot of blooms on iris until they have been in the ground a full year and maybe another. They are tough and dependable but they do like to wait a bit before they bloom.
Blooms in the autumn? That is a new one on me.

properly I genuinely have iris and they bloomed in previous due march. notwithstanding those i planted in partial photo voltaic did,nt flower in any respect. they prefer properly drained soil. i imagine you ought to pass for complete solar, because very last 12 months too, they did,nt bloom because of inadequate solar gentle. The actual huge difference between those which flowered and those which donot became that flowery onesd had large foilage.merely you need to be affected man or woman. i'm certain your ones will bloom.

I think i can help!
The Iris is a flowering plant in the genus Iris, native to eastern and central Europe and northern Asia.

It is a herbaceous perennial plant growing to 50-120 cm tall. The leaves are glaucous green, narrow and fairly rigid, blade-shaped, 40-80 cm long and 2-4 cm broad. The flowers are typical of an iris, borne in late spring or early summer on unbranched or sparsely-branched stems held above the leaves, each flower 4-7 cm diameter, mid- to purple-blue, often with a paler whitish or yellowish center.

Cultivation and uses
Iris sibirica is widely grown in gardens in temperate regions around the world. It is the parent plant of many hybrids, used because of its attractive foliage and ability to flourish in a wide range of climates; the hybrids vary widely in flower colour.
