Distillation - Dutch iris , or ksifium , - the Iris
Iris belongs to the family Iridaceae.It is widespread throughout the northern hemisphere.Thanks to the beautiful colors of the original form iRis.chen popular.Iris garden forms a lot.Most varieties rhizomatous irises belongs to a class of bearded, traditionally called German.
Usually flowers have three inner petals (or rather, perianth petal lobes), which are directed upwards, forming a set, as well as three external bent downwards.Outer petals in shape and color differ often from internal.The flowers are collected at the top of the flower stalk (2-5) and revealed gradually from top to bottom.
different varieties of irises flower stalk height and shape of flowers and their color and flowering periods.
There are not only rhizomatous irises.In recent years become very popular iRis.ukovichnye so-called ksifiumy (Xi-phium), from the Greek word meaning "sword" and iridodiktiumy (Iridodictium) - in Greek "iris mesh»,

Dutch irises have long, relatively broad lanceolate leaves.Flowers large diameter
This type can be cast out at almost any time of the year, provided that the bulbs are properly prepared.At a temperature of 25-35 ° C Dutch iris bulbs are dormant (all processes are slowed down very much), so they must be kept all year round.And it will not affect their quality.
Dig the bulbs in the first decade of August, and 2- 3 weeks stored at a temperature of 35 ° C, and then lowered to 17 ° C, and another month kept in such conditions.At this time, processes occur in the bulb, which lead to the formation of the flower stalk.The preparatory process for the formation of flowers embryos 4-5 weeks continued in the bulbs, and at this time they need a temperature of 9-13 ° C.Usually by mid-November, the flower buds are already formed completely manage.
In areas with mild winters can expel iRis.ryamo in the open field, in the more northern - in greenhouses.From December to April the bulbs are planted in the greenhouse for
8-10 weeks before the scheduled date of flowering.To get the blooming irises.May-June, the bulbs are planted in open ground in October and November, and to get the flowers in July and November, the bulbs are planted in March and August.In spring and autumn ridge with iris closing film.
In winter distillation take bulbs with a circumference of not less than 9 cm. For cultivation in the ground with flowering in May and June, you can use a bulb with a circumference of 7-8 cm. Smaller fit for Pozdov-growing non-flying.For summer flowering requires larger planting material (14 circumference greater than 10 cm).Embedment depth varies depending on the timing of
distillation.On distillation in December and April, the bulb is only slightly deepened into the ground, in other cases - close up 6 ~ 8 cm
Primer for forcing irises should be easy and a good structure..Recommended mixture of sod land with sand and peat in the ratio of 1: 1: 1.Dutch iris bulbs are very sensitive to salinity, so the soil should not be enriched with mineral fertilizers.Florists Europe even washed pound, if you have to put iRis.osle vegetables (tomatoes, cucumbers).
distillation temperature is very important, especially in the first two weeks after planting the bulbs.To flowering occurred in December and January, in the first two weeks, the temperature should be about 13 ° C during the day and night, on flowering in February-April - 11-12 ° C, while forcing to bloom in July and August - 1012 ° C.Two weeks later, several temperature increase: first and second cases - to 15 ° C by day and 18 ° C at night, in the third case iRis.atsvetut at any temperature.
