How to plant irises in the fall – step by step instructions

Features of the autumn landing

The amazing vitality of a flower Allows you to freely experiment with the timing of planting in the open ground, choosing the optimal time for good rooting and subsequent formation of flower stalks. The unpretentiousness of irises allowed them to grow in a wide range of climatic zones from Siberia to arid southern areas.

Many breeders have been bred with color from white to almost black, with a purple tint. Such a riot of colors only confirms the name of the flower, which from Greek translates as rainbow.

The perennial grows quietly in one place up to 5-6 years without transplantation and daily care.

If you need to change the location or planting an overgrown bush, then autumn or the last days of summer is usually chosen – during this period, flowering has already passed, the root buds are strong enough and division will not violate their structure.

Important: the activity of pests and pathogenic bacteria decreases in the fall, iris will more successfully take root and wake up earlier in the spring.

Optimal timing

Breeding work new, frost-resistant varieties allowed to plant irises in Siberia, the Urals and in the suburbs.

Preference is given to varieties:

  • White moth;
  • Ruby Morne;
  • Hang glider;
  • Queen’s show;
  • Hubbard.

Species of bearded iris are more capricious, but with the technology and timing of planting, they also grow successfully in open ground.

By region

For the northern regions, it is recommended to plant irises in early September. They will have time to take root and gain strength.

Autumn planting is preferable for bulbous varieties, and those that have rhizomes are best left in the spring.

For the southern regions, you can the plantings should be moved to the end of September or even mid-October.

If the irises are too early to plant, they will take this as a guide to action and the buds that fall asleep for the winter will wake up. remaining until the first frost.It should be in stock for about a month.

According to the lunar calendar

Every year new recommendations are made on planting and caring for different crops in accordance with the lunar cycles.

There are special rules for bulb, root and fruit trees.

  • The general condition is the ban on any planting on the days of the new moon, full moon, the day before and after them.
  • Landings are usually carried out on the growing moon, pruning and weeding on the waning.

Site preparation

Ирисам подойдет солнечный участок

Irisam is suitable for the sunny area

When choosing the best place for a flower bed, remember that irises cannot live without the sun. In shaded areas, they will not bloom or quickly degenerate into nondescript inflorescences.

But their moisture requirements are different and depend on the species. Swamp iris feels great in humid areas, but this is the exception to the rule.

These flowers tolerate a lack of moisture much more easily than its excess, so they are often planted on hillocks or artificial hills.

Correct planting guarantees lush flowering for 4-5 years, until the overgrowth of the bush.

General requirements for the site:

  • it is open and sunny, protected from the wind;
  • deep bedding of groundwater;
  • lack of close fruit tree neighborhoods;
  • greasy nutritious loams are desirable;
  • low or neutral soil acidity.

To prepare for planting, the soil is dug with compost or humus with the addition of wood ash. If the composition is poor, then potash and phosphorus fertilizers are required. It is better to leave nitrogen complexes in the spring.

In autumn, the plant should take root, and not grow.

Note: the root system of irises is very close to the surface, so the depth is calculated based on from the size of the bulb or rhizome. It should not exceed three times the height.

Planting Technology

Bearded and beardless varieties are very similar in planting and subsequent care technology – they are bred using roots or seeds.

In the second year, the root system already allows a single division.

It just requires it for 4-5 years, otherwise the planting thickens and the flowering quality deteriorates.

Dilution with roots

A well-grown healthy bush is selected for division. A month before the transplant, it is no longer fertilized, watering is reduced by 2 times.

To get planting material, you need to:

  • dig a bush around the perimeter;
  • gently pull it out without breaking small roots;
  • dry;
  • divide with a sharp knife into segments, in each of which there will be a plot of root of at least 10 cm, a fan of leaves, several sleeping buds;
  • cut the leaves into 13 lengths;
  • the places of cuts at the root should be treated with crushed charcoal;
  • as an option, disinfection with ashes or a solution of manganese is carried out;
  • if part of the rhizome without leaves is intended for planting, it is previously kept they are buried in the sun (2-3 days) to improve growth;
  • a mound is formed in the middle of the hole, raising the rhizome above the ground;
  • the bush sits on an elevation, the feeding roots straighten along its slopes;
  • neighboring plants are planted no closer than 15 cm, large varieties require a distance of 45-50 cm;
  • bulbous species bury no more than 12 cm.

It is worth considering: if you need a quick cultivation of the variety, you can use small fragments of the rhizome without leaves.

For good growth and abundant flowering, new bushes in slipped over, having rhizome in a southerly direction. This factor should be taken into account when planning the size of the flower garden.

A plant is planted correctly if the fan of leaves is standing strictly upright, the root part and the neck slightly protrude from the ground. After 2-3 weeks, the plant should be firmly rooted.

Growing from seeds

Rare varieties are grown from seeds

Sometimes you want to plant some special variety that neighbors and acquaintances do not have. Such plants are ordered online or bought in specialized stores. There they are sold mainly by seed. The process will last longer, flowering will have to wait 2-3 years.

From the seeds grow marsh, Siberian, varietal, Japanese species. The disadvantage is the possibility of pollination and violation of parental characteristics.

Externally, the seeds are large, brown. Ripen within 2-2.5 months in seed bolls after flowering.

Autumn sowing is preferable, because when storing seeds their germination rate decreases rapidly.

The term does not matter, the basic requirement is at least 3-4 weeks before the first frost.

  • Prepare ridges in advance at a distance of 20-35 cm.
  • Seeds are buried by 2 cm, covered with fallen leaves, mulch and double top a layer of geotextile.
  • The seedlings are transplanted to a permanent place in the spring, after heating the soil to +15 degrees.

Standard care in the summer consists of weekly watering, fertilizing 3 times per season and regular weeding.

Help: manure should not be used in any form.

Care for the seedlings and preparation for winter

After planting, the plants are left alone for 3-5 days, then plentiful watering through a watering can or divider is required, so as not to blur the earth from the roots. Then, to preserve moisture, the hole is sprinkled with dry sand. The main care consists in timely weeding.

Important: the weed will have to be manually so as not to damage the iris roots located close to the surface.

No additional fertilizer for winter is required. To preserve plants in the winter, recently transplanted bushes with the first frost are mulched with sawdust or spruce branches. In spring, the mulch layer is removed as early as possible, at the very beginning of the thaw season.


Usually, when the planting is successful and the rooting is successful, the bush blooms the next season. After a year, it can be propagated by dividing the rhizome. In rare cases, flowering is delayed, then you need to be patient. Apparently, a special variety was found that required more time for acclimatization.

Autumn plantings have a beneficial effect on irises, reducing the risk of developing fungal diseases of rhizomes and bulbs, save plant strength for an earlier start of growth and flowering.

In September or early October, it is worthwhile to devote several days to sowing seeds or transplanting overgrown bushes – and in spring to enjoy the rainbow color, plant new flower beds from the sprouted seedlings.
