Irises, like most garden flowers, need to be periodically transplanted. At one place a young bush can grow from three to five years, however, during this time it forms many new links that begin to simply bulge out of the ground. As a result, the flower is sick, and the flowering itself is noticeably depleted. Iris transplantation contributes to its rejuvenation, which increases the number of peduncles and improves the general condition of the plant. Moreover, in this way the plants multiply well, because they take root quickly and easily.
When to transplant?
Many flower growers begin to divide the bushes in the autumn or at the end of the summer, as soon as they bloom. Can Iris be planted in spring? Of course, it is possible, because spring is the time of rapid growth of all vegetation. Irises, planted in spring in moist soil, take root well.
The dates of spring transplantation depend on regional climatic conditions, but in any case, it should be done as soon as possible - as soon as the snow melts and the ground warms up a little. Postpone work is not worth it, because when late planting roots can get sick and die.
When spring transplanting irises should be borne in mind that plants are likely to bloom only next year. Although there are cases that bloom still comes this summer, but more later.
How to transplant irises in the spring?
To plant an adult bush of irises, you must:
- using a fork to carefully dig it up,
- cut with a sharp knife, each delenka should be about 10 cm long, several leaves and a well-developed own root system,
- in the presence of traces of decay, cut off the damaged parts of the roots and put the rest into the solution of manganese solution for two hours,
- if the roots are too long, it is better to cut them, leaving no more than 5 cm,
- leaves should also be cut to a height of 15 cm,
- sprinkle all the cuts with wood or activated charcoal and let them dry.
For planting separated irises, it is necessary to make shallow holes at a distance of at least 40 cm from each other, so that the plants will not be closely in the next few years. In each make a little saltpeter and superphosphate and mix them with the ground. In the center of the hole, build a mound of soil, place a division on it, and straighten the roots, directing them down. Cover with soil and it is good to rub it around the iris with your hands.
The iris rhizome must be flush with the surface of the soil; it cannot be dredged much.
When is it better to transplant irises?
The main recommendations for transplanting irises:
- do it regularly, at least once every 5 years,
It is possible to study transplanting in spring and autumn, but with the first option:
- root damage due to temperature fluctuations and the possibility of heavy precipitation is possible,
In the fall:
- possible damage to ungrafted roots as a result of the first frost (if you calculate the time for planting incorrectly),
- the ideal period is from early September to October
The main points to consider during the spring transplant are:
- dig the plant with extreme caution, since the roots during this period are the most fragile, there should be no damage,
- dig only with a lump of earth,
- can not be planted if the soil is frozen, otherwise the plant may not survive.
Stages of transplantation:
- A healthy and strong bush is dug.
- The rhizome is thoroughly cleaned from the ground.
- Removed rotten and damaged roots.
- The leaves are pruned.
The main recommendations for transplanting in the spring:
- water infrequently and a little bit
When choosing a suitable month for such an action, it is necessary to take into account that:
- Iris should bloom completely,
- the rhizome should have time to firmly settle in the soil, therefore, in the near future frost should not be expected,
- in November (for the northern and central regions earlier) cover the plant with a veil.
Stages transplanting in the fall:
- First you need to carefully loosen the ground,
- Add the required amount of minerals,
Closer to the onset of cold weather is required:
- slightly loosen the soil
- put humus
- make a top layer of sawdust.
Ways to transplant
There are several ways, each gardener determines the appropriate one, guided by the characteristics of the soil and the characteristics of the plant.
- Dig out the bush completely:
- With a shovel, the rhizome is removed from the ground. It’s important not to damage anything.
- leaves are pruned,
If undermining damage to the rhizome is found, then this plant is not suitable for partial transplantation.
Prevention of diseases during transplantation
So that there are no diseases, and the iris often rot the roots or leaves, preventive measures are necessary:
- Hom regularly loosen,
- remove weeds,
- water moderately, if the soil is excessively wet, it will quickly affect the general condition of the plant,
- if the roots are rotten, then you need to immediately dig out the iris, get rid of the rhizome from the rot and put into the “HOMA” solution for 20 minutes, then dry and plant again,
- it is not worthwhile to take a long pull with a transplant, lost time can have a negative impact on his health in the future or even lead to death,
- better to do all the work in the morning,
- plant irises should be no closer than 50 cm apart,
- strictly follow all the guidelines for disease prevention,
- do the treatment in a timely manner.
Why need a transplant of irises
Irises are unpretentious flowers, grow well even on depleted soils, undemanding to top dressing. However, the plant has one small drawback - the culture is rapidly "growing in breadth." That is, several years after planting a single tuber, the flowers may so overwhelm the flowerbed that they will not have enough nutrition for development. Transplant - the only way out.
When is it better to transplant irises in autumn or spring?
Irises are one of those flowers that take root quite quickly and easily, so you can start a culture transplant both in spring and in autumn. However, in the spring, the plants will delight in flowering, it is better to transplant early - when the threat of night frosts is over. In autumn, the procedure should be started no earlier than September in the central part of Russia, and not earlier than October - in the southern regions of the country.
How to transplant irises in the fall to a new place
When transplanting irises for the winter, it must be remembered that only bushes that have a well-developed root system and flower buds can be transplanted. In addition, the timing of the procedure should be chosen in such a way that the plants could take root and gain nutrients before the soil freezes (on average, the iris requires a month and a half).
As for the transplant itself, it is very simple:
- inspect the flowerbed, select those flowers that have well developed stems,
- carefully dig up the plants with a garden fork (or fork), shake off the ground, if necessary, wash the tubers under running water,
- divide the tubers into links so that each link has a fan of leaves,
- cut the roots of tubers to 5-7 centimeters, and the leaves - up to 20 centimeters,
- process the tubers with a weak solution of "potassium permanganate", dry them,
- prepare a seat for irises (dig a bed, check the acidity of the soil, if necessary, add a little ash or lime to the soil (the irises do not like acidic soils),
- make in the flowerbed grooves equal to the length of the roots of planting material,
- put some soil mixed with complex fertilizer for irises on the bottom of the dimples,
- place the tubers in the prepared holes (try to make the rhizomes flush with the main ground level), sprinkle them with earth, pour.
Do I need a transplant of irises
"Iris" can grow for a long time in one place. But over time, they cease to delight their bright, eye-catching colorful flowers.
This is due to the fact that the root system of irises has the ability to grow rapidly, placing new rhizomes on the surface of the earth in the form of a ring. For this reason, part of the old roots, which are usually in the center of the bush, dies, forming a "dead zone".
When new shoots lack space and nutrients, as a result, the plant starts to hurt and gradually dies.
To prevent this from happening, it is necessary to spread the irises in a timely manner in the spring, about once every 5 years. Flowers quickly adapt to a new place, root well on the condition of a properly performed transplanting procedure.
Beginning gardeners do not know when to replant irises, so as not to harm the plant. It is possible to rejuvenate iris bushes by planting both in spring and in autumn. Many gardeners prefer to do Kasatik transplant at the end of August and the beginning of September. The plant has faded, and you can begin to divide it into parts. But then you have to take into account the likelihood that flowers can freeze out before they take root. There is such a nuisance quite often, especially in the northern regions of our country, where the winters are quite severe.
To reduce the risk of loss of varietal irisesIt is not forbidden to engage in transplanting flower culture in the spring.
And here it is necessary to consider the following nuances:
- work on dividing and replanting flowers should be carried out in early spring, from mid-April to early May,
- Iris will bloom, having transferred a transplant in the spring, most likely to another year. But if you have time to ripen the kidney, you can admire the bright large flowers in the summer. This is especially true of bushes transplanted in the first decade of May, no later. Apparently, this is due to the onset of heat, since in April the soil is still not heated to the desired temperature.
Before you begin work on transplanting irises in the spring, you need to prepare new seats. No matter how unpretentious these flowers are not considered, but the observance of some rules during the reproduction and transfer of bushes to a new location will further guarantee the varietal qualities of the plant.
Seat for irises are prepared as follows:
- it is required to dig the soil thoroughly, remove all weeds,
- to make a complex of mineral fertilizers, so that the plant could take root faster and get all the necessary nutrients for full growth and flowering in the future,
- with organic dressing you have to be extremely careful. This is due to the fact that the use of organic matter stimulates the growth of leaves to the detriment of flowering, and also often provokes the development of fungal diseases leading to the death of the plant,
- “killers” grow better and bloom together in areas where there is enough sun and little chance of strong winds. It is necessary to pay attention to this when a place is chosen for a future flower bed.
Iris Transplant Rules
Preparing a seat, you can begin the main work on the reproduction of the flower bush.
How to transplant irises:
- a plant is dug necessarily with a lump of earth, such a reception ensures minimal damage to the root system,
- carefully clean the roots of the flower culture from the soil, because at this time of year the iris roots are very thin and fragile,
- carefully inspect and, if necessary, remove all rotten, damaged places with a sharp garden knife,
- if last year's foliage is present, it is also carefully cut with a knife,
- the root of the plant is divided into smaller units, or as they are also called delenki or fans. The optimal size of the deal is 3-5 cm,
- it is necessary to disinfect the roots in special solutions, for example, potassium solution, for at least 20 minutes,
- after which they carefully dry and treat the cut sites with charcoal powder,
- make a small depression in the prepared hole and plant the iris, trying not to bury the roots of the plant especially deeply. Otherwise, the flower will die, not even rooted, as the probability of rotting of the roots is very high,
- after planting the iris outlet, moderate watering is necessary,
- have iris bushes at least half a meter apart.
Prevention against pests and diseases of irises
One of the main enemies of this flower culture is gladiolus trips.
The result of the appearance of a harmful insect is the loss of wax on the leaves of the plant, they begin to fade.
The drug “Confidor” will get rid of this misfortune - 1 ml is diluted with 10 liters of water, after which the infected plants are treated with a sprayer.
Irises are quite sensitive to an excess of moisture, so often their root system affects rot. You can save the plant only with drastic measures: dig up, remove all affected links, treat with a disinfecting agent, then dry thoroughly and, after all measures, plant on a new, drier part of the garden.
At the end of summer, small brown specks can be seen on the leaves of irises. They signal that the flower is affected by heterosporosis, a fungal disease. Control measures include the removal of infected leaves and the treatment with copper sulfate solution prepared at the rate of 50 g per 5 l of water.
Charming, with a pleasant unobtrusive aroma of irises are able to decorate any garden, without requiring laborious efforts to care for their plantings.
Iris transplant in autumn
September is the best time to transfer irises to a new site. They quickly take root in the open field, winter well and, when spring comes, they are ready for flowering.
Transplantation is carried out in compliance with these rules:
- only shrubs with a sufficiently developed root system need relocation,
- choose those shoulder blades that managed to separate from the mother bush and give good roots before the onset of cold weather,
- be sure to pay attention to the flower buds have already been fully formed.
On a note! Despite the frost resistance, the irises planted on the new site are covered with spruce branches or fallen leaves. This will provide better rooting and protect against frost.
How to transplant irises
Each gardener makes a transplant of irises when it’s best for him. In any case, you need to follow certain rules:
- on the bushes selected for transplanting, leaves are cut in half the length, cut at an angle,
Note! If brown spots are found, it is better to cut the leaves completely and destroy them, and treat the rhizomes with a solution of copper sulphate (10 g of the drug per bucket of water) and separate them from other flowers.
- rhizomes are dug and cleaned from the soil, too dirty washed with water,
- rotted parts and dry foliage are removed, in this case the rhizomes are kept in the “Khom” solution for 20 minutes and dried for 12 hours,
- when they divide the bush into parts, they see that there are 2-3 knots with sleeping buds on each delenka,
- cut the rhizomes only with a sharp knife
- cutting sites are treated with wood ash or gray mixed with activated carbon,
How to transplant irises
- remove unnecessary roots,
- the cuttings are kept in a weak solution of potassium permanganate,
- planting material is dried on the bed, turning periodically to the sun's rays touched each part of the layer.
Important! Only young roots are taken into the transplant, old ones without regret can be thrown away. If the plant is fed, then digging is done not earlier than 2 weeks after fertilization.
The main methods of transplantation
- Full digging of the bush - the whole plant is removed from the ground, the roots are shortened to 3 cm, the leaves are cut to 10 cm, then the bush is cured for 2 days and also completely dropped in a new place (if the plant is not more than 4 years old) ) or dismember delenki (old bushes),
- Partial - a tunnel is made under the bush, the necessary number of cuttings are cut off, which are placed on new places.
Note! If in the second variant the rhizomes were damaged, then it is not recommended to use the hive for partial transplantation. It is better then to dig it up completely and revise the layers.
The new site where the planting will take place should be sunny - the iris do not like constant shadowing. Be sure to take into account the location of groundwater - they should not be above one and a half meters.
- If the layering has a different size, then under the length of each spine a hole is dug,
- A layer of earth mixed with fertilizers (potash or phosphate) is placed on the bottom of the depression,
- A small mound is formed,
- The root is set on a hill, slightly pressed into it,
- Sprinkled with soil in such a way that the kidneys remain under a 2-centimeter layer of soil,
- Fresh landing plentifully watered, if necessary for a while, a small shadow is created.
Placing iris blades in a flower bed, trying to maintain the vertical position of the leaves, focusing on the north. Then the roots will always be heated by the rays of the sun.
On a note! Root for planting choose a diameter of 20-30 mm, with a length of not more than 60 mm. Then in one seat can be set up to 5 blades. The distance between the holes is kept 0.7 m (with separate landing options - 0.5 m).
Секция касатиков – лимиирисы
Описанная технология подходит для бородатых касатиков. If on the site grow representatives of the bezborodnik group, limiiris (Siberian, smooth, bristly, water), then here are taken into account when transplanting such features:
- layings after digging are not dried, the plant is transferred with a clod of earth,
- the wells do deeper than ordinary irises,
- create shading in hot weather,
- Abundantly watered throughout the season.
This kind of killer whales are more often planted in the spring, although planting material is collected in the fall and kept wrapped in moss.
Interesting. Limirises are more capricious than the “bearded”, but outwardly no less beautiful. Abundant flowering, but without the usual aroma.
Iris transplant in the suburbs and Siberia
The iris is rooted so quickly that a month is not so important for their planting. The main thing is to pay attention to climatic features, as well as to choose drained soils with the presence of clay, ignoring sandstones.
In the Moscow region, in the Urals, in Siberia, they are not particularly wondering when the irises can be transplanted from one place to another. For flower growers in these regions, each warm month is good for working in a flower bed.
It is better to cook a new bed in the fall, digging and adding compost, humus, a little lime and bone meal. The bush can also be prepared from September. To do this, it is enough to cut off the new blades from the old rhizome and leave it in place until spring.
Additional Information. If in the southern regions the landings are started at the end of March, then for the middle zone of Russia you should focus on the second half of April - the beginning of May. Those who have been involved in irises for a long time have already noticed that the bloom in May is beginning to bloom earlier than in April.
As soon as the soil warms up to the desired temperature, the young bushes dig in and transfer to a new place of residence. In case of return frosts, it is better to sprinkle fresh plantings immediately with sawdust to prevent the roots from being damaged due to temperature changes.
Important! When spring planting, it is recommended to plant several delenok in one hole, forming your mound under each branch. At the same time, the pit, with a diameter of 0.4 m, is deepened to 15 cm. Gardeners engaged in flower transplantation in the spring of 2018, admired their iris already this year.
Those who decide to start breeding irises in the summer should start the procedure in the second half of July or in August, when the flowers on the bush wither. The rules for site preparation, planting material and the algorithm of work do not differ from those described above, but there are small nuances:
- A new section intended for transplantation is watered abundantly a few days before the main works,
- the soil at a depth of 20 cm loosened and add nitrophoska (80-90 g / sq.),
- roots dig into small pits just below the ground level,
- the direction of the leaf fan is southern, it will allow the plant to develop symmetrically,
- falling asleep hole, part of the scapula is left looking out of the ground,
- water is planted with warm water, so as not to injure the plants with temperature differences.
On a note! The transplanted irises will no longer bloom this year, but they have enough time to take root and prepare thoroughly for the winter period.
Landing in the fall
In the cooler regions, autumn plantings are also practiced, the most suitable period for this is the first half of September. Repotted killers need at least 2 weeks to have time to take root before the frost, which in Central Russia begins in October.
If the iris is transplanted in the autumn, the soil is dug up, but not fertilized - a complex top dressing is applied under the rhizomes in early spring. When powdering the roots in the hole, a small “back” is left to look out on the surface.
Important! If the rhizomes are completely buried, without giving the opportunity to "sunbathe" in the sun, the plant will quickly rot. This is an important point, no matter what season is chosen for transfers.
When several blades are planted in one pit, it is better to place them around the perimeter of the circle. So young plants will be easier to winter. New plantings in October are sprinkled with leaves, and if winter is expected to have little snow, then in November they will be covered with spruce branches.
If the cold comes earlier than foreseen, the bush can be divided into layers and, before spring, plant them in a greenhouse with light nutrient soil. Either root in flower pots with a substrate and land on a permanent place when spring frosts pass.
Having decided on the time of flower relocation, having studied the information on how to transplant irises correctly, even a novice gardener will easily cope with this work and very soon begin to enjoy the beauty of his multi-colored flower bed.
Why and after how much you need to transplant to another place
In order for the bushes to grow and bloom well, they need to create a comfortable environment. To transplant flowers to a new place, you need to choose a site on which there is a lot of sun, you must have good ventilation. Under these conditions, irises feel best and bloom profusely.
Planned transplantation should be carried out at least every three or four years. The best time for a flower to master the new soil is spring, when the active phase of leaf growth begins. But you can make a transplant in the fall.
When to plant irises in the fall
The best time to change the place of residence will be the period after flowering or vegetation. If transplanted irises in the process of flowering or too late after it, then they probably will not tolerate transplants.
It is worth choosing the time at the beginning of autumn - it is best to get down to business in September, while it is still warm. But in late autumn, after mid-October, transplantation is not recommended - the iris may not settle down and fade.
Transplantation in the fall has several advantages: at this time, the rhizomes are not forced out, which means it does not reduce the duration and abundance of flowering. Also during this period, the bush grows well, you can sit after that or leave to bloom and get a large number of flowers.
Choosing a place on the site
When choosing a site, it should be remembered that these flowers are light-loving, therefore it is recommended to select a site with good access of light and wind, preferably without shadows and excess moisture. If there is too much water in the soil, it can lead to root rot or mold and other diseases. Therefore, you need to monitor the groundwater level at the new location.
It is not recommended to plant the bush in heavy and sour soil. The best option is to place a young plant in a loamy soil with a neutral reaction.
The lighting should be bright enough, the bushes also like ventilated places, but not with strong wind. It should be remembered that the site for planting must be prepared in advance, digging the soil.
Place under the flower should dig in advance, at least a week or two. Ideally, such training is carried out even a few weeks before the planned movement of irises. They dig a hole about twenty centimeters deep, that is, in a bayonet of a shovel.
If necessary, sand with peat is applied to the soil. If the soil is too sour, be sure to add at least a handful of lime.
It is important to conduct and fertilizing the land: for this suitable mineral fertilizers, to which the bushes respond well. If you fed iris with one type of fertilizer, then use them.
If the bushes are already old and very large, it is better to dig them out using forks, slightly planting roots on them. Damage to this case is indispensable, since the roots of the plant are very fragile.
Therefore, if the volume is quite large, you will have to separate them and transplant only some of them. After the main part of the roots that will be transplanted is selected, they can be washed with water.
This will allow you to view the status of the system and determine whether to use these particular controls. Sick, dry and damaged parts are removed.
For transplantation in the fall, you need to choose potash and phosphate fertilizers - nitrogen at this time is not suitable.
Organic matter is very poorly tolerated by plants, it is better to add ashes to the hole, about a handful or two, and after that, plant the iris in a new place.
How to plant irises in a new place
At the new place, it is necessary to create conditions for free growth of each bush. So, the land has already been prepared and loosened, it contains fertilizers.
Plants are placed in pits with a depth and width of about 20 centimeters, gently sprinkling with earth to form a small hill.
Tips to help in planting irises in the fall:
- Do not place the plants too deep, otherwise they will start to rot. The top of the root system should be at ground level.
- Rhizome when planting need to straighten in different directions.
- Choose 3-4 rhizomes for planting.
- All sections must be treated with an antiseptic.
- Choose a dry rather than a rainy day for planting.
- It is not necessary to apply fertilizer directly when planting a plant - there are enough of those that were introduced before preparing the soil.
The distance between the holes should be at least 50 centimeters - this will ensure the free growth of bushes in the future.
It is rarely necessary to water the plants after transplantation, as the cold period is approaching, besides, an excess of moisture will prevent the shrub from taking root. Fertilize also should not be.
After transplantation, dry leaves may appear, but this is quite normal, as the flower only gets used to a new place: fresh brand new leaves will soon grow.
Preparing for wintering plants at this stage ends. Since they are winter-hardy, cover and insulate them to anything, the necessary trimming has already been done. Special care after such a transplant is not necessary.
Irises are very beautiful flowers, easy to care for and maintain. The process of transplanting them is quite simple. The main thing is to choose the right place and its preparation. If you carry out this process as expected, then the bush will grow well even in the fall and have enough strength to calmly winter and very soon please you with beautiful flowers.
Iris transplant, why it is needed
The root system of irises grows in breadth, captures all new territories, suppresses neighboring plantings. In addition, powerful roots eventually age and begin to rot. This can lead to the death of the plant.
The transplanted and renewed plant begins to grow rapidly, new young shoots appear, active flowering is observed. When transplanting, the soil is replaced, which during the growth of a powerful bush is depleted, damaged by diseases and pests.
The most favorable time for transplant
Transplantation of irises can be done at any time, if they do not bloom, and you are not going to share them. But they do it in emergency cases, for example, you did not have time to transplant it on time, and the bush has grown so much that it interferes with neighboring plants.
But it is still better if you do it on time. Experienced growers consider spring and autumn the best time for dividing and transplanting. Moreover, some of them prefer the autumn transplant. It is believed that it is more benign.
Nuances of autumn, spring transplant of irises
Transplantation can be carried out in the spring, when the soil is already warm, the flowers began to grow. For the middle band this may be the end of April - the first decade of May. It is necessary to be afraid of a break of roots as at this time they are very fragile.
According to other gardeners, the best time for this procedure is early autumn (from early September). The plant by this time has faded and will grow a green mass of shoots. If the transplant is done on time, by the cold the saplings will take root and bloom abundantly next summer.
We will get acquainted with each method of transplant in more detail.
Preparation of planting material
It is better to dig a bush with a pitchfork in order not to cut the roots, to shake off the ground from them. The rhizome is carefully inspected, cut rotten and old parts. Cut the leaves to a height of 10 cm. Sections can be covered with brilliant green, crushed coal or other antiseptic.
We cut the side roots up to 3 cm. If the plant is going to be divided, then we cut the rhizome into several parts, leaving 1-3 bunches of leaves on each. Delenki stand in the solution of potassium permanganate. You can use other tools offered by specialty stores. After disinfection of the rhizome, dry and plant.
- In the prepared garden we make holes at a distance of 1.5 m. If you divide the bush into small sections, the distance between them can be 40 cm.
- In the hole we pour a mound consisting of a mixture of fertile soil, sand and a teaspoon of complex fertilizer.
- At the top of the hillock we place the delenka, and we distribute the side roots along its slopes.
- Sprinkle the rhizome of the iris on top of the ground, press it lightly and pour water with Phytosporin. No more watering is required.
- In November, with the onset of the first frost, planting harbor a layer of peat or lapnik. In the spring, when the snow melts and the soil begins to warm up, the shelter is removed, the peat is otgrebayut.
Care for autumn planting irises
If autumn was dry and warm, seedlings should be watered three or four days after planting. The soil around is gently loosened so as not to damage the surface rhizomes. Further care depends on the ambient temperature.
When approaching cold landings cover mulch from peat, dry grass and leaves, spruce branches. This will save young plants from freezing. This procedure should be mandatory when growing irises in Siberia. In spring, when the snow melts and warm weather sets in, the shelter needs to be removed so that the spring sun warms the earth and the roots of the seedlings.
Autumn plantings bloom as early as next spring. Abundant iris bloom begins in two years.
How to care for irises planted in the spring
Planted in the spring of plants, above all, should be protected from the bright spring sun. Landings are mulched with dry grass or soil. With insufficient moisture, the seedlings are watered.
Since in spring, adult bushes with powerful rhizomes are transplanted, they take root well and with the onset of autumn can do without shelter. It is enough to sprinkle the protruding roots with earth.
