Planting bearded irises. Iris planting and care in the open field top dressing reproduction

Bearded irises are lovers of heat and bright sun. These beautiful flowers, according to legend, grew on the site of a rainbow that broke out all over the earth when Prometheus gave fire to people. This bright flower has 700 various kinds and countless shapes and shades. The most spectacular of them is the bearded iris, a tall and beautiful flower.

Time and place of planting bearded iris

The best time to plant an iris is during the active growth phase of its root system, which begins immediately after the flowering period. At different types iris, this period will be different, but it is the bearded iris that blooms in July - at the beginning of the month it begins to bloom, and ends by August. After the iris has faded, you need to wait a couple of weeks, and then you can start dividing the bushes for planting. It turns out that this is the very end of July and the beginning of August, but landing is possible until the end of summer. In the southern regions, where heat lasts longer, planting is possible until the end of September. It is impossible to delay planting for a long time - the flower will not have time to take root before the onset of cold weather.

As for the choice of location, it should be a sunny area without shading. Shading is allowed only partial in the afternoon - the iris loves the sun very much, and in the shade it does not bloom well. Protect your landing from gusty winds - this delicate flower just fly around.

When choosing a soil for planting, it is better to focus on slightly acidic or alkaline soil. If there is no suitable one on the site, then the existing one can be improved. Add sand and peat to heavy soil, and lime to acid soil. For bearded irises (unlike other species of this plant), rocky soil is also suitable. It is also important to monitor the absence of weeds - they can cause flower diseases.

Planting bearded iris

When the site is selected, you can start landing. sit down bearded irises rhizome, not seeds, because seed propagation does not preserve the properties of the variety. In a small hole, a mound is poured in the center, on which the rhizome is located, and the roots are distributed along the edges of the hole. The roots are sprinkled with soil, and the mound with the rhizome is covered with a small layer of coarse sand. You can not deepen the rhizome, otherwise the plant will not have enough strength to hatch up. Holes should be made at a distance of 50 centimeters. Watering immediately after planting is not required.

Iris bearded care

Caring for this flower is not too difficult, the basic rules are to fertilize and remove weeds. As noted above, weeds create conditions in which diseases dangerous to iris develop well. Therefore, their prevention will be frequent weeding.

As for feeding, it is better to do it with mineral fertilizers three times a year:

in early May at the time of bud growth;
at the beginning of June for better development peduncle;
a couple of weeks after the start of flowering to form buds for the next flowering.

During these periods, you can sprinkle the soil with a small amount of ash, which will reduce the acidity of the soil and reduce the risk of flower diseases. It is better to cover imported varieties for the winter in order to avoid freezing of flower buds. In this case, the iris will continue to grow, but will stop blooming. Russian breeding varieties can not be covered - they will survive the frost perfectly. Irises are covered with soil or peat, and in the spring they carefully remove the shelter. If the rhizomes are frozen, they will become soft and white. This plaque must be scraped off to a hard tissue, smeared with brilliant green and sprinkled with ash.

Diseases and pests

The most common disease of bearded irises is bacteriosis. It arises due to the deep planting of the rhizome, when he still managed to break through the soil layer. In this case, soft rhizomes can be observed that have become Brown. They just start to rot. In order to save the flower, you need to dig it out, remove all rotten tissues and disinfect the rhizome with potassium permanganate. After that, the plant must be placed in the sun and allowed to dry, periodically turning it. The causative agents of the infection will soon die from the bright sun, after which the iris can be planted back, but already correctly.

In the dew season, that is, from the second half of July until the end of summer, bearded irises are prone to rust. To save the plant, treat with preparations containing copper. Also, bugs can start on irises that infect the leaves. To combat them, drugs against the Colorado potato beetle are perfect.

The use of bearded iris in landscape design

Stronger perennial flowers and plants can inhibit the growth and flowering of irises, so they are planted in groups. Moreover, mixed landings can adversely affect soil moisture, and irises do not like excess moisture. To the company of these high beautiful flowers suitable poppies, gladioli and phlox. You can also play with different varieties of bearded iris in one flower bed - it can combine one-color and two-tone flowers, as well as bordered and iridescent. Their diversity will provide elegant flowering in the garden.

winter hardiness different varieties bearded irises is different, so it is more reliable to grow varieties that winter well in this region. Bearded irises are propagated vegetatively by dividing the rhizomes of 3-5 year old plants. Bearded irises are planted in the summer - from mid-August, and at the very beginning of autumn, so that the plants have time to take root before the cold weather, but if necessary, you can plant irises in the spring. The August-September division of iris rhizomes gives a large percentage of plants that bloom in the first year after planting. Transplanting irises in your garden "from ground to ground" can be started 2 weeks after the end of flowering and carried out at a convenient time.

In one place, without prejudice to the decorative effect, bearded irises are usually grown for no more than 5 years, then the bushes are dug up with a pitchfork and cut into planting divisions. A delenka is a part of a healthy rhizome with roots, usually an annual link with a blade of leaves, but a small piece of rhizome with dormant buds can also be used to propagate valuable varieties. A piece of iris rhizome weighing only half a gram with one dormant bud is capable, under favorable conditions, of giving life to a new plant that will bloom in the second year of vegetation! The rhizomes of irises without roots and leaves remaining after cutting the divisions are cut off, removing the damaged parts, powder the cuts with crushed charcoal, dry them and plant them on a separate bed for growing next season.

The rhizomes of the delenok are disinfected for 1-2 hours in a beet-colored potassium permanganate solution, dried and heated in the sun for 3-5 hours. The leaves and roots of the division, if their length is more than 10 cm, are shortened. Bearded irises prefer well-drained, light soil without stagnant moisture, soil in the sun, but they also tolerate a little shading (some flower growers successfully grow them under apple trees with a sparse crown). Too acidic soil is sprinkled with wood ash before planting irises. If there is a danger of stagnation of melt water in the spring, before planting for irises, a flower bed is slightly raised above ground level. The distance between plants when planting irises depends on the purpose of planting and the height of the irises: undersized irises are usually planted after 15 cm, medium-sized - after 20 cm, tall - after 40 cm. In free landscape compositions, irises are planted in groups of several pieces, placing divisions around the circumference; the distance between groups is not less than 1 m.

Some flower growers grow a collection of irises on a raised bed according to a 30x50 cm scheme, turning the leaves of irises when planting in one direction and directing the plane of the leaves across the ridges. Before planting irises, the soil should be dug up on a shovel bayonet, a bucket of compost or well-rotted manure per 1 sq.m. (fresh manure is not used to avoid rotting of rhizomes), make planting holes, but fill the bottom of which with a mound of earth. The rhizome of the divider is laid on a mound so that after planting it protrudes half above the soil level, the roots are straightened on the sides of the mound and the hole is covered with earth, carefully compacting it with hands. Deepening the rhizome into the soil can lead to the death of the iris.

The rhizome of the iris can be fixed from falling and for quick rooting with wire arches or wooden spears. After planting irises, the earth is abundantly watered with water, after it dries up, repeated watering is desirable after a few days. Further care for planting irises consists in manual weeding (so as not to damage the roots of irises located near the surface of the soil), shallow loosening of the soil. New plantings of irises need shelter in late autumn from freezing: hilling with earth or falling asleep with a leaf, straw, needles, tops with a layer up to 10 cm; shelter is removed in early spring.

There is a special anti-vandal property - they do not want to be torn off! When the question arises of what flowers to plant near the house or entrance, subconsciously they often choose irises (they are cockerels, or irises). A huge number of different shades determined their name: irises are named after the goddess of the rainbow.

They bloom in spring, and some varieties bloom again in autumn. These perennials bloom especially luxuriantly in the 3rd year after planting. Rhizome irises are extremely unpretentious and are not afraid of winter. Here is the former wild flower urban.

Maybe for someone it will turn out to be a discovery, but under the common name "iris" in fact, very similar in appearance, but different plants are hidden: rhizomatous and bulbous iris. The latter, in turn, includes three genera:, and juno. Each of them has its own characteristics.

Planting irises

Rhizome irises photophilous. But they can also bloom under a tree, especially in the southern regions. Most of all, they do not like excesses: excess and waterlogging of the soil can destroy them.

If you have a choice, get large rhizomes - they have more stock nutrients. If a delenka with 7 or more leaves, the iris will bloom the next year, in the spring.

Optimal landing time bearded irises - late summer, August. But in practice, rhizomatous irises are divided and transplanted either during flowering, or immediately after its completion (within a month).

With all the unpretentiousness of irises do not plant them in heavy soil. Add sand and peat, shovel this mixture well. Fertilizers with a minimum nitrogen content can be applied to depleted land. On the acidic soil irises rapidly grow leaves, but do not bloom or bloom weakly. In this case, the soil is ash or chalk.

If ground water close, consider soil drainage. Then you will avoid the most unpleasant disease for irises - root rot.

The earth is dug up on the bayonet of a shovel. Fertilizers (if necessary) are applied a week before planting. It should be planted shallowly so that the bud is at surface level (the upper part of the rhizome cannot be covered with earth), the leaves should be arranged vertically. Leave about 40 cm between plants for further growth. Water immediately after planting. The next watering is not earlier than in 3 days.

Sometimes, for some reason, you need to save the planting material for 2 weeks. You can not keep the rhizomes in plastic bags and in a damp cloth. Store them in a cool dry place be sure to have good ventilation.

bulbous irises love the sun, moisture and well-heated fertile loose soil. The most undemanding to watering is juno, she loves dry places. Sunny rocky slides - the best place for her.

Landing dates: v middle lane- in mid-September, in the south - in mid-October. For the winter it is better to cover the plantings. In the spring, they will grow very early, sometimes even the snow will not have time to melt. Planting depth - 2 bulb heights, but not less than 5 cm.

After flowering (May-June) for a month, when the leaves dry up somewhere in half, the bulbs need to be dug up. The main thing is not to miss the moment: if they are flooded with rain, the risk of defeat will increase. fungal diseases. The dug out bulbs are washed in a 0.2% solution of potassium permanganate or another, dried quickly and stored in a dry, ventilated area until planting.

Per rhizomatous irises care is minimal. At first, weeds are pulled out by hand, as root system flowers is located at the very surface of the soil. It is also necessary to loosen carefully. When the bearded irises grow, weeding and loosening will not be needed.

Bulbous kinds require more care. autumn yellow leaves and with brown spots must be removed. In exotic species, the leaves are cut to half the length. At the end of autumn, heat-loving varieties cover. In early spring Hurry up and take off the cover.

Withered flowers are always removed by cutting the peduncle as close to the rhizome as possible.

Watering

In dry summer blooming irises watered in the evening making sure that water does not get on the flowers.

In windy places, tall irises are tied up: flower stalks can break under the weight of flowers.

top dressing

It is advisable to feed both rhizomatous and bulbous irises three times:

spring;
during the formation of buds;
rhizome - in August, bulbous - within a month after flowering.

Protection from pests and diseases

You can spray irises from pests once every 2 weeks (if necessary). Treatments are most effective 6 weeks before flowering. Usually this is not necessary, pests are not the main enemy of irises.

If rot has appeared on the rhizomes, it must be cleaned to a healthy tissue, then treated with a special solution. Then the rhizome is dried all day in the open air, occasionally turning over. The soil from the place where the iris grew is removed.

Familiar to all cockerels - bearded irises.

At bulbous Xifiums smaller size flower, but there are also plenty of varieties. Chic broad-leaved Dutch varieties are especially beautiful:

"Blue Champion";
"ideal";
Symphony.

And narrow-leaved:

"Seafire Beauty";
"Yellow Queen".

Some varieties iridodictyuma boast a delicate pattern on the petals.

At the flowers Juno the flowers are rather narrow petals.

Your flowers will be healthy if you love them. Good season!

The rhizome of this flower is called "violet root", and its aroma really resembles the faint smell of violets. In this article, we will talk about existing types and varieties of irises. You will learn how to properly plant a crop and how to care for it so that it grows in open field was successful.

Iris ( Russian name flower - killer whale) - a rhizomatous perennial with xiphoid leaves with a wax coating and thin, fibrous roots.

Irises can be found on many summer cottages. However, not all flower growers know how many varieties of these flowers are bred by breeders.

Multi-colored iris flowers (petal color - from white to dark purple), outwardly similar to orchids, have a pleasant faint aroma. Some varieties garden irises have a "beard" on the lower petals. The flowering of irises begins in May and lasts until June: each individual flower retains its decorative effect for about a week. The seeds of the plant ripen in autumn, in trihedral boxes that contain from 25 to 45 seeds.

Modern types and varieties of irises are so diverse, beautiful and fragrant that it is difficult to make a choice when growing in open ground in favor of any one variety.

Varieties and varieties of iris

There are the main varieties of irises, which are grown in summer cottages, in the open field in parks and squares, are used when arranging compositions in landscape design.

bearded iris

bearded iris(I. barbata) - this species is divided in turn into three subspecies, depending on the height of the plant:

undersized - plant height does not exceed 40 cm;
medium-sized - plants reach a height of up to 70 cm;
tall - above 70 cm.

The species got its name for the decorative "beard" that adorns the lower petals of the flower along the middle part. The color of bearded iris flowers varies from pale blue to dark purple. Breeders have bred a huge number of new varieties of bearded iris, including two-color ones with bordered petals. These varieties are very decorative, compact, with large flowers and an exciting aroma.

Russian iris

Russian iris(I. ruthenia Ker-Gawler) - forms low dense "pillows" - clumps. Varieties of Russian iris bloom with medium-sized flowers of pale colors. It tolerates short-term drying of the soil. In landscape design, it is used to decorate rocky hills and rock gardens, where rare watering is required.

Siberian iris

Siberian iris, which is actually called iris, is a tall plant, reaches 1 m. The flowers are saturated, purple with shades of blue. Siberian iris and its hybrids bred by breeders are distinguished into a separate subspecies of irises: limniris. In plants of this subgroup, there is no “beard” on the limb of the petals.

Iris marsh

Iris marsh, or yellow, grows in nature along the shores of lakes, rivers, along the slopes of wet ravines. It can develop and bloom well on saline soils, at high outdoor temperatures. These varieties of iris are successfully used in landscape design for decoration. artificial reservoirs: outdoor pools, ponds, waterfalls, iris tolerates excessive watering, looks great when planted decoratively.

Iris smooth

Iris smooth(I. laevigata Fisch) - cultivation at high humidity air; abundant watering is required. Planted near water bodies.

Germanic iris

Germanic iris- with sword-like leaves and flowers on tall strong peduncles, up to 90 cm long. The plant is suitable for decorating bouquets, grown for cutting.

Iris dwarf

Iris dwarf- a low plant, in total reaches a size of 10 cm. Forms dense curtains when grown in open ground. Small flowers have a variety of colors.

Iris Kaempfer

Iris Kaempfer(another name is xiphoid iris) refers to late varieties species irises. Leaves 30-40 cm high frame the flat flowers of the xiphoid iris. Peduncles reach 60-70 cm.

Japanese iris

Japanese iris- an extensive type of irises, which is divided into subgroups depending on the size of the flower. The cultivation of these varieties is most preferable due to the high decorativeness of the flowers. Japanese irises often form double flowers in different dates(early, middle, late, very late). The flowers of the Japanese iris are painted in all shades of rich purple. Flowers of this subgroup do not tolerate wintering well.

Planting a plant

Irises - planting and caring for plants of all botanical species in the open field is approximately the same.

Foreign breeders have bred varieties of tuberous irises, the cultivation of which is not difficult. These flowers have a small height and narrow, graceful petals of bright, saturated colors. planting material enters the sale in the fall, planting is done before winter.

To plant the bulbs, a trench is dug, the excavated soil is mixed with:

sand;
double superforsate;
crushed coal;
fresh garden soil.

Leave enough space between plants when planting

In the prepared grooves, the bottom of which is sprinkled with sand (you can spill it with a pink solution of potassium permanganate, epin or heteroauxin), the bulbs of irises are laid out with a sprout up.

Important! Bulbs should not be buried deep into the ground. Rule: it is customary to plant small-bulbous plants at a depth of 3 bulb heights.

Planting small-bulb irises does not require watering, the moisture that was used to irrigate the planting furrow is sufficient. The soil on top needs to be lightly tamped so that the birds cannot pull out the bulbs before they take root. Flowering of small-bulb irises will begin next spring.

Growing. bearded irises

Planting bearded irises requires compliance with certain rules:

Do not forget that bearded irises need to be fed very carefully.

It is impossible to bring fresh manure, compost or nitrogen fertilizers into the garden when planting.
In acidic soil, chalk or lime should be added first. The acidity of the soil should be reduced.
It is not allowed to plant rhizomes of irises in dense, caked soil. Preliminary digging of the soil on a spade bayonet and the introduction of sand will make the soil more acceptable for growing your irises in the open field.
The rhizomes of bearded irises are not buried in the soil: the buds should be at the level of the top layer of soil.

Proper Care

Iris in landscape design

Very often, iris is used when planting in parks, squares, when decorating territories in landscape design. A huge variety of varieties and species, as well as the high resistance of the plant itself, allow the wider use of this crop for landscaping. Curtains of irises of different varieties look great on a lawn carpet.

"Fields" of irises of different colors look very beautiful

Mono-plantings of iris culture decorate urban areas and do not require serious care. This culture has the advantage - perennial plantings in one place and maintaining a decorative look.

Varieties of irises: photo

Iris (Iris, Petushki) - perennial from the genus rhizomatous. Irises can be found in almost every garden, garden and park. There are more than 700 species, which are characterized by a variety of shapes and colors.

For this reason, the people called this flower rainbow. It is said that since ancient times the iris was named after the goddess of the rainbow, Irida. Outwardly, iris flowers are very similar to orchids and have the same rich range of shades.

Varieties and types

Gained wide popularity due to the presence of shaggy hairs on the petals. This type of iris is different sizes(dwarf, tall, canteen and others).

An important point when growing is that you need to plant this type of iris on the sand. To do this, sand is poured into the bottom of the prepared hole (in a small layer) and then laid out, carefully distributing the rhizome. Landing should not be deep.

It grows up to 80 cm high, while having flowers up to 10 cm, of various colors. The natural color of this species has many shades from blue to dark purple.

And as for some hybrid varieties, there are:

white ( Snow Queen ),

pink ( Imperial Opal ),

yellow with white trim Battz & Suga ).

With all this diversity, there is a significant minus of this type - there is no aroma at all.

(another name xiphoid ) has large flowers (about 25 cm in diameter), which are most similar to orchid flowers.

- one of large species(about one meter in height), drought- and frost-resistant. The flowers are lacy, have a bright yellow center and a white (dark purple, blue-violet and others) border.

A clear difference from other species is the fact that this iris grows only in moist soil. For this reason, most often it is used to decorate ponds.

- reaches only 15 cm in height, has wide leaves and yellow or purple flowers.

(xyphyllum ) – hybrid variety, first bred in Holland. They grow to a height of no more than 50-60 cm. The flowers have different shades of petals: white, yellow, orange, blue and purple.

It is winter-hardy, but in severe winters it requires additional shelter. Often this type of iris is used for cutting, forming bouquets.

- very interesting flower, which in Latin "spuria" means "false". It got its name for its resemblance to Dutch irises.

The main advantage is that the flowering period is longer (several weeks). The period of "life" of one flower is a week.

Iris planting and care in the open field

Irises are light-loving plants, so the key to long and colorful flowering is the location in a well-lit area.

During planting, it is worth considering the fact that irises are able to move. So in one year they can move a few centimeters away from their original location. Therefore, planting is not carried out in a standard way (in a row), but with a fan of leaves along a row. Planting conditions for each species are different.

So, for example, planting bearded irises is on that plot of land where there is good illumination in the first half of the day, it is better if it is a slope or hill (for the outflow of melt water) and the presence of drainage. As for marsh and Siberian irises, they are vice versa They like to keep the soil constantly moist.

But at the same time, all species love rich soil, therefore, if necessary, in the spring, before planting, compost is introduced (do not use manure) and potassium-phosphorus fertilizers. If the soil is acidic, you can add a little chalk or wood ash. And be sure, before planting, it is necessary to treat the area with herbicides and moisten with a fungicide (for disinfection).

Watering irises

It is worth watering the plant only after the soil around the bush has completely dried. If there is a possibility that groundwater passes close to the surface, then it is worth taking care of drainage in advance.

The first watering is carried out immediately after planting, and the next - not earlier than three days later.

Feeding irises in spring

For lush flowering and good growth irises, like all plants, need top dressing and fertilizers. However, manure should not be used, irises will start to hurt from it.

For top dressing, use complex mineral fertilizers containing phosphorus, nitrogen and potassium. You need to scatter it around the bushes in the spring after the irises begin to grow. After that, the earth should be watered to accelerate the dissolution of the granules.

Also, do not forget that an excess of fertilizers is also very harmful to plants, as well as their lack, it is better not to feed them a little, as with watering, than to overfeed them. Some of the gardeners may object: why feed and mess with irises, because they will bloom without it. But this is debatable.

For ten years of growing irises, there were such periods when top dressing was not carried out at all for about three years in a row - while the difference was very noticeable. If fertilizers are used, irises bloom more abundantly and much more magnificently, their flowers are brighter and larger, the leaves are healthy and glossy, and the peduncles are strong enough that even with strong wind do not break, which do not require tying at all.

But the main thing at the same time - the growth of such bushes, occurs much faster. For these reasons, the answer to the question to feed or not is unequivocal - to feed, but at the same time wisely and in moderation. I have already developed a feeding scheme with a complex of micro and macro elements once a season before the start of the flowering period. I notice from my irises that they like it, they grow very quickly and bloom gorgeously.

Preparing irises for winter

Due to the characteristic feature of irises, which consists in the fact that their root system grows horizontally, sometimes their roots are exposed above the surface, so in winter they need to be sprinkled with additional earth and peat, otherwise they will freeze. In the spring, this layer of soil is carefully removed.

Leaves, straw, corn stalks as a covering material, or any other material under which irises can rot under are categorically not suitable. For shelter it is better to use the earth. Pour some handfuls of soil into the middle of the bush in order to cover the exposed rhizomes.

When snow falls, it can also be used as a shelter, additionally adding it to the planting of irises. And in spring period, after the soil dries, the excess soil should be carefully distributed around the bushes. And yet, in the matter of sheltering irises on winter period It is impossible to give unambiguous advice for all gardeners.

Since, when growing irises in the southern regions, you can completely do without shelter for the winter period, but in the east and north of Russia, some varieties simply need preventive shelter.

Iris breeding

There are three ways to propagate irises - seeds, sprouts or rhizomes.

At the same time, the main difference between these methods is that flowering of irises grown from seeds should be expected only in the second or third year, and flowers grown from rhizomes will bloom in the first year.

Reproduction of irises by dividing the bush

When dividing a bush, only the healthiest bushes are selected. Having dug out all the rhizome from the ground, it is necessary to thoroughly shake off the whole earth in order to clearly see each root, then cut into small areas, so that each part has one leaf bundle left. The leaves are cut in half.

After that, it is necessary to carry out disinfection in a weak solution of potassium permanganate (dip the roots in the solution for 10-15 minutes), and dry in the sun. Plant in small holes, no deeper than 3-4 cm and at a distance of no closer than half a meter.

Vegetative propagation of iris

For propagation by sprouts, it is necessary to wait for at least one flowering of the plant, only after that you can safely use young shoots. At the same time, it is worth cutting them off before the buds appear.

Rooting is carried out by planting in the ground in a shady place, creating a greenhouse. Spray additionally if necessary. After 2-3 weeks, full rooting can be observed.

Iris growing from seed

After flowering, collect the dried ovaries. They can be stored in boxes in a dark and dry place. In autumn, prepared seeds are planted in pots with a sandy substrate and covered with glass or polyethylene (create a greenhouse). Closer to spring, the seedlings will sprout, they need to be thinned out.

Young growth is planted only after it has grown enough to make it convenient to plant. It is worth noting that only species irises can be propagated in this way, but with varietal irises, problems may arise with the preservation of maternal characteristics.

Bacteriosis or soft rot of iris rhizomes

One of the dangerous diseases that affects irises is soft, bacterial, root rot . The plant dies with a strong degree of infection.

Signs of this disease are the rotting of the leaves at the base of the rhizomes, while the leaves remain green and simply fall out in whole fans. The rhizomes themselves inside turn into a fetid slurry. Affected bushes should be completely dug up, cut out all damaged areas, reaching healthy tissue, each time the cutting tool should be disinfected.

The bushes are divided, the places of cuts are sprinkled with crushed coal, after which they are laid out in the sun to the top with rhizomes for one to two days, for a good warming. You should not be afraid that the irises will dry out. Such procedures are a way of salvation for diseased plants. After that, the delenki that have dried up and warmed up are transplanted to a new site, and watered.

The earth in the contaminated area is disinfected with a solution of potassium permanganate, and the contaminated material is burned. With moderate damage to the rhizomes of the disease noticed in time, it is possible to save irises in almost one hundred percent of cases.

Rust spots irises

in spring and summer periods on the leaves of irises may appear rust spots , which grow over time, causing gradual drying of the leaves. Particularly rapid spread of these spots occurs at high humidity.

To prevent leaf spotting, irises should be treated with fungicides in the spring at the very beginning of intensive plant growth, with a mandatory repetition in ten to fourteen days to consolidate the results.

And at the beginning of the flowering period, a control treatment is carried out. It should also be taken into account that solutions of drugs on the leaves are poorly retained, for this reason special adhesives should be added.
