With proper planting back rhizomes should be directed to the south. Thus it is fully warmed up in the sun that stimulates the laying of flower buds. Autumn when the temperature drops to 5 ° C, fold back to pleased flower blooming in the next season.

When irises do not blossom because they are too recessed into the ground, it is not recommended to dig them, because you can hurt the root system. Try a little bare neck, removing 1 cm of soil. Hopes to bloom after such a procedure should not be, but it can help to prevent the decay of rhizomes. Extremely rare rhizome itself comes to the surface. Basically this happens, if the plant is planted in loose soil.

Reason 2. Iris is not enough lighting

Irises like sunlight, so the best place for them is sufficiently well lit section. If you put them in the shade or partial shade, flowering will be poor or do not come.

Easily correct the situation - move the bushes in a more favorable position. Such a plan will transfer procedure irises well, as they need a transplant every 5 years. This is best done in late July or August.

Sometimes it happens that the irises bloom from year to year, but one day cease. In this case, you need to see where they have grown over this period. Probably, the bushes were in a place devoid of sunlight.

Reason 3. Irises suffer from excessive watering or lack of

Irises are considered low-maintenance plant, so they tolerate drought without problems and do not need frequent watering. However, there are situations where the moisture it badly needed:

In the first 2-3 weeks after planting;
during budding.

If for some reason in these times you do not provide plants with proper care, most likely, it is not bloom, because the lack of moisture prevents the formation of healthy buds and disturbs root growth system. The same applies to the excess moisture. If you abuse irrigation, there will rot, buds and leaves become flaccid, and the flower may die. To fully develop a plant and pleasing flowering, should be regularly watered it and monitor the status of the soil.

What if the irises have been damaged caused by improper watering? Dry plants should be watered abundantly, and the procedure to be repeated, when the water is absorbed. Rotten plants need to dig, remove the rot from the roots and send out to dry in the sun. In a place where there were irises should replace the old ground fresh.

If the summer is too hot, blooming irises require timely watering. The ideal time for such a procedure - evening. Watering the plant is necessary so that water does not leak to the flowers.

It is possible that the iris season will not be able to bloom, but your task - to save the plant. Begin to act as soon as you realize that the irises are not blooming because of the lack of moisture.

Reason 4. Iris does not have enough nutrients

Another important condition for the full development of their irises and elegant flowering - a regular fertilizing. Basically dressing is carried out in three stages. The plant is fertilized twice before flowering and once - after. What will signal that the flowers need nutrients? In fact, to understand it is not always easy, since they can not change their appearance. However, there are certain features that you should consider:

buds fall off;
the plant does not bloom;
the plant grows slowly;
root system stops in development;
dry leaves on the edges and twisted inside.

If this is the nutrient deficiency, it does not mean that you need to immediately make the fertilizer in bulk, otherwise the plant will experience stress. It is best to start with nitrogen and potassium recharge. To do this, add ammonium nitrate and potassium sulfate (15-25 g per 1 sq. m.). After two weeks, you need to be repeated procedure. At this time, we need to triple superphosphate (25-30 g per 1 sq. m.) and the same amount of ammonium nitrate.

Adding organic matter such as manure, can lead to the death of flowers. After feeding such fertilizer may occur root rot. Flowering will be poor or completely stopped. Feed irises organic fertilizers can only manure after water dilution (1:20).

The feed for lush flowering irises

Irises to bloom luxuriantly, and the buds have turned out strong and large, as a make-up can be used:

Wood ash (at 2 tbsp. l. each bush);
Leaf humus. They need zamulchirovat area roots and slightly loosen the ground.
Minced fish. Mix 400 g of product with 10 liters of water. Spend watering every other day. Make fertilizer directly under the root. Two weeks before flowering, the fertilizer should not be performed.

Reason 5. Iris tightly on the flowerbed

The roots of irises grow quite actively, so once they are encouraged to share and to land on another place in 4-5 years. If during this period you did not carry out this procedure, your landing will be too thickened, and therefore cease irises bloom. It can also cause a number of diseases and pests cause. Solves the problem easily: at the end of July and in August, divide irises. Carefully lift out the roots from the ground, cut them into delenki clean them from rot and break the plant in a place that is well lit. If you give him favorable conditions, it is bound to bloom in the next season. When planting iris rhizomes should be maintained between a minimum spacing of 40 cm.

Reason 6. Iris rhizome rot last summer

If the past summer was cold and rainy, most likely, will refuse irises bloom. Excess moisture leads to root rot. To save the plant, watering should be moderate. In August, they need to dig and cut all the areas where there is a rot. Disinfect sections solutions of potassium permanganate, and the soil at the new location for the irises treat antifungal drug. As a final ideal "fitosporin".

Reason 7. Irises suffered during hibernation

If you leave the winter irises without protective cover, their flower buds will not be able to withstand the impact of sub-zero temperatures. The plant itself will be developed without a hint of feeling unwell. Understand that it has suffered in the winter will be possible at once. Even Siberian irises, which are characterized by high resistance to frost, may refuse to bloom. To prevent this, you need only to hide the plants before the arrival of cold weather spunbond or spruce spruce branches.

It is not necessary to conceal the flowers too early, because the plants can rot, it will also cause lack of blooms. It is better to do so with the arrival of the first frost (in November).

If you suspect that the plant has experienced stress during the winter due to lack of protective cover, inspect the roots, not removing them from the earth. You can wash the roots with water, so that the damage was more noticeable. Dark soft parts must be cut with a knife Edged well. Places slices and sprinkle prikopalis coal in the ground. If the damage is severe, it is necessary to dig up and separate the bush healthy roots.

Reason 8. Irises amazed by diseases and pests

Lack of flowering may be associated with disease and pest irises. Sometimes it can go together with thickening of landings, and after freezing of the winter, when the plant is weakened.

To find out the condition of the plant, it is necessary to conduct a thorough examination of the bushes. As a rule, their strikes Fusarium dry rot, leaf spot, rust. These diseases can be prevented by treatment bushes fungicides.

If we talk about the pests, the irises are often attacked by cutworms, which devour the flower stalks and thus does not allow the plant to bloom. These insects can damage the roots, causing the iris soon begin to rot.

Danger provides gladiolusovye thrips, which settle on the leaves and result in violation of photosynthesis. If the leaves have started to dry up - this is one of the signs of the invasion of such pests.

In some cases, the iris may refuse to bloom due medvedok and larvae of beetles. Inflict great harm and slugs.

The massive accumulation of insects - a reason to use insecticides. Pest control can also be used folk remedies. Good effect decoction of wormwood (1 kg of raw material in 3 L water), celandine broth (250 g of crushed leaves in 1 liter of water). The liquid to infuse for two days, after which it can be sprayed bushes (1 time 5 days).

Reason 9. varieties of iris feature

If you follow all the rules of landing irises and provide them with appropriate care, but they are in no hurry to bloom, it is possible that the reason lies in their grade. They each have their own terms of flowering and growth characteristics. For example, Siberian irises like acid soil, bearded as such conditions are not suitable.

In order not to run into this problem before you buy a plant, learn, child whether or not a grade to the climatic conditions in your area, on what grounds it feels good.

If the irises will be provided with favorable conditions, and they will not suffer from improper care, rest assured they will delight you with elegant flowers, exudes a lively delicate flavor.
