Why irises do not bloom: some leaves, what to do, causes and treatment

Flowering iris is a great decoration for any flower bed. Some gardeners in the process of growing this flower are faced with the fact that it stops blooming. To get rid of this problem, you need to figure out why irises do not bloom and what to do if there are only leaves and no flowers on the bushes.

Irises do not bloom: reasons

There are several reasons why the Siberian iris may not bloom. It is recommended that you familiarize yourself with the common causes of flowering problems in more detail.

Landing errors

Most often, flowers do not bloom due to improper planting. Many inexperienced gardeners plant seed in holes that are too deep. Because of this, plants will not only bloom worse, but also grow more slowly.

Checking that the plant is planted correctly is pretty easy. To do this, carefully examine the root collar. If it is dug into the ground by only a third, then the flowers are planted shallowly. When the neck is in the soil, it lacks sunlight, which negatively affects growth. In this case, you will have to dig up the seedlings and transplant. At the same time, they must be dug out carefully so as not to damage the root system.

Wrong place

The growth and flowering of plants is affected by the place where they are grown. Therefore, experienced flower growers recommend taking seriously the choice of a site for planting irises.

These are light-loving plants that need to be planted in well-lit areas. Without enough sunlight, the plant will grow slowly and bloom poorly. To solve the problem with poor lighting, irises will have to be transplanted to another place. Transplanting is best done in early August or late July.This is the most favorable period for planting crops. They are transplanted to open areas that are not shaded by buildings, trees or tall bushes.

Food shortage

Any plant needs periodic feeding, and irises are no exception. These flowers can fully develop only with regular fertilization of the soil. If you do not feed the planted flowers, they will bloom worse. Fertilizers are applied to the soil three times a season. The first two times the crops are fed before flowering, and the third time after.

There are several signs that indicate a lack of nutrients:

• fallen buds;
• slow stem growth;
• twisting and drying leaves;
• delayed root development.

If it turns out that the irises do not bloom due to a lack of fertilizers, you must immediately add mineral and organic top dressing to the flower bed.

Wrong watering

Some flower growers believe that irises do not need to be watered, as they cope well with drought. However, without regular watering, they do not bloom, because with a lack of moisture, root growth worsens and bud formation stops.

Also, flowering is negatively affected by excessive soil moisture, which rises due to too frequent watering. Wet soil contributes to the development of rotting of the root system. Therefore, during irrigation, it is recommended to monitor the condition of the soil.

If the flowers have already suffered due to lack of moisture, it is recommended to fill them with water several times.

Growth of the root system

A characteristic feature of irises is that their root system grows rapidly. The roots of seedlings that are planted too close to each other become crowded and develop more slowly. This leads to a slowdown in the development of the stem and the cessation of flowering. In addition, due to crowded seedlings, immunity weakens, and they often get sick and are attacked by pests.

To solve this problem every 4-6 years planted iris bushes are planted in new places. At the same time, they should be planted in more spacious flower beds so that neighboring plants do not interfere with the planted irises.

Winter Damage

There are times when irises stop blooming after a harsh and frosty winter. Most often, this happens if you do not cover the flower bed with covering material in the fall, which protects the seedlings from low temperatures.It is difficult to notice the consequences of an unsuccessful wintering, since they do not appear immediately. At first, the plant develops normally, but over time, you can notice that flower buds do not form on them.

To timely identify damaged plants, you need to carefully examine their stems and leaves, which may appear dark spots. All damaged areas of flowers will have to be cut with a knife.

Diseases or pests

Another common reason for the deterioration of flowering is the attack of pests and the appearance of diseases. Most often, diseases appear after a weakening of plant immunity, which is observed after winter freezing of the roots or due to dense plantings.

In order to determine the symptoms of a particular pathology in time, it is necessary to regularly conduct a visual inspection of flowers. Yellowing of the leaves indicates the presence of diseases such as dry rot, fusarium, rust and spotting.To prevent the development of diseases, plants are periodically treated with fungicidal solutions.

Bad weather

Sometimes flowering stops due to adverse weather conditions. Irises do not bloom in high humidity, when it often rains. Also, flowering problems occur with sudden changes in temperature.

How to properly care?

In order for irises to bloom normally, you need to properly care for them.

Irrigation

It's no secret that irises need to be watered periodically to keep them from drying out. Particular attention is paid to moisture in dry weather, when the soil dries quickly. On such days, it is irrigated every two days. Daily watering of irises is contraindicated, because due to excessive moisture, the root system accumulates too much water, which negatively affects the wintering of plants.

When watering, use heated and separated water. It is poured under the root of the flowers so that the liquid does not fall on their leaves.

Cutting

Iris cutting is carried out after the flowers have completely dried. To carry out this procedure, use special garden shears. First, the inflorescence is removed, after which the flowering shoot is cut off. After pruning, a cut stem 1-2 centimeters high should remain above the ground surface.

Some prune during the flowering period, but this should not be done. At this time, the plant actively accumulates nutrients for further wintering.

Feeding

When carrying out top dressing of irises, phosphorus-potassium fertilizers are used, which stimulate the growth of flower buds. To prepare a feeding solution, 20 grams of phosphorus and potassium are added to five liters of water. The prepared mixture is enough to water 4-5 bushes.

Experienced flower growers do not advise fertilizing flowers with manure, as root rot may appear due to it. It is also necessary to add less nitrogen fertilizing, due to which the growth of buds worsens. If irises are grown in acidic soil, the area is periodically watered with lime mixture or wood ash.

How to stimulate the flowering of a plant?

In order for a flower to bloom exactly in autumn or summer, you need to familiarize yourself with the features of stimulating the process.

It is known that in adverse conditions, irises bloom extremely rarely. Therefore, to stimulate the appearance of buds, care must be taken to ensure that the plant has enough nutrients and moisture. Irises need to be periodically watered and fed with fertilizers. You should also take care of the lighting of the flowers and transplant them to an area that is constantly illuminated by sunlight.

Conclusion

Gardeners sometimes have to deal with poor flowering of planted irises. To get rid of this problem, you need to familiarize yourself with the causes of its occurrence and the features of stimulating flowering.
