Why does not forsythia bloom: all causes and ways to eliminate them


Forsythia (other name - Forsythia)– beautiful ornamental shrubs, a member of the olive family, which will create a wonderful feeling of warmth and spring in the first warm days. The sun-colored plant will not only improve the aesthetic appearance of your garden, but will also cause an envious glance among all passers-by. But this plant is not always able to please with its beautiful bright flowering, and in this article we will try to determine why forsythia does not bloom, and name the most common reasons for this.

Resistance of forsythia to diseases and pests

Forsythia, no matter how much time it blooms (mostly 22-25 days), unlike other garden bushes, the plant is unpretentious. Despite the early timing of the appearance of the first flowers, the bush does not require titanic efforts in its care. Most often forsaytiya sick inexperienced gardeners.

The only thing that the bush is afraid of and what causes many of its diseases is a surplus of moisture, but in a dry season it feels quite comfortable. So, the most common disease of forsythia is root rot, which is very difficult to cure, but easy to prevent.

Another serious disease that can damage forsythia is bacteriosis, which is dangerous because it spreads immediately to the nearest bushes. If this disease has already damaged your plant, then one way out: to uproot a shrub, recycle it, and disinfect the place where your shrub “lived” with a concentrated solution of potassium permanganate.

But from living pests, formatoes often attack nematodes (insects that are located in the upper layers of the soil and can damage the root system). You can fight nematodes by treating bushes and soil around the bush with Carbation.

The next pest, perhaps one of the most common on all garden plants, is aphid, which damages the leaves.

Birds that love to eat unopened plant buds can also cause irreparable damage to the plant, therefore, in order to prevent it, it is better to shelter in the fall and to cover the trunk and shoots with a fine mesh before the buds open.

As you can see, the state of forsythia depends directly on the quality and timeliness of the care provided to it.

Why does not forsythia bloom: insufficient lighting

There are several reasons why forsythia blooms poorly, and one of the most important is a small amount of light. Each plant requires a suitable place to live, the choice of which should be based not only on the quality of the soil, but also on the neighbors that grow next to the bush, and on the lighting.

Forsythia - The shrub is quite bright and requires the same lighting, and besides, it is very thermophilic. Of course, the plant will not die only because it grows in partial shade, but it’s not for nothing that the forsythia flowers are called “golden bells” or “golden lilacs”. Forsythia blooms very brightly and plentifully, and in the penumbra the color will lose its quality.

Free access to sunlight will be a good prevention of root rotting, because with good lighting, excess moisture will evaporate faster and there will be no stagnation of water.

Like many other garden bushes, Forsythia loves the place to warm and brighten, and, having provided these two conditions, you will receive a wonderful plant that will please the eye for a long time.

Errors when watering and feeding forsythia

Often found on the forums gardeners questions: how to make forsythia bloom, whether additional feeding is needed, how to water it properly. Forsythia does not require very abundant watering, watering the plant every three days, with a bucket of water under one shrub under severe drought conditions.

With a temperate climate and normal weather, the moisture that is contained in the soil is enough for a bush. In order to avoid the problem of loss of flowering quality due to waterlogging, it is necessary to provide a drainage layer during planting, using either purchased material, or crushed red brick, peat, gravel. If the forsythia is too wet or too dry, not only the color will suffer (it will become less abundant, the bright yellow color will become faded), but the leaves will also lose their decorative appearance.

Despite the fact that forsythia is unpretentious in care, she still needs fertilizing. You need to feed it properly: if in the early vegetation period, nitrogenous substances are simply necessary, then in subsequent stages of fertilizing it only hurts, and the bush will lose its color saturation.

Very important in the proper selection of forsythia fertilizers will be the fact that if the soil is sufficiently acidic, then slaked lime, which should flow into the root system for better flowering and growth, as well as normalize the pH level, can act as additional substances.

Non-compliance with pruning rules is the main mistake of novice gardeners.

One of the main factors in the care of forsythia is pruning. Even beginners are aware of the significance of this process, not only for rejuvenation, but also for the rehabilitation of the bush. Often, due to improper pruning, flowering ceases, and this happens because on the Forsythia bush flower buds are located on biennial shoots, and therefore, if you shorten the shoot, you can remove the unopened flower itself.

In order to pruning was successful, it is better to carry out it gradually, without removing all the old shoots at once.

It is conditionally possible to divide the trimming process into three stages:

  • removing old branches,
  • bush thinning
  • shortening the branches that have faded (by a third).

Neglect of the rules of wintering plants

Very often gardeners neglect the quality of the shelter, which is constructed for the bush for the winter, and the consequence is that only the lower branches bloom in the fall or the flowering in general becomes much worse. The opinion that special excitement about the “roof” is not required for Forsythia is a bit erroneous, because the branches can not only frostise, but if they are not sufficiently sheltered, birds that have remained for the winter.

Usually, they cover the trunk circle for the winter and cover the branches. You think: how can you cover a large enough bush? Very simple: the branches gently rope.

If it so happens that you had to use non-woven material, then remove such a shelter is necessary gradually. For additional shelter you can use snow.

As you can see, the health of the shrub and its appearance largely depends on the care that the plant receives, and we hope that this article will help you take care of your forsythia correctly.

Adding an article to a new collection

The blooming forsythia is an amazing sight. In the earliest spring, when there are no leaves on the trees, bright sunny flowers of this ornamental shrub bloom, literally filling you with joy all around. If your forsition does not bloom, you need to urgently correct the situation.

The reasons for the lack of flowering can be several, try to understand each of them in more detail.

First, it is necessary to understand, when the forsythia blooms, can it bloom just too early? Depending on the climate, large yellow flowers on its bare branches appear from late February to April - this is a real "primrose" among shrubs.

In general, forsythia is an unpretentious and frost-resistant plant, usually with its cultivation of labor does not occur even among novice gardeners. Her love for the constant decorative - when the golden flowers gradually disappear, the shrub is covered with dark green foliage, which by the autumn "repainted" in purple-violet. In addition, there are several types of forsythia, which you can choose to your taste.

If the forsythia refuses to please you with an early abundant flowering, it means that she does not like something on the plot. What exactly?

1. Failed landing site

Why does not forsythia bloom? Taking care of the health and convenience of the plants is necessary from the moment they are planted. Do you have comfortable forsythia? Check it out! She loves:

  • light, slightly calcareous and necessarily non-reclaimed, drained soil (for example, a mixture of leaf earth, humus and sand in a 1: 1: 2 ratio),
  • well lit place
  • windless or drafted corner.

True, easy? However, non-observance of even one of these wishes may lead to a weakening of flowering, or even its absence from forsythia.

Remember that even if initially the site for the shrub was chosen ideally, the conditions may change over time: a fence was built or nearby trees gave shade, soil moisture increased, drafts appeared, the soil was exhausted, etc. Watch this and fix the situation on time.

2. Incorrect dressing and watering.

The reason that the forsythia does not bloom may also be the wrong care for it. This is quite an unpretentious shrub, but it also needs help if you want to enjoy plenty of flowering every year.

The main mistake - excessive watering forsythia. Of course, in the dry and hot summer water is needed, but do not overdo it, because likely to cause rotting of the roots. It will be enough buckets of water under each bush every 1-2 weeks, depending on the weather.

A signal to the fact that the forsythia is over-moistened will be twisted, discolored leaves, poor flowering, faded color of the petals. After watering, carefully loosen the tree circle. In early October, watering can stop altogether.

Lack and excess of nutrition, as well as improper fertilization is another common reason that forsythia does not bloom. It will be correct to do so:

  • spring before flowering, feed forsythia with organic fertilizer, it stimulates the growth of shoots and activates the awakening of flower buds. Put the rotted manure in a sticky circle in a thick layer (about 15-20 cm) and pour plenty of warm water
  • at the beginning of flowering, plan a thorough loosening of the soil and the introduction of complex mineral fertilizer at the rate of 70-100 g per 1 sq. m,
  • in May-June (with the completion of flowering) repeat the same mineral dressing,
  • in September, offer forsythium phosphate-potassium fertilizer (superphosphate, ammophos, etc.) to increase the frost resistance of the plant - at the rate of 1-2 tbsp. under the bush.

If the soil in the plot is acidified, the obligatory item for the wellbeing of the forsythia will be the application of crushed chalk or hydrated lime, which normalize the pH level.

3. Improper pruning

Forsythia, like most cultivated garden plants, needs regular and competent sanitary and formative pruning. If it is excessively or too shortly cut, you can, by inexperience, remove the flowering shoots. If, however, the shrub is allowed to grow without pruning at all, there is a high probability that the crown will thicken, when the root system will not cope with nutrition, and the sun with a uniform illumination of such a large number of branches.

Forsythia pruning rules are simple:

  • shrub pruned after flowering, to accurately determine and not damage the two-year shoots, bearing the main number of flower buds. The faded shoots are shortened by no more than a third,
  • old branches should not be removed all at once in one year - do it gradually and evenly, leaving as the replacement the strongest growth that will bloom next year,
  • do not forget to thin out heavily thickened bushes so that nutrients are not spent on excess branches.

4. Mistakes in winter care

To ensure that the forsythia blooms in spring, it is necessary to take care of it in advance - to organize the proper wintering of the plant. This is true for regions with a harsh climate and snowless winters, and especially for the unsustainable varieties of this shrub.

To protect the forsythia flower buds from freezing, even before the first frost, a thick layer (not less than 10 cm) mulch the tree trunks with sawdust, straw or dry leaves.

Then the branches, if possible, bend down to the ground, fix and cover. If the bush is too high or voluminous and it is impossible to bend down the branches, the plant gently tightens the twine into a compact cone and again wraps it carefully.

As for covering material, you have a choice. You can take spruce spruce branches, you can breathable non-woven material (for example, lutrasil or spunbond). Avoid plastic film and other similar materials that do not allow air. When heated by the sun, they create a greenhouse effect, which can lead to untimely awakening of the kidneys and even to putrefactive processes due to high humidity.

Remove the shelter should be in early spring. Moreover, they do it gradually so that the plant has time to adapt painlessly to changing temperatures.

Inexperienced gardeners often wonder why the forsythia blooms only from below. All because of the same wrong winter shelter, when the lower branches, covered with snow or carefully covered, could save flower buds, and on the upper branches they were beaten up by frost or pecked by birds.

As you can see, it is not at all difficult to help the beauty of the forsythia to bloom regularly and profusely every year. We are waiting for a bright spring!

Incorrect trimming time

The lack of flowering of forsythia is often associated with the main mistake in the care of the shrub - the wrong time for pruning. The plant ties flower buds on annual shoots in autumn. Do not prune the plant in late summer or early spring. Pruning done immediately after flowering. Refusal to prune after color also adversely affects the development of forsythia buds in the next season. Pruning stimulates the growth of young shoots, due to which forsythia blooms more abundantly. Neglect of pruning will lead to a smaller increase in young shoots, on which the flower buds are formed.

Too little light

The shrub needs a sunny location, you need to plant in a place where the shadow will not fall most of the day. The lack of a sufficient amount of light leads to a smaller set of flower buds, small flowers, a short period of flowering. If the plant grows in a shaded place, it is better to transplant to a more sunny place, where the sun will be in abundance.

Too dry

Shrub, grows on any soil, because of the shallow root system is sensitive to the lack of water in the soil. The situation occurs more often on light sandy soils. The plant reacts to drought by withering leaves and young shoots. In dry summer, the plant loses its ability to set buds, is a consequence of damage to young shoots.

On sandy soils, shrub requires mulching with garden bark or black non-woven material, limiting the evaporation of water from the soil. In hot years, young bushes require watering, especially on light soils.

Too cold

The most beautiful flowering varieties Forsythia medium (Forsythia x intermedia) - not cold-resistant. Sometimes spring frosts damage knotted flower buds. Due to the damaged buds, there will be no flowering as a result of frost. The frost is completely stable. Forsythia ovoid (Forsythia ovata). The look has less decorative qualities. Forsythia hybrids are egg-shaped with medium forsythia withstand frost and bloom more abundantly.

Frozen branches cut to the place of live (green) tissue. In the fall, you need to protect forsythia bushes before winter, with agrotextile or straw. At the end of summer it is necessary to fertilize bushes with phosphorus-potassium fertilizers, in case of a dry autumn, to provide adequate hydration of the bushes.

Lack of fertilizer

Although the plant does not apply to shrubs that require abundant fertilizer, from time to time you need to feed. If during planting add compost, fertile humus soil or peat, the first fertilizer application is made after 3-4 years. Signal of lack of fertilizers - weak growth of shoots and weak flowering, despite the appropriate care. The shrub is fertilized in spring (March-April) and at the end of summer (not later than until the end of August). In the spring it is best to use multi-component fertilizer for flowering shrubs. In August, it is necessary to apply autumn fertilizers (potash-phosphate fertilizers) that induce the shrub to set the buds and prepare the plant for winter.

Lack of power

Undoubtedly, this shrub is quite unpretentious. But does not mean that he does not need additional feeding. It is necessary to lay manure around the plant every spring and as soon as the shrub ottsvetet make a few additional feedings, two are enough. After flowering fertilizer is recommended to take a mineral character. And if the first top dressing should be nitrogenous before flowering is important, then the subsequent must contain phosphorus, as well as potash trace elements.

An excellent fertilizer for a sunny shrub is ash, lime (only necessarily extinguished, in this state it has the ability to reduce the acidity of the soil). Lime is simply necessary for this plant, and it is necessary to fertilize the land with it. If this is not done, the forsythia root system will not receive beneficial substances because their absorption will be impaired. The quality of fertilizer affects a lot, including flowering, so you should pay attention to it. It is also important not to overfeed the bush with fertilizer, if you overdo it, the flowering will be dull.

Poor quality or improper pruning

Еще одним фактором отсутствия цветения может стать неправильное обрезание. Некоторые садоводы по неопытности не придают значение обрезке, считая эту процедуру не столь важной. And in vain. Обрезка должна проводиться ежегодно, и обрезать растение нужно, учитывая несколько правил:

  1. In forsythia, the buds of flowers begin to be laid on the shoots of 2 years old and if carried out long circumcision, the shrub will not bloom. That is why it is necessary to prune only in the spring, immediately after the shrub fades, then there is no doubt that next year it will bloom again.
  2. The next important rule is the technology of circumcision itself, the branches should be trimmed evenly, one by one, and not all at once.

Many flower growers and gardeners run this plant, and do not prune it, which is why it ceases to bloom. It is necessary to annually pruning, remove all old dried stems. If a large shrub needs to be thinned, a large number of branches prevents the plant from getting nutrients. And the lack of a sufficient amount of top dressing, respectively, leads to the fact that the bush does not have enough strength to bloom.

Lack of light

Lack of light can also affect flowering shrubs. This plant loves light and heat, therefore the place where it will grow is necessary, to choose, considering this factor. And also choose the right flowers that will coexist with him, plant only those that will not be able to interfere light entering the forsythia.

Wrong preparation for the winter period

Forsythia does not like the cold, so it is necessary to prepare it for wintering in the fall. True, not all gardeners are able to do it right, and some do not prepare at all, and the shrub is not closed. And next year, the lower branches bloom, but the upper ones do not. And even the whole flower is left without buds. If only the bottom blooms in the bushes, then most likely, the upper buds are pecked by the birds, or the lower part was just under the snow and did not freeze, unlike the upper one, which was on the surface.

It is precisely in order that the forsythia can successfully overwinter, it must be sheltered for the winter and carefully make insulation wheel circle and branches. And as the snow will fall, powder them with a bush, and then it will remain intact. Forsythia has some varieties that are cold-resistant and they do not die, but their flower buds freeze and do not bloom in spring.

Many will find this work difficult and impossible, because the shrub is quite large and the branches are long. That is why, in order to cover a bush, you must first properly prepare it. Initially, you need to carefully tie it with a rope or a special twine, then it will be much easier to cover the shrub. For shelter it is not recommended to use polyethylene or similar materials that do not allow air to pass through. Such materials may cause an untimely awakening. If this happens, the bush will die. The ideal material for shelter is lutrasil.

If used for shelter nonwoven fabricthen it is necessary to open it in spring gradually so that the shrub has time to adapt. Other covering materials can be opened immediately, special recommendations are not required. When buying seedlings, it is necessary to take into account the climatic conditions of the region in which the solar forsythia will grow, and acquire only those that are suitable for cultivation.

Why the forsythia does not bloom, many factors can affect, and each of these factors is very important. Even abundant feeding and correctly carried out pruning will not give one hundred percent confidence that the forsythia will bloom. The reason may lie in the fact that flower buds simply froze out during the winter cold. It is necessary to carefully monitor the shrub and do not ignore the recommendations for caring for it, because it will depend on it whether it starts to bloom or not.

If we carry out all the manipulations in a timely manner and according to the rules, there is no doubt that in early spring the forsythia will bloom and will delight with its abundant and bright blooms for a long period.

European forsythia

Such a shrub in open ground is recommended to be planted on bright and sunny areas. In this case, it is necessary to take into account the fact that adult forsythia can grow very large and reach a height of 2 meters.

The most suitable season for planting a bush is late autumn, before the first frosts.

Abundant flowering shrubs will be provided in sunny areas, in the shade it will become a bit poorer.

At home, when planting, forsythia should be ensured the lightness of the soil and its permeability.

In the event that it is planned to plant several bushes of this plant side by side, one should maintain a distance of at least 2.5 m between them. If there is an intention to organize a hedge from forsythia, the bushes are planted in 1 m steps.

The depth of the landing pit should take into account the presence of a drainage layer, 20 cm, a layer of sand 10 cm. At the same time, the soil should be equipped with humus, wood ash or lime slaked (subject to high levels of soil acidity).

Recently planted bushes must be sufficiently watered and mulched. Before the first wintering bushes should be covered from frost, pinned them to the soil, or covering the breathing material.

In the spring, when the threat of recurrent frosts will be minimal, the bushes open, cleaned of protection and fertilize the tree trunk with humus.

Especially in fertilizers, forsythia bushes need before flowering and after it. From the beginning, mineral complexes are needed, then - potassium-phosphorus e.

The shrub does not need frequent and abundant watering, it has enough natural precipitation. If the season turned out to be dry, then once a month it will be necessary to pour 12 liters of water under each bush.

Care and circumcision

The main condition for good development of the bush and abundant flowering is competent pruning. In this case, the main thing is not to overdo it, because with an excessive removal of the branches, they will branch out much in the coming year, but it is scarce or not at all to bloom.

In the first years of the life of young bushes they are pruned gently. For the most part, only damaged areas of shoots are pruned.

Provided the formation of a hedge, pruned subject to all branches, which are knocked out of the overall picture. It does not affect the condition of the shrub.

In the matured bushes, all the shoots that were with inflorescences are shortened by half. The cut must be done over a healthy kidney.

To activate the emergence of new shoots from the lower buds, damaged branches are removed at a distance of 5 cm from the ground surface.

In addition, perform wellness pruning, which does not allow the bushes to thicken unnecessarily. In order to rejuvenate forsythia, it is necessary to cut branches by two thirds every three years. What activates the growth of new shoots from the root.

Lonely growing bushes of this species, as a rule, do not cut too much. They are allowed to grow arbitrarily. Only once every three years do corrective pruning to give the bush a neat shape.

Why does not forsythia bloom?

The lack of flowering shrubs can happen due to insufficient nutrition, improper pruning.

If you want to enjoy the flowering of forsythia in the current year, you should know that flower buds are laid on 2-3-year-old sprouts. And if you remove them, the shrub will not bloom.

In order to determine the flowering branches for sure, pruning should be done in the spring, immediately after flowering. Old shoots should be removed gradually, but not all at once.

Forsythia soil composition and flowering

Forsythia is undoubtedly an unpretentious shrub, but this does not mean that it is necessary to forget about feeding it forever. We plant a plant on a nutrient, loose soil. Water should not stagnate, which prevents the forsythia from blooming, but poor soil will not contribute to the formation of inflorescences.

How to feed: standing manure, mullein, bird droppings. Bring organic matter only in early spring after the ground warms up. It stimulates the build-up of shoots, promotes the laying of the kidneys and gives them energy to expose. In the same period, mineral nitrogen fertilizers are also applicable: ammonium nitrate, urea. During the laying of flower buds, their surplus is just may be the reason why forsythia does not bloom.Acidification of the soil causes a similar effect. It can be deacidified with available wood ash, lime or chalk - a component of your choice - which is added 2 weeks after fertilization.

Seasonal pruning - prevent thickening

Forsythia trimming is one of the important procedures. After winter, the gardener needs to remove old branches, thickened 3-year-olds, as well as the dead and thickening the bush. We should take care of this in the spring. Faded shoots at the end of autumn are also removed. Improper pruning leads to the fact that forsythia does not bloom.

How to trim: Dried and old, thick branches are removed at the base, and shoots that thicken the crown are shortened from above. Strong branches - this is the middle of the bush. 20 cm cuttings can be used for further reproduction.

Watering and loosening forsythia

Active watering begins when the soil warms up, then declines again in early summer. To preserve moisture, the ground is mulched. HFrequency of watering 1-2.5 times per month, depending on weather conditions - dry spring or summer = more abundant watering - 12 liters per bush. It is necessary to complete the procedure of moistening loosening soil mix to a depth of 1 shovel blade; and remove weedswhich impede the access of oxygen and nutrients to the root system.

Neglect of preparation for the winter

Not every summer resident responsibly treats autumn work, and sometimes they simply do not have enough time. But it is important to shelter such a gentle shrub as forsythia. Why only lower branches bloom, while the upper part remains naked? There may be two simple explanations: either the flower buds were pecked by wintering birds, or simply because the lower part of the bush was under a layer of snow. In either case, only good covering material will help you, which will save the forsythia.
Many varieties of this shrub stand frost well, they often survive without loss even in very cold winters. But if the branches remain whole, then the flower buds are damaged even at low temperatures. Therefore, try to set aside time in the fall and prepare forsythia for the winter: warm the tree trunk, cover the branches. And when the snow falls, it will be possible to additionally sprinkle it around the edges to protect them intact.

For an inexperienced summer resident such work will seem impossible, because the bush is often vigorous. The fact is that he is cautiously at first tied up with a string, so that it is more convenient to wind it with a covering material. Well, by the way, lutrasil is suitable for this purpose. It is better not to use polyethylene film and other materials that “do not breathe”, because when heated by the sun they can provoke an untimely awakening, because they do not let the air through. The bush in this case will surely perish.
If you used non-woven material for cover, then try to remove it gradually so that Forsythia can adapt. Other types of shelters can be removed immediately. But, most importantly, always be guided by your climate, purchase varieties that are exactly suitable for growing in your lane.

Many factors influence the forsythia bloom, and each of them is important. Even if she gets a good feeding, and you will prune according to the rules, the problem may lie in the fact that the kidneys simply freeze out. Try to balance the attention to it and do not lose sight of any of all the factors that can affect the flowering bush, because it is not so difficult. But in the spring, when the rest of the trees are still asleep, you will enjoy bright colors, knowing that in this lush abundant bloom there is also your considerable merit.
