Why does clerodendrum not bloom, the leaves turn yellow and fall off, how to make it bloom

Lush white and crimson clusters of delicate flowers of Thompson's clerodendrum against the background of lush green wide leaves in the shape of hearts are a wonderful decoration for an apartment, office or winter garden. However, often gardeners who have chosen this plant are faced with the fact that it does not want to bloom, or the flowering gradually weakens and comes to naught. The reasons for this phenomenon may be different. Most likely, Thompson's clerodendrum does not bloom because it is not cared for correctly.

It is also possible that this trouble is a consequence of a disease or attack by pests. If you create comfortable conditions for the plant, identify and treat the disease, or rid it of parasites, intricate bright two-color “lanterns” will again appear on the beautiful clerodendrum, which will bloom profusely and for a long time, from early spring to mid-autumn.

Why does clerodendrum not bloom?

Many flower growers believe that this flower has good energy and brings feminine happiness to the home. The green beauty is a lover of the warmth of the African and American tropics. There its vines reach up to 4 m in length, green leaves cover the entire length of the shoots every year, falling off during cold weather. The shoots become woody, which allows this plant to be grown as a tree or bush.

Flowering of a contrasting beauty

Flowering occurs from the beginning of spring until the first days of autumn. At home, you can most often find Mrs. Thompson's clerodendrum and Clerodendrum Prospero. For the Thomson and Clerodendrum Prospero species, home care is the same, they differ only in shape and color palette.

If left long, the plant may pull its shoots upward, requiring garter, or fall down from the hanging pot

The conditions for keeping the evergreen representative of the Verbenov family are simple. The lack of flowering is associated precisely with insufficient care. Main reasons:

improper care during plant hibernation;
improper exit from a state of rest;
lack of fertilizing or untimely replacement of soil;
incorrect pruning.

Reproduction

You can propagate clerodendrum at home using:

Chereshkov.
Semyon.

Reproduction directly depends on the type of flower. Let's look at the varieties and their propagation:

Most beautiful. Propagated by petioles. The optimal period is from the first month of winter to the first month of spring. It is best to plant at the end of February. After the first shoots appear, they are planted in pots. All that is then required is thorough watering and a temperature range of 16°C to 20°C. The flower should bloom in the year it is planted.
Fragrant. For propagation, cuttings are used, or a piece of the root can be used. Planting is carried out when the temperature rises to 19°C. After successful rooting and the appearance of the first shoots, the plant is planted in separate pots. Water generously. As soon as the roots have become stronger and started to develop, the flower is transplanted into a larger pot. The young vine is pinched several times, this way side shoots will develop. The next year the flower is moved to an even larger pot.
Brilliant. Propagated using cuttings. Young petioles are planted in new pots, and the room temperature should fluctuate around 22-25°C. One cutting is planted in one pot. When using a larger pot, planting several cuttings is acceptable. Once they are firmly rooted, there is no need to plant them.
Clerodendrum Thompson. This type of flower can be propagated either by half-lignified cuttings or by seeds. About 5 cuttings can be planted in one pot (diameter 7-9 centimeters). You can root the cut shoots by lowering them into water. When the root system is formed, they are transplanted into separate flowerpots and placed in a shaded place. In the year of planting, they need to be pinched a couple of times. Flowers can be observed the next year after planting.

Difficulties in home care

Why do dracaena leaves turn yellow and fall off?

You should take special care of your phytofriend during periods of dormancy and recovery from it. With the onset of winter, it should be placed in a place where the temperature will be about 15 °C. Watering should be reduced to a minimum, but make sure that the soil in the pot does not dry out completely.

Important! In winter, you cannot spray, fertilize, or place the plant in a warm place.

Since watering is reduced, many gardeners forget about their indoor friend and may miss the appearance of the first buds of flower stalks. With their pipping, the active period of caring for the plant should begin, this is approximately the end of February - beginning of March:

Mandatory pruning. The length of the shoots should be reduced by one third. If long lashes are formed, you need to remove a minimum of length; if you want to create a tree, you can leave 10 cm of shoots. The smaller the shoots of the plant, the larger and denser its flowers will be.
Replanting or updating the top layer of soil. The flower slept in winter, and during the active period of growth it needs a lot of nutrients, which should be in its soil. Replanting is not necessary if the plant's roots have not reached the bottom of the pot.
After transplanting and pruning, it is important to provide the clerodendrum with warmth and plenty of light.
In conditions of awakening, the flower needs daily watering with the obligatory removal of excess water from the pan.

An example of how to prune clerodendrum correctly

How to care?

Temperature .
Since the natural habitat of clerodendrum is a hot climate, it requires a special temperature regime of 18–25°C during the flowering period. But you should avoid direct sunlight, which can harm the plant. It is better to place the flower on windows facing east and west. If the window is south-facing, additional protection from exposure to bright sun will be required.
Humidity . For lush and regular flowering, the plant requires a constant high level of humidity. The flower should be sprayed regularly. You can place the flower pot in a tray filled with damp moss.
Watering . Watering should be regular, but the plant should not be flooded. You just need to make sure that the earthen ball is always slightly moist and does not dry out. In winter, watering is reduced to 2 times a month. You should not place the plant next to radiators.
Feeding . It is necessary to feed clerodendrum during the flowering period 2 times a month with complex fertilizers.
Trimming .
In order for the plant to have a beautiful shape and bloom luxuriantly, it requires regular pruning. Shoots that are too long need to be shortened by 10-15 cm. This will stimulate the formation of new branches and inflorescences. Pruning is also necessary because the plant can grow up to 3-4 meters in height, so its growth must be limited. The shape and size of the plant must be adjusted based on the available space in the room where it grows.
Transfer. Replanting a flower should be done only after pruning. Clerodendrum does not like it, so this procedure must be done with extreme caution. It is best to do this once every 2 years.
With each transplant, the plant pot should be 2-3 cm larger in height and width. A 3 cm thick drainage is required. The support must be installed directly into the pot.
Advice! The safest and least traumatic way to transplant clerodendrum is to transfer it with a lump of soil on the roots.
It is better to buy universal soil for flowering plants in a store. But you can prepare the substrate at home: peat, leaf soil and sand in equal proportions.

Transfer

Why do cyclamen leaves turn yellow when it blooms?

It needs replanting annually, since the root system is very developed and grows quickly. More often than not, it looks more like a transshipment than a transfer. The roots of the plant are very delicate, it is better not to touch them.

Note! You cannot remove the roots too much from the soil, as you can damage them, which can also cause a lack of flowering.

The flower is picky about soil: it needs nutritious, slightly acidic soil. To create these conditions, you need to mix in equal parts:

clay soil;
leaf soil;
peat;
coarse sand.

Note! Before transplanting, the soil is disinfected with steam or in the oven.

Problems when growing Ugandan clerodendrum

Diseases of this crop are most often associated with improper care. Poor health of a flower can be easily recognized by its appearance. For example, leaves turn yellow and fall off if there is no watering for a long time. When kept in a room with dry air for a long time, the leaves and buds begin to fall off. Dark spots on the leaf blades occur as a result of Ugandan clerodendrum being in a draft. Direct sunlight burns the leaf blades, and soon brown spots appear on them. Excessive watering leads to rotting of the root system.

The most common pests of Ugandan clerodendrum are spider mites, which settle on the lower part of the leaves. A white cobweb on the plant will help you detect them. To get rid of the insect, you should wipe the leaf blades with a soapy solution, or treat the bush with an insecticide.

A decoction of onion peels or garlic is effective against spider mites. One of the components is boiled in water for 5 minutes, then diluted with boiled, cooled water in a 1:1 ratio, after which the plant is sprayed with it.

If aphids are detected, the leaves should be wiped with laundry soap concentrate. To make it, a bar of soap is grated and dissolved in boiled, cooled water in a 1:1 ratio. You can wipe the leaves manually or use a sprayer.

If scale insects have settled on a bush, you will have to resort to using a chemical preparation, since it is difficult to fight this insect with folk remedies. Actellik works most effectively in this case.

The reason for the lack of flowers is also a lack of potassium and phosphorus in the soil. It is necessary to feed the plant with fertilizer containing these substances. But even with an excess of fertilizers, Ugandan clerodendrum will not bloom.

Perhaps the flower has not been replanted for a long time and the soil has exhausted its resource.

Another common reason for the lack of flowering is too large a container, in which the bush mainly grows green mass.

Conditions for lush flowering

Why do indoor balsam leaves turn yellow?

Flower growers, wondering why their Thompson clerodendrum does not bloom, attribute capriciousness and a difficult character to the plant. And it just requires similar conditions to its native home: light, warmth, humidity and abundant watering that does not linger in the roots.

It will not be difficult to provide it with light; it feels great on a western or eastern window, the main thing is diffused lighting. During the winter dormant period, it does not need abundant light. But when emerging from hibernation, a lack of light can cause flower buds to fall off.
The temperature in summer should be 20-25 °C. During the rest period, the temperature should not exceed 18 °C, ideally 12 °C.
High humidity should be maintained by frequent spraying and a damp layer of expanded clay in the base of the pot. When spraying, it is important that water does not fall on the inflorescences.
Abundant watering begins in early spring after pruning and replanting the plant. With the onset of the dormant period, along with a sharp drop in temperature, watering is also reduced.
Complex fertilizer for flowering plants will provide all the necessary minerals and trace elements during active flowering and growth.

Important! There is no need to fertilize during the autumn and winter periods, since the plant can go into active growth and skip the period of sleep, and with it the formation of buds with future flowers.

Features and appearance

Clerodendrum is a perennial from the Verbenov family. "Clerodendrum" is translated from Greek as "tree of destiny."

The natural habitat of this evergreen, deciduous vine is the territory of Africa and Asia. Clerodendrum leaves are heart-shaped and arranged oppositely on the stems . The flowers of this plant are most decorative; they are collected in corymbs or paniculate inflorescences. Each variety of vine has its own unique delicate aroma.

One of the most beautifully flowering representatives of cledorums is Clerodendrum Philippine. This is the most decorative and unpretentious species for keeping indoors.

In Clerodendrum Philippine, flowering begins in mid-spring and continues until the last month of summer . White-pink inflorescences are collected in a large dense bouquet with a diameter of up to 20 cm.

The buds in the bouquet are about 2-3 cm, very similar to small roses with dense petals. Thanks to them and the dark green velvety leaves, this type of clerodendrum looks very decorative.

When the plant blooms, a very strong and pleasant aroma spreads around it, very similar to the smell of jasmine, especially at night. Therefore, it is better not to place this flower in the bedroom. The dormant period of this species is shorter than that of other clerodendrum species.

Clerodendrum: how to make it bloom

There is one secret what to do to make indoor clerodendrum bloom. There is one sure way to provoke flowering - pruning.

The first buds to appear on the plant are the flower buds, and then the leaf buds. If the plant does not produce them on its own in early March, the plant should be pruned. Pruning must be done sparingly, the shorter the better. After the procedure, the plant should be transplanted into fertile soil. With this method of breaking dormancy, leaf buds first appear and its large green leaves begin to open, followed by active growth of flower buds.

When and how does flowering occur?

ATTENTION: The plant begins to bloom in early June. The end of flowering is usually in September. But there are types of vines that can bloom all year round.

These beautifully flowering vines are rich in a variety of inflorescence shapes and have a multifaceted palette of colors. For example, Thompson has bright white and crimson flowers. The Beautiful Clerodendrum has purple flowers collected in paniculate inflorescences. And Fragrant blooms with fluffy white-pink flowers and, with proper care, its flowering continues all year round.

Why do clerodendrum leaves turn yellow and fall off?

Why do clerodendrum leaves turn yellow, and what to do in this case:

During the spring and summer periods, the leaves will turn yellow with poor watering. It should be made plentiful.
If the leaf blade does not turn completely yellow, but only yellow dots appear, the problem is not watering. This is a sign of the disease chlorosis. The plant lacks iron in the soil and fertilizing; you need to add this element to restore color. Sometimes chlorosis occurs when there is a sharp change in temperature at different times of the day.
If the leaves of clerodendrum lighten and fall off at the beginning of autumn or the dormant period, this is a normal phenomenon for clerodendrum. It prepares for winter and reserves strength, so it allows the foliage to turn yellow and fall off.

Lack of care leads to loss of healthy appearance

Characteristics and species diversity of the clerodendrum flower

The natural distribution area of the genus Clerodendrum is concentrated in the tropics of Africa, southeastern and southern Asia. It also grows on the South American and Australian continents, is present in the subtropics, and several species even in temperate climates (mainly in eastern Asia).

The Latin name of this plant genus is related to the Greek words “kleros” (fate, chance, fate) and “dendron” (tree). In the ancient world it was used in religious rituals and medicine.

There are both evergreen representatives of the genus and deciduous ones. Life forms are different: vines, shrubs and small trees. On olive-green or red-brown branched shoots, simple petiolate leaves with or without denticles along the edges are placed opposite. The shape of the leaf blades is oval, heart-shaped or ovoid. The length of the leaves reaches 15-20 cm. The color is dark green or emerald.

Clerodendrum Bunge

The deciduous bush Bunge of Chinese origin grows quickly, rising up to 80 cm. The leaves are whorled, broadly oval, dark green. Leaf plates flooded with sunlight take on a purple hue.

Clerodendrum Bunge

Ball-shaped (or cap-like) inflorescences up to 15 cm in diameter consist of many small pinkish flowers, individually resembling stars, and together - fireworks. They are fragrant, but dense leaves, on the contrary, smell unpleasant when pressed. Bunge blooms all summer and is resistant to pests and diseases.

Clerodendrum Prospero

This is a popular variety native to the subtropics of India, Bangladesh, Nepal - clerodendrum Wallich (or Wallich, Wallich - in different transcriptions). The room has a modest size - up to 50 cm. The branches are long and flexible, green-red.

Clerodendrum Prospero

The leaves are dark green, glossy, lanceolate, up to 15 cm in length. The buds bloom from the end of August for 1.5-2 months. The inflorescences, inclined in different directions, are decorated with fairly large (2.5-3 cm) cream flowers with 5 oval petals and very long stamens. All this resembles a bride's veil. Prospero loves plenty of diffused light.

Clerodendrum Speciosum

This evergreen spreading species is often cultivated in a hanging form (it can be converted into a bush). It is capable of growing up to 3 m. Another name “most beautiful” was given to it thanks to the flowers with a soft purple bract and a pronounced red corolla.

Clerodendrum Speciosum

Blooms from July to September on apical paniculate inflorescences. The petioles of Speciosum are fleecy, long, dull red, and the leaves are large, bright green, oval, with a pointed end.

Clerodendrum Schmidt

The shrub has dense drooping shoots, on which are located bright green oblong leaves with wavy edges. A special difference is that it blooms in a scattering of small white flowers that exude a sweet aroma. Clerodendrum Schmidt (also called Chains of Glory) blooms primarily in winter. With good care, this process can occur twice during the year.

Clerodendrum Schmidt

Clerodendrum: proper pruning

Pruning is an important procedure for this flowering plant friend. It is on young shoots that good flowers form. To provoke the growth of young shoots, you need to cut off the old ones. The shoots should be shortened by at least 1/3 of the length.

Using pruning, you can form a tree, bush or long vines that will entwine the support

Even though clerodendrum requires attention at the beginning of spring, it rewards this care with beautiful flowering. Its flowers look bright and festive and exude a honey aroma. This is a worthy decoration for any home.

Diseases and pests

The main problem of many novice gardeners is frequent watering in cool weather, non-compliance with the light regime, and drafts. Temperature disturbances are frequent, causing the clerodendrum to turn yellow and dry out or, conversely, rot.

Among flower pests, the most active are aphids, spider mites and scale insects. Aphids do not appear on their own: they are brought with other plants or on clothing. The parasite sucks out the sap and kills the plant. Leaves infected with aphids begin to curl.

They fight aphids using laundry soap: rub the bar on a grater and add it to water 1:1. This concentrated solution is diluted again, poured into a spray bottle and sprayed with clerodendrum. Large leaves can be wiped by hand.

Spider mites are greenish-brown insects with a round, bristly body. They hide at the bottom of the leaves and are difficult to see. But their masonry is noticeable from inside the leaves. A soap solution and an infusion of onion and garlic peels help get rid of them.

Onion feathers are boiled in water and diluted with water one to one, the plant is sprayed with this solution. Similar actions with garlic. It is not recommended to use a solution of hot pepper, since it can burn the tender shoots of clerodendrum.

If the mite population is too high, you will have to resort to chemicals. “Fitoferm”, “Karbofos” are the best chemicals. The soil must be replaced and the vessel filled with boiling water. 2 ml of karbofos are diluted in a liter of water.

Greens are treated by spraying from a spray bottle. The treated flower is covered with polyethylene for 3 hours. The frames and window sill, that is, the place where the flower lived, are treated with a solution of karbofos.

Scale insects - insects with a translucent body in the form of a plate - are capable of eating an adult plant a meter long in a couple of weeks. It is difficult to fight scale insects; it is better to use the chemical agent “Aktellik”. 2 ml are dissolved in a liter of water and immediately treated: all insects are collected by hand and thrown away. Then the entire plant is watered heavily with the solution, the remainder is added to the substrate.

Important! If the plant has managed to lose 2/3 of its foliage, its death is inevitable.

Parasite attack

Chamelacium - home care and flowering

Pests are frequent guests on the plant. The most common among them:

One of the pests is the spider mite.

whitefly Leaves behind a white coating. The foliage and flowers dry out from it. The plant is treated with insecticides, and the affected parts are removed by insects;
spider mite It's difficult to see him. Cobwebs in the internodes and limp leaves indicate its appearance. Minor damage can be repaired using laundry soap. Insecticides will help with large levels of damage. To avoid such situations, you need to spray the leaves with water every day;
scale insect. It can be found on stems and leaves. It protects eggs and itself with a shell, so it is very difficult to resist. To do this, first, parasites are collected by hand, and then the flower is treated with an insecticide;
aphids are the most popular parasite. It causes the plant to wither by sucking the juices out of it. The entire plant is treated with insecticides, and the affected areas are removed.

Important! Whiteflies, aphids and spider mites are the most important enemies. If corresponding signs are detected, it is necessary to urgently treat the soil with an insecticide. If the degree of damage to the plant is high enough, then it is better to carry out the procedure several times. After spraying, it is recommended to remove the plant from direct sunlight and cover it with a cloth. Clerodendrum can also be placed in a greenhouse for several days.

Why doesn't it bloom

Sometimes clerodendrum does not bloom. The reasons mainly come down to improper care. Maybe:

The flower was disturbed during dormancy - kept warm or in a draft, the roots were watered too much. If the sleeping conditions are disturbed, the clerodendrum will not bloom in the spring.
The liana has not been replanted for a long time. If the plant has been in one place for more than 5 years, it may wither.
The soil has exhausted its resource and there are no nutrients left in it. It is necessary to completely replace the soil and fertilize it.
Clerodendrum was not fed. Additives are needed once every two weeks, organic and mineral fertilizers are alternated. Potassium and fluoride are definitely needed. Nitrogen is given only at the very beginning of flowering. Feeding in the fall is reduced and not carried out until February.
The plant, on the contrary, was overfed, and it does not want to bloom.
The soil composition is too alkaline or too acidic.
The pot is too huge, and the clerodendrum takes root, gaining mass.
The shrub has just been transplanted and is feeling stressed.
The reason is simple - drought. If a plant is thirsty, it will not bloom.
The flower is attacked by pests and slowly dies.

In all these cases, clerodendrum will not bloom. In September it goes into retirement and stops flowering in winter.

In ancient times, clerodendrum was planted in honor of the goddess of love Aphrodite, and temples and statues were decorated with flowers. Nowadays it is valued no less, because it is very beautiful and already has more than 300 varieties.
