Clerodendrum: Plant Care

Clodendrum (lat.Clerodéndrum), which is a deciduous shrub, a small tree with unusual flowers with bright red stamens, has gained considerable popularity among gardeners. The plant is considered relatively unpretentious when caring at home, the main thing is to adhere to the rules of watering and keeping the plant. In nature, it is found mainly in tropical and subtropical regions of the planet.

Clerodendrum flower

This perennial sprawling shrub, lignified liana, belongs to the verbena family. Clerodéndrum is found in many regions of the world - the natural habitat of the plant includes Australia, America, Africa and Asia. The flower is found in China, Korea, Indochina, India, Japan and the Philippines. The plant is thermophilic, because most species are concentrated in the tropics, subtropics, and only a few can be found in the temperate climate zone. In total, about 400 species are known.

Klerodendrum Types

The name of the shrub translates as "tree of fate", although it is often called "volcamery" or "innocent love." For growing, the plant needs a protected sunny area with well-drained soil. The plant propagates:

  1. separation of rooted lateral shoots;
  2. sowing seeds in the spring.

Flowers in most cases resemble the shape of a butterfly, but in some shrubs, inflorescences resemble bouquets of an unusual shape. Flowers and leaves with a rough "quilted" surface exude aroma in most volcameras. Famous species include:

  • Mrs. Thompson's Clerodendrum;
  • Wallich;
  • Fragrant;
  • Schmidt;
  • inerme;
  • bunge;
  • Philippine;
  • Ugandan
  • special zoom.

Mrs. Thompson's Clerodendrum (Thompson)

Clerodendrum thomsoniae is one of the most common species in indoor floriculture, which is a ligniferous deciduous vine with smooth, thin shoots. Large dense leaves of dark green color have distinctly protruding veins, solid edges and an oblong-ovate pointed shape - the length reaches 12 cm. On the upper side of the plate (leaf) you can see irregular spots of more or less light shades.

From the sinuses of the plant grow loose racemose inflorescences, consisting of white swollen flowers with a red corolla. At home, Thompson volkameria propagates by means of cuttings, and grows very quickly - subject to a competent attitude and compliance with all care rules. Clerodendrum thomsoniae blooms, usually from March to June.

Philippine

Clerodendrum philippinum is a shrub species characterized by a strong and pleasant jasmine-vanilla aroma that begins to intensify in the evening. This representative of the genus is an infrequent guest in the apartments of Russians, although he is relatively capricious in leaving, and begins to bloom already in the 2nd year of life - pinkish-white inflorescences up to 20 cm across indicate this. They consist of pink flowers, reaching a diameter of 2-3 cm. The tenderness and beauty of the inflorescences are emphasized by the wide leaves of a dark green hue.

Ugandan

Clerodendrum ugandense is a fast-growing and evergreen vine up to 2 meters long. The leaves are broad-lanceolate, dark green in color, and the flowers are collected in loose small-flowered inflorescences - with their blue filamentous stamens they resemble butterflies with antennae. The lateral and upper petals are blue, and the lower petal (barely noticeable) is purple or lilac blue. This "tree of fate" is ideal for gardeners in that it can be shaped like a tree or a bush.

Clerodendrum Wallich

This species is often referred to as Prospero's Clodendrum, or “Cleopatra's tears,” “bridal veil,” or “veil of the bride.” Its distinctive feature is the abundant flowering of snow-white inflorescences, which consist of an exquisite form of flowers. The plant is an elegant bush that can fit on the narrowest window sill. It has tetrahedral shoots and dark green lanceolate leaves 5-8 cm long with a wavy edge. The species is considered the most difficult to grow indoors, it requires high humidity and special daylight hours.

Fragrant

Clerodendrum fragrans is an evergreen shrub up to 2 meters high. The shoots are lowered, the same lowered leaves grow up to 20 cm long on them. The leaves are characterized by a lowered wide egg shape and deep teeth along the edges. Simple or double flowers, white with a pink tint outside - are able to thin the aroma with notes of citrus and violet. They are collected in thick apical shields, the diameter of which reaches 8 cm. The fragrant clerodendrum blooms with virtually no stopping.

Variety specosum

Clerodendrum speciosum (Speciosum) or "beautiful" has gained considerable popularity. This sprawling bush reaches a height of up to 3 meters, and consists of tetrahedral branched shoots. The plant is evergreen, covered with large leaves with a heart-shaped and short soft villi. They grow on petioles of a reddish hue. With proper care from June to September, you will be pleased with purple inflorescences with a darker purple-red corolla.

Clerodendrum Schmidt

Clerodendrum schmidtii, or "Chain of Glory", is a very spectacular kind of plant with an elongated leaf shape with slightly wavy edges. It blooms with a beautiful waterfall of white flowers, making the impression of falling snow. During flowering, many brushes on drooping peduncles are formed on a small tree or shrub. Flowers exude a sweet, pleasant aroma. Pistiform flower inflorescences can reach a length of one and a half meters or more. Often blooms 2 times in the winter season.

Clerodendrum inerme

Clerodendrum inerme, or “unarmed” - is an evergreen volcamery with long vines that is covered with oval leaves of an emerald hue. The central vein of the latter is characterized by relief. The shrub blooms in white flowers, similar to moths - they are characterized by the presence of long purple stamens. A variety of inerme variegate (Clerodendrum inerme variegata) is considered very interesting, characterized by lighter (lime) spots on the leaves, thanks to which an original marble pattern is created.

Clerodendrum bunge

Clerodendrum bungei is a rare plant that attracts attention with its decorative foliage and stunning flowers. This perennial deciduous shrub reaches 1.5-2 m in height. In the homeland (in China and Vietnam) and in regions with mild, frost-free winters, the bunge grows in a small tree. Otherwise, it successfully develops as a overgrown shrub of an unimaginable diameter - shoots can appear from the soil even at a distance of 2 meters from the parent shrub.

Very decorative inflorescences Clerodendrum bungei, which reach 20 cm in diameter. Caps in the form of small pink-purple flowers appear on the tops of shoots from the beginning of August to the end of September - they have a pleasant perfume smell. Flowering continues for a long time, because a large number of developing buds pushes faded flowers, successfully replacing them.

Caring for Clerodendrum at Home

Having decided to grow brilliant clerodendrum (Clerodendrum splendens) with corymbose or racemose inflorescences, bunge, Wallich or another type of plant, read the rules for caring for it. Shrubs can be given a different shape by pruning and pinching, for example, ampelous, bushy. It’s not difficult to care for volcamery, as she is hardy, unpretentious and at the same time fabulously aesthetic and fragrant. Particular attention should be paid to temperature conditions, lighting, watering and soil moisture, top dressing, pruning, transplanting and controlling pests and diseases.

Temperature mode

Tropical forest clerodendrum for full flowering and healthy growth requires conditions that are as close as possible to natural conditions. It is preferable to place the plant at home on window sills of windows facing west, east or south, because he needs bright light, but with protection from direct sunlight. In the period from April to November, the optimal air temperature for the Volcamery is from +20 to + 25 ° C.

At too hot times of the day, you need to ventilate the room more often or expose the plant to open air - while remember to protect the flower from drafts. In the winter season, provide the volcamera with a cool content of about + 15 ° C. As for the indicator of humidity in the room, it should be increased. In this regard, you will have to perform nightly spraying the flower with soft water (settled) in the warm season, and in winter - move the pot farther from the radiators.

Lighting

Of no small importance for clerodendrum is lighting. Shrub prefers bright diffused light for 12-14 hours a day. Place the plant on the east / west windowsill or in the back of the south room. Note that he will need a shade at noon. As for the northern window, there will not be enough light near the clerodendrum - you will have to use a phytolamp, because without it you won’t get any flowers.

Watering and soil moisture

Indoor flower needs moderate but regular watering. At one time, a small portion of soft water should be poured into the soil, and at room temperature. Make sure that only the topsoil dries out in summer and spring, and in winter the ground can be allowed to dry by half, but no more. During dormancy, soil hydration is carried out according to the following principle: the cooler the room, the less often water the shrub, but should not completely dry the earthen lump.

Features of plant nutrition

Volkamery fertilizer is required from March until flowering is completed. Perform this procedure three times a month. For this purpose, a solution of a complex mineral plant, which is intended for flowering plants, is poured into the ground. Try to get really high-quality products so that your efforts are not wasted. In autumn and winter, the flower does not need to be fed.

Clodendrum Bloom

Volkameria begins to bloom, depending on the species, from June, and the flowering period occurs in September. In early spring, even on the bare shoots of the Thompson clerodendrum, which is a popular indoor flower (along with the shiny volcamery), one can observe the appearance of white bracts. Raspberry corollas with a diameter of up to 2.5 cm are formed from them. The "beautiful" species blooms from June to September with panicles consisting of purple leaves, and the "fragrant" one almost all year round.

Rest period

Volkameria is a plant with a pronounced dormant period. He comes in the winter, when a tree sheds part of its leaves. At the same time, watering is significantly reduced, but not completely stopped. The earthen lump should not dry completely. The temperature of the content should be no more than + 12 ... +15 ° C. If this mode is not observed at relative rest, then you will not see the flowering of the bush.

Cropping and shaping the crown

When caring for clerodendrum, it is important to produce annual pruning of shrubs at the beginning of a period of active growth. Caring for the Thompson species, in addition to removing weak or dried branches, requires shortening all the shoots by 1/3 of the length - this stimulates abundant flowering, intensive growth and branching of young side shoots. Inflorescences form on the latter. Shrubs are trimmed to form crowns. If you want the plant to grow in a bush, then during spring pruning, greatly shorten the shoots, otherwise you will need to later establish a support for them.

Learn how to crop plants to form a tree. The stamp form is created as follows: all shoots are removed, except for the strongest (one), which is pruned at a height of 50-70 cm, after which all shoots appearing in the apex region are nipped. Due to the branching of the latter, a crown will form over time. If you notice that shoots appear below the crown, then be sure to remove them.

Transfer

The cultivation of volcameria requires periodic replacement of the old soil with a new one. In addition, an overgrown bush requires a pot of larger capacity. When planning to transplant clerodendrum, keep in mind that this is done at the beginning of active growth, but after pruning. For young plants, an annual transplant will be required, and because of the older, it is needed once every 2-3 years. The soil for shrubs should be slightly acidic (pH 5-6) and nutritious. You can use the soil from the store, supplementing it with sand, or make from equal parts:

  • sheet and clay earth;
  • coarse sand;
  • peat.

Before transplanting the shrub, disinfect the new soil for a couple, in the microwave or oven. To solve this problem, follow a few simple steps:

  1. prepare a pot 2 cm in diameter and 2 cm in height larger than the old one;
  2. fill the pot with a drainage layer 3 cm high, transfer the bush from the old flowerpot to a new one, trying not to damage the root coma;
  3. add a new substrate to fill the voids and water the bush;
  4. if the plant needs support, then dig it during the transplant, so that then you do not have to stick it - so there is a big risk of damaging the roots.

Reproduction-

As for reproduction, it is produced by seeds. They are sown in late February or early March - for this a mixture of sand, peat, turf land is used. Then they are placed in a greenhouse and kept in good light, maintaining moderate soil moisture and airing. It takes a long time to wait for the first shoots - 1.5-2 months. When they have four true leaves, they need to be dived into small containers with a diameter of 6 cm one seedling or in a container with a diameter of 11 cm - three seedlings. As soon as they become comfortable and begin to grow, begin to accustom them to the conditions for adult plants.

If you already have a volkamery, then you will not need a seed (generative) method of reproduction. Use the cuttings (vegetative method), the more so cuttings easily root in water, especially in spring or summer. The rooting cuttings will need to be planted in a container with a diameter of 7 cm and grown under a glass hood, not forgetting to keep the substrate moist. Proceed as follows:

  1. As soon as the root system has developed, and the stalk has leaves and shoots, transfer the stalk with the root lump into a large pot with a diameter of 9 cm. In the container, the bush will grow until spring, but without a cap.
  2. In a year from the beginning of rooting, transfer the bush to a pot with a diameter of 11 cm. It should be filled with soil for an adult tree.
  3. For all the time, do not forget to pinch the shoots at least 2 times to stimulate the growth of side branches.

Pests and diseases

Clerodendrum possess excellent immunity and very rarely, with prolonged and improper care, suffer from fungal diseases. Of the insects, the tree is attacked by a spider mite and whiteflies (leave honey dew), which often breed when the air is too dry. At the same time, the spider mite is too small to be seen - it finds its presence with white dots on the underside of the leaf plate and a barely visible cobweb on the leaves. The following describes diseases, pests and methods for eliminating them:

Signs

Possible reasons

Ways to fight

Bush oppressed, languid

Root rot

Remove the volcamera from the container, rinse the roots, and remove the most damaged parts.Then sprinkle the roots with charcoal (crushed) and plant in a new land, not forgetting to regulate watering.

Yellow leaves

Chlorosis

Water and spray with standing and soft water

Leaves rolled inward

Aphid

Remove the most affected leaves, rinse the rest and spray with an insecticide (dilute 1 liter of water with 2 ml of Fitoverm). Re-treat after a couple of weeks.

Plaque on leaves, deformed shoots and leaves

Spider mite or whitefly

Rinse the bush, spray with an insecticide and conduct another treatment after 2 weeks.

Why does clerodendrum not bloom

Often, beginners in the field of floriculture and horticulture try to find out from more experienced comrades why their volcamery does not bloom. The reason is simple, and lies only in the fact that the rules for growing shrubs have been violated. Flowering often does not occur due to improperly organized wintering, which should be cool. As soon as the flowering comes to an end, reduce the frequency of watering and prepare a cooler room for the bush. Watering should be conditional so that the plant does not dry out.

Leaves fall

If you notice that leaf fall began after flowering, then most likely it is a natural autumn process for deciduous plants. Leaves begin to turn yellow and fall throughout the autumn and winter, leaving only bare shoots. True, in spring and summer, the process of leaf fall should not be observed, so you have to revise the rules for caring for wolves and correct your mistakes. Alternatively, change the location of the bush, if it is not the most successful.

The plant turns yellow

If you notice that the leaves began to turn yellow in the summer or spring, the main reason is the lack of moisture in the soil. It is solved simply - water the plant more abundantly or more often, so that water is always present in the pan. Another cause of yellow spots on the leaves is the disease chlorosis. It can be cured by feeding Volcamery with iron-containing drugs. In this case, do not forget about the rules of care.
