Clivia is an evergreen herbaceous perennial plant of the amaryllis family. The homeland of the flower is the subtropics of South Africa. The flower feels great in indoor conditions, is not whimsical to care and is rarely affected by pests and diseases.
Florists appreciate the plant for its lush flowering and bright buds, which not only transform everything around, but also give a fascinating aroma. There are practically no difficulties with growing: only a lack of elementary knowledge of the biological characteristics of a plant and a violation of elementary conditions of detention can provoke diseases and the death of a flower.
The name of the genus Clivia was given by the botanist John Lindley, who named it after Duchess Charlotte Clive (Queen Victoria's governess). She was famous for her passion for floriculture.
Reference. The clivia genus differs from different representatives of the amaryllis family by the absence of a bulb. Instead, the flower has powerful and fleshy leaves at the base, which grow like a pigtail and form a strong pseudostem.
Under the ground, clivia develops a white and thick fleshy rhizome to which thickened leaf bases are attached. inflorescence of 20-60 pieces per peduncle. Flowering begins in February - March and lasts for a month. When nature is still just preparing for the awakening process, clivia blooms and pleases the owners.

Diseases with photos and treatment methods
Why doesn't it bloom at home?
Transplanting into an oversized pot
At the same time, Clivia begins to build up vegetative mass, filling the space in the soil with the root system. Leafy shoots are also actively developing.
Attention! Clivia blooms only when the entire pot is completely occupied by roots.
Solution: when transplanting a plant, choose a pot 3 cm wider than the previous one.
Every florist should remember that plants over 10 years old cannot be transplanted (when is it necessary to transplant clivia and how often?).
Lack of nutrients
Clivia responds very well to feeding. And lack of nutrients has a detrimental effect on flowering.
Solution: You need to start feeding the flower in the summer already in the first year of life. The flower should be fed once every two weeks, and alternate between organic and mineral fertilizing.
It is important to choose organic fertilizers based on vermicompostas they give the maximum effect.
It can be Ideal, Giant, Breadwinner. For watering, take 1 tablespoon of fertilizer and dilute in 2 liters of water.
Mineral complexes such as Ammophos, Kemira, Nitrofoska are diluted in warm water in a ratio of 2 g of fertilizer per 1 liter. Since September, the flower is stopped fertilizing. The next top dressing can be carried out after the clivia has released the peduncle arrow.
Excess nitrogenous fertilizers
When choosing fertilizers, you need to carefully read the composition. Nitrogen-based fertilizers can delay the formation and emergence of peduncles.
Solution: If you want abundant flowering, then you should give preference to complexes with a high potassium content.
Uncomfortable air temperature
Air temperature too high or too low.
Solution: The optimum temperature for clivium is +20 degrees. Hibernates at +18 degrees.
Causes of leaf drying
Excess moisture, stagnant water
Solution: Observe the watering regime. In case of excessive moisture, you need to check the roots of the flower. The diseased roots are removed. Treat the sections with crushed charcoal for disinfection. The plant is transplanted into a pot with new soil and smaller than the previous one. Maintain moderate watering.
What causes the plant to turn yellow?
Solution: biological aging of some leaves and the generation of other leaves is a natural process of nature. In such cases, nothing needs to be done.
If the flower stands on a windowsill in direct sunlight, then burns will remain on the foliage.
Decision: it is necessary to provide diffused light to the flower.
Ripening of seeds
During pollination and ripening of plant seeds, there is a redistribution of nutrients from the leaves to the flower fruit (for how to propagate clivia by seeds, shoots and part of the rhizome, read our material). At the same time, the leaves turn yellow.
Solution: remove the peduncle after flowering stops.
Lack of fertilizer
Actions: apply fertilizers once every 2 weeks.
What if the peduncle does not grow?
- cold content during budding;
- content without a dormant period;
- weak watering at the beginning of active growth;
- too warm wintering.
- After the appearance of the arrow of the peduncle, the pot is transferred to the east window and the air temperature is optimized from 20 ° C to 25 ° C.
- Watering the plant with warm water, the temperature of which does not exceed 40 ° C.
- Provide peace in the autumn-winter period (at least 2 months) until the peduncle appears.
Important! The older the clivia, the longer it will take to rest.
- During the formation of buds, the volume of watering is increased.
- Resting temperature 12 ° C to 15 ° C.
How to create an enabling environment?
To avoid diseases and achieve regular flowering of clivia, the following conditions must be observed:
- Providing a dormant period.
Young plants rest for two months from October to November. Adults and large specimens require longer rest. In September, watering is reduced to 1 time per month. Placed in a cool place with an ambient temperature of 14 degrees. After the flower arrow appears and grows up to 10-15 cm, the plant is placed in a warm place. Watering becomes regular. Fertilizers are applied as needed.
- Do not disturb the plant.
During the period of bud setting and flowering itself, you cannot rearrange the flower from place to place. If the need arose, then you need to maintain the direction of growth of the flower, otherwise the plant may shed its leaves. Clivia blooms from February. The flowering period is 3-4 weeks.
Shield or shield aphid
Insect of the worm family, covered with a wax shield. Scale larvae are mobile. Adults stick to the plant and remain motionless. This makes it easy to spot. Outwardly, they resemble wax droplets or growths.
Attention! The scale insects suck out the sap of the plant and secrete a sticky liquid that clogs the pores, making it difficult for the plant to breathe. Leaves die.
- The provoking factor is dry air and lack of light, therefore it is necessary to provide additional light and spraying.
- Remove dead plant parts.
- Wash off remaining pests from live shoots using a soft brush and a solution of laundry soap.
To get rid of the scale insects that are hidden in the leaf axils, you need to treat the plant with insecticides. For instance: Aktara, Aktellik, Fitoverm, Arrivo.
It becomes more active in winter and spring. In conditions of dry and warm air, he feels at ease and develops. The sucking insect pierces the walls of the leaf blade and takes away the nutrients necessary for the plant. A small yellow spot remains at the puncture site. Leaves lose their turgor, fade. The tick leaves a cobweb that can be seen in the light.
Actions: to increase the humidity, the plant is sprayed, to get rid of the insect, it is treated with a solution of laundry soap.
With a strong spread of spider mites, they are treated with acaricides - anti-tick drugs. For instance: Akarin, Agrovertin, Inta-vir, Vertimek.
Important! The mealybug is a sucking insect; young shoots of the plant are a favorite place.
Colonies of mealybugs on the leaves look like dusting with flour or like small pieces of cotton wool. The reason for the appearance of a mealybug on a plant may be improper care. (how to properly organize the care of clivia at home?).
Action: When you first find a mealybug, you can simply remove it with a damp swab. But if it has already multiplied and formed colonies, then it is necessary to spray the clivia with an insecticide weekly until it recovers. In case of severe infection, it is better to change the soil in the pot.
Outwardly it looks like a small moth. You can observe it in the summer on the lower part of the leaf blades. It affects young shoots, which are easier for her to pierce. It feeds on the nutritious sap of the plant. Excess juice is secreted outside, forming "honeydew". As a result of the vital activity of aphids, the leaves of the plant twist and deform.
- Trim the most affected clivia leaves.
- Treat the flower with an insecticidal preparation.
- Quarantine the plant from other flowers to avoid contamination of other flowers.
Compliance with the simple rules for caring for clivia guarantees its timely and abundant flowering. Regular inspection of the flower will help to detect and eliminate the cause of the infection in time. Care and maintenance always give good results.
