Amazing common oleander flower: care and cultivation at home and in open ground

Common oleander is the only species representing the Kutrov family. This is an evergreen shrub, which has been valued since ancient times for the beauty of its delicate inflorescences. Wild specimens can be found in subtropical areas - in northern Africa and southern China, Transcaucasia and Portugal. Cultivated varieties are grown as indoor flowers and are also widely used in landscape design.

Oleander indoor flower

Oleander nerium oleander is an evergreen perennial shrub with a magnificent appearance. He is a representative of the Kurtov family. The Latin name is “nerion”, translated as “wet”. In warm regions, oleander, due to its variety of shapes and colors, has become a popular ornamental plant for landscape design.

Oleander in nature

There are three main types of oleander. Common oleander is most often cultivated at home. A beautiful flower perfectly decorates your home interior. The tall plant can reach two meters in height, taking on a tree-like form. The growth of indoor oleander should be regulated by pruning.

Oleander is credited with mystical properties to cleanse the energy of the home, get rid of bad habits and promote career success. The fact that the plant cleans the indoor air from harmful impurities is a proven scientific fact.

No one knows for sure whether oleander is highly poisonous, dangerous or not. It is known that the poison is contained in the roots, flowers, and leaves. It is advisable to wash your hands thoroughly after caring for the bush and wear gloves when pruning. These measures are sufficient for protection.

Indoor oleander

Only by eating parts of the oleander plant can symptoms of real poisoning appear. Therefore, the plant is not suitable for rooms where children and pets live.

The leaves of the bush serve as raw materials for the manufacture of medicines for diseases of the cardiovascular system. Creams and ointments for skin diseases are produced from plant extracts.

Important! Due to its strong aroma, the flowering plant should not be kept in the bedroom. This can cause poor sleep and headaches.

pros

1. Exceptional decorativeness
2. Long flowering
3. Pleasant aroma of flowers
4. Relatively simple and easy to maintain

Minuses

A properly formed flowering oleander bush looks amazing. But you have to pay for everything. And having such exceptional beauty, oleander has 2 significant drawbacks:

1. lack of winter hardiness, which makes it impossible to grow it in open ground almost throughout the entire territory of Russia,
2. the toxicity of literally all parts of the oleander, the substance causes disturbances in the functioning of the gastrointestinal tract and heart.

Oleander comes from the subtropics, in Russia it is extremely winter-hardy, it hardly survives even mild southern winters, and can withstand at least minus 5-10 ° C. In case of prolonged frosts of -15 °C and freezing soil, the plant will die.

Therefore, oleander is grown in winter gardens and greenhouses, indoors, or as a tub crop, placed in the garden in the summer and brought indoors in the winter.

Precautions

1. Do not grow oleander if you have children or pets.
2. If oleander blooms in a small room, its smell can cause headaches.
3. Flowering can cause allergies.

Oleander contains potent toxins, so be careful when handling it. Wear gloves when transplanting and rooting. And if there are children and pets in the house, protect them from this plant.

If oleander juice gets on the mucous membrane, you should immediately wash yourself well or rinse your mouth with clean water.

Features of the transplant

Oleander is known among lovers of indoor flowers precisely because of its lush and beautiful inflorescence, as well as its pleasant aroma. For optimal growth and a longer flowering period, replanting should be done regularly during the spring months.

When removing a plant from a pot, you must carefully examine the roots for pests and damaged roots. When replanting, not only roots with signs of disease are removed, but also some healthy roots.

Limiting the growth of the root system promotes brighter flowering and the growth of a lush crown. It is important for the florist to carry out all work wearing gloves and a mask, because the sap of the plant has a pronounced irritant effect.

Origin and appearance

The entire zone of subtropical climate from Portugal to China is considered the homeland of the evergreen shrub. As an ornamental shrub, oleander is very popular in Mediterranean countries, Algeria and southeastern Asia. This sun-loving plant with a euphonious name and fragrant flowers is loved by many gardeners.

Perennial oleander is widespread on the Black Sea coast. In open ground under favorable subtropical climate conditions, it can grow as a tree up to 4 m in height. Sometimes the bushes form entire thickets that exude an amazing aroma.

Bloom

Oleander loves well-lit and ventilated areas. In the shade, the bush begins to hurt and even refuses to bloom.

The plant has beautiful flowers with five petals, painted in delicate white, orange, and pink colors. They are arranged singly or collected in inflorescences and are formed throughout the summer. They are famous for their pleasant strong aroma. The flowers are simple and double. The leaves are narrow, smooth, green or variegated with a distinct middle.

The best varieties

The following types of oleander are currently known and well studied:

• Asian fragrant oleander no more than 50 cm high with pink single flowers;
• large Indian oleander, growing in the tropics of India and China;
• common oleander, cultivated at home and suitable for growing in spacious rooms.

Planting oleander in a pot

To grow oleander, you need to take care of suitable soil and flower pots of a certain size.

Soil for oleander

The soil for the plant is prepared from turf soil, leaf soil, humus, peat, sand in a ratio of 2:1:1:1:1. You can also use slightly acidic garden soil or commercial flower soil. It is important to ensure good drainage.

The soil

Oleander is not very sensitive to fluctuations in the PH environment. Flower growers recommend using loamy soil. For replanting, a mixture of turf (2 parts), leaf soil (1 part), peat (1 part) and coarse river sand (1 part) is suitable. You can add some horn shavings.

Good garden soil with added sand is often used.

Pot size

The plant grows quickly, so the container for seedlings should be spacious, at least 6-7 liters. Every two years, the oleander is transplanted into a larger container. Based on the condition of the root system, you can determine whether the plant needs a new pot.

Planting in pots

The container volume for an adult plant reaches 40 liters.

Possible consequences of negligence

According to doctors, even one leaf of the plant can lead to tragedy. In Israel, he once almost caused the death of six girls. Expecting the leaves to have a narcotic effect, they chewed a small piece. The girls were found on time and taken to intensive care. They did not know that oleander is a poisonous plant. Treatment for poisoning is symptomatic, but first of all you need to remove toxins from the body.

If any part of the plant is ingested, rapid deterioration of the condition, slowing of the heartbeat, bloody diarrhea, loss of consciousness, and cessation of breathing are observed. But the beauty of its flowers is so attractive that no one will refuse to have such a plant at home. The exception is if children, kittens or puppies live in the same territory. They are all too curious.

Oleander care

Optimal conditions for growing oleander

Before purchasing an oleander for a home greenhouse, you should evaluate whether the room conditions are suitable for such a difficult plant.

1. Bright room. Oleander is a resident of the subtropics, where the duration of a sunny day is at least 10 hours. It is better if the plants are installed near an eastern or south-eastern window. You need to take care of the winter illumination of the plant with special lamps.
2. Large room volume, with mandatory ventilation. The strong aroma of oleander, although pleasant to the senses, can cause severe headaches. For the same reason, the flower is not placed in bedrooms, children's rooms or other rooms where people spend a lot of time. It would be optimal to place a pot of oleander in a spacious, bright hall, winter garden, or office.
3. The room should be warm enough, without drafts. For oleander, the optimal temperature is considered to be no lower than +20 degrees. In a colder room, the plant stops blooming and may lose its leaves. For the winter, the plant enjoys a cool existence, with an air temperature of about +15 degrees.

In summer, it is useful to take a young oleander plant outside. Place it in the garden or on the balcony, in a sunny place. An adult plant is too large and not transportable.

Watering and air humidity

On hot summer days, the oleander should be watered regularly and abundantly. The water that drains into the pan through the drainage holes does not need to be drained. Moreover, on such days there should be water in the pan at all times. The rest of the time, watering the oleander directly depends on the temperature in which it is kept. Usually after the top layer of soil has dried. In the cold season, watering the oleander is significantly reduced. Water approximately 3-4 days after the top layer of soil has dried. But be careful, oleander reacts very painfully to dry soil.

Spraying it in the summer is not necessary, but it won’t hurt either. But in winter, if you were unable to provide the oleander with a cold winter, be sure to spray it. Dry air causes the tips of the oleander leaves to dry out.

Bathing and spraying

If dust does not accumulate on the leaves, it is recommended to bathe the plant once a month. In winter, the air becomes dry, so you need to regularly spray the leaves with a spray bottle.

In summer, shrubs growing outside do not need to be sprayed.

Lighting

Definitely - as much as possible! Oleander is a very light-loving plant. At the same time, it is not even afraid of direct sunlight. Location near south-facing windows is the best solution. Oleander reacts very painfully to lack of lighting. The shoots stretch out, the leaves become faded, or even drop them altogether; there is no talk of flowering. In winter, oleander needs bright light no less than in summer. Artificial lighting is recommended.

Temperature

During flowering, oleander needs quite high temperatures. Not lower than +20 degrees. The optimal range is considered to be from +20 to +27 degrees. But it can be higher. The best place for oleander during this period, which falls in the summer, will be in the fresh air. In a well-lit place, but at the same time protected from heavy rainfall. It will feel great buried along with a pot near any artificial pond. But no matter where you keep it, the oleander requires, if not constant, then at least a regular flow of fresh air. This is one of the main rules for caring for oleander. In winter, give it a cool place to stay. During this period, the desired temperature is in the range from +8 to +15 degrees. While the plant is small, the desired temperature can be obtained on a windowsill or insulated loggia (balcony).

During the flowering period

During flowering, oleander needs a temperature of at least 20 °C. An outdoor location protected from the elements will be best. A pot with a plant can be buried near an artificial pond, where the flower will feel extremely comfortable.

Flowering period

If a flowering bush is in a room, you need to ventilate it more often. A strong aroma can affect the well-being of people living in the room. The flowering phase lasts up to five months.

What to do when the oleander has faded?

As they wither, the clusters with double flowers take on an unattractive appearance. In addition, fungi and mites grow faster in them. Dried inflorescences are cut off with garden shears, which are best treated with alcohol or vodka.

Varieties with simple flowers are easier to care for: wilted corollas fall off on their own.

There is no need to rush and cut off the peduncle; new buds may appear on it.

Vegetative shoots growing under flower buds should be removed - they slow down the growth and development of the flower.

Rest period

For the winter, the oleander can be moved indoors. If it is not possible to install the tub away from heat sources, you will have to organize additional humidification. You can place an aquarium or a container of water nearby.

Without good lighting (at least 10 hours a day), the plant may lose its leaves; flowering next year will be sparse.

Oleander pruning and crown formation

To ensure that the branches do not stretch and the flowering is abundant and long, it is important to form the crown correctly.

Sanitary pruning should be carried out annually in spring or autumn. A radical rejuvenation procedure is carried out every 3-4 years.

Spring pruning is carried out when buds have not yet appeared on the stems. The branches are shortened by half (and sometimes by 2/3), which stimulates the development of new shoots. Young shoots produce larger inflorescences.

When grown in the ground, overgrown bushes are pruned to the stump. This procedure is carried out in late autumn or early spring. All shoots are removed, leaving 15-18 cm stumps. Large cuts must be treated with garden putty.

This pruning method is not suitable for young plants, since their root system is not formed. Old and weak plants should be pruned with caution.

By properly shaping a young plant, you can get a slender flowering tree.

Care should be taken when working. You need to wear gloves and avoid getting the juice in your eyes.

Crown formation

In order for the oleander to grow as an attractive and flowering bush, it is important to correctly form its crown. First of all, do not forget to turn the flower in different directions towards the light, it will develop evenly. In addition, prune the oleander annually, otherwise the plant will produce few buds. To do this, after flowering, shorten the shoots of the flower by half or a third of the length. And also cut out damaged branches and those that grow deep into the plant.

Top dressing

Oleander spends a lot of energy on the formation of buds, so it needs regular feeding. From the beginning of spring to the end of summer, apply fertilizers 2-4 times a month, alternating organic and mineral formulations. Feed the flower on cloudy days or early in the morning, and only after watering. Otherwise, the compounds will burn the roots of the plant.

Features of care in winter and summer

In order for the plant to rest and gain strength for long, lush flowering, in winter it is advisable for the oleander to find a bright place with a temperature of +10-12 °C

• In summer, oleander feels comfortable at a temperature of 20–30 °C.
• In summer I take the oleander outside because it needs fresh air.
• In winter, I try to provide it with a cool hibernation - 8–15 °C.
• I water much less frequently during the dormant period.

For this, the oleander thanks me with generous and abundant flowering in the summer.

Transfer

With proper care, oleander grows quickly, so replanting is indispensable. For young plants, carry out this event every spring; replant adult specimens every 2-3 years. And also an emergency transplant is needed for those flowers whose roots have rotted or begun to protrude from the pot.

Carry out the procedure this way:

1. Place a layer of broken bricks, pebbles or expanded clay at the bottom of the new container. Sprinkle the drainage with a centimeter of substrate. More details about soil for oleander are written in the section “Transplanting into soil”.
2. Carefully remove the flower from the old pot. To make this easier, water the plant a few hours before the procedure.
3. Trim any roots that are too protruding or damaged, and sprinkle the cut areas with crushed coal.
4. Place the flower in a new pot, fill in the voids and lightly compact the soil. Make sure that the root collar is flush with the ground.
5. Water the plant and return it to its normal place.

Provide proper care for the oleander and create comfortable conditions for it, and the plant will definitely thank you with rapid growth and numerous buds. To do this, follow the growing recommendations and carry out all necessary agrotechnical measures.

Watering

Oleander is a moisture-loving plant, so it needs regular and abundant watering. From spring to autumn, moisten the soil as soon as its top layer dries. Moreover, in the heat of summer, do not drain excess water from the pan. In winter, reduce watering, moisten the flower two days after the top layer of soil dries. At any time of the year, use only soft and filtered water whose temperature is slightly above room temperature. And also be sure to leave it for 24 hours before watering.

In summer, oleander does not need spraying. But it is advisable at this time to place the pot on a tray with wet expanded clay or pebbles. In winter, when the air is heavily dried by heating devices, spray the foliage occasionally, otherwise its tips will begin to dry out.

Reproduction

Oleander propagation occurs in several ways:

• By cuttings. It is recommended to carry out this procedure in spring. For cuttings, freshly cut shoots 12-15 cm long are used. The cut should be greased with powdered charcoal and the cutting should be planted in a mixture of charcoal and coarse sand. The cutting needs good lighting and temperature control, just like an adult plant. Excessive watering should be avoided to prevent the shoots from rotting. After two months, the cuttings with sprouted roots can be transplanted into a soil mixture with a composition suitable for oleander.
• Air layering. The branch is cut, a fragment of bark is removed and placed in water or wet sand. When the roots are formed, the shoot is cut off from the mother plant and planted in a standard soil mixture.
• Seeds. First, they are soaked in a solution of potassium permanganate, then in a solution of Zircon. The composition of the soil mixture where the seeds are sown is the same as for adult plants. But the air should be much warmer - 30-35 degrees Celsius. The substrate is placed in a container with a drainage hole, slightly moistened, and seeds are sown into it. They sprout in a week and a half. It is necessary to monitor the light regime and use artificial lighting. When young plants have several leaves, they can be planted in single pots.

Preparing for sowing

To begin, prepare a container or pot with drainage holes and fill the container with an all-purpose seedling mixture. If you want to create a substrate for plants yourself, then mix the following components in equal parts:

• peat;
• turf soil;
• perlite

In addition, it is important to pre-prepare the seed. To do this, soak the oleander seeds in potassium permanganate or a fungicide solution for 30 minutes. And then keep them in any growth stimulant, such as Zircon or Heteroauxin. This way you will significantly increase its germination rate.

After preparation, distribute the seeds evenly over the surface of the substrate and press them slightly into the soil. Spray the planting with warm water from a spray bottle and cover with plastic or glass. Place the greenhouse in a place with bright but diffused light, out of direct sunlight.

How to care for planting

In order for the seeds to germinate, it is important to maintain the temperature in the greenhouse within +25 °C. You should not allow it to rise to +35 °C, otherwise the plants will “burn.” And you also need to make sure that the temperature in the greenhouse does not drop below +22 °C, as this will lead to rotting of the seeds.

Otherwise, caring for crops consists of daily ventilation of the greenhouse, as well as periodic moistening of the soil. It is also important to provide the plants with enough light. Therefore, if the weather is cloudy outside, it is advisable to arrange additional illumination with a phytolamp.

Under such conditions, seeds will germinate in 30 to 90 days. When the seedlings emerge, begin to gradually accustom them to normal conditions. To do this, remove the cover first for 30 minutes, then for an hour, and so on. When the seedlings have two pairs of true leaves, plant them in individual pots.

Rooting in water

This method of propagating oleander should be used if the temperature in the room where you will root the cuttings does not rise above +30 degrees. In this case, place the workpieces in containers with water with the addition of a root formation stimulator. Make sure that the temperature of the solution fluctuates between +20...+27 degrees. And also add water to the container as it evaporates.

Keep the cuttings in an area with bright but indirect light, away from direct sunlight. Rooting the cuttings in water will take about 35-40 days, during which time they should grow roots 3 cm long. As soon as this happens, plant the seedlings in individual pots.

Dividing the bush

This method is used when transplanting overgrown shrubs. The plant is removed from the tub and the roots are carefully removed from the ground. If the root system is healthy and there are many growth points on the shoots, the bush is divided into 2-4 parts using a sharp knife. All wounds should be sprinkled with ash or activated carbon powder. After drying the rhizome in air, it is placed in a planting container of a suitable size.

Crown formation

How to prune oleander?

The flower needs constant pruning due to its rapid growth rate. Not just cosmetic, but careful pruning is useful for him.

IMPORTANT!

Flowers bloom exclusively on young shoots of the current year.

When flowering ends, you can trim the oleander and form a crown. The shoots are shortened by half to allow new ones to grow. The plant calmly tolerates the pruning procedure.

Watering

The flower is watered abundantly almost all the time, except in winter.

In summer, it is recommended to pour water into the pan to retain moisture longer. On cloudy days and when it is cool, make sure that the tray is dry.

It is advisable to water with settled water so that it is soft and warm - a few degrees above room temperature.

Reproduction

Oleander can be propagated either by cuttings or by air layering. The cuttings are rooted after being pre-treated with charcoal and dried. The near-root surface is sprinkled with sand to prevent the process of rotting of the stem.

Venation

Air layering of oleander is rooted using wet sand or a glass tube filled with water. When the roots appear, they are cut off from the mother plant and transplanted into a separate container.

Growing oleander from seeds at home

The flower pods contain seeds that can be used for planting.

REFERENCE

The seeding soil is prepared from a favorable substrate - turf soil and peat. The seeds need to be pressed to the ground, pressing lightly. Do not cover it with soil under any circumstances - the seeds need the rays of the sun. Sprouts appear in the second month after sowing!

Landing

To plant oleander, prepare heavy loamy soil. Make the soil composition in equal parts, using peat, sand, humus and turf soil. The mixture can be replaced with a purchased one by adding sand to it.

Transfer

Young oleanders need to be replanted annually, and adults every 3 years. Transplantation is carried out after the roots entwine the earthen ball. Favorable time - late spring - early summer. It is advisable to shorten old roots by treating the cut areas with charcoal.

Outdoor care

Oleander grows beautifully in the garden, blooming magnificently with gorgeous flowers in yellow, white, pink, and red colors.

The plant grows quickly on the sunny side, but is absolutely intolerant to the shady side.

Minimal care required:

• The shrub tolerates dry periods well if it is well watered. You also can’t overdo it, otherwise the leaves will turn yellow;
• In spring it is advisable to feed with complex fertilizer;
• Periodic shaping of the crown by pruning will help give the plant the desired shape, and it is also useful for getting rid of damaged branches.

Growing from seeds in open ground

Remember that oleander seeds cannot remain viable for a long time. It is better to sow them immediately after ripening so that sprouts appear as soon as possible. Before sowing, soak the seeds in a weak solution of potassium permanganate. Sow in moist soil, sprinkled with a thin layer of soil. The soil mixture is prepared with the addition of peat and sand.

How to cover an oleander for the winter?

It is most convenient to cover the trimmed plant. Use film as insulation. The bush can be covered completely, and the trunk of the tree is wrapped.

Diseases and pests

Oleander is hardy and well adaptable to almost any conditions. The pests that plague him include:

• scale insect;
• mealyworm;
• spider mite

To combat them, insecticides or traditional methods are used.

Shchitovka

When the first signs appear (sticky coating, deformation of leaves) or the parasites themselves, it is necessary to wash the foliage with warm water and laundry soap, then dry the bush in the open air.

Spider mite

If yellowish spots and thin cobwebs appear on the leaf blades, a mite has settled on the plant. Traditional methods of struggle are ineffective; it is better to use special drugs.

Mealybugs

A favorable environment for these pests is warmth and moisture. Oleander grows in such conditions, so it is better to prevent infection. It is necessary to remove dried flowers and stems in a timely manner and regularly inspect the flower.

What to do if the oleander does not bloom?

If the plant is not pruned by removing the tips of old shoots, it will not bloom, because flowers are formed only on young shoots .

Form the crown more often for lush flowering of the shrub.

Other reasons may be lack of moisture or nutrients. Water the plant in the required amount and do not forget to feed it with fertilizers, especially if the soil is infertile.

Why did the oleander leaves turn faded?

Most likely, the oleander does not have enough light. The shadow is extremely destructive for it; photosynthesis processes are disrupted. If it is not possible to replant, try to increase the access of sunlight to the shrub.

What to do if the oleander loses its leaves?

This is a signal that the plant is in a draft or does not have enough light. Increase the access of light to it and try to protect it from drafts. The amount of light must be increased gradually so as not to injure the flower.

What should you be afraid of?

Even the most dangerous plants can only have certain parts that are toxic. But that's not what oleander is like. Whether it is poisonous or not is better not to check in practice. All parts of the plant can cause poisoning. Even when dried, they retain toxins. Leaves and stems, fragrant flowers and roots, but especially dangerous is the fresh and dried juice that is released when cut. If it gets into the eyes, it leads to blindness, and vision cannot be restored. But the most harm will happen if the juice gets into the digestive tract. Even a tiny amount leads to the fact that a person can die without quality and timely help. This is the handsome oleander. Poisonous or not, now there is no doubt. And for the safety of curious kids, it is better to “evict” the plant to one of your friends.

Demanding flower: what do you need to know?

For successful cultivation, these features should be taken into account.

1. It blooms from June to October.
2. He needs a lot of sunlight.
3. A drop in temperature to +17 will be perceived as stress in the summer and spring. In winter, indoor oleanders can withstand temperatures down to +8 without shelter, and garden oleanders up to -10, but with proper preparation.
4. Watering should be frequent and plentiful. The plant loves abundant watering, as well as humidity, and therefore in areas it is often planted next to ponds.
5. There are no special requirements for air humidity, but it has been noted that oleander reacts negatively to a decrease in air humidity. In nature, it is often found on river banks.
6. Fertilizers should be applied 2-4 times a month in spring and summer. Mineral fertilizers are used for flowering plants.
7. It is an evergreen plant, but with negative changes in the environment it can lose its leaves. In this case, they stop watering the flower, if possible, transfer it to a balcony or loggia to maintain a natural reaction to seasonal environmental changes, and wait for the end of the growing season dormancy period.
8. The period of vegetative rest lasts from November to February. In order to avoid the risk of its spontaneous onset and death of the flower, it is necessary to observe the timing of germination of seedlings from seeds or cuttings (it is carried out in spring or autumn).
9. Pruning and shaping are carried out immediately after flowering is completed. The bush of this perennial grows quickly. In the first year it looks elegant thanks to the splendor of the foliage and the appearance of the ovary and flowering. If pruning and shaping are not carried out, it can grow up to 2 meters very quickly. Formation is carried out using protective gardening gloves. If juice gets into your eyes or mucous membranes, rinse them with plenty of water. After the procedures, it is advisable to wash your hands with soap. It is recommended to regularly prune the bush, however, this must be done while protecting your eyes and hands.
10. The plant is replanted in the spring.
11. The following soil mixture is most suitable for cultivation: peat, sand, chernozem, with an acidity of 5.5 to 7.8.
12. Propagated by seeds and cuttings, layering, shoots, grafting.
13. The plant should be protected from pests such as mealybugs, scale insects, spider mites, aphids, thrips, and oleander cancer.

Neutral soil is more suitable for growing oleander

Important! Considering such nuances, there is no need to fear that the flower will wither suddenly. It will take root in the garden or will decorate a window sill, balcony, or room for many years in a row.

Temperature

Oleander, the photo of which is given in the material, is a heat-loving plant, but the flower does not tolerate heat well. Therefore, from spring to autumn, maintain the room temperature at +20...+25 °C. If you wish, you can take the pot to the balcony or garden. In winter, it is advisable to move the flower to a cooler room, where the temperature fluctuates between + 8 ... + 15 ° C, but it is important that the oleander receives enough light, otherwise it will shed its leaves.

At any time of the year, you need to provide the flower with an influx of fresh air. So don't forget to ventilate the room regularly. But keep in mind that oleander does not tolerate drafts and sudden temperature changes. So during the procedure, take the pot to another room.
