Aglaonema, cultivation and care
HOW TO GROW AND CARE FOR OUR PLANTS
L'Aglaonema it includes numerous species native to Southeast Asia, much appreciated and widespread in all our homes not only for the ease of cultivation but also for the beauty of their leaves.
Botanical framework of theAglaonema
Species: see the paragraph on "Main species"
General information about the plant
L'Aglaonema belongs to the family ofAraceae, a very rich family of genres among which we remember: Spathiphyllum spp., Dieffenbachia spp.,Philodendron spp., Anthurium spp.,Caladium spp. etc.
It is a very common plant in our homes not only for its ease of cultivation but also for the beauty of its leaves.
The Aglaonema they are herbaceous perennial plants, originating in Southeast Asia, with a crescitalenta.
They are characterized by leavesvery decorative carried by long gray - green petioles, very thick streaked with white - yellow or silver.
It produces inflorescences aspadice very similar to those of the Calla (they belong to the same family).
In fact, what we call flower, that is the more or less colored part, are actually the bracts, that is to say the modified leaves that wrap the inflorescences and the flowers to protect them and are called SPATA (mostly white or green).
The flower (the inflorescence) is actually that sort of rod that we see in the center of the spathe and is called SPADICE which bears the male flowers in the upper part and the female flowers in the lower part.
THE fruits they are berries.
The main species grown for ornamental purposes of Aglaonema
There are about fifty species among which we remember:
L'Aglaonema modestum It is a plant native to China with very slow growth.It is characterized by leaves of a beautiful green color, waxy, ovate-sharp, 15-20 cm long, petiolate that with age tend to fold downwards. The central vein of the leaves is mottled.
It produces a typical inflorescence of the genus: a green-colored spathe with a cream-white spade. It is a species that more than the others is resistant to low temperatures (10 ° C) as well as to high temperatures.
L'Aglaonema pseudobracteatum it is a robust plant and for this reason it is one of the species that are more easily found on the market. It can reach 80 cm in height and has beautiful lanceolate leaves of an intense green color and streaked with creamy yellow.
Another peculiarity that makes it particularly pleasant are the petioles of the leaves and the young stems which are white speckled with green. It produces white spathe.
L'Aglaonema crispum it is a plant that can reach 90 cm in height with very large, leathery, oval and sharp and variously mottled leaves.
L'Aglaonema costatum it is another splendid specimen of this genus.It is characterized by heart-shaped leaves of a beautiful intense green color and shiny white as the central rib.
They are plants native to Malaysia and India and have the particularity that the stems are so short that they seem to lack them. It produces white spathe.
L'Aglaonema treubi it has narrow leaves, quite leathery and often streaked with silver-gray.It is a native species of Indonesia and is very common as a houseplant.
L'Aglaonema pictum It is characterized by variously mottled dark green leaves. It blooms in midsummer with the production of a beautiful yellowish-green spathe.
They are plants native to Sumatra.
L'Aglaonema commutatum is a plant native to the Philippines characterized by leathery, smooth, lanceolate leaves of a beautiful dark green color with silver streaks along the secondary veins.
It produces a creamy white spathe and a whitish spadix, plants that can reach over a meter in height.
L'Aglaonema versicolor it has all the characteristics of the genus with oval-shaped leaves of green color variously mottled.
L'Aglaonema oblongifolium it is certainly the largest species of the genus reaching a height of 1.2 m and even more. It has the typical leaves of the species: oval, leathery, green speckled with white. The spathe is a beautiful yellow color and the spadix is white. It is a plant native to Malaysia. There are many varieties, among which we mention the variety Curtisii, the most widespread on the market with green leaves with silver-gray streaks that start from the central vein to the edge of the leaf. It produces very light green spathe in the summer.
L'Aglaonema angustifolium it is characterized by erect, oval and sharp leaves with depressed veins which give the plant a rippled appearance.
L'Aglaonema roebelinii (once belonging to the genusSchismatoglottis always from the family of Araceae) has light green leaves, variously embossed with silver, quite large. It is a fairly slow growing plant.
Growth environmental conditions forAglaonema
The Aglaonema they are plants that are not difficult to cultivate.We just keep in mind that all species are slow-growing enough so we must not be in a hurry to want to see them immediately tall and robust ..
They are plants that love the air so it is good to ensure a good exchange of air in the environment in which they are housed but paying attention to currents, especially cold air that are not tolerated.
Light the plant needs
They are plants that do not require large amounts of light in fact they live well even in the penumbra even if they prefer abundant light (not direct sun). Light is especially important for variegated leaf species as a lack of it causes it to lose its mottling.
Optimal cultivation temperature ofAglaonema
The Aglaonema they require a lot of heat. In fact, the optimal cultivation temperatures are 16 ° C during the night and 18 ° C during the day. In any case, temperatures must not drop below 15 ° C.
How to properly water theAglaonema
It is a plant that should be watered often during the spring - summer period so that the soil is moist, not soaked.
Make sure the soil surface is dry between waterings.
L'Aglaonema it takes advantage of frequent nebulizations as it likes a humid environment.
It is a good practice to place the vase on a saucer in which gravel or pebbles have been placed, in which there will always be a trickle of water to ensure a good moisture content, making sure that the bottom of the vase is not in contact with the water. .
Soil to be used forAglaonema and how to repot
They are slow growing plants so it is sufficient to repot every 2-3 years, at the beginning of spring when the temperatures have reached 18-21 ° C as to recover, they need quite high and above all stable temperatures.
A mixture of peat and leaf soil is used without compressing the soil too much around the roots as they do not like to be constrained.
Ideal fertilization forAglaonema
During the spring - summer period, theAglaonema every two weeks using a liquid fertilizer diluted in irrigation water.
Use fertilizers that in addition to having the so-called macroelements such as nitrogen (N), phosphorus (P) and potassium (K) as well as microelements such as iron (Fe), manganese (Mn), copper (Cu), zinc (Zn ), boron (B), molybdenum (Mo), all important for a correct and balanced growth of the plant.
Slightly decrease the fertilizer doses compared to what is reported in the package as they are always excessive.
L'Aglaonema it blooms in summer producing the classic spathe inflorescence.
Artificial pollination ofAglaonema
A fairly easy thing to accomplish, at least you can try, is theartificial pollination ofAglaonema to obtain new varieties.
If you want to try it, proceed as follows: take a soft camel hair brush. Pre-moisten the spadix and then pass the brush in the upper part of the spadix to recover the pollen and then pass it delicately in the lower part to fertilize the female flowers.
Since the environment in which the plant is located certainly does not have a high rate of humidity, wrap the spadici with damp paper and close everything with plastic bags. Leave it like this for 24 hours and then take it all off and let mother nature do it.
If everything went well, after some time you will see some protuberances appear in the spadix as evidence that the fruit is developing from which you can then retrieve the seeds and proceed as indicated in the "multiplication" paragraph.
How to prune without errorsAglaonema
The plant cannot be pruned. The leaves that gradually dry up must simply be eliminated to prevent them from becoming a vehicle for parasitic diseases.
I will never tire of repeating it: the tool you use for cutting (be it scissors, shears, knife) must be cleaned and disinfected (preferably flame-retarded) to avoid infecting the tissues (as well as the hands).
Guide on how to multiply theAglaonema to have new plants
The multiplication occurs by cutting, by seed or by division of the plant.
When choosing the technique to be adopted, it must be borne in mind that multiplication by seed has the disadvantage that, when genetic variability takes over, you are not sure that you will get specimens equal to the mother plant. If you want to get a very specific plant or you are not sure of the quality of the seed that is being stabilized, it is good to do the multiplication by cutting.
MULTIPLICATION FOR TALEA
The cuttings are nothing more than the shoots that develop at the base of the plant (suckers). Pick them up with some leaves and some roots. Plant them in a soil as indicated for adult plants and keep them at a temperature around 18-20 ° C.
When the new shoots start to appear it means that the new plant has rooted well and therefore at that point treat it as an adult plant.MULTIPLICATION BY SEEDS
The multiplication by seeds is carried out in early spring (March) by distributing the seeds of the plant as evenly as possible given the small size, tucked parallel on a soil for seeds.
Given their small size, to bury them, push them under the ground using a flat piece of wood.
It would be a good idea to add a broad spectrum fungicide to the irrigation water, in the doses indicated in the package, to prevent any fungal attacks.
The tray containing the seeds should be kept in the shade, at a temperature around 21 ° C and constantly humid using a sprayer to completely moisten the soil, until the moment of germination.The tray should be covered with a glass plate or a transparent plastic sheet that will ensure a constant temperature and will prevent the soil from drying out too quickly.
Once the seeds have germinated, the glass or plastic sheet is removed, and as the seedlings grow, the amount of light is increased (never direct sunlight), the temperature is reduced to around 18 ° C and good ventilation.
Among all the plants born, there will certainly be those less vigorous than others. Identify and eliminate them in this way you will guarantee more space for the most robust plants.
Remember that plants born from seed may not be the same as the plant from which you obtained the seeds, which is achieved only by multiplying parts of the mother plant.
At the time of repotting, if the plant is large enough, you can divide and plant each portion in individual pots as indicated in the paragraph "repotting". This technique is indicated for those species that have a very short stem, as an example in A. costatum .
Parasites and diseases that can affect theAglaonema and how to cure them
It is not a particularly disease-prone plant. More than anything else we have to talk about bad cultivation technique.
If the leaves show this symptom it means that the plant has either been watered insufficiently or too much.
Remedies: make an analysis of how you raised it bearing in mind that the ground must always be slightly damp not soaked so if the ground is too wet, let it dry (at least remove it with all the earth bread, and leave it in the air until until it has dried) if it is too dry, water it for the future and better regulate the irrigations.
Leaves that appear weak, aching and turn yellow
This is the classic symptom of too low a temperature.
Remedies: move the plant to a warmer place.
Burnt leaves that curl up
This is the classic symptom of excess light: the plant has been exposed to direct sunlight.
Remedies: move the plant to a more suitable place.
Leaves starting to turn yellow, appear mottled with yellow and brown
If the leaves begin to turn yellow and after these manifestations they crumple, assuming an almost dusty appearance and fall and if by observing carefully you notice thin cobwebs, especially on the underside of the leaves, you are most likely in the presence of an attack of red spider, a very annoying mite which is often found in these plants.
Remedies: increase the humidity around the plant with nebulizations to the leaves (the lack of humidity favors their proliferation) and possibly, only in the case of particularly serious infestations, use a specific insecticide. If the plant is not particularly large, you can try cleaning the leaves to mechanically eliminate the parasite, using a soapy cotton ball. After that, rinse the plant thoroughly to get rid of all the soap.
Curious facts aboutAglaonema
The genus name comes from two Greek words:aglao "Splendor" e nema "Thread" to indicate the luster of the stem filaments.
It has been found that the leaves of numerous species of Aglaonema they are poisonous to pets. Therefore, if you have dogs or cats at home, be very careful that they do not get close to the plant.
Heterogeneous aglaonema: care at home
Many growers prefer to start beautiful and unusual exotic flowers, plants such as worries and Aglaonema. Care at home for her is not problematic. Like all houseplants, flowers require special temperature conditions, regular watering, fertilization, adequate lighting. Evergreen Aglaonema came to us from India, in appearance it is very similar to dieffenbachia, it differs only in the duration of flowering, tillering, narrow leaves.
Today, there are more than 100 species of this plant. Several distinct types: polished, Freebach, treyby, painted, ribbed. Florists often stop choosing the Silver Queen setup. Beautiful patterned leaves with silver spots assigned to Aglaonema. Care at home after it practically does not differ from other types of care for this family. If everything was done correctly, the leaves of the beauties turn completely silver, and it will release a white or yellowish flowers.
Since this plant came to us from India, it is not surprising that Aglaonema so loves warmth. Nursing home must ensure the maintenance of temperature between 20-25 ° C. Flower both natural and artificial light, but direct sunlight, can not stand, because it can cause burns, disfiguring leaves. It is also not recommended to put aglaonemu in areas where there is smoke on drafts.
The plant is conducive to frequent watering, loves moisture, but does not stagnate, leading to root rot. It is very important to respect the golden mean. Water should always be used to settle, in the winter less, and more often in the summer it must be watered flower. Aglaonema every two years transplanted to a new, more spacious pot. This is usually done in the warm season: spring or summer. Since it is a poisonous plant, its sap can irritate the skin. To replant better flower in gloves after the procedures should wash hands with soap and water.
The substrate can be purchased ready-made, mount the most common soil for houseplants. With self-cooking gruntosmesi it should be remembered that it should be dissolved, so that the sheet you want to add to the earth coal, humus, sand and peat. Usually propagated by Aglaonema cuttings. nursing home involves spring preform seedlings. Cuts are cut at the base and immediately planted in a high pot, it is necessary for the rapid development of the root system. But adults need to grow low potted plants.
In some cases, it can start to hurt Aglaonema. Care (photo gives an idea of what a healthy plant should look like) in this case should be directed towards error correction. intertwined leaves and brown tips speak of the dry earth or air too dry. High in chlorine in water or in low light conditions Aglaonema can begin to yellow. When flowering, due to low temperatures, they are often attacked by gray mold. If you eradicate the causes of the disease, the plant will again give you a beautiful appearance and lush greenery.
General characteristics of Mimosa
There Mimosa, Acacia dealbata, is a perennial plant from Australia that belongs to the family of Fabaceae (Acacias, Mimosaceae).
There plant, in a rustic state, it reaches considerable, even higher than 20 meters.
The roots they are superficial and underdeveloped and for this reason they need a brace to develop in an erect way.
If you live in ground floor plant the Mimosa far from home to prevent the tiles of your floor closer to it can suffer damage.
There Mimosa it has a very superficial root system with horizontal development and for this reason it tends to lift the tiles of the house floor.
The trunk it is smooth with green-greyish bark.
THE branches tubular with erect - drooping habit are covered with dense evergreen foliage.
The leaves from the green-silver color they are bipinnate that is formed by many leaflets perpendicular to the main rib.
THE flowers, racemes gathered in clusters of a beautiful yellow color, soft to the touch and delicately scented, are the symbol of Women's Day which occurs on 8 March.
THE fruits mimosa are gods pods containing 5-6 blackish seeds similar to those of Robinia.
Flowering: The mimosa blooms between February and March giving spectacular yellow-gold spots.
New Guinea plant: cultivation and care
The New Guinea plant prefers bright areas but the direct sun is absolutely to be avoided, as it causes their rapid wilting. The summer temperatures, on the other hand, are bearable. There flowering is provided from March to the first cold, but it can happen that in milder winters it can give surprises.
How much to plant New Guinea? The ideal period is from March to April, in spring, in order to avoid too cold or too hot temperatures. It is preferable that the soils are soft and rich in peat. Watering must be periodic and never too abundant, better in the morning and without wetting the leaves too much, so as to avoid mold or fungus. The plant, in fact, suffers both from too much water in the soil and from drought. To promote rich flowering, it is also recommended to add liquid fertilizer to the water for about 3 times a month.
Acidity of Aglaonema
Aglaonema is very poisonous, and therefore when caring for the bushes, try to carry out all manipulations in rubber gloves, since even a slight infiltration of juice on the skin or its contact with the leaves and fruits of the plant in sensitive people can cause severe irritation.
Above all, it is necessary to take responsibility for choosing the place for the pet to be installed if there are small children in the house.
