The Aglaonema is a member of the Aroideae family. This genus includes about 20-50 species. Under natural conditions the plant is found in the rain forests of tropical New Guinea, the Malay Archipelago as well as in Southeast Asia along riverbanks in the lower forests and plains.
Properties of Aglaonema
Aglaonema is an evergreen herbaceous plant. The short and straight stem is quite fleshy.
There are some species whose trunk begins to branch at the base. Only adult plants have a stem, and it is formed by the shedding of the lower leaf plates. The color of the leaves depends directly on the species and variety of the plant. The dense, leathery-to-touch leaves are ovate or lanceolate in shape. They are attached to the trunk by petioles, which may be long or short.
Leaf edges are solid, with the plate patterned and the middle vein depressed on its front surface and convex on the underside. On the top of the plant, 1 to 3 cobs with a greenish-white covering grow from the leaf axils, they are the aglaonema inflorescences. The cobs are divided into 2 types depending on the type of the plant:
- thick club-shaped - up to 10 mm across and 40 mm long;
- thin cylindrical - about 60 mm long and 5 mm in diameter.
Fruit is a juicy berry with one seed inside that has a deep orange or white color. The berry ripens after 6-8 months.
Home care for aglaonema
Wild Aglaonema prefers to grow in shaded areas. Therefore, the plant needs semi-shade when growing at home as well. If the foliage is exposed to direct sunlight, it can cause burns. If the variegated form is grown, it will need bright diffused sunlight, otherwise its decorativeness will be lost.
In summer the plant feels fine at 20-25 degrees, while in winter it should not be below 16 degrees.
You should protect the plant from draughts, because they can kill it. Also the flower reacts extremely negatively to sudden temperature changes.
How to water
Water Aglaonema only with soft water. Water abundantly as soon as the top layer of substrate dries out. The plant especially needs timely watering in spring and summer, when it has a growing season.
In winter, watering is done after a couple of days after the top layer of substrate dries out. It should be remembered that such a flower can ruin as over-drying of the ground ball, and stagnant liquid in the substrate.
This plant needs increased air humidity, which means that it must be systematically moistened from a sprayer and not only. If there is too little humidity in the room where the aglaonema is located, the development of its leaf plates will slow down, and deformation will occur, with the tips and edges of the plates withering. To increase air humidity, experienced growers are advised to pour pebbles or expanded clay pebbles in a pan and pour a small amount of water into it, and place a pot with a flower on top.
Make sure that the liquid and the bottom of the pot is not in contact. During the fall and winter if the room is cool, spray with great care.
The Aglaonema does not need to be fertilized in the winter. Fertilize the plant from the first days of spring to the last days of summer once every two weeks and use alternating mineral and organic fertilizers. The concentration of the nutrient solution should be as stated on the fertiliser pack.
Potting young plants once a year in the springtime. Mature shrubs should also be transplanted in the spring, but much less often (once every 4 or 5 years). Substrate for planting such a flower should consist of humus and leaf soil, sand, charcoal and peat, which are taken in a ratio of 1:6:2:2:1. You can take a soil mixture consisting of leaf soil, peat and sand (2:1:1), in it should be poured a small amount of fine charcoal. To avoid water stagnation in the soil, a good drainage layer should be made at the bottom of the pot when planting.
Such a flower can be grown on hydroponics.
Is Aglaonema poisonous
If the sap of the shrub or its fruit comes in contact with your skin or mucous membranes, it may cause irritation. Wash your hands with soap and water when you are finished with the flower

The propagation of aglaonema by cuttings
The aglaonema can only be propagated by cuttings when its trunk begins to branch or when the trunk is clearly visible after the rosellate stage is complete. The stem should be cut off as is done with the apical cuttings. It is then divided into several parts, each of which should reach 90-100 mm in length, with leaf plates on each cuttings. Leave the cuttings for 24 h in the open air to dry out and do not forget to treat the cutting places with crushed charcoal.
The cut end of the cuttings should then be buried 50 mm into a substrate consisting of sand and peat. A container with cuttings removed to a warm place (22 to 25 degrees), if everything is done correctly, the roots will need to appear within 4 weeks. If during the rooting will be used bottom heating, the cuttings will give roots after 20 days. If you do not have a mini-greenhouse, cuttings are recommended in the spring or summer. Once the cuttings are rooted, they should be planted in individual pots filled with the substrate used for planting adult aglaonemas.

Growing from seed
If cared for properly, this plant is quite likely to have blooms in summertime. Note that the blanket-flower is not of much ornamental value. It can also be self-pollinated and produce ruby or orange berries.
Wait until the berries will ripen directly on the shrub, and then you can use them for sowing. Note that this method of propagation does not always maintain the characteristics of the Aglaonema species.
Seed the fruit pulp and rinse it well under running water before sowing it in pots filled with a mixture of sand and peat (1:1). The seeds should not be stored because they quickly lose their germinability.
Seeds should be placed in a warm place and systematically watered.
The seedlings will show up relatively quickly. As soon as the first true leaf plates are formed, the plants should be sprouted into small individual pots. After the bushes will grow, make them transplant into larger pots. You will have developed shrubs after 3 or 4 years.
It is also possible to propagate this plant by dividing the rhizomes during replanting.
- The leaves will shrivel and the tips will brown. The humidity in the room is excessively low and various pests can also settle on the flower. Do not forget to regularly moisten the shrub with water spray, as well as pour water into a tray, previously filled with peat or keramsit.
- Foliage curling. This can occur when the temperature drops suddenly or if the flower is exposed to a draft.
As a rule of thumb, in addition to the twisting, the edges become brown on the plates.
- White-yellow spots have formed on the foliage. These appear as a result of sunburn. The bush is removed to the shade and waited until it has cooled, then its foliage is moistened with room temperature water.
- Slow bush growth, foliage turns brown.
The plant has been watered with cold or hard water. Water the Aglaonema only with water that has stood for at least 24 hours. To soften the water, add 0.2 grams of oxalic acid to a bucket, mix well and leave for 24 hours. You can also soften the water with citric acid.
Spider mites, mealybugs, aphids, whiteflies and thrips may be pests.
