Aglaonema
Aglaonema is a genus of flowering plants in the Araceae family. These evergreen perennials are native to tropical and subtropical regions of Asia and New Guinea, but they are extremely popular houseplants elsewhere. They generally grow between 12-24 inches tall and they can live for many years with the proper care. Aglaonema plants produce attractive foliage that ranges in color from light green and variegated to dark green, burgundy, pink, and silver. Aglaonema are generally tough, low maintenance plants that can withstand low light and drier air indoor environments as well as outdoor conditions.
Aglaonema can tolerate drier air but they should be watered regularly in the warmer months. To ensure that your plant stays healthy, always check its soil and water when it's slightly dry. Let the soil dry out completely between waterings and if possible, water with distilled or rainwater. You should also avoid getting water on the foliage as this can cause damage.
Aglaonema plants can thrive in low light levels but prefer bright, indirect light. They can cope with direct sunlight on occasion but make sure their exposure is limited and that you place them away from hot, sunny windows. Ensure that they are not in a spot where they are exposed to air conditioners or drafts from outside.
Aglaonema prefer temperatures between 65-75°F and will need to be moved away from drafts and air conditioners. They will not survive in temperatures that drop below 60°F or above 80°F. If they are exposed to temperatures outside of this range you will need to take steps to either warm up or cool down the environment.
Aglaonema prefer slightly higher humidity levels than the typical household. They do well with regular misting and can be placed in a pebble or tray of water to raise the humidity levels in the vicinity. They will also benefit from a humidifier if available.
Aglaonema prefers a well-draining, nutrient-rich soil. Choose a pre-mixed soil made specifically for houseplants or mix your own, ensuring that it has plenty of organic matter. A combination of potting soil, peat moss, and perlite is ideal. The soil should be kept slightly moist but not wet.
Aglaonema should be fertilized during the summer months when the plant is actively growing. Use a balanced liquid fertilizer, diluted to one-fourth of the strength suggested on the label, and feed every two weeks. In the winter, fertilize only once a month. During the blooming season, switch to an all-purpose fertilizer with a higher phosphorus content to promote flower production.
Aglaonema can be affected by several pests such as aphids, mealybugs, spider mites, and whiteflies. Monitor your Aglaonema frequently for signs of pests, such as yellowing of foliage or webbing. Treat known infestations with appropriate insecticides, according to the manufacturer’s instructions. If the infestation is severe, it may be best to discard the plant and purchase a new one.
Aglaonema plants should be repotted every two to three years to ensure that the soil doesn’t become compacted. When repotting, choose a pot with drainage holes and a potting soil mix designed for houseplants. The plant should be lifted from the pot and any excess soil from the roots should be removed. Place the plant in its new pot and use a trowel to fill in the gaps.
Aglaonema is a low-maintenance plant, so there is little need to prune. You may occasionally need to trim off damaged pieces of foliage or remove old leaves. When pruning, make sure to use sharp, sterile tools and always wear gloves to avoid any potential irritations.
Aglaonema thrives in humus, so adding a thick mulch to the soil around the plant can help to keep the soil moist and rich. Choose a mulch that is free of weed seeds and try to avoid any mulches that contain chemical fertilizers.
Aglaonema can be propagated from cuttings or seeds. To propagate from cuttings, simply cut off a piece of stem that is at least 3 inches long. Put the cutting in water or a moist and well-draining potting mix and make sure it is kept at warm temperatures. Water the cutting regularly and it should take root in two to four weeks.
Aglaonema plants don’t need any support as they are quite sturdy plants. However, if you wish, you can use a stake or trellis to help keep the plant upright as it grows.
Aglaonema does not need a rest period, but it should be fertilized less in the winter months when the plant is not actively growing. During this time, focus on keeping the soil slightly moist but not wet.
Aglaonema is toxic to cats and dogs if ingested and can cause skin irritation in humans if the sap is exposed to the skin.
