How to Grow Aglaonema 'Silver Queen'? Cultivation Methods and Precautions
Aglaonema 'Silver Queen', also known as Silver Queen Chinese Evergreen, Silver Queen Aglaonema, Silver Queen Dieffenbachia, etc., is a perennial herbaceous plant of the genus Aglaonema in the Araceae family. Its leaf color is beautiful, it is particularly shade-tolerant, and it has a unique air-purifying ability. Placing a potted plant in a hall or room will make you feel bright and comfortable. At present, using its cut leaves for flower arrangements, leisure, or decorating outdoor environments has become fashionable. Now let us take a look at the cultivation methods and precautions for Aglaonema 'Silver Queen'!
Growth Habits of Aglaonema 'Silver Queen'
Aglaonema 'Silver Queen' prefers a warm, humid, and semi-shaded environment. It is not cold-tolerant, fears strong direct sunlight, and is not drought-tolerant. The optimum growth temperature is 20-27°C, from March to September it is 21-27°C, and from September to the following March it is 16-21°C. The winter temperature should not be lower than 12°C. A mixed soil of half fertile leaf mold and half river sand is suitable. It is suitable for dark rooms with poor ventilation. The suitable temperature is 15-21°C. It likes to live in a constant-temperature environment. If watered with warm water, it can survive for a longer time.
Propagation Methods of Aglaonema 'Silver Queen'
1. Cuttage: Propagation of Aglaonema 'Silver Queen' by cuttage is carried out in late spring and early summer. The lower leaves of mature plants tend to wither, causing the stem to become bare. The top stem can be cut for cuttings, and the base left behind can sprout new shoots again.
2. Division: Propagation of Aglaonema 'Silver Queen' by division is generally carried out in February to March in conjunction with repotting. The clustered plant is divided into several root-bearing plants and planted separately. It can also be divided and planted in other seasons. After division, it can be divided again after three years.
Cultivation Methods of Aglaonema 'Silver Queen'
1. Soil: For potted Aglaonema 'Silver Queen', loose peat soil or turf soil is best. A mix of leaf mold and sandy loam can also be used, and a small amount of diluted ferrous sulfate can be used to acidify the soil.
2. Watering: During the peak growth seasons of spring and autumn, Aglaonema 'Silver Queen' should be watered sufficiently. The potting soil should be kept moist frequently, and the branches and leaves should often be sprayed with clean water close to room temperature to prevent dry leaf tips, but there should be no waterlogging.
3. Light: Aglaonema 'Silver Queen' likes scattered light and is especially afraid of direct sunlight in summer. Outdoors, a 65-75% shade net is needed for shading. Indoors, it should be placed in a bright spot to make the leaf color vivid.
4. Temperature: Aglaonema 'Silver Queen' grows fastest at 20-24°C and stops growing above 30°C. In summer, heat prevention and cooling should be carried out with attention to ventilation. In winter, it should be cultivated in a greenhouse or room, and the overwintering temperature should not be lower than 5°C.
5. Fertilization: In late spring and early summer, Aglaonema 'Silver Queen' can be given a small amount of acidic nitrogen fertilizer. In summer, increase nitrogen fertilizer. In early and mid-autumn, some compound fertilizer can be applied. In late autumn and early winter, stop fertilizing.
⟦NL>6. Pests and diseases: When the plant clusters of Aglaonema 'Silver Queen' are dense and ventilation is poor, it is susceptible to scale insects. If scale insects occur, a 50% malathion emulsion diluted 1000-1500 times can be sprayed once every 7 days, for 2-3 consecutive sprays.
7. Pruning: As the Aglaonema 'Silver Queen' plant grows, in order to maintain a good plant shape, the old leaves at the base should be pruned frequently.
8. Repotting: Aglaonema 'Silver Queen' has strong sprouting vitality and grows quickly, easily filling the pot. It should be repotted once every two years.
Precautions for Aglaonema 'Silver Queen'
1. Aglaonema 'Silver Queen' likes to grow in a humid and semi-shaded environment. Once the air is too dry, the sunlight is unobstructed, and the temperature is as high as above 30°C, it is very easy to cause the leaf tips of the Aglaonema 'Silver Queen' plant to wither. When cultivating outdoors in summer, attention should be paid to shading so that the light is not too strong; otherwise, sunburn is very likely to occur. When overwintering in a greenhouse or room in winter, attention should be paid to lighting to prevent the leaf color from fading due to insufficient light.
2. Do not let water accumulate in the pot of Aglaonema 'Silver Queen' (watering too frequently), as this can easily lead to root rot. It is best to water only when the potting soil is dry. If the pot is relatively deep, the watering frequency should be reduced even more. In summer, watering and spraying can be appropriately increased to maintain humidity. There is a saying, “whether it lives or not depends on water”, which shows the importance of watering. Water deficiency can be replenished, but once water accumulates and roots rot, it is very difficult to remedy.
3. If Aglaonema 'Silver Queen' is not repotted for a long time, causing the root system to grow directly against the pot wall, then in a high-temperature, high-drought, or cold environment, it is very easy for the root tips to shrink and necrose, causing them to lose their proper absorption function, which in turn leads to dry and shrunken leaf tips.
4. If the potting soil of Aglaonema 'Silver Queen' is compacted or too sticky and heavy, or if watering is too frequent and excessive, causing the rot of the nutrient fibrous roots of Aglaonema 'Silver Queen', then the root system's ability to absorb water will drop significantly, causing its leaf tips to turn black and the edges to curl inward.
