The Aglaonema ‘Red Valentine’, a Chinese Evergreen cultivar, is cherished for its striking foliage. Its dark green leaves are vibrantly splashed with red and pink hues. This plant’s attractive appearance and straightforward care make it a favored choice for indoor plant enthusiasts.
Red Valentine Plant Care
Light
The ‘Red Valentine’ Aglaonema thrives in bright, indirect light. Placing it near a window with filtered sunlight is ideal for maintaining its vibrant coloration. Direct sun can scorch leaves, while insufficient light may cause red and pink pigments to fade, resulting in a duller appearance.
Watering
Consistent moisture without waterlogging is beneficial. Water the plant when the top few inches of soil feel dry. Overwatering can lead to root rot, causing yellowing or browning leaves. Allowing the soil to dry out completely for extended periods can cause leaf drooping.
Soil
A well-draining, aerated potting mix is suitable. A blend containing peat moss, perlite, or vermiculite provides necessary drainage while retaining adequate moisture. An ideal soil pH for ‘Red Valentine’ ranges from slightly acidic to neutral, typically between 6.0 and 7.0.
Temperature and Humidity
The ‘Red Valentine’ Aglaonema prefers average room temperatures, ideally between 65-85°F (18-29°C). Shield the plant from cold drafts or sudden temperature fluctuations, which can cause stress. Moderate to high humidity levels are appreciated; increase humidity by misting leaves regularly or placing the pot on a pebble tray filled with water.
Fertilizing
During the active growing season (spring and summer), the ‘Red Valentine’ Aglaonema benefits from regular fertilization. Apply a balanced liquid fertilizer, diluted to half-strength, monthly. During fall and winter, when growth slows, reduce or cease fertilization entirely.
Repotting
Repotting the ‘Red Valentine’ Aglaonema is generally needed every two to three years, or when it becomes root-bound. Select a container only one to two inches larger in diameter than the previous one to prevent the soil from remaining too wet. Handle the plant gently to minimize root disturbance during transfer.
Propagating Red Valentine
Propagating the ‘Red Valentine’ Aglaonema is commonly achieved through stem cuttings. Select a healthy stem at least 4-6 inches long with a few leaves and at least one node. Make a clean cut below a leaf node using sterilized shears or a sharp knife.
Root the cutting in water or directly in a well-draining soil mix. For water rooting, submerge the cut end in clean water, ensuring no leaves are below the waterline. Place it in bright, indirect light and change the water every few days to prevent bacterial growth. Roots typically form within a few weeks.
For soil propagation, optionally dip the cut end into rooting hormone. Plant the cutting directly into a small pot with moist, well-draining potting mix. Maintain consistent moisture and bright, indirect light until new growth appears.
Common Issues with Red Valentine
Several common issues can affect the ‘Red Valentine’ Aglaonema, often signaling improper care. Leaf discoloration, such as yellowing, frequently indicates overwatering, underwatering, or a nutrient deficiency. Brown leaf tips or edges can point to low humidity, direct sun exposure, or fluoride in the water.
Pest infestations are another concern. Common houseplant pests like spider mites, mealybugs, and scales can affect Aglaonemas. Signs include webbing, sticky residue, or visible insects. Treat infestations with horticultural oils like neem oil or insecticidal soaps, following product instructions.
Leggy growth (stretched stems, sparse foliage) and a lack of vibrant red coloration typically result from insufficient light. Adjusting the plant’s location to a brighter spot can address these issues.
Red Valentine Toxicity
The Aglaonema ‘Red Valentine’ contains insoluble calcium oxalate crystals, making it toxic if ingested. All parts of the plant contain these crystals, which can cause irritation. Symptoms in humans or pets may include irritation and burning in the mouth and throat, swelling, difficulty swallowing, and gastrointestinal upset. Keep this plant out of reach of children and pets to prevent accidental ingestion. If ingestion is suspected, seek immediate medical or veterinary attention.
