Aglaonema ‘Katrina’, or Chinese Evergreen ‘Katrina’, is a popular indoor plant known for its striking foliage. Its vibrant green, red, and pink patterns add a tropical touch, making it a favored choice for both new and experienced plant enthusiasts due to its ease of care.
Aglaonema Katrina Care
Light Needs
Aglaonema Katrina thrives in bright, indirect light. An east or north-facing window is ideal. While it tolerates lower light, growth may slow, and leaf coloration might fade. Avoid direct afternoon sun, as it can scorch leaves.
Watering
Maintain consistent soil moisture, but avoid overwatering. Water thoroughly when the top 1-2 inches (2.5-5 cm) of soil are dry. Soggy soil causes root rot. Drooping leaves signal thirst; yellowing leaves can indicate overwatering.
Soil Requirements
Aglaonema Katrina prefers a well-draining, moisture-retentive potting mix rich in organic matter. A blend of organic potting soil with perlite or cactus soil improves drainage and aeration. The ideal soil pH is slightly acidic, ranging from 6.0 to 6.5.
Temperature and Humidity
Aglaonema Katrina prefers warm temperatures, ideally 65°F to 80°F (18°C to 27°C). Temperatures below 55°F (13°C) can cause tissue damage and inhibit growth. High humidity is beneficial; low humidity can cause leaf edges to dry and turn brown. Misting regularly or using a pebble tray increases ambient humidity.
Fertilizing
During spring and summer, Aglaonema Katrina benefits from regular fertilization. Apply a balanced liquid houseplant fertilizer, diluted to half strength, every 4-6 weeks. Over-fertilizing can lead to root burn and leaf damage. Fertilization is not necessary during fall and winter.
Common Problems and Solutions
Pests
Aglaonema Katrina can attract common houseplant pests like spider mites, mealybugs, and scale insects. Spider mites cause yellowing or stippling on leaves, while mealybugs appear as small, cottony masses. Regularly inspect the plant and wipe leaves with a damp cloth. For active infestations, insecticidal soap or neem oil are effective treatments.
Diseases
Root rot is a frequent issue. Symptoms include yellowing leaves, wilting, and a foul odor from the soil. To address this, ensure the soil dries adequately between waterings and consider repotting into fresh, well-draining soil after pruning any affected roots. Leaf spot, a fungal disease, manifests as dark spots on leaves, often due to high humidity or poor air circulation.
Leaf Issues
Yellowing leaves indicate overwatering or insufficient light. Brown tips or edges point to low humidity or salt accumulation from tap water. Drooping leaves signal thirst. Ensuring proper watering, adequate light, and sufficient humidity resolves most leaf issues.
Propagating Aglaonema Katrina
Propagating Aglaonema Katrina is done through stem cuttings or division. Stem cuttings involve taking a healthy 4-6 inch stem section with leaves and at least one node. Root these in water, changing it weekly, or directly in a well-draining soil mix. For soil propagation, dipping the cut end in rooting hormone enhances success before planting in moist, porous soil.
Division suits mature plants with multiple stems or offshoots. Carefully separate the plant at the root ball, ensuring each new section has its own roots and foliage, then repot into fresh soil.
Is Aglaonema Katrina Toxic?
Aglaonema Katrina is toxic to humans and pets if ingested. It contains insoluble calcium oxalate crystals. Symptoms include a burning sensation and swelling of the mouth, throat, or skin, and gastrointestinal upset. While not life-threatening, keep Aglaonema Katrina out of reach of children and pets. Wearing gloves when handling the plant during repotting or pruning prevents skin irritation. Always wash hands thoroughly after touching the plant.
