Aglaonema (Chinese Evergreen)

Aglaonema – Chinese Evergreen Care

Growing and caring for Aglaonema, commonly known as Chinese Evergreen, is quite straightforward due to its resilience and adaptability to indoor conditions.

Light: Aglaonema prefers low to medium light and can thrive in areas away from direct sunlight, which can scorch its leaves. It’s ideal for offices or homes with limited natural light.

Soil: Use a well-draining potting mix. A mixture designed for houseplants, which typically includes peat, pine bark, and perlite or vermiculite, works well.

Water: Water your Aglaonema when the top 1-2 inches of soil feel dry. Overwatering can lead to root rot, so ensure the pot has good drainage. They are somewhat drought-tolerant but perform best with consistent moisture.

Temperature and Humidity: Keep your Chinese Evergreen in a warm spot, with temperatures between 65°F to 80°F (18°C to 27°C). Avoid placing it in drafts or near heating and air conditioning vents. It’s sensitive to cold and should not be exposed to temperatures below 60°F (15°C). This plant enjoys high humidity (over 65%) but can adapt to lower humidity levels found in most homes. If your home is particularly dry, consider using a humidifier or placing the plant on a pebble tray with water to increase humidity around it.

Fertilization: Feed your Aglaonema with a balanced, water-soluble fertilizer every month during the growing season (spring and summer). Reduce feeding in fall and winter when plant growth naturally slows.

Pruning: Pruning is not typically necessary for Aglaonema, but you can trim away any yellowed or dead leaves to keep the plant looking its best. Use clean, sharp scissors or pruning shears.

Repotting: Repot your Chinese Evergreen every two to three years or when it becomes root-bound. Choose a pot slightly larger than the current one to give the roots room to grow. 

Aglaonema – Chinese Evergreen Propagation – A Step-By-Step Guide

Propagating Aglaonema or Chinese Evergreen can be a rewarding way to increase your plant collection or share with friends. The process is relatively simple and can be done using a few different methods, primarily through stem cuttings or division.

Propagation through Division

This method is best performed when you’re already repotting the plant, typically in the spring or early summer.

• Remove the Plant: Gently take the plant out of its pot and shake off excess soil from the roots to better see the root structure.
• Identify Division Points: Look for natural separations in the root ball where the plant has multiple stems or offsets.
• Divide the Plant: Using your hands or a clean, sharp knife, divide the plant into smaller sections, ensuring each new plant has a good portion of roots attached.
• Pot up the Divisions: Plant each division in its pot filled with well-draining potting mix suitable for houseplants. Water lightly to settle the soil around the roots.
• Care for New Plants: Place the pots in a warm, brightly lit area away from direct sunlight. Keep the soil moist but not waterlogged as the new divisions establish themselves.

Propagation through Stem Cuttings

Stem cuttings can be rooted in water or directly in soil.

In Water:

• Cut a Stem: Choose a healthy stem and cut a 4-6 inch piece just below a node (where a leaf attaches to the stem). Remove the bottom leaves to expose one or two nodes.
• Root in Water: Place the cutting in a jar of water, ensuring at least one node is submerged. Change the water every few days to keep it fresh.
• Plant the Rooted Cutting: Once roots have developed (usually within a few weeks), plant the cutting in potting soil and care for it as you would a mature plant.

In Soil:

• Prepare the Cutting: Follow the same steps as above for preparing a stem cutting.
• Plant in Soil: Dip the cut end in rooting hormone (optional) and plant it directly in moist, well-draining potting soil. Cover the pot with a plastic bag to create a humid environment.
• Care for the Cutting: Place the pot in bright, indirect light and keep the soil moist. Remove the plastic bag once new growth appears, indicating the cutting has successfully rooted.

Aglaonema cuttings root best in warm temperatures around 70°F (21°C). Patience is key, as it can take several weeks for roots to develop and new growth to appear.

Aglaonema – Chinese Evergreen: Pests, Diseases, Common Problems

Aglaonema, or Chinese Evergreen, is a resilient houseplant, but like all plants, it can encounter pests, diseases, and other common problems.

Pests

Spider mites: These tiny pests thrive in dry conditions and can cause the foliage to look dull and stippled. Increase humidity and wash the plant with water. In severe cases, use insecticidal soap or neem oil.

Mealybugs:  Recognizable by their cotton-like white masses, they suck plant sap, weakening it. Remove them manually using a cotton swab dipped in rubbing alcohol or apply insecticidal soap.

Scale insects:  These can appear as small brown bumps on the stems and leaves, sucking the sap and reducing plant vigor. Scrape them off or treat them with neem oil.

Aphids: These small, green pests suck sap from new growth. Rinse them off with water or treat the plant with neem oil.

Diseases

Root rot:  Overwatering is a common cause, leading to mushy, black roots. Ensure proper drainage and let the topsoil dry out between waterings. If root rot is detected, repot the plant into fresh, well-draining soil and trim away any rotted roots.

Leaf spot diseases: Fungal or bacterial infections can cause spots on leaves. Improve air circulation, avoid wetting the leaves when watering, and remove affected foliage. Fungicide treatments can be used in severe cases.

Common Problems

Yellowing Leaves: Often a sign of overwatering, poor drainage, or too much direct sunlight. Adjust watering habits and ensure the plant is not in a location where it receives harsh, direct light.

Brown Leaf Tips: Can indicate low humidity, too much fertilizer, or fluoride in the water. Use distilled or rainwater if your tap water is fluoridated, and mist the plant regularly to increase humidity.

Slow Growth or Pale Leaves: This might be due to inadequate light or nutrient deficiency. Ensure your Aglaonema is placed in bright, indirect light, and fertilize it with a balanced, diluted fertilizer during the growing season.

Frequently Asked Questions

Does Aglaonema need sunlight?

Aglaonema, or Chinese Evergreen, does not require direct sunlight but thrives in low to medium indirect light conditions. It can tolerate low-light environments well, making it suitable for indoor spaces away from windows or in rooms with minimal natural light. However, some variegated varieties might need brighter light to maintain their unique leaf patterns.

How often do you water Aglaonema plants?

Aglaonema plants should be watered when the top inch or so of the soil has dried out. This usually translates to watering every 7 to 10 days, but the frequency will depend on factors such as the plant’s environment, the season, and the pot size. Overwatering should be avoided to prevent root rot.

What are the disadvantages of Aglaonema plant?

• Toxicity: Aglaonema plants are toxic to pets and humans if ingested, causing irritation and other symptoms, which can be a concern for households with pets or small children.
• Sensitive to Cold: They are sensitive to cold temperatures and drafts, which can limit their placement in colder climates or environments.
• Susceptibility to Pests and Diseases: While generally robust, they can be susceptible to common houseplant pests like spider mites and diseases if overwatered or in poor air circulation.

Does Aglaonema attract bugs?

Aglaonema can attract pests such as spider mites, mealybugs, and aphids, especially if the plant is stressed or if the environmental conditions are not optimal. Good plant care practices and regular inspections can help prevent and control infestations.

Why does my Aglaonema keep dying?

Several factors can contribute to an Aglaonema plant’s decline:

• Overwatering: This is a common issue that leads to root rot, which is detrimental to the plant’s health.
• Poor Lighting: While Aglaonema can tolerate low light, extremely poor light over an extended period can weaken the plant.
• Temperature Stress: Exposure to temperatures below 60°F (15°C) or to cold drafts can cause harm.
• Pests and Diseases: Infestations or diseases can weaken the plant, leading to its demise if not addressed.
• Improper Soil: Soil that does not drain well can hold too much moisture around the roots, leading to root rot.
