Chinese Evergreen Care Guide: How to Grow Aglaonema
Chinese evergreen (Aglaonema) offers something almost no other houseplant genus does: an extraordinary color range — from deep, matte forest green to vivid silver, pink, red, and orange — combined with genuine tolerance for lower light and irregular watering. Whether you want a dramatic red-leaved focal point or a reliable low-maintenance green plant for a dim corner, there's an Aglaonema variety for the purpose.
The key insight for care: the color of your Chinese evergreen tells you how much light it needs. This guide explains that rule and covers all aspects of care. For the broader context of tropical plant care, see the Complete Tropical Houseplants Guide.

Varieties and the Color-Light Rule
The single most useful thing to know about Aglaonema: the more colorful the variety, the more light it needs. This is because vivid pigmentation (red, pink, orange anthocyanins) requires more light energy to produce and maintain than simple green chlorophyll. A dark green Chinese evergreen placed in low light will thrive; the same placement will fade a vibrant red or pink variety toward disappointing, washed-out colors.
| Color Type | Example Varieties | Light Requirement |
|---|---|---|
| Deep green / silver | Silver Bay, Maria, Emerald Beauty | Low to medium indirect |
| Green + silver variegation | Silver Queen, First Diamond | Low to medium indirect |
| Green + yellow/gold | Golden Fluorite, Chocolate | Medium indirect |
| Pink + green | Pink Dalmatian, Cutlass Pink, Stripes | Medium to bright indirect |
| Red + green | Red Anjamani, Siam Aurora, Red Siam | Bright indirect (essential) |
| Orange + red | Wishes, Creta, Harlequin | Bright indirect (essential) |
Light Requirements
Chinese evergreens are adapted to life in the understory of tropical forests in Southeast Asia — they evolved with filtered, indirect light, and they have no tolerance for direct sun, which scorches their leaves rapidly.
Green and silver varieties: Tolerate low light better than almost any other tropical houseplant except the ZZ plant. They perform well in north-facing rooms, offices without windows, and positions far from natural light sources.
Colored varieties (pink, red, orange): Need the indirect bright light of an east or west window, or a position 1–2 m from a south window. In insufficient light, the vibrant pigmentation fades and new leaves emerge in muted, dull tones.
Both color groups share the same "no direct sun" rule — even south-facing window placement needs sheer curtains to filter harsh afternoon sun.
Watering
Chinese evergreens prefer to dry slightly between waterings. Insert your finger 3–4 cm into the soil: if dry at that depth, water thoroughly; if still moist, wait 2–3 days. In summer, watering every 7–10 days is typical. In winter, extend to every 14–21 days.
Water thoroughly when you do water — saturate the entire root zone and allow excess to drain. Chinese evergreens sitting in waterlogged soil or saucers full of water develop root rot, which is the primary cause of death in this species.
Use room-temperature water. Like many tropical plants, Chinese evergreens can be sensitive to fluoride and chlorine in tap water — using filtered water or allowing tap water to sit overnight reduces sensitivity-related brown tipping.
Humidity and Soil
Humidity
Chinese evergreens prefer 40–60% humidity but tolerate typical indoor levels (30–50%) better than more sensitive tropicals like calathea or prayer plants. In dry conditions, brown leaf tips appear gradually. A humidifier or pebble tray improves both appearance and growth rate, but Chinese evergreens are not as demanding as prayer plants in this regard.
Soil
Well-draining is more important than moisture-retentive for Chinese evergreens. Use:
- 60% potting soil
- 30% perlite
- 10% orchid bark (optional, improves aeration)
Avoid very dense, peat-heavy mixes that stay wet for days. The soil should feel moist-to-dry (not soggy) throughout the interval between waterings.
Fertilizing
Chinese evergreens are moderate feeders. Apply a balanced liquid fertilizer (10-10-10) at half strength every 4–6 weeks during the growing season (March–September). Do not fertilize in winter. Over-fertilization is a common cause of brown leaf tips — err on the side of less frequent application. Flush the soil with plain water every 3–4 months to remove accumulated salts.
Repotting
Chinese evergreens need repotting every 2–3 years. They tolerate being moderately root-bound and don't need frequent pot size increases. Repot when roots emerge from drainage holes or growth significantly slows despite good care. Spring is ideal. Move up one pot size only — oversized pots retain excess moisture and increase root rot risk.
During repotting, handle sap carefully — it's an irritant to skin and eyes. Wear gloves when working with cut stems.
Toxicity
All Aglaonema species contain calcium oxalate crystals. These cause oral irritation, drooling, difficulty swallowing, and vomiting in cats and dogs. The sap causes contact dermatitis in sensitive individuals. Keep the plant out of reach of pets and children. Wash hands after handling cut stems or when repotting.
Common Problems
Yellow Leaves
Overwatering is the most common cause — check if soil has been staying consistently moist. Root rot produces progressively worsening yellowing with a musty soil odor. Natural aging of older lower leaves is normal and occasional.
Brown Leaf Tips
Typically caused by low humidity, fluoride in tap water, or salt buildup from over-fertilization. Use filtered water, maintain 40%+ humidity, and flush soil regularly with plain water. Trim brown tips cosmetically if desired.
Fading Color (Colored Varieties)
Insufficient light. Move pink, red, or orange varieties to a brighter indirect location. New leaves will emerge in brighter color once light improves; older faded leaves won't recover.
Mealybugs
White cottony clusters in leaf axils. Treat with 70% isopropyl alcohol on a cotton swab, applied directly to insects. Repeat weekly for 3–4 weeks. Isolate affected plants immediately.
Frequently Asked Questions
Chinese evergreen light needs depend on variety color. Green and silver varieties (like Silver Bay, Maria) tolerate low to medium indirect light — even north-facing rooms. Red, pink, and orange varieties (like Red Anjamani, Pink Dalmatian, Siam Aurora) need medium to bright indirect light to maintain their vivid colors. All varieties should avoid direct sun, which bleaches and scorches the leaves.
Water Chinese evergreen when the top 3–4 cm of soil feels dry — approximately every 7–10 days in summer, every 14–21 days in winter. It tolerates brief drought better than consistently wet soil. Overwatering is the leading cause of death in Chinese evergreens — their roots are susceptible to rot in soggy conditions.
Yes — Chinese evergreen (Aglaonema) contains calcium oxalate crystals throughout all plant parts. Ingestion causes oral irritation, excessive drooling, difficulty swallowing, and vomiting in cats and dogs. The sap can also irritate human skin. Keep the plant away from pets and wash hands after handling cut stems or sap.
Yellow leaves most often indicate overwatering or root rot. Check if the soil has been staying consistently moist — allow it to dry more between waterings. Other causes include insufficient light (overall pale yellowing), cold temperatures below 15°C, or natural aging of the oldest lower leaves. Root rot produces yellowing that spreads rapidly and is accompanied by a musty soil smell.
Brown tips are usually caused by low humidity, fluoride sensitivity in tap water, or over-fertilization. Use filtered or overnight-sat tap water. Maintain humidity above 40% with a humidifier or pebble tray. Flush the soil with plain water every 2–3 months to remove accumulated fertilizer salts. Some brown tipping is normal and cosmetic — trim with scissors if desired.
