Chinese Cymbidium

Cymbidium sinense, commonly known as the Chinese Cymbidium or Spring Orchid, is a stunning orchid native to Asia. Renowned for its beautiful blooms and unique foliage, it is a favorite among orchid enthusiasts for its relatively easy care and ability to thrive indoors.
Everything it needs
9 essentials at a glance
Watering
Cymbidium sinense prefers to be kept evenly moist but not soggy.
Water every 7-10 days during the growing season (spring and summer), allowing the top inch of soil to dry out between waterings. In fall and winter, reduce watering to every 2-3 weeks. Signs of over-watering include yellowing leaves and root rot, while under-watering may cause leaf tips to brown and shrivel.
Light
This orchid thrives in bright, indirect light, ideally receiving 4-6 hours of filtered sunlight daily.
Avoid direct afternoon sun, which can scorch the leaves. A north or east-facing window is ideal, while south-facing windows may require sheer curtains to diffuse the light.
Soil
Cymbidium sinense prefers a well-draining potting mix, ideally composed of bark, perlite, and sphagnum moss.
The pH range should be between 5.5 and 6.5. Ensure the pot has drainage holes to prevent water accumulation, which can lead to root rot.
Humidity
This orchid enjoys humidity levels of 50-70%.
To increase humidity, consider using a humidity tray filled with water and pebbles, or mist the plant regularly. Signs of low humidity stress include leaf curling and browning leaf edges.
Temperature
Cymbidium sinense thrives in temperatures between 60-75°F (15-24°C) during the day and slightly cooler at night.
It is hardy in zones 10-11 and can tolerate brief periods of cooler temperatures down to 40°F (4°C). Avoid exposing it to extreme heat or cold.
Fertilizing
Use a balanced orchid fertilizer with an NPK ratio of 30-10-10, diluted to half strength.
Fertilize every 2-4 weeks during the growing season and reduce to once every 6-8 weeks in fall and winter. Signs of nutrient deficiency include yellowing leaves and poor growth.
Pruning
Prune dead or yellowing leaves as needed to maintain plant health.
Use clean, sharp scissors or pruning shears to avoid disease transmission. Deadheading spent flower spikes can encourage new growth and blooms.
Repotting
Repot every 1-2 years or when the plant outgrows its pot, typically in spring.
Choose a pot that is 1-2 inches larger in diameter than the current one. Signs it needs repotting include roots growing out of the drainage holes or a compacted potting mix. Carefully remove the plant, clean the roots, and place it in fresh mix.
Propagation
Propagation is best done through division.
In spring, when the plant is actively growing, carefully remove the orchid from its pot and divide the rhizomes, ensuring each division has at least 3-4 pseudobulbs. Re-pot in fresh orchid mix and water lightly until established.
When it's unhappy
Yellow leaves
Why it happens
Over-watering or insufficient light.
How to fix it
Adjust watering frequency and ensure the plant receives adequate light.
Root rot
Why it happens
Excess moisture and poor drainage.
How to fix it
Repot the orchid in fresh, well-draining mix and reduce watering frequency.
Browning leaf tips
Why it happens
Under-watering or low humidity.
How to fix it
Increase watering frequency and humidity levels around the plant.
Poor flowering
Why it happens
Insufficient light or lack of nutrients.
How to fix it
Ensure the plant receives adequate light and fertilize regularly during the growing season.
Pests (e.g., aphids, spider mites)
Why it happens
High humidity and poor air circulation.
How to fix it
Inspect regularly, and treat infestations with insecticidal soap or neem oil.
Care through the year
Spring
In spring, focus on watering regularly as the plant begins to grow. Fertilize every 2-4 weeks and consider repotting if needed.
Summer
During summer, maintain consistent moisture and provide bright, indirect light. Continue fertilizing every 2-4 weeks.
Fall
In fall, gradually reduce watering frequency as the plant enters dormancy. Fertilize less frequently, about every 6-8 weeks.
Winter
In winter, water every 2-3 weeks and keep the plant in a cool, bright location. Avoid fertilizing until spring.
Toxicity & Safety
Cymbidium sinense is considered non-toxic to pets and children. However, ingestion of any part may cause mild gastrointestinal upset. Always monitor pets around houseplants.
