Size

Depending on the species, Cymbidium's height ranges from 40 cm to 1.5 meters. Its flower stalk can reach up to 1 meter, while flower diameters vary from 5 to 15 cm.

Flower stalks often carry up to 20–30 flowers, creating stunning decorative displays. Larger specimens are commonly used for decorating winter gardens and floral arrangements.

Growth intensity

Cymbidium grows at a moderate rate. During the active growing season (spring through autumn), it produces new shoots, roots, and flower buds.

In winter, growth slows, and the plant enters dormancy, requiring minimal care. Proper maintenance helps stimulate regular flowering.

Lifespan

With proper care, Cymbidium can live up to 20 years, blooming abundantly every year. Regular repotting, removing old pseudobulbs, and refreshing the substrate extend its lifespan.

Temperature

The optimal daytime temperature ranges from +18 to +25°C, while nighttime temperatures should be +12…+15°C. Temperature fluctuations between day and night stimulate blooming, making it suitable for outdoor placement during warm months.

Sudden temperature changes and drafts may cause bud drop and slow down growth.

Humidity

Cymbidium requires high air humidity, between 60% and 80%. Use humidifiers, trays with wet pebbles, and regular leaf misting with soft water to maintain this level.

A lack of humidity can cause root drying and leaf spotting, reducing the plant's decorative appeal.

Lighting and room placement

Cymbidium needs bright but diffused light. Ideal placements include windows facing east or west. Direct sunlight may cause leaf burns.

In winter, use grow lights to provide 12–14 hours of daily light, supporting active growth and regular blooming.

Soil and substrate

Cymbidium requires a light, well-aerated substrate with good water retention capacity. The optimal potting mix includes:

• Conifer bark (3 parts): Provides root aeration and prevents rot.
• Perlite or vermiculite (1 part): Retains moisture and prevents water stagnation.
• Peat (1 part): Maintains a slightly acidic pH of 5.5–6.5.
• Sphagnum moss (small amount): Helps retain moisture.

A drainage layer of expanded clay, about 3–5 cm thick, is placed at the bottom of the pot to prevent waterlogging.

Watering

During summer, Cymbidium should be watered generously using the immersion method, soaking the pot in water for 15–20 minutes. Watering is done 1–2 times per week, ensuring excess water drains completely. The substrate should dry slightly between waterings but never completely.

In winter, watering frequency is reduced to once every 10–14 days. Watering is done in the morning so that water evaporates before nightfall, preventing root rot and fungal infections.

Fertilization and feeding

From spring to fall, Cymbidium should be fertilized every two weeks with NPK 10:20:20 or 4:6:6 formulations, promoting root growth, bud formation, and shoot development. Fertilizer is applied only after prior watering to avoid root burns.

In winter, feeding is stopped. Organic supplements such as potassium humate or seaweed extract can be applied once a month to maintain plant health.

Propagation

Cymbidium can be propagated by dividing the bush or by keikis (offshoots) formed on flower stalks. Division is performed in spring when the plant is actively growing. Each division should have several roots and one or two pseudobulbs.

Seed propagation is a complex process requiring sterile conditions. Seeds are sown on nutrient agar media in laboratory environments, and full development takes several years.

Flowering

Cymbidium blooms 1–2 times a year, with flowering lasting from 2 to 4 months. Buds open sequentially, creating a prolonged decorative effect.

Bright, diffused light, regular watering, and balanced fertilization are essential for abundant flowering. After flowering, flower stalks are pruned to stimulate new shoot growth.

Seasonal care

In spring, active growth begins with the formation of new shoots and flower buds. During this period, the orchid should be regularly fertilized and watered abundantly.

In winter, the plant enters dormancy, and its growth slows. Watering is reduced, feeding is stopped, and the temperature is maintained at +12…+15°C.

Care specifics

Key care requirements include bright, diffused light, stable air humidity (60–80%), and regular watering. Leaves should be wiped with a damp cloth to remove dust.

The plant should not be moved during flowering to avoid bud drop. It is important to monitor root health, repot the plant every 2–3 years, and fertilize during the active growth phase.

Indoor care

Cymbidium is best placed near east- or west-facing windows. In winter, grow lights are used to extend daylight hours. Watering is done using the immersion method, avoiding water stagnation.

Humidity is maintained with air humidifiers, misting, or trays with wet clay pebbles. Fertilization is done every two weeks during active growth.

Repotting

Repotting is done in spring or after flowering, every 2–3 years. Transparent plastic pots with drainage holes are used to provide light access to the roots.

The entire substrate is replaced, and damaged roots are removed. After repotting, the plant is not watered for 3–5 days to allow the roots to heal.

Pruning and crown shaping

After flowering, dried flower stalks and dead leaves are removed. Pruning is done with sterile tools, and cut areas are sprinkled with crushed charcoal to prevent infection.

Potential problems and solutions

Common issues include root rot due to overwatering, bud drop due to insufficient light or drafts, and leaf spots due to cold exposure.

It is recommended to adjust care conditions, treat the plant with fungicides in case of fungal infections, and ensure optimal temperature and lighting.

Pests

Common pests include spider mites, scale insects, aphids, and mealybugs. Insecticide treatment is carried out at the first signs of infestation.

Air purification

Cymbidium actively absorbs carbon dioxide and releases oxygen. Its leaves trap dust and toxins, improving the indoor microclimate.

Safety

The plant is safe for children and pets as it contains no toxic substances. However, people prone to allergies to flower pollen should avoid direct contact with its leaves and flowers.

Winter care

In winter, Cymbidium requires a temperature drop to +12…+15°C, reduced watering, and discontinued feeding. Active care is gradually restored before spring.

Medicinal properties

Cymbidium has antioxidant and antiseptic properties due to the organic acids and essential oils it contains.

Traditional medicine use

In some cultures, orchid extracts are used to boost the immune system, improve skin health, and support overall body wellness.

Landscape design use

Cymbidium is ideal for decorating winter gardens, greenhouses, and hanging compositions due to its striking flowers.

Compatibility with other plants

Cymbidium pairs well with ferns, anthuriums, and other decorative plants, creating harmonious tropical compositions.
