About Dendrobium Orchid
One of the largest and most diverse orchid genera, Dendrobium orchids produce elegant sprays of flowers in virtually every color — from pure white and soft lavender to vibrant magenta, yellow, and green. Philippine species and hybrids are particularly stunning, with cane-like pseudobulbs bearing arching flower sprays that can last 4-8 weeks. They are among the easiest orchids to grow in tropical climates and are a staple of Filipino orchid collections. Dendrobium Orchid belongs to the Orchidaceae family and originates from Tropical and subtropical Asia, Australia, and the Pacific Islands. The Philippines is home to over 100 native Dendrobium species..
Dendrobium orchids are arguably the most popular orchid group in the Philippines. Filipino orchid enthusiasts grow them mounted on tree trunks, in hanging coconut shell baskets, and in clay pots filled with charcoal and brick chips. The Philippine Orchid Society regularly features Dendrobiums in shows at SM Aura, Glorietta, and Trinoma. Native species like Dendrobium anosmum are found in Philippine forests and are protected under DENR regulations — always buy nursery-propagated plants. Dendrobium hybrids are widely available at Quezon Avenue plant shops, Dangwa flower market, and orchid vendors at Sunday plant markets in QC and Marikina. They are also popular as cut flowers for leis and corsages at graduations and proms.
Also known as: Den Orchid, Spray Orchid.
Popular Varieties
- Dendrobium phalaenopsis hybrids (most popular, long-lasting sprays, easy to grow)
- Dendrobium anosmum (native PH species, fragrant, cascading purple flowers)
- Dendrobium nobile hybrids (compact, heavily flowered along canes, need cool rest)
- Dendrobium chrysotoxum (golden-yellow clusters, very showy)
How to Plant Dendrobium Orchid in the Philippines
Dendrobium Orchid can be propagated through division, keiki (plantlets), stem cuttings. The recommended method is division of mature clumps or potting up keikis.
Propagation Steps
- Step 1: Wait until keikis (baby plants on canes) develop 2-3 roots at least 5 cm long.
- Step 2: Cut the keiki from the mother cane with a sterile blade, keeping roots intact.
- Step 3: Mount on a small piece of driftwood or pot in coarse orchid bark mix.
- Step 4: Keep humid and in bright indirect light — mist daily for the first month.
- Step 5: For division, split clumps ensuring each division has at least 3-4 healthy canes.
Care Guide
Sunlight
Bright indirect light to filtered sun (50-70% shade cloth ideal; morning sun with afternoon shade works well). Position your dendrobium orchid where it receives the right amount of light for healthy growth in Philippine conditions.
Water
Water thoroughly when medium is nearly dry — typically every 2-3 days in dry season, less during rainy season. Allow roots to dry slightly between waterings. Avoid standing water in pots. Adjust frequency during the Philippine rainy season when humidity is higher and soil stays moist longer.
Temperature & Humidity
Ideal temperature range: 22-32°C (most hybrids thrive in Philippine lowland temperatures; some species prefer highland coolness). High humidity (60-80%) — natural Philippine humidity is ideal. Mist daily during dry season. The warm, humid Philippine climate is well-suited for growing dendrobium orchid outdoors or indoors.
Fertilizer
Apply diluted orchid fertilizer (20-20-20) at half strength every 1-2 weeks during active growth. Reduce to monthly during rest period. Foliar feeding is also effective.
Pruning
Do not cut old canes unless completely dried — they store nutrients and may produce keikis or flowers again. Remove only spent flower spikes.
Toxicity & Safety
Non-toxic. Safe around children and pets. Some species have edible flowers used in Asian cuisine.
Common Problems & Solutions
Wrinkled or shriveled pseudobulbs
Cause: Underwatering or root rot preventing water uptake
Solution: Check roots — healthy roots are white/green with green tips. If roots are rotten (brown/mushy), remove and repot in fresh bark. If roots are healthy, increase watering frequency.
No flowers for more than a year
Cause: Insufficient light, lack of temperature variation, or too much nitrogen
Solution: Increase light exposure. Ensure slight night-day temperature difference. Switch to a bloom-boosting fertilizer (10-30-20) during pre-bloom period.
Black spots on leaves
Cause: Bacterial or fungal infection, often from overhead watering in poor ventilation
Solution: Cut away affected areas with sterile scissors. Apply cinnamon powder to wounds. Improve air circulation and avoid wetting leaves in the evening.
Scale insects on canes
Cause: Sheltered conditions with poor air flow
Solution: Wipe off with rubbing alcohol on cotton buds. Spray with neem oil. Isolate affected plant from collection.
