Phalaenopsis
Phalaenopsis orchids — often called moth orchids — are the embodiment of quiet luxury in the plant world. Their arching sprays of blooms can last for months, bringing a sense of calm refinement to any interior.
Cymbidiums
known for their tall, impressive flower spikes filled with long-lasting blooms. They flower in winter through early spring, adding bold color and life to the garden when most plants are still resting.
Dendrobium
Diverse. Resilient. Endlessly rewarding.
Vast and varied family, ranging from tropical warmth-lovers to cool-growing seasonal bloomers. What they share is a reputation for resilience and spectacular floral displays
Zygopetalum
Lush foliage. Dramatic color. A fragrance worth leaning in for.
Zygopetalum orchids are treasured for their richly colored blooms and distinctive perfume — often described as sweet and spicy, especially in the morning hours. Their handsome foliage makes them attractive even out of bloom, giving them year-round presence.
​
Light
Phalaenopsis prefer bright, indirect light. Think of the gentle glow near an east-facing window or a softly filtered southern exposure. Deep green leaves suggest insufficient light, while a lively yellow-green tone signals ideal conditions.
Water
Water every 7–10 days, allowing the growing medium to approach dryness between waterings. Roots should never sit in water; these orchids appreciate moisture paired with excellent drainage.
Temperature
Comfortable in 65–80°F, Phalaenopsis thrive in the same temperatures we do. A slight drop at night can encourage blooming, mimicking their natural environment.
Humidity
They favor 40–60% humidity. In drier homes, a humidity tray or discreet humidifier creates a more hospitable atmosphere.
Feeding
Use a balanced orchid fertilizer at quarter strength every 2–3 weeks during active growth. Consistency, not excess, is the secret.
After Bloom
When flowering ends, trim the spike just above a node for a possible secondary bloom, or cut it to the base to allow the plant to rest and gather strength for the next show.

Light
Cymbidiums like shaded bright light and can tolerate gentle morning sun. Strong light is essential for flowering, giving their foliage a vibrant, grassy green tone.
Water
During active growth, water thoroughly and regularly, keeping the media evenly moist but never waterlogged. Once a week should do the trick. After blooming, reduce watering slightly as growth slows.
Temperature
These orchids prefer cooler nights, particularly in late summer and fall. Evening temperatures in the 40s–50s°F help initiate flower spikes — a natural cue they rely on.
Humidity & Airflow
Fresh air and circulation are vital. Cymbidiums are well-suited to life outdoors in the Bay Area’s mild climate, where natural humidity and temperature shifts do them good.
Feeding
Feed with a nitrogen-rich fertilizer in spring and summer to support leafy growth, then transition to a bloom-focused formula by late summer.
Repotting
Repot every 2–3 years after flowering. They appreciate being slightly root-bound, but fresh media keeps plants vigorous and blooming reliably.
.
Light
Most Dendrobiums prefer bright light, with some gentle direct sun. Strong light encourages sturdy growth and reliable flowering.
Water
Water regularly during active growth, allowing the media to approach dryness between waterings. Good drainage is essential.
Temperature
wide popular varieties thrive between 60–85°F, though some benefit from cooler nights as part of their seasonal cycle.
Humidity
Aim for 50–70% humidity with good air circulation to keep plants vigorous and disease-free.
Feeding
Fertilize every 2–3 weeks during the growing season, reducing feeding as growth slows.
Seasonal Rest (For Some Types)
Certain Dendrobiums, particularly nobile types, require a cooler, drier winter rest to initiate flowering. This natural pause is key to their spectacular spring display.
Light
Zygopetalums prefer bright, indirect light. A bright east window or filtered southern exposure is ideal. Leaves should be medium green; yellowing suggests too much light, while very dark green can mean too little.
Water
These orchids enjoy consistent moisture and should not dry out completely. Water thoroughly when the top of the media begins to feel slightly dry. Good drainage is essential — they like moisture, but never soggy roots.
Temperature
Zygopetalums appreciate intermediate to cool temperatures, ideally 60–75°F during the day with slightly cooler nights. They are more tolerant of cool conditions than many tropical orchids.
Humidity
Aim for 50–70% humidity with good air movement. They respond beautifully to stable moisture in the air, especially during active growth.
Potting Media
A fine to medium orchid bark mix with added moisture-retentive components (like sphagnum moss or perlite) works well, as their roots prefer slightly more moisture than many orchids.
Feeding
Feed with a balanced orchid fertilizer at half strength every 2–3 weeks during active growth. Flush the pot with plain water monthly to prevent salt buildup.
Blooming Habit
Zygopetalums often bloom in fall through spring, sending up fragrant spikes from the base of new growths. Healthy plants with strong pseudobulbs are the key to repeat flowering.
Repotting
Repot every 1–2 years, ideally when new growth begins. Fresh media supports their moisture needs and keeps roots healthy.
