Cambria Orchid | No 662

Lighting
Bright, indirect light is ideal for Cambria orchids, but they can tolerate more light than Phalaenopsis. Place near an east or south-facing window for optimal growth. While direct sunlight can cause sunburn, Cambrias can handle up to 2-3 hours of gentle morning sun, which is more than most Phalaenopsis can tolerate.

Watering
Water Cambria orchids more frequently than Phalaenopsis, typically every 4-7 days depending on the environment. In summer, it may be as often as every 3-4 days, while in winter, it can be less frequent (up to 7-10 days). Use lukewarm water and ensure the potting medium is moist but not waterlogged. As with Phalaenopsis, avoid getting water on the crown to prevent rot.

Humidity
Maintain a humid environment for Cambrias, ideally between 40% and 70% relative humidity. While they prefer high humidity like Phalaenopsis, Cambrias can tolerate slightly lower levels. Use a tray with pebbles and water to create a humid microclimate without sitting the pot in water.

Temperature
Cambrias prefer cooler temperatures than Phalaenopsis. Daytime temperatures should be between 18°C and 24°C. A more significant drop in temperature at night is beneficial for Cambrias; aim for around 13°C on cooler nights. This temperature fluctuation (about 6-8°C difference) can help induce blooming more readily than in Phalaenopsis.

Fertilisation
Use a balanced fertiliser (such as 20-20-20) for Cambrias, applied more frequently than for Phalaenopsis during the growing season. Fertilise every 1-2 weeks with a diluted solution. Reduce frequency to monthly during winter or when the plant is not actively growing.

Repotting
Repot Cambria orchids every 1-2 years or when the potting medium breaks down, similar to Phalaenopsis. Use a well-draining orchid potting mix, trim any dead roots, and choose a pot slightly larger than the root system. Cambrias may need repotting slightly more frequently than Phalaenopsis due to their faster growth rate.
