- Light:
- Most epiphytes prefer bright, indirect light. Direct sunlight can scorch their leaves.
- East-facing or bright north-facing windows are often ideal. West or south-facing windows may require shading, especially during the hottest parts of the day.
- Observe your plant for signs of too much or too little light. Leggy growth or lack of flowering can indicate insufficient light, while scorched or yellowing leaves might mean too much direct sun.
- Watering:
Their low-maintenance nature and watering frequency is another key factor in their popularity. Adapted to survive in environments where water and nutrients can be sporadic, many epiphytes are more forgiving of occasional neglect than their soil-dwelling counterparts. Their specialized leaves and roots are designed to absorb and retain moisture from the air, reducing the frequency of watering. While their specific needs vary by species, many thrive on a simple routine of regular misting or a periodic soak.
- Method is key: Since they don't grow in soil, you'll need to water them differently. The most common methods are:
o Soaking: For air plants (Tillandsia) and some orchids, submerge the entire plant (or just the leafy parts for mounted plants) in room-temperature water for 15-60 minutes every 1-2 weeks, depending on humidity and temperature. Allow them to dry completely upside down afterward to prevent water from sitting in crevices and causing rot.
o Misting: For many epiphytes, especially orchids and some bromeliads, regular misting can provide sufficient moisture, especially in humid environments. Mist several times a week, ensuring the leaves are thoroughly wetted.
o Watering the Cup: For bromeliads with a central cup, keep the cup filled with fresh, clean water, changing it every few weeks to prevent stagnation.
o Ice cubes: In the green industry, you can see watering instruction from Green circle growers co. for Orchid by putting ice cubes on top of soil.
o However, you can spray water and periodically air plant fertilizer which is mix of 1-1-4 NPK or 2.5-0-2.5 NPK.
- Water Quality: Use rainwater, distilled water, or tap water that has been left out for 24 hours to allow chlorine to evaporate. Avoid softened water, as it can contain salts that are harmful to epiphytes.
- Frequency:Watering frequency depends on your environment. Higher temperatures and lower humidity will require more frequent watering. Observe your plant for signs of dehydration, such as wrinkled or drooping leaves.
- Air Circulation:
- Good airflow is crucial for epiphytes to dry out properly after watering and prevent rot.
- Avoid placing them in stagnant, enclosed spaces. Open windows occasionally or use a small fan to provide gentle air movement.
- Humidity:
- Most epiphytes thrive in moderate to high humidity (40-70%).
- Dry indoor air, especially during winter with heating systems, can be detrimental.Increase humidity by:
o Using a humidifier.
o Placing plants on a pebble tray filled with water (ensure the pot or mount isn't sitting directly in the water).
o Grouping plants together, as they create a microclimate of higher humidity.
o Misting regularly.
- Fertilizing:
- Epiphytes are not heavy feeders. Fertilize sparingly, usually during their active growing season (spring and summer).
- Use a diluted, balanced liquid fertilizer specifically formulated for orchids or bromeliads. Dilute it to ¼ or ½ of the recommended strength.
- Apply fertilizer through misting or by adding it to the soaking water. Fertilize every 2-4 weeks during the growing season. Reduce or stop fertilizing during the dormant season (fall and winter).
- Mounting and Support:
- Since they don't grow in soil, epiphytes are often mounted on natural materials like cork bark, driftwood, or tree fern plaques.
- Use fishing line, plant wire, or non-toxic glue to secure the plant. Avoid burying the base of the plant or covering it with moss unless it's part of a specific mounting technique for moisture retention.
- Ensure the mount allows for good airflow around the plant's base and roots.
- Temperature:
- Most epiphytes prefer temperatures between 60-80°F (15-27°C). Avoid extreme temperature fluctuations and drafts.
- Repotting/Remounting:
- Epiphytes don't need traditional repotting. If a mounted plant outgrows its mount or the mount begins to deteriorate, gently remove the plant and secure it to a larger or new mount. This is best done during the active growing season.
