How to Care for Goeppertia dressleri 'Helen Kennedy' Indoors

Light: Needs bright, indirect light. Avoid direct sun, which can bleach or scorch the leaves. Can tolerate slightly lower light but grows slower.
Watering: Keep the soil lightly moist at all times. Water once the top 2–3 cm feels dry. Never let the root zone sit in stagnant water.
Humidity: Requires ≥60% humidity. Ideal range is 70–80%. Mist daily or use a pebble tray or humidifier, especially in winter heating season.
Temperature: Performs best between 18–24°C. Avoid cold drafts, dry air, or sudden drops below 15°C.
Soil: Use a loose, airy, peat-free mix. Combine quality potting soil with perlite, coco coir, and fine orchid bark.
Feeding: Apply a balanced liquid fertilizer every 4–6 weeks. Avoid overfeeding, which may cause leaf edge burn.


Problems You Might Encounter with Goeppertia dressleri 'Helen Kennedy'

Browning Edges: Most often caused by dry air or salts in tap water. Use distilled or filtered water and increase humidity.

Spider Mites: A common pest in dry air. Increase humidity and treat with neem oil or insecticidal soap.


Additional Plant Tips for Long-Term Success

Potting: Use breathable pots with drainage holes to protect the sensitive rhizomes from rot.
