some of my outdoor cymbidium orchid flowers are browning out and dying.what could be the problem, this normal?
Light.
Fairly strong light at 2500-3000 ft candles is good for these plants. If they are grown in a conservatory or greenhouse then 50%-60% shading is needed during the summer months to prevent leaf burn and overheating. If you are growing them outside in summer, early morning sun is ideal, but do provide some shade against the strongest sunlight.
Flush the compost through with pure rainwater at every fourth watering. Reduce the fertiliser strength to half the recommended dose through Autumn and Winter.
