What to do when Cymbidium leaves turn yellow? Causes and solutions

Flowers & Gardening 0 views
There are four solutions for yellowing Cymbidium leaves: if it is due to too low temperature, raise the temperature to 18-23°C, and to 5-10°C in winter; if it is due to exposure to the sun, place it where there is no direct sunlight; if it is due to overwatering, reduce the frequency of watering and place it in a ventilated, dry spot; if it is due to improper fertilizer use, switch to fermented, decomposed cake fertilizer.

1. Raise the temperature

Cause: A too-low temperature environment makes the Cymbidium grow poorly, resulting in yellowing leaves.

Solution: Place the plant in a bright, ventilated spot at 18-23°C, and keep it at 5-10°C in winter.

2. Provide appropriate shade

Cause: Cymbidium grows vigorously in sunlight, but it cannot be exposed to direct sunlight, otherwise the leaves will turn yellow.

Solution: At noon, place the plant away from windowsills and other spots with strong light; at other times, place it in a warm, bright place to ensure a certain amount of light.

3. Dry out the potting soil

Cause: Cymbidium is suited to growing in relatively dry soil; if the potting soil stays too wet for a long time, the leaves will turn yellow.

Solution: Do not water too frequently; water thoroughly each time; water again only when the soil is no longer moist, and at the same time place the plant in a ventilated, dry spot.

4. Use decomposed fertilizer

Cause: Adding unfermented cake fertilizer or pure phosphorus fertilizer when fertilizing causes the leaves to turn yellow.

Solution: Use decomposed fertilizer to prevent "over-fertilizing" from burning the plant's roots.
