Reasons and Solutions for Yellowing Leaves in Cymbidium ensifolium

1. Unsuitable soil

Cause: Cymbidium ensifolium has fleshy roots and a well-developed root system, requiring soil with good permeability. If the soil is too clayey, it will affect root growth and prevent the roots from transporting nutrients.

Solution: If yellowing leaves are caused by unsuitable soil, repot promptly and choose a specialized potting mix, which generally has suitable permeability and pH.

2. Improper lighting

Cause: Cymbidium ensifolium prefers light. Keeping it in shade for a long time will cause a lack of chlorophyll and yellowing leaves, but under strong direct sunlight, the leaves will be scorched and turn yellow.

Solution: During care, place the plant in a bright spot. In summer, provide appropriate shade to avoid strong sunlight.

The above are the cultivation methods for Cymbidium ensifolium and the solutions for yellowing leaves. We hope your Cymbidium ensifolium will grow more vigorously!

Causes of Yellowing Leaves in Cymbidium ensifolium and What to Do About It

Cymbidium ensifolium is one of the most popular flowering plants for home cultivation. If your Cymbidium ensifolium shows yellowing leaves, take a look at the causes and solutions for yellowing leaves in Cymbidium ensifolium!

Causes of yellowing leaves in Cymbidium ensifolium:

Unsuitable soil

Cymbidium ensifolium has fleshy roots that are well-developed and thick, so it has relatively high requirements for soil permeability. If planted in heavy clayey soil, root growth will be affected, interrupting the nutrient transport channel between the roots and leaves.

Improper lighting

Cymbidium ensifolium is an orchid variety that relatively prefers light. If kept in shade for a long time, the plant will lack photosynthesis, leading to reduced chlorophyll and yellowing leaves; if exposed to sunlight for a long time, the light is too strong and the plant is easily scorched, and the leaves lose their vitality.

Improper fertilisation

Excess nitrogen fertiliser. Everyone knows that nitrogen fertiliser can promote leaf growth, but the roots of Cymbidium ensifolium have root nodules that have a certain ability to aggregate nitrogen. If the fertiliser applied during a certain period has a high nitrogen content, it will cause fertiliser burn and yellowing leaves.

Pests and diseases

Root rot is one of the causes of yellowing leaves. If the roots and stems rot, the leaves above ground will inevitably grow poorly, turning yellow or even withering.

In addition, scale insect damage can also cause yellowing leaves. When branches are covered with insects, the plant's photosynthesis is affected and the branches slowly wither.

What to do about yellowing leaves in Cymbidium ensifolium:

Repot and adjust light

If unsuitable soil is found, repot immediately. You can choose a professional orchid growing medium, which has suitable permeability and pH. Try not to use soil dug directly from outside, as such soil does not have good aeration.

In daily care, place the orchid pot in a bright place. In spring and winter, it can receive full-day sunlight without shading. In summer and autumn, avoid the midday sun and provide appropriate shade.

Apply light fertiliser frequently

The biggest taboo for orchids is heavy fertiliser. Gardeners who do not know how to fertilise must learn well. Apply fertiliser when it is time to do so; whether fertilising is done correctly or not affects the growth of Cymbidium ensifolium. Persist with light fertiliser applied frequently and do not be lazy, so that Cymbidium ensifolium can grow robustly.

Prevent and control pests and diseases

If the plant is found to be affected by pests or diseases, treat it promptly. When roots are rotting, remove the plant from the pot, clean away the rotten parts, soak in disinfectant for 20~30 minutes, let it dry, and replant.

If scale insects appear on the leaves, spray pesticide promptly; omethoate 1000x solution can be used.

What to do about yellowing leaves in Cymbidium ensifolium

Cymbidium ensifolium prefers a warm, humid and semi-shaded environment, and has poor cold tolerance. The overwintering temperature should not be lower than 3°C. It fears strong direct sunlight and cannot tolerate waterlogging or drought. It is suitable for growing in loose, fertile, well-drained leaf mould. The flowers of Cymbidium ensifolium are elegant and beautiful, and with emerald-green leaves they look like a graceful beauty. But when you grow your own Cymbidium ensifolium, the leaves turn yellow over time.
