Why does an orchid have yellow leaves?

Orchids are plants that can surprise with their beauty. However, they can cause problems, especially when the leaves start to yellow. Overwatering is one of the main causes of this issue. Orchids need a specific amount of water—too much can lead to root rot, which ultimately affects the condition of the leaves. It's crucial to adjust watering according to the season and the location of the plant.

This problem may also be caused by inappropriate soil. Orchids grow best in permeable soil that allows proper airflow around the roots. Soil that is too dense retains water and promotes rotting. Therefore, using special orchid soil, which often contains a mix of bark, perlite, and charcoal, is recommended.

Orchids thrive in bright locations, but too much sunlight can lead to leaf burn. It's recommended to place them in a location with plenty of diffused light, such as on window sills with eastern or northern exposure. If the plant is in too dark a location, the orchid's leaves may begin to yellow and break.

Yellowing leaves can also indicate fertilizing mistakes. Discoloration of the leaves may signal a deficiency of nutrients like nitrogen or iron. To prevent deficiencies, it's best to fertilize orchids regularly from April to September.

However, discoloring orchid leaves do not always mean disease or care errors. Orchid leaves can also yellow as a result of the natural aging process. In this case, they should be gently removed.

How to prevent orchid leaves from yellowing?

To avoid problems with yellowing leaves, start by choosing the right pot and soil. Orchid pots should have drainage holes to ensure effective water removal.

Pay attention to how you water. Ideally, orchids should be watered once a week, and during the winter season, when the plant is resting, even less frequently. It's important to monitor the moisture level of the soil and water the plants when it's dry to a depth of about 1 inch. The water should be soft, preferably filtered or distilled, and it's a good idea to submerge the pot in it for 15 minutes to thoroughly hydrate the roots. Avoid overwatering the orchid, as it can lead to root rot.

Ensure the plant receives the right amount of light and fertilize systematically during the period of the greatest nutrient need. Do not place the plant where it will be exposed to temperature fluctuations or high temperatures (e.g., near a heater). This can not only lead to yellowing leaves but also inhibit growth and flowering.
