4 Reasons Your Orchids’ Leaves Are Turning Yellow



Are the leaves on your Orchid turning yellow? Before you panic, you should know that this isn’t really a cause for alarm. Yellowing leaves is normal and even natural for older leaves. Gradually, they will drop off. Here are some important information you need to know about yellowing leaves on your Phalaenopsis: 

It’s Getting Too Much Light

If you notice that the leaves are turning yellow, but they’re plump and firm, it could be because they’re over-exposed to light that is washing out the color. This is normal for this type of plant. So, the best way to solve this is to put the orchid in a place that has enough indirect sunlight. If you choose to place it on a windowsill, make sure it’s a north- or west-facing window. 

It’s Not Getting the Right Temperature

If it’s not light exposure, check the temperature in the area. If it’s too low, it can cause the leaves to turn yellow. That’s why it’s crucial you maintain the right temperature level, which is between 65 and 8-0 degrees Fahrenheit during the day, and at night, it should be between 60 and 70 degrees Fahrenheit. Another thing is to keep the plant away from open windows or AC vents. 

It’s Not Getting Enough Water

Aside from yellowing leaves, if you notice they are wrinkled and listless, it’s likely the plant is not getting enough water. On the other hand, if the leaves are not wrinkled, then the yellowing leaves may be due to overwatering. In this case, check the roots because too much water can lead to root rot. 

Make sure to only water the plant when the top one inch of the potting medium is dry, and you notice the roots are white. Furthermore, have enough potholes for proper drainage. 

If your plant has root rot, but there are still a few healthy green roots, you can trim the rotted roots and repot the plant in a new pot. In the first week in a new pot, mist the leaves only. 

Another way to avoid overwatering is to place three ice cubes once a week on your plant. Doing so will allow the roots to soak the water slowly.

It Has a Disease

Another reason your plant’s leaves are turning yellow is because of fungal or bacterial diseases. When this happens, the yellowing may start on the bottom of the leaves, and eventually, they will turn black and affect both sides of the leaves. 

If you notice a nasty odor, then it could be a bacterial infection. You can solve this by separating the orchid from other plants to prevent the disease from spreading and then remove the affected area of the plant. Spray a fungicide to finish it up.
