Over-Watering and Under-Watering
Common causes of orchid leaves turning yellow include over-watering and under-watering your plant. Let’s talk about both of these plant care concerns in detail, how they can lead to yellowing orchid leaves and what can be done to return your plant to a happy, healthy and flourishing state.
Orchid Leaves Turning Yellow? Over-Watering
Over-watering can lead to orchid leaves turning yellow. Orchids are susceptible to root rot if they are consistently kept in soggy or waterlogged conditions by frequent over-watering. In turn, this can also lead to impaired nutrient absorption (another potential cause of yellowing orchid leaves that we’ll also discuss in further detail soon). Over-watering can lead to these stressors impacting the plant, resulting both in yellowing leaves and general, overall decline.
There are three things you can do to address the over-watering of your orchid plant. First, be sure to allow the potting medium to partially dry out between individual watering sessions. Second, ensure that your orchid has proper and adequate drainage. And third, always avoid leaving the orchid sitting in standing water for any length of time.
Orchid Leaves Turning Yellow? Under-Watering
On the other hand, under-watering can also lead to orchid leaves turning yellow. Under-watering deprives orchids of sufficient hydration, causing stress and (you guessed it) leaf yellowing as well. As the plant becomes stressed and dehydrated in this way, you may start to notice yellow leaves. But don’t worry, there’s an easy solution to address this too! Regularly check the potting medium and water the orchid when the top inch feels obviously dry to the touch. Striking the right balance in watering will promote a healthier orchid with vibrant foliage.
Ice Cube Watering Method for Orchids
One way to strike the right balance in watering your orchid is with the ice cube watering method. The ice cube method for watering orchids is a popular approach that involves placing a few ice cubes on the potting medium instead of directly pouring water onto the plant. This method is important because it provides a controlled and measured amount of water, preventing over-watering, which is a common issue for orchids (and in turn, a common cause of orchid leaves turning yellow). The slow-melting ice cubes allow the water to be gradually absorbed by the roots, mimicking the slow watering patterns orchids receive in their natural habitat. As a result, the ice cube method helps maintain proper moisture levels and prevents root rot, promoting healthier orchid growth and reducing the risk of yellowing leaves due to water-related stress.

Orchid Leaves Turning Yellow? Insufficient Light
Another potential cause of orchid leaves turning yellow is insufficient light. Orchids can be notoriously picky when it comes to their light needs. Orchids require a delicate balance of light and shade to thrive, and without the right conditions, they may struggle to produce healthy foliage. While too much can cause damage to leaves and flowers, too little can leave your plant weak and struggling.
That being said, insufficient light is a very common cause of yellowing orchid leaves, and can quickly lead to a host of related issues including leggy growth and poor health overall. If your orchid is not getting enough light, its leaves can easily turn yellow, and the plant itself may become weak. But the good news is that there are steps you can take to help your orchid get the right amount of light . . .
To help your orchid thrive, consider moving it to a brighter location near a window (or on a windowsill) with indirect sunlight. However, be careful not to expose the plant to direct sunlight, as this can scorch the leaves and damage the delicate flowers. If this ideal lighting placement isn’t possible, supplementing with artificial grow lights can be a great option. Supplementing your orchid’s light with artificial grow lights, can provide the necessary spectrum of light for optimal growth that your plant needs.
By ensuring your orchid gets the right amount of light, you’ll not only prevent yellowing leaves but also encourage stunning blooms in the future. With the right amount of light, your orchid can put on a dazzling display of vibrant leaves and stunning blooms. Next, let’s explore another common cause of orchid issues, that of pest infestation.
Orchid Leaves Turning Yellow? Pest Infestation
Another common cause of orchid leaves turning yellow is pest infestation. Pests like spider mites, mealybugs, and scale insects can easily latch onto your orchid and suck the sap from the leaves, leaving them discolored and weakened. If you notice small brown spots or webs on the undersides of your orchid leaves, it’s likely you have a pest infestation. To remedy the issue, use a gentle soap and water solution to clean the leaves and stems of your orchid, ensuring that every nook and cranny is thoroughly treated. Horticultural oil can also be effective in preventing future infestations.
By keeping a watchful eye on your orchid and addressing pest issues promptly, you’ll not only prevent yellowing leaves but also promote a healthy and thriving plant.
Improper fertilization is another factor that can contribute to orchid leaves turning yellow. Let’s take a closer look at that next.
Improper Fertilization & Nutrient Deficiency
Improper fertilizer and nutrient deficiency (or both) can also be causes of orchid leaves turning yellow. While fertilization is essential for maintaining healthy and blooming orchids, applying too much or the wrong type of fertilizer can lead to yellowing leaves. Orchids require a specific balance of nutrients to thrive, and over-fertilization can cause a buildup of salts in the soil, which can prevent the plant from absorbing the necessary nutrients properly.
What is the best solution? To prevent yellowing leaves due to improper fertilization, it’s important to use a well-balanced fertilizer designed specifically for orchids – and, for your specific type of orchid too. Avoid using regular houseplant fertilizers, which can be too potent for orchids and can sometimes cause further damage to your plant. Additionally, make sure to follow the specific instructions for your particular fertilizer, including the recommended frequency of use and dosage.
Also remember that less is often more when it comes to orchid fertilization. When in doubt, it’s better to under-fertilize than over-fertilize. A good rule of thumb is to fertilize your orchid with a weak solution every two weeks during the growing season, which is typically from spring to fall. During the winter months, reduce or stop fertilization altogether.
By giving your orchid the proper fertilization it needs, you’ll not only prevent yellowing leaves, but also encourage healthy growth and blooming.
Orchid Leaves Turning Yellow? Temperature Stress
In addition to the above common reasons for orchid leaves turning yellow, temperature stress can sometimes be a cause of yellowing orchid leaves too. Drastic temperature fluctuations, especially exposure to cold drafts or low temperatures, can lead to a stressed, unhealthy plant with yellowing leaves. The way to resolve this is to keep your orchid in a stable environment with appropriate temperature conditions for its species and preferences.
Orchid Leaves Turning Yellow? Natural Aging
Lastly, natural aging is another common cause of orchid leaves turning yellow. As orchid plants and their leaves age, they may naturally turn yellow and then drop off. You may often then possibly see new leaf growth afterwards, as the plant sheds it’s older leaves. But before this, the leaves will first begin to turn yellow and then gradually fall from the plant. A solution is to regularly trim yellowing or spent leaves as they occur, to redirect the plant’s energy to healthier, new growth.
