So, what could potentially be stealing the beauty of these magnificent climbers? The answer might be complex but uncovering the underlying causes can be a fascinating journey of discovery into the intimate world of plant health.
Why Are Morning Glory Leaves Turning Yellow?
1. Nutrient deficiency

Morning glory leaves may turn yellow due to a nutrient deficiency, especially lack of nitrogen. Nitrogen is important for leaf development and overall plant growth. In absence of sufficient nitrogen, the plants can’t produce enough chlorophyll which leads to yellowing of the leaves, this condition is known as chlorosis.
Solution: Regular fertilizing can correct a nitrogen deficiency. Use a balanced plant food that has a high first number, such as 24-8-16 or similar. While feeding, make sure to follow the manufacturer’s instruction on how much to apply and when. Water thoroughly after applying fertilizer. This will provide the necessary nutrients to the plant, causing the new leaves to be green and healthy.
Caution: Over-fertilization can lead to salt build-up which can harm the plant. So, it is important to avoid over-doing it. Also, ensure your morning glory is getting enough light as insufficient light can also cause yellowing of leaves.
2. Overwatering

The issue of overwatering can cause morning glory leaves to turn yellow. Overwatering results in water logging of the soil and poor aeration. Essentially, the roots of the plant can’t breathe, and it takes its toll on the overall plant health, leading to leaf yellowing as one visible symptom.
To counteract this, try to keep the soil somewhat dry. Water the plant only when the topsoil feels dry to the touch. Proper drainage is also crucial, so make sure the plant pot or garden bed has good drainage to prevent water accumulation. Regulated watering and good drainage practices are key to maintaining the health of your morning glory plant.
Additionally, morning glories thrive in full sun to partial shade. So, provide them an environment with adequate sunlight and pertinent shade to enhance their growth and keep leaves vibrant.
3. Lack of sunlight

Morning glory plants thrive in full sun conditions, and a lack of it can disrupt their overall health, causing their leaves to turn yellow. Insufficient sunlight results in the plant being unable to carry out photosynthesis effectively, which is vital for the plant’s food production and overall growth. This disruption in the plant’s food production process often reflects in the yellowing of the leaves.
To remedy this, you can consider moving your morning glory to a spot where it can receive at least six hours of sunlight a day. If it’s potted, it’s a relatively easier process. However, if the plant is rooted in your garden, try thinning out any overhead foliage that may be blocking the sunlight. If outdoor sunlight isn’t possible, you can supplement this with an indoor plant light. Ensuring the plant is getting adequate light will aid in photosynthesis and the overall health of the plant, reversing the process of the leaves turning yellow.
4. Pest infestation

The yellowing of morning glory leaves may be due to pest infestation. Certain pests such as spider mites, aphids, or thrips can cause significant damage to the plant, affecting its overall health and vitality. These bugs usually feed on the sap within the leaves, effectively draining them of essential nutrients. The result of this parasitic relationship is typically a yellow or pallid appearance in leaves, as well as potential growth stunting.
To remedy pest-related yellowing in morning glory leaves, you should first identify the specific pest responsible for the damage. Once you recognise the pest, you can treat your morning glory plant with the appropriate pesticide or insecticidal soap. Using targeted doses of neem oil has also been proven effective in battling pest infestations. Though remember, it’s important to employ these treatments with the right balance to not overwhelm or further damage the plant.
5. Disease or fungus

When your Morning Glory leaves are turning yellow, it can be due to a disease or fungus. Diseases and fungi can prevent the plant from effectively photosynthesizing, causing its leaves to yellow. Some common diseases and fungi that affect Morning Glories include root rot, leaf spot, and mildew. These diseases not only yellow the leaves but can also cause them to wilt or fall off completely.
To treat the plant, first, you must identify the type of disease or fungus present. Fungal diseases such as mildew can often be treated with a fungicide. However, for bacterial or viral diseases, you might need specific plant antibiotics which are available in most garden stores. Another crucial step is to remove and destroy any infected parts of the plant to prevent the disease or fungus from spreading. Moreover, try to improve the plants’ conditions. Ensure the plant has well-drained soil, isn’t overcrowded, and receives the right amount of sunlight and water. This will boost the plant’s overall health and aid it in resisting and recovering from infections.
6. pH imbalance in the soil

| Solution | Adjust soil pH to correct imbalance for healthy morning glory leaves. |
Morning Glory leaves turning yellow can be a direct result of a pH imbalance in the soil. The range of soil pH has a tremendous impact on plant growth as it affects the availability of essential nutrients. When the soil’s pH is off, nutrients such as iron, manganese and zinc can become less available to the plant, causing deficiencies leading to yellowing leaves.
Solving this issue involves amending the soil to correct its pH level. Test the soil first to determine its current pH. If it is too acidic (below 6.0), you can add lime. If it is too alkaline (above 7.0), you may want to add sulfur or a fertilizer specifically designed for acid-loving plants. Additionally, providing a balanced fertilizer can ensure the Morning Glory is getting enough of the aforementioned micronutrients. Remember, changes in soil pH happen gradually, so it might take a few weeks to notice improvement in the plant’s health.
7. Environmental stress (such as extreme temperatures or drought)

Morning Glory leaves may turn yellow due to inadequate watering. Water is an essential resource for all plants. For Morning Glories, improper watering– either excessive or insufficient – can lead to yellowing leaves.
Excess water could suffocate the plant’s roots, while inadequate water could dry out the plant. Both these extremes stress the plant and could lead to leaf discoloration, mainly turning them yellow.
To rectify this, it’s crucial to establish a balanced watering routine. The soil should be kept moist, but not waterlogged. If you’re overwatering, cut back and allow the soil to dry out before watering again. Conversely, if you’re underwatering, you’ll need to increase the frequency or amount.
Also, ensure you water the plants early in the morning or late in the evening when temperatures are cooler. This minimizes water loss through evaporation.
