Common Causes of Hydrangea Leaves Turning Brown
Hydrangea leaves can turn brown due to several common causes, such as transplant shock, fertilizer burn, insect infestation, fungal diseases, insufficient watering, excessive sun exposure, and wind damage.
Transplant Shock
Plants like hydrangeas can get upset during a move. This is called transplant shock. It can turn the leaves brown. Transplant shock happens when a plant moves to a new place that feels very different from its old home.
It causes the flowers and leaves to wilt or droop down. The color of the leaf may change too, turning yellow or brown instead of green. To avoid this, make sure you water your hydrangea well and give it just enough light without making it too hot or cold.
Use good soil for your plant and don’t feed it more than needed.
Fertilizer Burn
Fertilizer burn can turn your hydrangea leaves brown. This happens when you feed the plant too much. The fertilizer is like food for the plant. But, too much food can hurt it. The chemicals in the fertilizer can cause a burn.
This burn will make the leaves go brown.
Be careful when using fertilizers that have lots of nitrogen. These types of fertilizers might increase the risk of burns on your hydrangea’s leaves. If this happens, you will see your hydrangea’s leaves wilt and turn brown because they got burned by fertilizer.
Insect Infestation
Bugs can cause big problems for your hydrangeas. Aphids, spider mites, and beetles love these plants. They make the leaves turn brown. Look at your plants often to spot bugs early on.
Treat any bug problem right away to keep your hydrangeas healthy.
Fungal Diseases
Fungal diseases like Anthracnose and Cercospora leaf spot can cause hydrangea leaves to turn brown. Excessive watering can lead to leaf spot fungus, resulting in brown spots on the leaves.
Anthracnose causes large brown spots with lighter centers, while Cercospora appears as circular purple or brown spots on the bottom of the plant. Proper identification and treatment of these fungal diseases are important for keeping your hydrangea plants healthy and looking their best.
Insufficient Watering
Insufficient watering is a common reason why hydrangea leaves turn brown. When you don’t give your hydrangeas enough water, their leaves can start to wilt and become crispy. Underwatering means the plants aren’t getting enough moisture, which causes the leaves to dry out and turn brown.
It’s important to make sure you water your hydrangeas regularly and deeply, especially during hot weather or when there hasn’t been much rain. By giving them the right amount of water, you can help keep their leaves healthy and prevent them from turning brown.
Excessive Sun Exposure
Excessive sun exposure is a common reason why hydrangea leaves turn brown. Hydrangeas, especially Mophead hydrangeas, are sensitive to too much sunlight. When these plants are exposed to the hot sun for long periods of time without enough water, their leaves can become damaged and turn brown.
This excessive exposure to sunlight can cause the leaves to dry out and even get sunburned. So if you notice your hydrangea leaves turning brown, it’s important to provide them with some shade or protection from the intense sunlight.
Wind Damage
Excessive wind can harm your hydrangeas by making the leaves dry out and turn brown. This is one of the most common causes of brown leaves in hydrangeas. When there’s strong wind, it can stop the roots from getting enough water, which makes the leaves turn brown.
To prevent this, you need to protect your hydrangeas from strong winds so that their leaves stay healthy and green.
How to Fix Brown Hydrangea Leaves
To fix brown hydrangea leaves, properly water the plants, adjust fertilization practices, treat insect infestations, address fungal diseases, provide shade or protection from excessive sun exposure, and protect the plants from strong winds.
Read on to learn more about these effective solutions!
Properly water the plants
To keep your hydrangea leaves from turning brown, it’s crucial to water them properly. Hydrangeas need consistently moist soil to stay healthy and avoid wilting and browning. Make sure you water them enough, especially during dry spells or hot weather.
However, be careful not to overwater them either, as this can also cause the leaves to turn brown. Striking a balance with watering is key. Remember that excessive heat can also lead to browning, so providing some shade or dappled sun for your plants is important.
Adjust fertilization practices
To fix brown hydrangea leaves, it’s important to adjust your fertilization practices. Insufficient fertilizer can cause nutrient deficiencies, especially a lack of potassium, leading to brown leaves.
On the other hand, using the wrong formula or fertilizing at the wrong time can burn the roots and foliage, resulting in brown leaves as well. Excess nutrients in the soil can also dry out and damage the roots of your hydrangeas, causing their leaves to turn brown.
By adjusting your fertilization practices and making sure that you provide the right nutrients in appropriate amounts, you can help prevent brown leaves on your hydrangeas.
Treat insect infestations
If you notice brown spots or holes on your hydrangea leaves, it could be a sign of insect infestations. Insects like aphids, spider mites, and scale can damage the leaves and cause them to turn brown.
To treat the infestation, you can try using insecticidal soap or neem oil spray. These products are safe for plants and will help eliminate the pests. Remember to follow the instructions on the packaging when applying these treatments.
Regularly inspect your hydrangea plants for signs of insects and take prompt action to prevent further damage.
Address fungal diseases
Fungal diseases like Cercospora leaf spot and anthracnose can affect hydrangeas, causing brown spots on the leaves and cankers on the stems. These diseases can also make the leaves turn yellow or purple.
To address fungal diseases, it is important to remove any brown leaves from the plant to prevent further spread. Using a fungicide can also be effective in treating hydrangea leaf spot.
Taking these measures will help keep your hydrangea healthy and free from fungal infections.
Provide shade or protection from excessive sun exposure
To prevent your hydrangea leaves from turning brown, it’s important to provide shade or protection from excessive sun exposure. Too much sunlight can cause the leaves and flowers to brown and eventually fall off.
Find a spot in your garden where your hydrangeas can get some shade during the hottest parts of the day. You can also use a shade cloth or place potted hydrangeas under a tree or patio cover to shield them from direct sunlight.
By giving your plants some relief from the intense sun, you can help keep their leaves healthy and vibrant.
Protect the plants from strong winds
Strong winds can be a cause of brown leaves on hydrangea plants. They can damage the delicate foliage and flowers, leading to unsightly brown spots. To protect your hydrangeas from strong winds, you can create a barrier using stakes and mesh or wrap the plants in burlap.
This will help shield them from the direct force of the wind and prevent the leaves from drying out or getting damaged. It’s important to secure the protective covering well so that it doesn’t blow away in strong gusts.
Taking these steps to protect your hydrangea plants from strong winds can help maintain their health and prevent those brown leaves from appearing.
Preventive Measures to Keep Hydrangea Leaves Healthy
Choose a planting location that provides adequate sunlight and has good drainage.
Choose the right planting location
To keep your hydrangea leaves healthy and prevent them from turning brown, it’s important to choose the right planting location. Make sure you pick a spot that provides the appropriate amount of sunlight for your hydrangeas.
Too much sun can cause damage and result in brown leaves, so consider moving your plants to a shadier area if necessary. By selecting an ideal location, you can help maintain the health and beauty of your hydrangeas.
Ensure proper drainage
Proper drainage is really important for your hydrangeas to stay healthy. If the soil doesn’t drain well, it can cause the leaves to turn brown. When there’s not enough drainage, the water gets stuck in the soil and makes it hard for the roots to breathe.
As a result, your hydrangea might get sick and its leaves may shrivel and turn brown. To prevent this from happening, make sure you plant your hydrangea in well-draining soil or use containers with drainage holes.
This will help excess water flow away from the roots and keep your hydrangea leaves nice and green.
Implement proper watering techniques
To keep your hydrangea leaves healthy and prevent them from turning brown, it’s important to implement proper watering techniques. Hydrangeas need regular and deep watering to stay hydrated and thrive.
One key tip is to avoid watering from overhead, as this can lead to brown spots on the leaves. Instead, water directly at the base of the plant or use a soaker hose to ensure that the water reaches the roots without wetting the foliage.
Consistency is also crucial – make sure you water your hydrangeas consistently and deeply, especially during hot and dry periods, to provide them with adequate hydration. By following these watering practices, you can help keep your hydrangea leaves vibrant and green.
Monitor and address pest and disease issues promptly
To keep your hydrangea leaves healthy, it’s crucial to monitor and act quickly when it comes to pests and diseases. Pests like aphids, mites, and caterpillars can cause damage by feeding on the leaves.
Additionally, fungal diseases such as leaf spot and powdery mildew can lead to brown spots or discoloration. To address these issues promptly, regularly inspect your plants for any signs of infestation or disease.
If you notice any pests or unusual spots on the leaves, take action immediately by using appropriate pesticides or fungicides recommended for hydrangeas. By staying vigilant and addressing pest and disease problems promptly, you can help ensure that your hydrangea leaves stay healthy and vibrant.
Provide appropriate shade and protection
To keep your hydrangea leaves healthy and prevent them from turning brown, it’s important to provide appropriate shade and protection. This means finding the right spot for your plants where they get some sunlight but are not exposed to excessive sun.
Too much sun can lead to sunburn on the leaves, causing them to turn brown. It’s also important to protect your plants from extreme temperatures, especially during cold snaps in spring that can damage emerging leaves and flower buds.
By replicating their natural habitat and providing shade and protection, you can help keep your hydrangeas healthy and prevent those unsightly brown leaves.
