Fungal infection can cause brown spots on the leaves, which can spread quickly and cause the leaves to turn brown. Pest infestation, such as spider mites and scale insects, can also cause brown leaves.
If you notice brown leaves on your cherry laurel, it is essential to identify the cause and take appropriate action. You can prune the affected leaves, use organic fungicides, or insecticides to control pests and avoid using chemical fertilizers.
Cherry Laurel Leaves Turning Yellow and Brown – 4 Common Problems
Cherry laurel leaves turning yellow and brown can be due to a variety of reasons. In this section, we will discuss the most common causes of this issue and how to address them.
1. Improper Care
One of the most common reasons for yellow or brown leaves on cherry laurel is improper care. Overwatering, lack of water, and waterlogging can cause leaves to turn yellow and eventually brown. Similarly, drought stress and lack of water can also lead to leaf discoloration. It is important to water cherry laurel plants deeply and regularly, but not excessively.
2. Nutrient Deficiencies
Cherry laurel plants require a balanced supply of nutrients to thrive. A deficiency in nitrogen or iron can cause yellowing of leaves, while a deficiency in lime can lead to chlorosis, which is the yellowing of leaves between the veins. It is important to fertilize cherry laurel plants regularly with a balanced fertilizer to ensure they receive all the necessary nutrients.
3. Sunburn and Frost Damage
Cherry laurel plants are susceptible to sunburn and frost damage, which can cause leaves to turn yellow and brown. Sunburn occurs when the plant is exposed to direct sunlight for extended periods, while frost damage occurs when the plant is exposed to freezing temperatures It is important to protect cherry laurel plants from extreme weather conditions and provide them with adequate shade when necessary.
4. Disease and Pests
Diseases and pests can also cause yellow and brown leaves on cherry laurel plants. For example, white prunicola scale can cause leaf yellowing and dieback. Look for white scale covers on the trunks and branches.
This is an armored scale that sucks out cell contents. It is often found on weakened plants. It is important to regularly inspect cherry laurel plants for signs of disease or pests and address them promptly.
Role of Planting and Location
The planting and location of cherry laurel can play a significant role in the health of its leaves. Cherry laurel prefers a well-drained soil and adequate space for its growth.
The shrub can tolerate a wide range of soil pH values, but it prefers a slightly acidic to neutral soil pH between 6.0 and 7.5. Soil compaction can lead to poor soil drainage, which can cause waterlogging and root rot, leading to yellow and brown leaves.
Cherry laurel prefers full sun to partial shade, but it can tolerate some shade. If the shrub is planted in a shady location, it may not receive enough sunlight, which can cause yellow leaves. On the other hand, if the shrub is planted in a location that receives too much direct sunlight, it can cause leaf scorching, leading to brown leaves.
If the cherry laurel is moved or undergoes a change of location, it may experience transplant shock, which can cause yellowing of leaves. To minimize transplant shock, it is recommended to transplant the shrub during the dormant season and provide adequate water and nutrients.
Indoor cherry laurels can also experience yellowing of leaves if they do not receive adequate light or if the air is too dry. To prevent yellowing, it is recommended to place the plant near a bright window and to mist the leaves regularly.
Impact of Seasonal Changes
Cherry laurel leaves can turn yellow and brown due to a variety of reasons, including seasonal changes. While cherry laurels are hardy and can tolerate a wide range of conditions, they are not immune to the effects of the changing seasons.
During winter, cherry laurels can experience winter damage, which can cause leaves to turn yellow and brown. This is especially true if the winter is particularly harsh or if the cherry laurel is located in an area that is exposed to cold winds.
To prevent winter damage, it is recommended to protect the cherry laurel with a windbreak or to relocate it to a more sheltered area.
In late summer, cherry laurels can experience dry stress, which can also cause leaves to turn yellow. This is because cherry laurels have shallow roots and are sensitive to drought. To prevent dry stress, it is recommended to water the cherry laurel regularly, especially during dry periods.
In February, cherry laurels can experience frostbite, which can cause leaves to turn brown. This is because frost can damage the cells in the leaves, causing them to die and turn brown. To prevent frostbite, it is recommended to cover the cherry laurel with a frost blanket or to relocate it to a more sheltered area.
Watering and Fertilization Practices
Yellowing and browning of cherry laurel leaves can be caused by incorrect watering and fertilization practices. Cherry laurel plants require moderate watering and well-draining soil. Overwatering can lead to root rot, which can cause leaves to turn yellow and brown. On the other hand, underwatering can cause leaves to dry out and turn brown.
To ensure proper watering, it is recommended to check the moisture level of the soil regularly. The soil should be moist but not waterlogged. If the soil feels dry to the touch, it is time to water the plant. It is also important to avoid watering the leaves, as this can cause fungal diseases.
Fertilization is another important aspect of cherry laurel care. Annual fertilization is recommended to provide the plant with the necessary nutrients. Lack of nutrients can cause leaves to turn yellow and brown. A quick-release fertilizer can be used to provide the plant with quickly available nutrients. It is important to follow the manufacturer’s instructions when applying fertilizer.
It is also recommended to use an acidic needle compost when fertilizing cherry laurel plants. This type of compost provides the plant with the necessary nutrients and helps to maintain the soil’s pH level. It is important to avoid over-fertilization, as this can lead to root burn and damage the plant.
Disease and Pest Management
Cherry laurel leaves turning yellow and brown can be caused by various diseases and pests. It is important to identify the specific problem in order to treat it effectively. Here are some common issues and their management:
Fungal Infections
Fungal infections such as powdery mildew and shot hole disease can cause cherry laurel leaves to turn yellow and brown. Powdery mildew appears as a white, powdery substance on the leaves, while shot hole disease causes small, circular holes in the leaves.
These infections can be managed by removing infected leaves and branches, improving air circulation, and applying fungicides.
Pests
Pests such as spider mites and scales can also cause cherry laurel leaves to turn yellow and brown. Spider mites are tiny, spider-like insects that feed on the leaves, while scales are small, oval-shaped insects that attach to the leaves and suck the sap. These pests can be managed by applying insecticidal soap or horticultural oil.
Pseudomonas syringae pv. syringae
This bacterial disease causes dark brown spots on the leaves, which eventually turn yellow and fall off. It can be managed by removing infected leaves and branches, improving air circulation, and applying copper-based fungicides.
Care and Maintenance of Cherry Laurels
Cherry laurels are relatively low-maintenance shrubs that can thrive in various conditions. However, proper care is crucial to prevent yellow or brown leaves and ensure healthy growth.
1. Watering
Cherry laurels require regular watering, especially during the first year after planting. They prefer moist soil but can’t tolerate waterlogging. Therefore, ensure that the soil is well-draining and doesn’t hold water for too long. During hot and dry weather, water the shrubs deeply once or twice a week.
2. Pruning
Pruning cherry laurels is essential to maintain their shape, size, and health. It’s best to prune in late winter or early spring before new growth appears. Remove any damaged, diseased, or dead branches, and thin out crowded or crossing branches. Avoid pruning more than one-third of the shrub’s total volume at once, as it can weaken the plant.
3. Mulching
Mulching can help retain moisture, suppress weeds, and regulate soil temperature around the cherry laurels. Apply a layer of organic mulch, such as bark, wood chips, or leaves, around the base of the shrub, but avoid piling it against the stem. Mulch once or twice a year, in spring and fall, but don’t overdo it, as too much mulch can cause root rot.
4. Transplanting
Transplanting cherry laurels can be stressful for the plants and should be done carefully. The best time to transplant is in fall or early spring when the shrubs are dormant.
Choose a new location with similar soil and light conditions, and prepare the planting hole twice as wide as the root ball. Water the plant thoroughly before and after transplanting, and avoid fertilizing for the first year.
5. Prevention
Preventing yellow or brown leaves on cherry laurels is easier than treating them. Here are some preventive measures:
- Choose healthy and disease-resistant cultivars.
- Plant cherry laurels in well-draining soil and avoid waterlogging.
- Don’t overwater or underwater the shrubs.
- Avoid excessive pruning or pruning at the wrong time.
- Monitor the plants regularly for pests and diseases and take prompt action if necessary.
Overall, cherry laurels are easy-to-grow shrubs that can add beauty and privacy to any garden. With proper care and maintenance, they can thrive for many years and provide a lush green backdrop to your landscape.
Remedial Measures for Discolored Leaves
When cherry laurel leaves turn yellow or brown, it is important to take remedial measures to prevent further damage to the plant. Here are some countermeasures that can be taken:
