Did You Know?
1. The curling of leaves on a lemon tree can be a sign of a magnesium deficiency in the soil. Adding Epsom salt around the base of the tree can help replenish the magnesium levels and alleviate the curling.
2. Citrus leaf curl, a common condition found in lemon trees, is caused by the citrus leafminer. These tiny moths lay eggs on the leaves, and when the larvae hatch, they burrow into the leaves, resulting in curling.
3. Have you ever wondered why only some leaves on your lemon tree are curling? Well, it turns out that certain tree branches can be more prone to leaf curling due to variations in sun exposure, temperature, or even genetics.
4. Interestingly, lemon trees may exhibit leaf curling as a defense mechanism against excessive sun exposure. By curling their leaves, lemon trees reduce the amount of direct sunlight hitting the leaf surface, thus minimizing water loss through evaporation.
5. In some cases, leaf curling can also be attributed to a fungal or viral infection in lemon trees. One example is the citrus tristeza virus, which can cause the leaves to curl, yellow, and eventually drop. Proper care and prompt treatment can help mitigate the damage caused by such infections.
Temperature
Lemon trees are sensitive to extreme temperatures, both hot and cold. When exposed to hot temperatures, the leaves may curl as a protective mechanism to minimize water loss. Similarly, in cold temperatures, the leaves curl to reduce surface area and conserve heat.
To mitigate the effects of temperature on leaf curling, it is important to adjust watering practices accordingly. In hot conditions, regular application of Tui Organic Seaweed Plant Tonic can help provide necessary nutrients and improve a plant’s ability to withstand heat stress. Conversely, in cold conditions, over-watering should be avoided, as excess moisture can lead to root rot and leaf curling.
It is essential for lemon tree owners to monitor the weather and make appropriate adjustments to watering schedules to support healthy leaf growth and prevent curling.

Insect Infestations
Insect infestations can be a common cause of leaf curling in lemon trees. Pests such as scale, mealy bugs, mites, and aphids feed on the leaves, causing damage and distortion. When infestations occur, the tree’s natural response is to curl the leaves in an attempt to protect itself.
To combat insect infestations, it is crucial to identify the specific pest plaguing the lemon tree. Ants crawling up the tree can be an indication of scale insects, mealy bugs, or aphids. In such cases, it may be necessary to seek advice from a local garden center for an appropriate insecticide spray. Timely intervention can prevent further damage and alleviate leaf curling.

Over-Watering
Over-watering is a common mistake made by lemon tree owners and can lead to leaf curling. When the roots are constantly exposed to excess moisture, they become waterlogged, leading to poor oxygen circulation and root rot. As a consequence, the tree’s ability to absorb nutrients is hampered, resulting in leaf curling as a visible sign of stress.
To avoid over-watering, it is important to ensure that the soil has adequate drainage. Water the lemon tree only when the top layer of soil feels dry to the touch. This practice will prevent waterlogged conditions and help maintain optimal root health.
Leaf Curl Disease
Leaf curl disease is a common issue affecting lemon trees, caused by a viral or fungal infection. It results in the distortion, curling, and yellowing of the leaves. The disease can be transmitted through contaminated pruning tools, insects, or infected soil.
To control leaf curl disease, it is recommended to use a copper-based clean-up spray. This spray should be applied during autumn and winter at 10-14 day intervals until spring bud burst. The treatment helps mitigate the effects of the disease and promotes healthy leaf growth.
It is important to collect and burn or properly dispose of infected leaves, as composting can spread the infection. Proper sanitation practices can effectively prevent the disease from spreading to other lemon trees.
Lemon Tree Varieties Susceptibility
Certain lemon tree varieties are more susceptible to leaf curl disease than others. It is important for lemon tree owners to research and select varieties that are relatively resistant to leaf curling. By choosing a resistant variety, the risk of leaf curl disease can be reduced.
However, even resistant varieties can still experience leaf curling due to other factors such as temperature, insect infestations, and over-watering. Careful attention to all potential causes is necessary to ensure the health and vigor of lemon trees.
Adjust Watering
To combat the effects of extreme temperatures, adjusting watering practices is crucial. Lemon trees should be watered more frequently during hot conditions to prevent dehydration and leaf curling. Conversely, in cold conditions, it is important to be cautious about over-watering as excess moisture can lead to root rot and leaf curling. Monitoring the weather and adapting watering schedules accordingly can help maintain healthy leaf growth.
Apply Seaweed Plant Tonic
During hot conditions, applying Tui Organic Seaweed Plant Tonic regularly can provide much-needed nutrients and enhance the tree’s resilience against heat stress. This organic tonic helps improve the overall health of the lemon tree and supports proper leaf development, reducing the risk of curling.
