Here are the 14 reasons why are lemon tree leaves curling and turning yellow?

The illness and pests including mite infestation, mealy bugs, and aphids are causing the lemon tree’s leaves to curl. African violets are most frequently affected by this problem, though it can occur in many different kinds of trees. The illness makes the plant’s leaves coil up, become yellow, then brown, giving the impression that the plant is perishing. If you notice that your plant has this disease, be sure to use an insecticide to eliminate all infected leaves and to trim off any affected leaves.

Too much Heat Stress

Too much heat stress can cause lemon tree leaves to curl, which is a regular issue. The lemon tree’s leaves curl because it is in direct sunshine. The plant feels dry since the sun has drawn out all the water from the soil, so it curls up to prevent the leaves from scorching. Plants can conserve water from leaves in this fashion, but they are unable to prevent a leaf from burning. That’s why it will eventually perish if the site isn’t altered. You can try moving it or even placing it in a position with some partial shade to prevent this. Try sprinkling the leaves with a spray bottle or spraying them with water if you still see the leaves curling.

Low Light

The leaves of the lemon tree will begin to curl upward, turn yellow, and ultimately turn brown if it does not receive enough sunlight. If you reside in a low-light environment, you can either move the plant to a brighter position or use artificial growth lights to provide it with extra light. To allow room for fresh leaves to grow, pluck and discard any leaves that become brown. To create food, plants always want to receive a few hours of sunlight or at least some partial light; if they don’t, they will begin to wilt, which is an indication of insufficient light.

Low Watering

Because the plant is not receiving enough water, the leaves of the lemon tree are curled. Watering your plants on a regular basis is crucial, not simply when you recall when out for a walk and checking other things. Your plant will begin to droop and curl its leaves if it is not receiving enough water. It will begin to droop and die, which is a sign that it needs more water. Make sure to water your plant every day, not just when you remember to, to help maintain it healthy.

Lack of Nutrition

Another major problem that can affect any plant is a lack of nourishment, which is why the lemon tree’s leaves curled up. The leaves begin to twist and wilt, and they gradually lose their life. The impact of this problem can be seen in the leaves themselves as a result of the insufficient nourishment in the potting soil. Try adding more fertilizer or watering your plant more frequently if you see the leaves curling on your plant.


One of the biggest mistakes people make is feeding lemon plants too much food. This is because we are really excellent at believing that providing our plants with more nutrients will cause them to grow more. When you overfeed plants, they actually curl up and eventually die rather than growing more. The easiest method to avoid this is to gradually reduce the amount of food you give your plants until they are simply receiving enough water and light.

Root Rot

Due to root damage, the lemon tree’s leaves were curling. Because of the rotting roots, the plant was unable to absorb the water from the soil. The soil’s water and nutrients could not be absorbed by the lemon tree. To remedy this, first remove the plant from its current pot and trim the rotten roots. The leaves had started to wilt and turn brown. Move your plant to a fresh container with fresh soil after that. Now, give your plant some TLC; this will help with the root rot issue.

Water Quality

Because of the water’s poor quality, plants’ leaves are not growing well and appear to curl inward or outward. Although still green, the leaves were fading and turning brown. The plant was rapidly approaching death since it was growing feeble and malformed. The plant may wilt as a result of contaminated water from the tap, bucket, or other source. Change your plant’s water to remedy the problem, and it will quickly begin to recover. You should also remove the plant’s curled and damaged leaves.

Temperature Stress

Due to temperature stress, lemon tree leaves are curling, which prevents your plant from growing properly. You might try lowering the temperature to between 75 and 80 degrees Fahrenheit to see if that solves the issue. Whether not, change it to 55–70 degrees F and check to see if the plants begin to thrive.

Too much Direct Sunlight

Too much direct sunshine was causing the lemon tree’s leaves to curl. The leaves were drooping, dying off, and turning brown. The solution is to relocate the plant to a suitable location with some shade and light. If the plant exhibits evidence of curled leaves, relocate it right away because it will be content after that.

Transplanting Stress

Stress from the transplant causes the lemon tree’s leaves to begin to curl. The roots of plants frequently suffer damage during transplantation, which shocks the plant and leads it to display symptoms like curled leaves. Carefully removing the plant without damaging its roots is one approach to avoid this. Additionally, use fresh soil to prevent the spread of the potting soil illness.

Low Humidity

Due to the low humidity, the lemon tree’s leaves are curling. Many hardy plants commonly struggle with low humidity. It might be challenging for plants to prevent their leaves from curling up when the humidity in your home drops below a particular level. The reason for this is that the plant’s leaves depend on water vapor to keep strong and alive. You should give your plants more water to prevent curling if the relative humidity in your home is too low. In order to prevent leaves from wilting, you should also spray water on the soil or just provide water to it.

Insect Infestation

Lemon trees’ leaves may curl if there is an insect infestation. The main leaves of the plant have curled around the edges, giving it a spiky appearance. It becomes withered and discolored due to the insect. The health of the plant as a whole is being harmed by the insects consuming the leaves. This indicates that a pesticide or insecticide is necessary to get rid of all the pests present on the plant.

Not just lemon trees can experience overwatering-induced leaf curling. All plants can experience this problem. Overwatered plants that are frequently moist will begin to wilt and droop. The best course of action is to ensure that your plant receives just enough water—not too much. You must first wait for the plant to thoroughly dry the soil before beginning to give it less water to solve this issue. Additionally, remove all of the curled leaves.

There are a few treatments you may do if the leaves on your lemon tree are curling to help them get back to their normal shape.

  • Make sure the plant is well-watered and receiving enough sunlight first.
  • Second, check to see if there are any pest infestations that could be causing the leaves to curl.
  • Third, ensure sure the plant is not in an environment that is too hot or too cold because this could negatively affect its health and result in symptoms like curling, yellowing, or browning of the leaves.
  • Last but not least, give the plant a decent slow release or general fertilizer a few times within 2 months of the growing season to ensure that it has enough water and nutrients.

    How do you stop leaf curl?

    Use insecticide to combat the pests that caused the lemon tree’s leaves to curl. Even while the curled leaves won’t become green again, killing all the insects will address the general leaf curling issue. The younger leaves will be healthier and greener.

    Why do citrus trees get curly leaves?

    The aphid bug is the most frequent cause of the twisted leaves that turn yellow or brown on citrus trees. As a result of the nutrients being removed from the leaf, which causes it to curl and drop, they suck plant sap, weakening the plant. Use a pesticide on lemon trees to get rid of aphids and so avoid their occurrence.

    How To Prevent Leaves Folding of lemon trees?

    Place it in some shade to avoid the leaves from folding, and give the soil a good soaking to keep it hydrated. If not, wait a little longer; if they don’t develop green in 1-2 days, they might come back to life because of too much sunlight or watering. Remove the leaves in this situation and allow the new leaves to grow. Don’t overwater your plant to avoid overwatering.

    How to care for lemon trees?

    Lemon tree maintenance involves timely nutrition provision, good sunlight exposure, and appropriate watering. Don’t worry if there is a pest infestation; all you need to do is use an insecticide or pesticide to kill or at least repel the pests.

  • Water your plant until the top 2 inches of soil are completely submerged.
  • Lemon trees in a somewhat shaded region that receives some sunlight.
  • Use a general-purpose fertilizer to add nutrients to the soil around your plants so they can thrive.
  • We avoid any root rot concerns by using a well-draining pot that drains the water.
  • Another crucial aspect of care for lemon trees is to check on them everyday to monitor their health.
