Leaf curls on lime trees are not necessarily a sign that your tree is dying. Causes for the distress could be diseases, parasites, or improper care. Not to worry, though: if you take quick action, you can reduce the the damage before it gets any worse. First do a deep watering at least twice a week, but be careful and don’t leave a puddle at the base of the tree. Other things you can do is use Neem oil and basic fungicides. These tips can get your tree back in good shape.
- It’s vital that you first thoroughly examine your lime leaves before attempting to treat them
- Be sure you are not giving too much water to the plant, but also be sure you aren’t depriving it of enough water
- If you have determined that it is bugs/parasites that are causing the damage, you can use neem oil to help prevent any further damage
