Citrus trees love warm weather and usually do quite well in warmer states. However, the warmer the weather, the more issues will be had with citrus leaf problems. You will find that in warmer climates, you will have leaves falling off a citrus tree for various reasons. Orange, lemon and lime tree leaves are all prone to the same types of problems.
Citrus Leaf Problems
The most common citrus leaf problems for lemon, lime and orange tree leaves is leaf drop. This can be caused by any number of reasons, but the most common is a great fluctuation in temperature, causing the leaves falling off a citrus tree to continue to drop until the tree can handle the temperature once more.
Citrus trees like warm weather but do best in temperatures that don’t go much above 60 to 65 degrees F. (15-18 C.) Further, whether you have your citrus trees indoors or out, you should make sure the temperature doesn’t fluctuate and is more of a constant temperature. This will definitely help stop leaves falling off a citrus tree.
Citrus leaf problems can also be caused by scale. Scale insects will cause orange, lime and lemon tree leaves to fall off the trees as well. These insects can be removed from the leaves of the citrus tree with a sharp knife. You can also use your fingernail or a Q-tip soaked in alcohol. If you find that there are too many insects to remove this way, you can spray the tree down. Either spray the tree leaves with alcohol, or if you want to go a more natural route, use a mixture of lemon juice, garlic juice and cayenne pepper. Neem oil spray is effective too.
If, after checking the tree out thoroughly, you find the leaves falling off a citrus tree in your home or yard, you should make sure the soil around the roots is wet enough. These trees like a lot of water and you need to be sure you water them thoroughly each time you water them. Instead of just looking for signs of soil dryness, you might want to poke your finger into the soil so you can feel how damp the soil is beneath the surface.
Orange tree leaves and other citrus tree leaves are very prone to leaf drop and doing whatever you can to prevent your citrus tree leaves from dropping should definitely help your cause. If you do your best to prevent the major causes, you shouldn’t have too many problems with these hardy trees.
