There are hundreds of breeds of citrus leaves, but you would be amazed at what types of citrus leaf identification there are. Here a few to learn about. Did you know that grapefruit and orange trees can grow up to thirty feet tall? That lime or lemon trees grow like a shrub and reach no more than thirteen feet tall? Or a mandarin tree will only grow up to twenty-five feet tall? These factors are important on identifying citrus leaves.

An orange leaf is dark green, long, and pointed but round at the base. They can grow up to five inches long and actually live up to a full three years! The flowers they bloom are white. Grapefruits are exactly like the oranges. They can grow between three to five inches long, pointed at the tip, with a round base. Their leaves are considered evergreen and can live as long as two years. They also produce white flowers. The mandarin and tangerine leaf are very similar to a grapefruit or an orange tree but the leaf can be either slender or broad.

The leaf of the lemon tree has teeth on the edges which is called elliptical. Their colors are dark green on top and underneath are light green. Their flowers are white with purple underbellies. Lime trees fall in the same class as lemons do. The leaf can grow between two to three inches long. They also have teeth on their edges. The flowers are white but tinged with purple. Kumquat trees have dark green leaves that ranges from 1 1/4 to 3 1/2 inches in length. The tree itself can grow up to fifteen feet tall. They produce white flowers along with the fruit.

All these types of Citrus can produce diseases. Just by looking at the leaves you can tell what type of disease the plant is having. Here are a few examples. Citrus Canker is a very contagious bacterial infection that gives lesions or scabs in yellow coloring on the fruit and trees. Melanose loves to attack Grapefruit trees. It is a fungus that kills the young fruit. Greasy Spot is easily recognizable from the brownish-yellow ugly blisters that show on the leaves of the trees. Sooty Mold blackens the leaves which turn into mold from secretions of insects. With all these different types of citrus leaf identification and diseases, you can learn something new about your citrus plant that you may not have ever known before!
