Citrus Leaf

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.

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.
