Why do lemon blossoms fall off?

The lemon flowering season varies depending on the variety of the same and, especially, the climate. In a typical temperate climate, the average lemon tree will flower about twice a season, usually between spring and summer and at the end of it. In the northern hemisphere, this will be approximately between March and July for the first bloom and between August and September for the second.

However, this is far from being a firm rule. The flowering of the lemon tree is re-blooming, and in warm and mild enough climates, such as in the tropical and subtropical ones, a lemon tree can flower up to 4 times a year, which will mean that it will spend practically the entire season bearing fruit.
