Lemon trees grow in warm climates and will not survive if they are exposed to cold weather for any length of time. Under ideal conditions these trees grow continually, producing fruit all year long.
There are different types of lemon trees that produce fruit to suit different tastes and climates. This includes hybrids such as the Meyer, a lemon-mandarin cross.
Dwarf lemon trees grow less than 10 feet tall and are often kept as potted plants. The average height of a standard lemon tree is about 10 to 20 feet. Sometimes they are pruned to keep the tops reachable.
Fruit production begins as soon as the flowers drop, and a tiny lemon can be seen within a short time. Because lemons will keep growing until they are picked, there is no set time from bloom to fruit. Lemons are usually picked around five months after the first blooms appear.
