My citrus tree isn’t producing any citrus! What am I doing wrong?

If there are no natural pollinators like humming birds or bees they wont flower, which means no fruit. Watering could also be an issue. Citrus trees do best if they are heavily watered, and then given time to dry out between waterings. The amount of times the tree should be watered all depends on the soil it is in. But, trees typically need to be watered every one to two weeks in the summer, and every three to four weeks in the winter.
