Our white grapefruit tree does not have any fruit this year. Last year it had quite a few. Any ideas why no fruit this year? We also have a lemon tree that is at least 3 years old and has never had any fruit. We were thinking about taking it out.

Your Lemon tree is still quite immature and really only began to enter the fruiting years at about 5 years.
