First, lemons don't need bees, or any help from you to make lemons; the lemon flower is a perfect flower, meaning it has all the parts necessary to make fruit. The petals fall off, whether or not they get pollinated; BB size fruit then appear. If the tree is quite young, often most or all the flowers will fall without making any fruit; it is because the flowers produced by young trees are often not mature. In the case of Meyers the earliest flowers often lack the signature purple base and are solid white; rarely will those produce fruit. Take care of your tree, have a little patience; and it will make fruit soon enough.

Thanks again You were a hug help. :-)

Always happy to help. I am a frequent visitor to this site; because I learn so much more than I am able to contribute.

FYI Guatemala will very soon be the largest producer of Meyer lemons in the world; we have 16,000 trees now with a 5 year plan of 50,000 trees producing 15 million fruits per year.
