Q.I Have 2 Olive Trees And Neither Produce Fruit. What Can I Do To Have Them Produce?
One of the trees is about 8-9 feet tall, was purchased locally (South Georgia) which I took to Maryland and planted it there. It had several olives on it when I bought it which either dropped off or perhaps the squirrels or birds ate them. We moved to South GA (Jesup -31545)in 2017 and I brought the tree with and replanted it here. I also bought a second tree locally and planted it next to the original one. Neither has ever produced more fruit. The latest tree is about 5-6 feet tall and grows about feet from the first, larger, tree. What can I do to make them produce?

The first thing will be to test the soil for deficiencies and pH swings. These articles will help:

The next thing to consider will be how long the trees have been planted. Generally, you can expect at least 2 years before the tree establishes, fully. After then, if they still haven't produced, then you can move on to diseases. Generally, there will be signs of disease that are very noticeable.Browning leaves, black spots, or other symptoms will indicate disease.
One last thing to consider will be that you make sure that the tree is not an ornamental olive. These will never bear fruit to an amount that will be enough to eat.
