I Have Two Carob Trees Over 14 Years Old. They Have The Spirally Flowers But Do Not Fruit.

Question

How do I know whether I have two male or two female trees. What can I do about this. Is it too late to graft at their age?

Answer 1

The chances that you have trees that have, both, male and female flowers is extraordinarily high. In most cases, each tree will have both sexes present. In very rare cases, a tree will be one or the other, but the chance that both are the same sex, and only one sex, will be near impossible.

That means that the only thing stopping fruit production will be climate. These trees like it dry. Very dry. Likely, they will only produce when the climate is just right, unfortunately.

Here is an article that will help you to know what they require:
