There are over 20 varietals of avocado and each of the varieties inhabit O`ahu island. Currently, we have the winter sharwil varietal. We do not graft our trees as our use for them is in agroforestry, but you are welcome to do with them whatever you wish. Our saplings are all over 1 ft and are ready to be outplanted once you find the time. It takes 5-10 years, depending on soil and care, for avocados to bear fruit.
