My 4-year old haas is in a sunny spot on our deck in Northern California. USDA zone is 10a and the container is 25 gallons.
It has continued to grow as expected, but zero signs of flowering. This tree was purchased from a nursery as a very young, but pre-grafted tree that should provide fruit when mature. It is about 6' tall in the container now.
I don't have any place to plant it, so it remains in the container.
Besides regular water and sun, what cultural elements are required to turn this into a fruiting avocado tree? Will it ever fruit in a 25 gallon container?
