Dwarf Hybrid Avocado Tree ('Holiday')
Mail-ordered. Fruits in the fall/early winter (hence, 'Holiday'), according to the tag attached when received, lo these many years ago now!
This dwarf is now in the ground 4-5 years. Last two years, it has flowered like crazy in the Spring. Then the flowers all fall off. Very healthy, dark green glossy leaves. About 9-10 feet tall now. All of a sudden this summer, while we were away, what I will call a 'sucker' jumps out of the ground at the base, near the trunk, and has grown, in one season, mind you, 12-13 feet. Taller than anything else, and very straight. The rest of the tree is 'bushy' with limbs and leaves from ground level to the crown in a round sort of form.
Question: what is that thing? Could it be a 'revert' from the root stock? Bark is very light green and soft from ground to tip.
Please help. Gotta get some fruit offa this tree before I die!!! Drew
