Hass avocado tree size
I bought a Hass avocado tree from the Home Depot the other day. The tag says its mature size is 8-12' tall x 8-12' wide and I thought that is reasonable to plant in my backyard. However, when I did some research on it, I learned that Hass tree can grow very big, up to 40', which is definitely not an option for my backyard.
Is there a variety of Hass that is actually small? Or does the tag have wrong information?
Or will frequent prunning be needed to keep it a manageable size?
I need to decide whether or not to return it, so would appreciate any inputs.
