Most of my citrus is twenty years old now, I got ambitious when my wife and I took a road trip to Disney Florida in my (then) new dodge truck and bought back a lot of trees. I have a naval orange, Orlando Tangelo, Honey tangerine, Meyers Lemons, Ponderosa lemon, Hamlin Orange. My Avocados are four years old and younger, I have Stewart, Brogdon, Bacon, Wertz, and the rest are grafted by myself from scions begged, pleaded, and bought. I have Bonny Doon, Green-gold,and several Mexican unknown grafts from forum friends who swear they are good. I also received some Bonny Doon avocados from a different forum friend that were over ripe so didn't really taste good but I started all of those seeds just to see what will happen.
P.S. I also have Hibiscus to protect from the cold.
P.P.S twenty years ago they still allowed citrus to go across state lines.
