So, I normally manage to get mango trees that came from Zill's. But figured I had worn out my welcome there maybe, so decided to try Excalibur at http://excaliburfruittrees.com/index.html

So went by and asked for a Nam Doc Mai #4. Young fellow and I went to get it, picked it out, brought it back to checkout lady. She says "not a #4'. So he went back to get the right one. Didn't pay much attention to pot size; had asked for a 3 gallon. Went to plant it a few days later and realized - whoaa, this is not nearly as big as Zill's 3 gal pots - also the root ball pretty much fell apart so apparently only recently transplanted to that pot. They of course charged me the $$ for a 3 gallon mango. I didn't bother going back and will never go back. Hopefully the tree will grow.

Below is a pic of the Zill and the Excalibur 3 gallon pots. The pavers underneath are 12 inches square.
