Attention pitangatuba growers!
Pitangatuba has a huge taproot system! I repotted a 7 gallon plant into a 15 gallon pot. The roots went through the bottom of the 7 gallon pot more or less half of a yard, approximately 45 centimeters. Today, I looked at the plant and it did not miss a beat....flowers opening and fruits forming as if nothing ever happened! I have been harvesting fruits from pitangatubas since april, non-stop, and it looks like it will continue for as long as the weather is hot.
I would recommend sowing seeds in a deep pot and growing the tree/plant in the tallest pot available. Pitangatuba are like gold fish, the bigger and deeper the pot, the bigger they will get.
