Gainesville Observations: Flowers appear in late March after many trees have already flowered. The small leaves also appear late March filling the stiff branches. Trees are performing very well and should do well south of our test plots. Trees are challenging to prune into a tight canopy that would be presentable to those that purchase trees for landscapes. Thorns might be an annoyance when used close to people. A dominant trunk can be developed with staking and pruning. Branches and leader need to be headed in order to produce a tighter canopy that would be appealing to buyers.
