Hey Walkie,

The pot is too small.. And on top of that it seems to only be half way full.. You could try to transplant but that would be difficult now and larger transplants don't take too well.. If it were me I'd prune up the first 3-4 nodes (branches) and fill the pot to the brim with soil.. In the future - 10 gals and up .. Good luck =)

Also, a black pot in zone 10 may be cooking the roots..try wrapping the pot with aluminum foil to reflect some of the heat. ( don't cover drainage holes) Next year take michaels suggestions about pot size.
