Today I cleaned up a 11-ft X 11-ft, in ground Cara Cara navel. First, I cut out all the small dead twigs. Second, removed all branches that were occupying the same aerial space as another branch. Third, opened up the middle of the tree to let more sunlight reach the interior. Fourth, I sprayed the entire tree with Ultra Pure horticultural oil and a little Tween-20 surfactant. Tomorrow the tree will get a deep watering. Lastly, 30 days before expected bloom (mid to late January) the tree will be foliar sprayed with urea to supply the extra energy required by the blooms for a good fruit set.
