I have been watering every 2 weeks, and have seen new growth (3 leaves) on one of the lower branches only. The taller branches continue to lose some of their lower leaves, but the loss of leaves has definitely slowed a lot. Will new leaves form where all the lower leaves dropped? I now have 3 tall branches where I have leaves on top, but the majority of the branch is empty... How do I fill those in? The tree looks pretty bare and sad. For the below pic, green is where the new growth is, and red is where we lost a good amount of leaves.
