Misting the tree can be done regularly, especially after the tree has been repotted because it benefits from air humidity. Fertilizing Use normal organic fertilizer pellets every month during the growing season or a liquid fertilizer every week. If you’d like to see strong growth you can apply some higher nitrogen levels in the spring.
