Still, utilize fertilizer balls/tabs if plants show signs of deficiency.
For any rooted plant, let mulm accumulate around the base. This will break down and act as a natural fertilizer, though if the plant is large and a heavy root feeder, such as a sword plant, a root tab is ideal to bury next to it to get it going. From there, accumulated mulm will generally do the rest. Still, utilize fertilizer balls/tabs if plants show signs of deficiency.
