The best thing to do is get a soil and leaf tissue analysis to figure out what is deficient. Absent that, I'd add both, not one or the other. For boron, just add a tiny bit of regular old borax. For a large established mat, I use 1-2 teaspoons every 6 months or so, per the Keppler and Rust banana book. Foliar sprays with boron in them are a quick fix for boron deficiency.
