In this video I show how we apply fertilizer to dragon fruit. We use a ratio of DAP, Urea and Potash, mix it well and apply it to the root zone of the plant. Keep in mind that dragon fruit roots don’t spread wide, most of the feeder roots are in 1 feet radius of the plant so apply your fertilizer accordingly. Also, please don’t dig the soil to apply fertilizer because you will damage the root system that way. Just apply it on the surface and add some soil on top and then rains and plan’s root will do the rest.
