I've grown a ginger plant from a ginger rhizome i bought from the store and i've made another pot with 7 ginger rhizomes planted in it. (some of them have started to sprout)

When i was cleaning out my garage, i found a packet of phosphorus sticks that, the instructions say, should be buried in a pot and "watered as usual"

So what do you guys think? Should i use the phosphorus sticks in my ginger pots?

So sorry if this a dumb question

THANKS
