Go grab that sad piece of ginger from your fridge. Give it a chance. What do you have to lose? Worst case, you get a science experiment in a jar.
Best case? You get a beautiful green plant that might give you fresh ginger in a year. But even if it doesn’t, you’ll have a great story about the time you grew a plant from a leftover knob.
And if anyone asks, just say you’re rhizome-ancing. They’ll be impressed. Or confused. Either way, you’re winning.
Now go get that jar. Your ginger is waiting.
