Your mission starts at the supermarket. Pick a plump, firm piece of ginger with little bumps (called “eyes,” like a potato). Avoid anything that looks like a mummified alien hand. Now, the important trick: soak that baby in warm water overnight to wash off growth retardants—chemicals the shops spray on so your ginger stays sleepy and dead.
After its spa day, cut the rhizome into chunks, each with at least one eye. Let the cut bits dry for 24 hours so they form a callous. This prevents rot. It’s basically putting a tiny bandage on your future ginger plant.
