Funny you should mention that, because not even a full 24 hours after the first picture...
Sproing sound effect, etc. ...I think they both gained another fucking inch, too. ...What have I done.
I can only tell you what I did and apparently it’s been... working out.
Buy a random healthy-looking ginger root at the grocery store
Let it dry out on a counter for about 2 weeks
Place it in a shallow bowl and fill with water until a little over halfway up the ginger root; change out water daily, occasionally flip over for about a week before planting
Absolutely fucking guess as to which way the stalks are going to grow, though apparently it’ll self-correct without too much problem
Place in a pot, just cover with well-draining soil so no part of the root is exposed (I used a succulent/citrus soil)
Keep it in a warm place with bright indirect light, keeping the soil moist but not wet; I used a terra cotta pot and currently water it once a day to make sure it’s not too wet or too dry because apparently they can rot easily but need the water and humidity
Wonder what you did right but refuse to live in fear of the tall weird grass growing right outside your door
Ta-da I guess..?
