When you're shopping for rhizomes to plant, be sure to look for the plumpest varieties and budding leaves to ensure the easiest grow. Before you plant them in the soil, place them in a glass jar misted with a little water. Keep the jar in the fridge for a few days.

Once you have fresh rhizomes in your refrigerator, it’s time to prepare your pots. Even though the rhizome sits on or near the surface of the soil, the roots will extend deep into the pot. Be sure to choose a good pot to start, like a gallon size.
Mix a good blend of dirt. My “special mix” is ⅓ existing soil or organic potting soil, ⅓ pine bark mulch (I used old applewood mulch last year with great results), and ⅓ compost or manure. If using manure, be sure it’s well aged. You can also throw in a handful of slow release fertilizer.
Mix the soil well and water before adding to the pot.
In the bottom of the pot, add about 3-4 inches of soil. Dampen again and add soil to 3 inches below the top of the pot. Place your rhizome on the soil and lightly cover. Water once more and place in a sunny spot. You can place them outside if the nighttime temperatures are above 50°F. If not, then place in a sunny window. Light is not key now – heat is most important in the beginning. This planting method will work well with both turmeric and ginger.
You can plant both turmeric and ginger in the ground, but if you live in an area with bad soil, it must be amended first. I suggest the above mixture for in-ground gardens too.
As stated above, wait until the nighttime temps are above 50°F before planting in the ground. Use the above instructions to plant the rhizomes in the same way. Keep well watered until established.
NOTE: Be aware that both ginger and turmeric can be invasive if grown in the ground. Keep an eye on your plants, and if it starts to creep outside of the garden boundaries, place a shovel where you want to stop the growth and stomp on it! These rhizomes can be very tough, so it may take some work. Anything outside the boundary line can be used or replanted.
Both turmeric and ginger are tropical, heat loving plants. Some years it takes until July for turmeric to put out leaves, so don’t give up on it too soon. Ginger will grow faster, and by summer’s end, it could reach 8 feet tall with numerous white fragrant blossoms. It will take a few years for the plants to reach a size from which you can harvest rhizomes on a regular basis, but it will be worth the wait.

Fresh turmeric and ginger are great to have on hand for both food and medicinal purposes, so if you don't have any of these excellent plants at your homestead, it's never too late to start. Plant a garden and soon you'll have plenty of plants that'll come in handy when SHTF. You can use them to eat, share with friends, and, of course, survive!
