Bare Root Turmeric Plant - USDA Certified Organic
Quantity in Stock:
(Out of Stock)
Our turmeric seed rhizomes have been pre-sprouted (active growing points and roots) in the greenhouse to lengthen the growing season and are ready for planting in the ground or in containers.
Turmeric is a rhizome that grows underground from a seed piece (sometimes called the "mother"). The seed rhizome looks similar to the mature turmeric you find in the grocery store however unlike the supermarket ginger, this seed turmeric is certified disease-free and certified organic.
Turmeric is a tropical plant with a long growing season and the seed is pre-sprouted in the greenhouse early in the year to insure a harvest before the weather turn cold. The rhizome is generally harvested in late October through November in order to enjoy the fresh baby turmeric before it develops a thick skin.

Turmeric plants require warm soil, room to grow and plenty of fertilizer. Turmeric can be grown in the ground or in containers.

KEYS TO SUCCESS:
Do not plant outdoors until soil temperatures are at least 55 degrees F and the air temperature is warming into the 70’s.
Turmeric does not like any weed competition!
Turmeric requires three to four fertilizer applications during the growing season (see “FERTILIZING below).
Turmeric plants can grow 3' to 4' tall and the rhizome can spread up to 1 foot. Give in-ground plants plenty of room a use large containers or flexible grow bags for container grown plants.
Turmeric likes plenty of moisture but does not like wet feet. Make sure your soil, whether in the ground or in a container, is well-drained.
PRE-SPROUTING YOUR TURMERIC SEED
Pre-sprouting your turmeric seed indoors gives you a jump start on the long season required to grow ginger.
To pre-sprout, place the turmeric seed in a shallow tray lined and covered with wet coir (ground coconut husks). Keep watered and warm until your outdoor growing conditions are ideal and the pre-sprouted seeds can be planted in the ground.
If you are growing in containers, use the same technique directing in the containers until the conditions are right and the containers can be placed outdoors.
PLANTING IN THE GROUND:
Plant in rows or beds three feet apart
Dig a trench min. 6 inches deep and mix fertilizers/compost in the bottom of the trench
Place pre-sprouted turmeric seed 5 inches apart in the trench
Cover with approx. 2 inches of soil
PLANTING IN CONTAINERS:
Use well-drained, soilless media in containers. We recommend using a good quality, low-salt cocopeat (also called “coir”).
Use flexible grow bags or large pots to allow the rhizomes to grow up and out.
To plant, fill the bag or pot with 4 inches to 6 inches of soilless media and mix in fertilizer and gypsum. Cover with approx. 2 inches of media.
Turmeric enjoys partial sun – strong morning sunlight and afternoon shade or dappled shade all day. Turmeric can be grown in full sun, but make sure the soil temperatures do not get above 90 degrees F in the summer.
Turmeric needs plenty of moisture, but does not like to sit in wet soil. Amend heavy clay soils to allow good drainage. Water plants enough to keep evenly moist without drying out.
Use a mild, balanced fertilizer (such as a 5-5-5 or 4-6-4) at planting time and three to four times during the growing season.
Well-aged compost is beneficial, but do not add materials that are actively decomposing. Decomposing materials will use nutrients in the soil and may cause soil to heat up. Compost alone will not supply all the nutritional needs of turmeric.
Apply fertilizer at a rate of 1 to 2 lbs (depending on soil fertility) per planting row foot. A good quality composted poultry-based manure is commonly used.
Early in the growing season, turmeric appreciates more nitrogen to support leafy growth. In August and September when the rhizomes are forming, ginger benefits from added potassium.
Beginning in late October and/or with cooler weather, the turmeric tops will begin to die back. For baby turmeric, harvest the rhizomes by loosening the soil approximately 12 inches from the base of the plant with a shovel or garden fork, then grasp the stems near the ground and pull the entire plant from the ground or container by the stalks.
Rhizomes left in the ground after the tops have died back will start to form a thick brown skin.
Harvest yields depend on fertility, water, competition with weeds, and temperatures. Yields typically range from 1:8 to 1:12 ratio of seed to harvest. .
