Growing Tips
Plant rhizome pieces (fingers) with 2-3 buds each; pre-sprouting in warm, moist conditions improves establishment rates.
Mulch heavily to conserve moisture and suppress weeds; turmeric requires consistent soil moisture throughout the growing season.
Harvest 7-9 months after planting when lower leaves turn yellow and dry; cure rhizomes by boiling for 45-60 minutes then sun-drying.
