Cultivation
Rice thrives in moist to wet conditions and requires light to heavy soils with a pH of 7–7.5. It is best suited for cultivation in areas that are warm and temperate, though it can be hardy in temperate regions. Rice prefers full sun but will tolerate partial shade. For successful propagation, plant seeds directly in the ground after all danger of frost has passed. Water regularly to keep the soil consistently moist. Harvest the edible parts when the grains have turned golden brown and are fully mature.
