Regrow Cilantro - Like basil, cilantro can grow roots if the stems are placed in a glass of water. Once the roots are long enough, just plant them in a pot. In a few weeks new sprigs will be starting, and in a few months you’ll have a full plant.
Grow ginger indoors from grocery store rhizomes. After soaking the root over night, bury it with the buds facing up under an inch of rich soil in a shady area. Ginger thrives in moist conditions, so be sure to water regularly.
