ZZs are such cool plants - and so easy to grow! Tarev, leaf cuttings seem to root more easily if you take the leaf and cut in half. Stick the cut ends of each half into the soil. Keep only slightly moist and sometime in, oh, maybe about 6 to 8 decades it will root and grow a whole new plant! Ok, maybe it's only 6 to 8 weeks(ish), but it FEELS like decades while you're waiting!!
