Hey, I've got a small cutting with 5 leaves. At first I planted it in a normal soil... one leaf at the bottom has got dry yellow and fell. I cut it again, let it dry and plant them in a sandy soil. Another leaf just fell by accident. So there's 3 left. But I'm in a dry winter (13/20 C degrees). I've been watering them, no changes in the leaves (they seem healthy) But no roots are coming out, and I'm afraid it's rotten. What do I do?? thank you, guys.
