So I took some stem cuttings recently from the tops of several of my biggest plants. I know they can take months to root, and I don't see any yet - it's only been two or three weeks. But, several cuttings are already opening new leaves. Does that indicate success? The bottoms of the cuttings are browning a little right around the wounds, and while the rest of the stems look good, the cut parts make me feel a little uneasy. Anybody care to share their experiences?
