Balls-on-a-string

I do not have green fingers. But I have some plants that survive my not-so-tender custody. Hearts-on-a-string (Ceropegia woodii)  belong to them, I have been blipping them before. They also grow fast and after some years they get a little ugly. But then I can easily fix a new plant. As the plant gets older, pale yellow balls come on the strings and I pinch some with a little of string on each side, put them in a pot with soil. After a few weeks, I have a new plant. It is so easy.
