When your sister catches you eyeing her string of hearts, so she chops off the bottom half to give to you for propagating

My sister's string of hearts is hung from her ceiling and the bottom touches the floor and it's thick and has tons of tubers. I asked her, "how often do you water it? How often do you fertilize?"
Her answer:
"oh…. uhhh I water it when I remember to. Idk, sometimes I forget about it. It just does this"
