Did you do something to the bottom of the cuttings other than using sanitizer? It looked like you gouged out some of the 'meat' of the cutting....I'm sorry if i missed it in your video!😁
it may appear like that. But, i did not do anything else other than applying some sanitizer. However, if you leave your cutting for a few days then you may notice that the bottom shrinks in a little bit. Update: All the plants survived. Its such a hardy plant i don't think even sanitizer was needed.
