I have two cacti that are very unhappy with me. The first one is 2 in one and one has died, should I remove it somehow? From the roots or just cut it down? The second actually just grew out this new stem on the left as you can see in the picture but the flower is clearly dying off. Should I do something about that? Seems like the plant itself is still salvageable? Any advice would be greatly appreciated, I’m terrible with cacti but these were gifts!! 🥲
