I’m not really into flowers, so I’m looking for some advice. I have grocery store orchids from two years ago that are always in bloom. They have 3-7 flowers each basically nonstop. Unfortunately they have far outgrown the 17" stakes I put in their very small original pots and I don’t know what my best option would be. I water them with two ice cubes once a week and I’m not looking to really increase the level of investment I’m putting in. I know I’m not doing a lot, but I’ve not had to feed them or mist them or any of the other things I keep reading online and I’d like to not have to worry about that. My main issue is that they are getting way too tall. I read that you can cut the stems, but I’m worried that any cutting will prompt additional flowering and maybe a need for more water or food or something that I likely won’t be able to recognize causing them to die. I also keep seeing people talk about pots with holes and special airable soil, but they are in little plastic cups and I can lift them straight up and the soil is basically a solid almost styrofoam-like consistency so I’m not sure I believe what I’m reading. Any advice or suggestions to preserve the low maintenance aspect while trimming and possibly repotting would be greatly appreciated. I looked online and this post is my exact same experience to a T: https://www.reddit.com/r/orchids/comments/1igq42f/my_orchid_is_over_3_feet_tall_and_not_sure_what/

Most comments there say to cut the spikes so it focuses on leaves and roots, but I really don’t think they have enough space for more leaves or roots, and I’m worried that repotting will ruin whatever my streak is with keeping them alive on just ice cubes since that seems uncommon. I’ve never kept a flowering plant alive for this long, despite a thriving vegetable and herb garden, so I’m a bit attached. If I cut just the ends of the spikes will it still flower? Should I cut the whole spike and just hope it doesn’t get too big for the pot? Is repotting really as care intensive as the comments suggest?
