Grew this from seeds in since 2020, I like it. I don’t care if it fruits ever. Wondering if I should repot it as it get crazier every year. I’ve seen adult plants grow along rocks and farms grow them on wooden towers. I don have much space in my place for a massive cactus tower but would entertain the idea of a large rock for it to crawl on. Can you guys recommend tips?
