Hi! This is Rosita, a neon robusta, I bought her last year on july in the same pot of the photos. Even though the pot lacks drainage, I believe she's thriving. I try not to overwater, I've never fertilized, nor repotted, nor added pesticides. Should I repot her? Completely or only part of her? I'm new at this and any advice is welcome. First photo is when I bought her vs. how she's looking right now.
