I’ve been growing Musella in a larger pot as well. It performs much as it does in the ground reaching similar size, getting along with comparatively little water. This plant suffered no leaf scorch even during our record breaking streak of 108º, 110º and 116º in late June ’21. It was protected in shade in the afternoon. Here it sits on the deck next to my Musa accuminata ‘Zebrina’, a tropical, which did suffer alot of marginal leaf burn, even with daily watering of its pot during the hottest stretch.
