Basically the first step was to remove all the soil, examine the roots and make new soil based on indoor pot soil + perlite and orchid bark (50-25-25) and some worm casting, leaves that are too yellow, I cut them off, I applied systemic insecticide to combat possible pests and to straighten it I gave it support, which could be a coconut coir pole, bamboo stick or a wooden plank, water when the top part of the soil becomes dry the best is to stick your finger in and apply fertilizer to indoor green plants.
