The most common way people kill their Nanouk is consistently overwatering. Overwatering is very bad for most houseplants. Consistent overwatering will cause root rot, which essentially suffocates the roots and kills the plant. If your Nanouk shows signs of slow growth, mushy stems, and wilting, yellow, distorted leaves, you probably have root rot. Try this: Take your plant out of the pot. Wash away all the old soil. Cut away all the rotten and damaged roots. Place your Tradescantia in fresh, well-draining soil. Give it bright, indirect light, and some humidity. The above steps will give you a chance to save your plant. Prevent future root rot by using well-draining soil and watering your plant only when the top inch of the soil is dry.
