Tradescantia plants hail from warm, tropical regions, so they don’t like being placed near draughts or kept in chilly rooms. They don’t like to be very dry and neglected. If they lose too much water and their potting mix is left to completely dry out, their leaves may start to yellow and turn brown.
Although your inch plant AKA Tradescantia loves moisture, it won’t be happy if it’s sitting in water in the ceramic. Be careful not to over-water your plant and be sure to pour any excess water away.
To maintain its beautiful purple colour, make sure it gets good light. A sunny window sill is perfect. If your plant doesn’t have access to enough light, the leaves will fade, becoming dull over time.
