Light:
Tradescantia prefers bright, indirect light, but it can also tolerate low light conditions. Avoid direct sun, which can scorch the leaves. If your Tradescantia is not getting enough light, its leaves will become pale and it will start to stretch and become leggy.
Water:
Tradescantia prefers evenly moist soil, but it can tolerate periods of drought. Water your Tradescantia when the top two inches of soil feels dry.
Soil:
Tradescantia is not picky with soil preference and standard commercial mix with perlite is suffice. A good DIY mike to help your plant thrive will have coco coir, perlite, and bark.
Humidity:
Tradescantia prefers average household humidity, but it can tolerate a wide range of humidity levels. To help this plant thrive, maintain humidity between 60-75%.
Temperature:
Tradescantia prefers temperatures between 60-80°F, but it can tolerate a wide range of temperatures. Protect your Tradescantia from cold drafts or sudden temperature changes.
Fertilizer:
Fertilize your Tradescantia once a month with a general purpose indoor plant fertilizer. It is often best to dilute fertilizer to half strength. Drastically cut back on or do not use fertilizer during the fall and winter when growth slows.
