For ideal Tradescantia Tricolor care, give it well-draining soil that will partially dry out between waterings. Fertilize with a good mix of peat, compost, mulch or humus, bark, pumice, or perlite. It thrives best in temperatures between 65°F to 75°F (18°C to 24°C). Temperatures should not drop below 50°F (10° C). The Tradescantia Tricolor wants bright light but not direct sunlight. Placing it near to a south-facing window is ideal.
