Place your Ruby in a location where it can receive bright, indirect light. Too much direct sun will scorch the leaves, but this plant will not fare well in low light spaces. Placement a few feet removed from southern or western exposure is ideal. 

Your Ficus Decora Burgundy will appreciate consistent watering. Allow the top inch of soil to dry out, then water thoroughly. Water less often during the winter, as growth naturally slows and your Ficus Tineke requires less water.
