Ficus Retusa, also called Cuban Laurel, is a common bonsai variety that can also be found in a larger potted form. Choose a growing location that receives full to partial sunlight with a temperature above 55 degrees F. Keep the plant away from drafts or areas with temperature fluctuations. Move the plant to a partially shaded area if the foliage appears dried from too much sunlight. Bring the plant inside when the temperature drops below 55 degrees to prevent stunting growth or killing the tree. Water only once the soil becomes slightly dry to prevent over-saturation that promotes root rot.
