Roots above the ground. That is a little bonsai tree. The Ficus microcarpa 'Ginseng' is a charming addition to your living room. The plant is hardy, although temperatures of 18-23 degrees are ideal dry air or colder environments should not be a problem. Water the ficus twice a week in the summer and once a week in the winter, to keep the root ball moist. The plant does like light, but not strong, midday sunshine. Morning and evening sunshine, however, are fine for the ficus. To give the fig a boost, put it in the garden for a bit on a warm rainy day. The plant will perk up nicely!
