Fiddle Leaf Fig is a Ficus that needs to be positioned direction in front of a window that will receive direct morning or afternoon light. A north facing window is best. Watering needs to be done once a week. A good rule of thumb is to wait until the top 2-3 in. of soil are dry and then give the plant a thorough watering. If it's in a planter with a drainage hole, this means watering until you notice water dripping out the bottom. However, don't let the drip tray sit full of water, as this allows root rot to set in easily.
