I water my Fiddle Leaf trees once a week with about 1 cup for the small tree and and 1 1/2 for the large tree. I water them outside since I have kept them in their original plastic containers so the water can drain and the roots dry out a bit (very important if storing in a basket). I put them in the shade and let them air dry before bringing them back inside.
At least once per month, dust the leaves gently with a clean cloth and either spritz with water or wipe the leaves off with a damp cloth. Once a quarter, I use coconut oil on the top side of the leaves to moisturize them and give the leaves a healthy shine. Be careful to only use a couple of drops or swipes from melted solid coconut oil so you don't "clog the pores" of the leaves. They need to be able to breathe and a little goes a long way. You are never supposed to put oil on the underside of the leaves.
Fiddle Leaf trees prefer South Western light so put them by a door or window in that part of your house. You are not supposed to move them around a whole lot, if you do rotate them no more than once a month. We moved one of ours upstairs while we had our Christmas tree up and it got upset. The leaves were so droopy, it just looked hopeless. I finally, gave it more frequent waterings (once a week instead of once every 2 weeks) and moved it back to it's home downstairs and it came back to life.
Tip: If you see the top leaves turning brown that could mean you have a fungus, see your local garden center for product recommendations if you think this is your issue. I have not had this problem but have heard of others who have so I am passing along this info. to you.
Where to Buy?You can visit Lowe's (where I got mine) or Home Depot locally or go online to order one from Home Depot for $29.97! I have also heard some people have found small trees at Ikea so you may want to check them out too.
My Fiddle Leaf Fig trees are loving their baskets. Maybe because it allows more breathing room than a ceramic pot. Plus baskets are having a moment of their own in home decor (or did they every go away?).
Here are my favorite baskets for Fiddle Leaf Fig trees:
