Q.fig tree growing
My mother-in-law planted a fig tree 2 yrs ago and it’s only a foot and a half tall, maybe 2 ft in diameter. It has beautiful leaves and a few pruned branches. She asked us to take it. We had to cut the tap root plus a couple other hardy roots. We put it in the ground a few mins after removing it. Please help keep this tree and tell me how to get it growing!

Here is a great article about growing Fig trees.
Make sure your watering daily to get the tree established.
