Ficus-Can They Be Trimmed
I have 2 indoor ficus' that are getting really bushy. Is it possible to trim them?
Of course you can prune the ficus. Cutting (pruning) does not harm any plant, especially a tree.
The above-referenced article is good, I would add only that you determine the shape of the new growth by the direction of the node or branch above which you make your cut. In other words, If you cut back to a small branchlet growing downward, it will continue on that path as it grows; if you cut back to one growing upward, the new branch will be in that position. Same if you cut back to a leaf; if the leaf is on the underside of a branch, the new shoot will come out in that direction, if the leaf is on the upper surface of the branch, new shoots will be also. But it's more effective to cut back to small branchlets, rather than leaves.
Also, you can thin out the interior of the tree by cleaning off (cutting) small branchlets and leaves growing from the larger branches in the interior of the tree.
The following article addresses the rubber tree, but weeping figs need the same procedure: https://www.gardeningknowhow.com/houseplants/rubber-tree/prune-rubber-tree.htm
