Answer: You can keep both your ficus and your flowering plum small and compact by carefully trimming them each year. You can cut back each branch by 3-6" on your ficus and it will get bushy and nice. You can do the same with your plum tree. By cutting each branch back by just a few inches you'll keep it looking healthy and happy and you'll be able to keep everything small so it won't outgrow it's planting space.
Best wishes with your trees!
