I have 2 urban (philadelphia) planters.

29"x15"x24"

and

26"x15x24"

with poor to no drainage.

I would like to add a short evergreen tree to both.

1. Are there any evergreen TREES that stay 4' or below or

2. Can you trim trees to keep shape but also keep them 4' or less

3. What might be a nice low to the ground addition to add into the planter to bookend each tree?

4. Is river rock and charcoal underneath potting soil/dirt a good foundation for the trees?

Thank you!
