Trees have long root systems that grow faster than vegetables. Therefore, in order to grow them in containers properly, you must choose the right type of tree and pot size.
Use trees that work well for indoor growth like calamondin citrus, fig, evergreen, and rubber trees as a starting point, since they are already known to thrive in pots.
Pay attention to the maximum size that the tree can grow, along with how long it takes to mature. Some may become too large for containers after a few years.
You also must consider how the tree and container’s size affect your ability to move it around. Small pots are easier to move while large containers are best kept in one spot.
