Anyone out there made a plant cart that can be rolled around and accommodate larger pots? I need an idea how to make something that can handle bigger containers but still be manageable. Here’s a picture of what I’m dealing with. These pots are between 12”-18” wide and tall. I would like to have something that would hold 3 wide x 2 tall, but I’m afraid that might be too big to maneuver. So if you have done something like that, let me know how it works for you.
