Yes, you can absolutely install casters on the bottom of a heavy urban planter box to greatly improve its mobility. This is a popular and practical solution for moving large planters on patios, rooftops, or balconies. However, doing it correctly is crucial for safety and plant health. First, choose heavy-duty, locking casters with a load rating that exceeds the total weight of your filled planter—soil and plants can be surprisingly heavy. Attach the casters to a sturdy wooden or metal frame (a "dolly") that the planter sits on, rather than directly to the planter itself, especially if it's ceramic or concrete. This distributes the weight evenly and prevents cracking. Ensure the frame or caster plates do not block the planter's drainage holes. Always engage the wheel locks when the planter is in its final position to prevent unwanted movement. With the right casters and a solid frame, you can easily rearrange your urban greenery for sun exposure, cleaning, or simply a new look.
