Moving large urban planer boxes requires careful planning to protect both the containers and your plants. First, assess the size and weight of your planters. For very large or heavy boxes, it's often best to remove the soil and plants separately to make them lighter and easier to handle. Water the plants a day or two before the move—not on moving day—to avoid excess weight and mud.
For the planters themselves, empty them completely. Clean the interior and exterior, and let them dry. Use moving blankets, bubble wrap, or cardboard to protect the finish from scratches during transit. Secure the wrapping with packing tape or stretch wrap.
Your plants need special care. Gently remove them, trying to keep the root ball intact. Place the root ball into a sturdy plastic bag and tie it at the base to contain the soil. Transport smaller plants in cardboard boxes to keep them upright. For large shrubs or trees that cannot be removed, you may need professional help.
When loading, use a sturdy dolly with straps. Always lift with your legs, not your back. In the transport vehicle, place the planters against a wall or stable surface and use straps or ropes to secure them from shifting. Never stack heavy items on top of them.
Finally, replant as soon as you arrive at your new home. Give your plants a thorough watering to help them settle into their new environment. With proper preparation, you can successfully relocate your urban greenery.
