Use paper around the base of the pot to hold it in place. Next, cushion branches and leaves of the plant with soft paper. Finally, punch air holds in the sides of the box and loosely fasten the lid. Set the boxes upright and clearly mark the lids to avoid putting them into the van with the furniture and your other belongings. If you follow this procedure, your plants will be ready to travel safely for up to four days.
Many states regulate the transportation of certain plants.
Traditionally, California, Arizona, and Florida have the most rigid restrictions. Check with your State Department of Agriculture or Department of Natural Resources to find out the rules and regs of your destination state. If you find out that you cannot take your plants along, consider taking cuttings instead. Place them in a sterile mix, or in a plastic bag with damp cotton or paper towel. The cuttings should survive several days' travel and be ready to take root in your new home.
