Moving a plant successfully involves packing it carefully but also anticipating the conditions you will encounter during the trip in the car. 

Your plant should be treated to a good watering the day before the trip. Packing materials should include a box that holds the pot with packing paper around it to keep the container from shifting and then a larger outer box with some scrunched packing paper to hold the inner box in a fixed position and contain any delicate branches. Take your time packing so that branches are gently cushioned by the paper and protected by the box. Leave the box open on top to allow air circulation. When you place it in the car, keep it away from heat or air conditioning vents and anything that could topple on to it.

If you are planning to stop along the way, be aware of external conditions and do not leave the plant exposed to heat or cold beyond its normal tolerance. A parking spot in the shade will help if you make a quick stop on a hot day.

One other thing to think about: if you are moving to or driving through a state with a large agricultural presence, like California, there could be an inspection at the border. Have your plant in a position in the car where the agricultural inspector can see it with minimal disruption for an easier trip. Read about any plant restrictions on the state's website as you plan your move.

Once you arrive at your new location, prioritize relocating the plant as you would a pet. Give it sun and water while you move in your belongings. Place it in an environment as similar as possible to the place in which it flourished in your present home.
