Do not attempt to transport plants over international borders.
A couple of weeks before your move, prune plants to prepare for packing. Consult a florist or a plant book on how to instructions.
A week before you move, put your plants in a black plastic bag with a bug/pest strip, conventional flea collar or bug powder in the bag before you put the plant in. Close the bag and place in a cool area overnight. This will kill any pests on the plant or in the soil.
The day before you move, place the plants in cardboard containers. Make sure they are held in place by dampened newspaper or packing paper. Use paper to cushion the leaves and place a final layer of wet paper on top to keep them moist. Water the plants normally in summer, a little less in winter.
On the day of your move, set the boxes aside and mark “DO NOT LOAD” so they won’t be taken on the moving van.
On the day you leave, close boxes, punch air holes in the top and load in your car.
When on the road, be careful where you park your car. Look for a shaded area in the summer and sunny spot in the winter.
Unpack the plants as soon as you can after arriving. Remove plants through the bottom of the box in order to avoid breaking the stems. Do not expose the plants to too much sunlight at first. Let them get accustomed to more light gradually.
If you must leave your plants behind, then take cuttings and put them in a plastic bag with wet paper towels around them.
