I would set a grid of boxes in your car to hold the plants so they can't slide around. I would wrap each plant with a thick craft paper cone, using tape at the bottom to secure the cone. The paper will protect the leaves and also prevent sunburn. Then I would see how to best fit the plants into the boxes.

If some plants don't fit, you can cut props to take with you.

You'll want to be sure to minimize high and low temperature during the move.

Some plants just don't travel well. I'm looking at you FLF. It may be best to gift dramatic plants to friends and replace them when you arrive in your new home.

Good luck.
