Gathered all the materials needed.
Cut a plastic refuse sack down so that it will fit snugly inside the suitcase and form a lining. Push the sack neatly into the corners. Use a pair of scissors to cut some holes in the plastic for drainage. If you want to keep the suitcase in good condition, simply leave the lining intact and make sure you do not over-water.
Put some crocks in the bottom of the suitcase, covering the holes in the plastic to help improve the drainage.
Fill the suitcase with potting mix, stopping just short of the top of the refuse-sack lining.
Take the plants out of their plastic pots and position them in the suitcase until you are happy with the arrangement. Scoop out some of the potting mix and push the plants into the holes, firming around the plants to keep them in place.
