Scratch the surface of the growing mixture with your fingertips to roughen it up. Place the princess tree seeds onto the roughened surface of the growing mixture. Space the seeds 2 inches apart.
Mist the growing mixture heavily using a garden hose with a misting nozzle. Let the water soak in. Mist the growing mixture again until it feels moist at a depth of 1 inch. Maintain moisture at 1 inch while the princess tree seeds germinate.
Watch for germination in two to three weeks. Carefully transplant the seedlings into 10-inch plastic pots filled with the soil mixture described in Step 1 as soon as they grow to 1/2 inch in height.
