Germinating the Seeds. To germinate staghorn sumac seeds place them in a warm room away from direct sunlight. Regularly mist the soil in the pot with a spray bottle to keep it moist. After germination, remove the plastic wrap and position the pot in a sunny window so the seedlings can grow.
Bury the seeds 3 in. into the soil and tamp lightly. Keep the soil moist. The seeds should germinate and sprout the following spring. Place moist seed-germinating medium into a plastic bag and fill the bag half-way.
