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.
Seed Germination. Soil temperature has an effect on how quickly seeds germinate. If the soil is at 75 degrees Fahrenheit, seeds usually germinate in about seven days. Cooler temperatures slow germination, with seeds in 60 degrees F soil taking two weeks to sprout.If the soil temperature goes down to 50 degrees F, seeds take about 43 days to germinate.ill the pots with growing medium to within 1 inch of the rim. Sow seeds 1/4 inch deep and spaced 1 inch apart, or about two or three seeds per pot.
