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.
Planting. Spinach does best when growing in moist, nitrogen-rich soil. Spinach plants form a deep taproot; for best growth, loosen the soil at least 1 foot deep before planting. Sow spinach seed as early as six weeks before the last frost or as soon as you can work the soil.Prepare the soil the previous autumn, and you can drop the seeds in barely thawed ground. In areas with a long, cool spring, make successive plantings every 10 days until mid-May.pinach plants form a deep taproot; for best growth, loosen the soil at least 1 foot deep before planting.
