Steps to planting sunflowers in Virginia

Follow these steps to plant sunflowers in Virginia:

Select a sunny location with well-draining soil. Prepare the soil by removing weeds, rocks, or debris.

Plant seeds 1 to 2 inches deep, with a distance of 6 to 12 inches between each seed. Cover the seeds with soil and water thoroughly.

Water the seeds regularly until they germinate, usually in 7 to 21 days.

Thin the seedlings when they have grown a few leaves. Leave the strongest seedling in each group and remove the weaker ones.

Provide support by staking the plants when they reach a height of 1 to 2 feet. Use bamboo stakes or trellises to support the plants

Fertilize the plants to promote healthy growth. Use a balanced fertilizer containing nitrogen, phosphorous, and potassium.

Harvesting sunflowers

Sunflowers mature in about 80 to 120 days from planting. Harvest the sunflowers when the petals have wilted, and the back of the flower head turns yellow. Cut the stems with a clean, sharp knife, leaving about 6 to 12 inches of stem. Hang the sunflowers upside down in a dry, well-ventilated area to dry for a week or two.
