Aimee Stern. I have been working with scientists and engineers on explaining their research and other work to the general public for almost a decade. I've explained the science of many things and how they connect to the real lives of real people.
Sunflower seeds are best sown outdoors directly into the garden. After planting, cover them with a screen, as the birds and animals love to dig the seeds out. You can also start them in a seedbed and transfer them when they are small. If you plant sunflowers indoors, use individual peat pots. Start two to three weeks before the last frost date for your area. Plant one or two seeds per pot, thinning to one before planting outdoors. If you grow them to feed the birds, look for seedlings growing near the base of last year's crop.
Can I Grow Sunflowers Wher I Am? Sunflowers grow best in locations with full sun. They are remarkably tough and will grow in any kind of soil as long as it is not waterlogged. They do fine in soils that are slightly acidic to somewhat alkaline (pH 6.0 to 7.5).
