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.
Best Answer: Takes approx 14 - 21 days for sunflower seeds to germinate, depending on the type of S. flower, and weather & water conditions.My sunflower package says Sow in open well exposed soil.eep it well drained and the soil wet. Don't water it too much. My sunflowers seemed to take a long time to come up but after about a month of growing they are about 12 tall. They are very cool plants. Mine are the giant type and should grow about 12 feet tall.
