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.
Check the outdoor temperatures. While sunflowers can be started indoors, they work best if they're moved outdoors within a week. They grow best at temperatures between 64 and 91ÂºF (18â33ÂºC), but you can give it at lower temperatures, once the last frost has passed.unflowers are annual plants that produce large or small yellow flowers in the summer. Sunflowers are very popular because of their beauty, and because they are easy to grow. Planting sunflower seeds in the spring can be a fun activity for adults and children.
