Planting flowers in containers
Recently I purchased packs of flower seeds (Aster, Calendula, Alyssum, Bachelor's Button, Balsam, Morning Glory, Gaillardia, Marigold, and California Poppy) and I had three questions.
First can any of mentioned flowers be grown in pots? if so what size. Second do any of these flowers need fertilizer? I read that Marigolds don't but do any of the others need it?
Thank you for any help, I am rather new and at this and still looking around to learn more.
