What size container for Zinnias and Dahlias?
I am trying to grow flowers from seed for the first time. A coworker told me the zinnias I planted aren't suitable for containers. The zinnias I planted are supposed to grow to 30 - 36 " and have 4 - 5" blooms. The dahlias are supposed to grow to 20". Each say they should be placed 18 - 24" apart.
Can these be grown in containers? If so, what size container do I need? What size container would I need for more than one zinnia of this size? Thanks in advance. They are such pretty flowers, I hope I can get them to bloom in containers!
