Brand new to growing plants and got these coneflower starters (Powwow wild berry) at a plant sale without knowing anything about them. What size of a pot do I need for them?? I tried to search online and asked ChatGPT and kept getting different answers. I ended up potting 2 of the starters in the 16”x13” pot I got. Is it big enough? Can I put the rest 2 in there (4 starters in total) in the pot cause the pot looks ridiculously big now 😂 all tips and advices are welcomed
