Hello again, yesterday I bought these little plants of burro's tail and I want to pot them all together in a nice composition, but I'm unsure of what dimension of pot to use. I still have to see how the roots are established. In my mind I want the composition to be full and hanging, but I'm unsure how to start it properly, since I know that when they take a "form" it is really impossible to change that form. Would the pot in the second photo be ok for them or is it too big? I mean, I want them to grow so that's why I thought about that pot. Sorry for my English, it's not my main language!
