Last year I put a plantain plant in a pot to see how it would do, well it just set there and produced seed stems, never got any new leaves.I set it off to the side last fall and forgot about it.Look at the pot now.I should have used a larger pot, not sure how I am going to separate them, probably use a spoon and put a spoonful in 6 inch pots then thin them as they grow.---The cherry blossom tree is a little over 40 years old, I haven't trimmed it back for two years.I need to do that this year. I wish it kept the blooms all summer.
