Q: I grew up in New Orleans and we had mimosa trees. I have several random sprouts in my yard but I don’t think they will grow into a real tree anytime soon.

A: Mimosas easily grow here but despite their cute pink flowers, many gardeners consider them a short-lived weed tree. They are very susceptible to disease and their limbs break readily. Culturing the sprouts is your best bet. Move them to appropriate spots this fall and fertilize in April and June to accelerate growth. As far as I know, no nurseries sell mimosa trees.
