Wow, Lisa, I am so jealous of your invasive silk trees. I have a few seedlings that have barely grown during the past three years. In California, it seems they take a long time to get established out in the open, in poor soil and with little irrigation. Yet, I see them growing in freeway medians, apparently without irrigation, and they grow pretty fast once they get a few feet tall. They cast such a nice, light shade.
I would use these and black locust for cutting down the frost, rather than Autumn olive. Isn't that invasive where you are? Are the silk trees spreading by seed? I wouldn't be too excited about that.
