|I have 2 mandevilla plants growing in a flower bed and up a small trellas. They both have grown higher and wider than the trellas. Should I put anything on the garage wall to help their climb?|
That is up to you. It is fine to allow them to fall back down the trellis or if you like you can extend the trellis. They do get a bit enthusiastic about growing in your climate, don't they? Perhaps you should plan on installing a larger trellis for next season.
Thanks for the question. Please stop in again soon!
