I bought an Evergreen Wisteria in October for a new Arbor we built over our patio. My new puppy, who was left in the yard while we were at work began chewing on the branches of my three foot tall (expensive) plant. I started noticing all the leaves falling off and it became quite bare. She managed to chew through each branch. I cut them off so they are now about a foot high and was hoping it would be okay. I figured since it was three foot tall it had been around for a while and the roots might be sturdy. It still hasn't grown any leaves but I am wondering if it is just because we are in winter and maybe it will in spring- even though it doesn't lose its leaves. Any chance it will survive?
