I'd like some advice on a clematis vine plant that was left to grow without a trellis. Without anything to climb on, it has turned into a giant heap in just a couple of short weeks. As you can see from the photo, I installed some garden twine today and tried untangling it, but it is a very delicate plant and hard to untangle without snapping. What is the best course of action now? This exact situation happened with this plant last season, and I was heartbroken to see it happen again this season. I was considering cutting it back so it could grow correctly, but it is now the end of April and I wonder if we have lost it for this season.
Thank you for any advice.
