I have a southern facing side of my house that I want to plant some rhizomes so they can grow uo the house. The bed is about 30 ft long but it only 3 feet wide. I was thinking about cutting the bottom off of 5 gallon buckets and planting those in the ground with the rhizome in the middle. I'm hoping the root system grows deep enough and won't crack the concrete. Can hop roots even crack concrete? Hopefully I am just worrying over nothing.
