Horizontally growing shrubs
Hello, I am a new gardener and last year I bought a number of bushes to make a flowering bush screen, with the idea of growing to a hight of six or seven feet. A number of the bushes are growing horizontally, like ground cover and I have no idea why. Forsythia and Wilegia are the worst culprits and I have two of each. I'm totally perplexes and need advice please anyone.
