Two years ago, the people in charge of landscaping my house planted a very short laurel hedge (2 feet high) along the outside of my picket fence. I have watered and fertilized it, but it has hardly grown an inch, and I'm wondering what I can do to make it grow faster. I've also noticed that they produce a lot of seeds/berries. Should I be pruning these? Please help me, I need some privacy in my backyard soon!
