Answer: Forsythia is normally a large shrub in the six to eight foot range or larger. Unfortunately it is virtually impossible to maintain it at two feet -- it grows almost as fast as you can prune it, pruning stimulates growth, and worst of all, since it blooms on old wood, you will be limiting the blooms you get next spring. I would suggest you consider replacing it with something that will stay in the size range you have the space for. I'm sorry I can't be more encouraging.
