The home we bought was previously rented out for 5 years and the tennants did nothing to the gardens. I was able to revive the front garden and last year planted perennials and annuals. This year, I need to tackle a very large side area that is just over run with a mixture of perennial ground cover (goutweeed and ivY) and large, tall weeds. The entire length of south side of our back yard is in this state (about 15' wide from the fence and 50' deep). There is also a pine tree covering half of this area. Should I just rent a rototiller and plow everything up? How can I be guaranteed that weeds will not regrow? What is a good type of ground cover to replant? Thanks for your help. Jo
