I recently purchased a house and the previous owners had really neglected the yard. On the slope of the house is ivy which I actually like (I know it is invasive). I would like to keep the ivy but how do I trim it? I got all the leaves and debris out of the ivy this weekend but now it looks worse! It is just long brown vines with only a few leaves at the very end of the vine. I heard that ivy comes back nicely if you run a lawnmower through it but there are soo many layers of vines, there is no way I could put a lawnmower through it. If I just trim it all back, will the ivy come back? Or will new leaves sprout from the brown vines now that I removed the leaves that were blocking the sun? I am new to this gardening thing so any advice would be appreciated.
