I've taken to pulling up rhododendron pretty much any time I come across them. It seems sometimes like a drop in the ocean as there's usualy well established ones nearby but if they're under a foot and half or so they pop out cleanly. The roots seem quite tough and stubby and don't leave anything behind if the soil's loose enough.
Between there and three foot they can still be persuaded out but sometimes a bit of root will break off. Does that mean it's won and will be back?
...and what happens if you just chop 'em and don't poison the stump? I've heard you have to return time-and-time again cutting the shoots but how long is "time-and-time again"?
Basicaly, anyone got any rhodie killing tips for an enthusiastic amateur?
