Comfrey as forage
I have a question. We have a bunch of poisonous, invasive leafy spurge. It has mainly been growing where the ground is more damp and hasn't spread to drier areas yet. I know that it can, but it hasn't here over the 5 or so years that it has been noticable. It was probably brought here by mallard ducks one wet summer.
It can kill livestock eventually as they graze on it. Ours have grazed it as our pasture is small. I think that there is a lot of it in our small pasture, but any amount of it is bad IMO. The municipality would want to spray it if they knew, but I know spray doesn't kill it. A neighbor said mowing does. We have noticed that constant grazing hasn't, and I would consider that as a natural mowing job.
I hear so much about comfrey. It is considered invasive, but excellent forage for pretty much all animals, and I have read that they enjoy it. Now, most of the area affected is partially shaded, but getting sunnier as trees die off (for various reasons). I would like opinions...
1. Could this compete with & choke out the leafy spurge?
2. Would it spread beyond even if regularly grazed?
2. Is this a good idea? Am I just asking for other problems if I do this?
